Ranked by what each one is best at, not by a score we made up. Ratings are what the product showed on Amazon when we last checked — how we rank.

Below: why each one made the list, the numbers worth comparing, and what is wrong with it.

The most useful thing to know before you buy a raised bed is a cost calculation nobody puts in the listing. You are buying a volume of soil, and the soil almost always costs more than the bed.

A four-by-eight-foot bed twelve inches deep holds roughly thirty-two cubic feet of growing medium. Bagged potting or garden soil typically comes in one-and-a-half to two cubic foot bags, so that is somewhere around sixteen to twenty bags for one bed, and you will be carrying all of them. People buy the bed, assemble it in an afternoon, and then discover that filling it is the actual project.

This is not a reason not to buy one. It is the reason to plan the fill before you choose the size, because there are much cheaper ways to fill a deep bed than buying soil for all of it — and knowing that changes which bed you buy.

How to fill a deep bed without buying thirty bags of soil

The bottom third of a deep bed does not need to be finished growing medium, because most vegetable roots never get there in the first season. A layered fill is the standard approach and it works:

• Bottom layer: coarse woody material — small logs, branches, prunings, twigs. It decomposes slowly, holds water, and eventually feeds the bed. This is the traditional approach sometimes called a mounded or layered bed.
• Middle layer: bulkier organic matter — leaves, grass clippings, straw, cardboard, spent compost. It will settle substantially over the first year, so overfill it.
• Top layer: the good stuff, and this is the only part you should be paying proper money for. Six to eight inches of a compost and topsoil mix is enough for almost everything you will grow in year one.
• Then top up annually. The bed will sink as the lower layers break down. That is not a fault; it is the bed working. Add compost every spring.

And if you are filling more than one bed, price a bulk delivery of a soil and compost blend from a local supplier against bagged soil. By the time you need a cubic yard, bulk is usually dramatically cheaper, and a cubic yard is roughly twenty-seven cubic feet — about one four-by-eight bed at twelve inches.

Depth matters more than area, and six inches is the common mistake

The single most common regret with raised beds is buying one that is too shallow, because shallow beds photograph well and cost less to ship. What you can grow is largely a function of depth.

• Six inches: lettuce, spinach, herbs, radishes, and not much else. Fine as a salad bed; disappointing as a vegetable garden.
• Ten to twelve inches: the practical minimum for a general vegetable bed. Beans, peas, brassicas, zucchini, bush tomatoes, most things.
• Fifteen to eighteen inches: carrots, parsnips, potatoes, large tomatoes, anything that wants to go down. Also much more forgiving of missed watering, because there is more water in the bed.
• Twenty-four inches and up: waist-height beds, which are about your back rather than the plants. Excellent if kneeling is a problem, and they dry out fastest of all because there is a lot of surface relative to the ground.

One important qualification: a bed sitting on open soil is deeper than its walls. If you loosen the ground underneath before you fill it, roots go straight down past the frame, and a ten-inch bed on cultivated earth behaves like a much deeper one. A bed on concrete, a patio or a deck has exactly the depth of its walls and nothing more, so on a hard surface buy deep and buy it once.

Width: never more than four feet

The entire point of a raised bed is that you never walk on the soil, because compacted soil is what raised beds exist to solve. So the bed has to be narrow enough that you can reach the middle from either side without stepping in.

For most adults that means four feet maximum, and three and a half is more comfortable. If the bed is against a wall or a fence so you can only reach it from one side, two feet is the limit. Length does not matter — a bed can be as long as you like, and a longer narrow bed is more useful than a wider short one.

Leave paths between beds wide enough for whatever you will push down them. Two feet is enough to walk and kneel; if you use a wheelbarrow, measure it, because a path you cannot get a barrow down is a path you will carry buckets along for years.

Material is a lifespan question, not a performance one

Plants do not care what the walls are made of. What differs is how long the bed lasts and how much attention it needs.

• Untreated pine or fir: cheapest, and typically three to five years in contact with damp soil before it goes soft. Fine if you think of the bed as semi-disposable.
• Cedar or redwood: naturally rot-resistant, ten to fifteen years or more, and the thicker the board the longer it lasts — board thickness matters more than the species. Looks best, costs most in wood.
• Galvanized or coated steel: the longest-lived option in practice, often twenty years or more, and it ships flat which is why it dominates online. The coating is what protects it, so scratches at assembly are worth avoiding.
• Vinyl and composite: effectively immune to rot, no maintenance at all, and it can become brittle after many years of ultraviolet exposure. Good in a wet climate.
• Fabric grow bags: cheap, excellent drainage, dry out very fast, and last a few seasons. Really useful and a different product.

On the question people always ask about metal beds heating the soil: the sun-facing wall does get warm, and beds with metal sides tend to dry out faster at the edges. The soil mass in the middle moderates it considerably, and in practice the effect is manageable rather than disqualifying — mulch the surface, water at the base, and plant the very edge with something tolerant. In a cool climate the early-season warmth is an advantage.

Safety and the things that go wrong

• Never use old railway sleepers, telegraph poles or any creosote-treated timber for growing food. Creosote is a recognized hazard and it leaches. The same caution applies to lumber pressure-treated with chromated copper arsenate, which was phased out of residential use in the United States around 2003 — if you are reusing old boards of unknown origin, do not use them for edible crops.
• Modern pressure-treated lumber uses copper-based preservatives rather than arsenic, and extension services generally consider it acceptable for vegetable beds. If you would rather not, line the inside with heavy plastic sheeting — not the bottom, so drainage still works.
• Wear gloves when assembling galvanized steel beds. Rolled edges help, but panel corners and screw holes on flat-pack steel are sharp and this is the most common injury in this category.
• Soil is heavier than you expect. A cubic foot of damp soil is around forty to fifty pounds, so a small four-by-two bed at one foot deep holds several hundred pounds. Fill beds in place, never move a filled bed, and lift bags with your legs.
• Do not put a filled bed on a balcony or roof without knowing the load rating. This is a structural question, not a gardening one, and the weight above is why.
• On a slope, level the site first and stake the bed. A bed on a slope will bow outward at the downhill wall over a season of watering, and steel panels will deform permanently.
• Line the base with hardware cloth if you have voles or gophers. Not landscape fabric, which they chew through. Do this before you fill, because doing it afterwards means emptying the bed.
• Do not line the bottom with plastic. Raised beds work because water drains through into the ground. Sealing the base creates a waterlogged box.

A note on this category before the list

Raised beds are an unusually difficult category to research honestly. Amazon’s results are dominated by flat-pack galvanized steel kits from brands with no track record and listings only months old, frequently showing very high ratings on a few dozen reviews. Meanwhile the long-established cedar bed makers sit at ratings in the low fours, because a wooden bed that arrives with a split board generates a one-star review and a steel panel does not.

We have included a cedar option that sits right at our 4.3-star floor and said so plainly, because leaving wood out of a raised bed guide would misrepresent the category. Everything else here was chosen for having a review base large enough to mean something.

The best raised garden beds right now

Every rating below was read off the live Amazon listing at the time of writing. Only beds at 4.3 stars or better are included.

1. Land Guard Galvanized Raised Garden Bed, 2-pack — best value

4.6 stars, 2,018 ratings. Two galvanized steel beds, roughly 4 by 2 feet by 1 foot deep each, around 7 cubic feet of fill per bed, flat-pack assembly.

Two thousand ratings is the largest review base for a metal bed kit we found, and the configuration is the sensible one. Two smaller beds are more useful than one large one for most gardens: you can put them in different amounts of sun, rotate crops between them, and reach every part of both from either side without ever stepping on the soil. Twelve inches of depth clears the practical minimum for a general vegetable bed.

Galvanized steel is also the right material for a bed you want to stop thinking about. It ships flat, assembles with a screwdriver, and if the coating is left intact it will outlast several wooden beds.

• Type: galvanized steel, two beds of roughly 4 x 2 x 1 ft, flat-pack
• Why it works: twelve inches of depth, two beds rather than one, and the largest review base among metal kits
• Best for: a first raised bed garden, crop rotation, and anyone who wants to stop maintaining wooden frames

Where it falls short: wear gloves during assembly, because flat-pack steel panels have sharp corners and screw holes. Twelve inches is the minimum rather than generous, so if you want carrots or parsnips look deeper. Avoid scratching the coating during assembly, because that is where corrosion starts. And at 4 by 2 feet each, the total growing area is modest — do the arithmetic against what you actually want to plant.

2. Yaheetech Elevated Wood Planter Box, 2-pack — best elevated for your back

4.6 stars, 2,552 ratings. Two waist-height wooden planter boxes on legs, non-painted natural wood, load capacity around 220 lb each.

An elevated bed on legs solves a different problem from a ground-level bed, and it is a problem worth taking seriously: kneeling. If bending and kneeling is difficult, or is becoming difficult, a bed at waist height converts gardening from something you brace yourself for into something you do casually while standing. That changes how much gardening actually happens, which matters more than any soil specification.

Two and a half thousand ratings is the largest review base in this guide, and a two-pack lets you stand them end to end along a wall or fence — which is exactly the situation where an elevated bed makes most sense, because you can only reach it from one side anyway.

• Type: elevated wooden planter boxes on legs, two-pack, natural untreated wood
• Why it works: waist height removes the kneeling barrier entirely, which is what decides whether the garden gets tended
• Best for: anyone with back, knee or mobility limitations, patios, decks and along fences

What owners complain about: the planting depth on elevated boxes is usually shallow — often six to eight inches — so treat these as salad, herb and shallow-root beds rather than as vegetable plots. They dry out much faster than ground beds because there is no soil below and air on all sides, so plan on watering more often and consider a drip line. Untreated wood on legs, in contact with a damp patio, is the part that rots first — stand them on feet or pavers. And the load rating is per box; do not fill them with heavy wet topsoil, use a lighter potting mix.

3. Keter Urban Bloomer — best for a balcony or a patio

4.5 stars, 3,147 ratings. Resin elevated planter, roughly 32 by 15 inches and 31 inches tall, around 12.7 gallons of soil, integrated drainage and a storage shelf beneath.

Three thousand ratings makes this the most reviewed product in this guide, and it is the right answer for the situation most raised bed guides ignore: a balcony, a small patio, or a rented flat where a permanent bed is out of the question. Resin will not rot, will not stain a deck, weighs little empty, and the drainage is engineered rather than improvised.

The shelf underneath is the sort of detail that sounds trivial and turns out to matter, because in a small outdoor space the alternative is that your trowel, twine and gloves live on the floor.

• Type: resin elevated planter, around 12.7 gallons, integrated drainage, storage shelf
• Why it works: the right product for a balcony or small patio, with proper drainage and nothing to rot
• Best for: balconies, small patios, rented properties, herbs and salads

The downside: twelve and a half gallons is a small volume, which is a salad and herb bed rather than a vegetable garden — one zucchini plant will fill it. It will dry out quickly in summer and needs watering most days in hot weather. Resin can fade and become brittle after many years of strong sun. And check your balcony’s load rating: filled and watered, this weighs a great deal more than it does empty.

4. Vego Garden 17-Inch Tall Modular Metal Bed — best depth

4.8 stars, 759 ratings. Seventeen inches deep, modular panels that assemble into multiple shapes, zinc-aluminum-magnesium coated steel.

Seventeen inches is deep, and this is the pick if you want to grow root vegetables, big tomatoes, or anything that resents a shallow bed — and especially if the bed is going on a patio or over concrete, where the walls are the only depth you get. Depth also buys you forgiveness: a deeper bed holds more water and punishes a missed weekend far less than a ten-inch one.

The modularity is the other genuine feature. The same panel set assembles into several configurations, so you can make a long narrow bed against a fence, an L-shape around a corner, or a standard rectangle, and change your mind later. The coating is a zinc-aluminum-magnesium alloy rather than plain galvanizing, which is a more corrosion-resistant specification.

• Type: 17-inch deep modular steel panels, zinc-aluminum-magnesium coating, multiple configurations
• Why it works: real depth for root crops and patio installations, with a coating specification above plain galvanized steel
• Best for: root vegetables, beds on hard surfaces, awkward garden shapes, and anyone who waters irregularly

What you give up: seventeen inches of depth means substantially more fill volume, which takes the soil-cost problem from the top of this article and multiplies it — plan the layered fill. With 759 ratings the review base is thinner than our top picks. Modular panel systems have more fasteners and take longer to assemble. And it is more expensive than plain galvanized kits, which is what the coating and the modularity cost.

5. 6-Foot Vertical Freestanding Elevated Planter — best for very small spaces

4.8 stars, 1,415 ratings. Vertical tower of stacked food-grade plastic bins, six feet tall, freestanding, small floor footprint.

If floor space is the constraint rather than money, going up instead of out is the answer, and this is the vertical option with a real review base behind it. A six-foot tower occupies about the footprint of a large plant pot and gives you a series of separate planting bins, which suits herbs, salad leaves, strawberries and trailing plants very well.

It is also the most practical answer for a narrow balcony or a courtyard where a conventional bed would block the only route through.

• Type: vertical stacked planting bins, 6 ft tall, food-grade plastic, freestanding
• Why it works: maximum planting positions for minimum floor area, in a format that suits herbs, salads and strawberries
• Best for: balconies, courtyards, narrow side passages, herbs and strawberries

The part that annoys people: each bin is small and shallow, so this is not a vegetable garden — nothing with a serious root system will be happy. Small volumes of soil high in the air dry out extremely fast, and watering the top does not reliably reach the bottom, so watering each bin is a daily job in summer. A six-foot tower is also a wind risk — secure it. And the upper bins shade the lower ones, which you have to plan around rather than fight.

6. Greenes Premium Cedar Raised Bed, 4 x 8 x 10.5 inch — best cedar

4.3 stars, 807 ratings. North American cedar, three-quarter-inch thick boards, dovetailed corner joints, no chemical treatment, made in the USA.

We are including this at exactly our 4.3-star floor and being explicit about why. Cedar is really the nicest material to build a vegetable garden from: it is naturally rot-resistant without any treatment, three-quarter-inch boards are thick enough to last a decade or more, and it looks like a garden rather than like agricultural equipment. A four-by-eight bed is the classic and most useful size there is.

The reason the rating sits where it does is structural to the category rather than to this product: timber shipped flat-packed across a country arrives split, warped or short a board often enough to generate a steady stream of one-star reviews, in a way that steel panels simply do not. If the boards arrive intact, owners are generally very happy with it for many years. That is the trade you are making.

• Type: untreated North American cedar, 4 x 8 ft, 10.5 inches deep, 3/4-inch boards, dovetail corners
• Why it works: the classic size in the best material, with no chemical treatment anywhere near your food
• Best for: a proper vegetable garden on open soil, and anyone who wants the bed to look like part of the garden

Where it disappoints: at 4.3 stars it is the lowest-rated pick in this guide, and shipping damage to timber is the reason — inspect it on arrival and be prepared to claim. Ten and a half inches is adequate but not deep, so loosen the ground beneath it. Cedar weathers to grey unless you oil it, which is cosmetic. And a four-by-eight bed at that depth needs a large volume of fill — see the layered approach above before you price bagged soil.

7. Vita Classic Vinyl Raised Bed, 4 x 4 x 11 inch — best zero-maintenance

4.8 stars, 451 ratings. Food-grade vinyl, BPA and phthalate free, 4 by 4 feet and 11 inches deep, modular and expandable.

Vinyl is the answer for anyone who wants a bed that will look the same in fifteen years with no attention whatsoever — no rot, no rust, no oiling, no splinters, and it wipes clean. A four-by-four square is also an unusually good shape for a first bed, because every part of it is within easy reach from any side and it fits in a garden where a four-by-eight would dominate.

• Type: food-grade vinyl, 4 x 4 ft, 11 inches deep, modular and expandable
• Why it works: actually no maintenance ever, in a compact square shape that suits a first bed
• Best for: low-maintenance gardens, wet climates, tidy front gardens, and first-time growers

The drawbacks: with 451 ratings the evidence base is modest. Vinyl can become brittle after many years of strong ultraviolet exposure, which is the long-term failure mode. White vinyl shows soil splash and algae and will want an occasional wash. Eleven inches is adequate rather than deep. And vinyl walls flex more than steel or thick timber, so a very long run will bow outward unless it is braced.

Ones we did not include, and why

• Most of the first page of a keyword search. Galvanized steel bed kits from unfamiliar sellers, listings a few months old, ratings of 4.8 or 4.9 on a few dozen reviews. Some will be perfectly good. A raised bed is an object you install once and live with for a decade, and a new listing cannot tell you how the coating looks in year four.
• EAST OAK Galvanized 4 x 2 x 1 ft — 4.9 stars on 61 ratings. Attractive specification and far too small a sample to rank.
• Bed liners, fabric and covers. Several rank high in these search results and they are accessories. Useful — hardware cloth against burrowing animals is — but read the title.
• Anything described as a raised bed that is really a planter pot. A great many listings in this category are single containers under twenty gallons. They are fine products and they are not raised beds; check the stated cubic feet before you buy.

How to choose, in five questions

1. What is the bed sitting on?

Open soil: you can get away with ten to twelve inches, because roots go down past the frame if you loosen the ground first. Concrete, patio or decking: the walls are your total depth, so buy fifteen inches or more and buy it once.

2. What do you actually want to grow?

Salad and herbs: six to eight inches is enough, and an elevated bed is pleasant. General vegetables: ten to twelve. Carrots, parsnips, potatoes, big tomatoes: fifteen to eighteen. Buy for the deepest thing on your list.

3. Can you reach the middle from both sides?

Four feet maximum for a bed you can walk around, two feet for one against a wall. If you cannot reach the center, you will stand in it, and compacted soil defeats the entire purpose.

4. Is kneeling a problem, now or soon?

If yes, buy elevated, and accept shallower planting depth and more frequent watering as the price. A bed you can tend standing up is a bed that gets tended.

5. Have you priced the fill?

Work out the cubic feet before you buy the bed: length times width times depth, all in feet. Then price bagged soil against a bulk delivery, and plan the layered fill for anything deeper than a foot. This is the step that turns a disappointing project into a good one.

Setting it up so it works

• Site it for sun first, convenience second. Six to eight hours of direct sun is what most vegetables want, and no amount of good soil compensates for shade. Watch the spot across a day before you commit.
• But do consider the walk. A bed at the bottom of the garden gets visited less than a bed by the back door, and visiting is most of gardening.
• Level the ground before assembly. Five minutes with a spade and a spirit level prevents a bowed wall and a bed that drains to one corner.
• Loosen the soil underneath with a fork before filling, if the bed is on earth. This is what turns a twelve-inch bed into a deep one.
• Lay cardboard, not plastic, on the base. Cardboard smothers grass and weeds and then rots away; plastic stops drainage permanently.
• Add hardware cloth before filling if you have voles, gophers or moles. Retrofitting means emptying the bed.
• Overfill it. The contents will settle several inches in the first year as the lower layers break down. Mound it above the rim at the start.
• Mulch the surface. Two inches of straw, bark or compost cuts watering dramatically, and raised beds dry out faster than ground soil because they drain better and are exposed on all sides.
• Put the watering in on day one. A soaker hose or drip line laid before you plant costs very little and is the difference between a garden that survives August and one that does not. Our hose guide covers what to buy, and the key advice there applies here: buy the shortest hose that reaches.
• Top up with compost every spring. The bed sinks because the organic matter is doing its job. That is maintenance, not failure.

Frequently asked questions

How deep should a raised garden bed be?

Ten to twelve inches is the practical minimum for general vegetables, fifteen to eighteen for root crops and large plants, and six to eight is enough only for salad and herbs. If the bed sits on open soil and you loosen the ground beneath it, you effectively gain depth; on concrete or decking you do not.

How much soil do I need to fill a raised bed?

Multiply length by width by depth in feet to get cubic feet. A four-by-eight bed twelve inches deep needs about thirty-two cubic feet, which is roughly sixteen to twenty bags of bagged soil, or a little over one cubic yard delivered in bulk. Bulk is usually dramatically cheaper once you need a yard or more.

What is the cheapest way to fill a deep raised bed?

Layer it. Coarse woody material at the bottom, bulky organic matter such as leaves and straw in the middle, and six to eight inches of good compost and topsoil mix on top — which is the only part worth paying full price for. Expect it to settle and top it up annually.

Do metal raised beds get too hot for plants?

The sun-facing wall warms up and the soil near the edges dries faster, but the mass of soil in the middle moderates the effect considerably, and in practice it is manageable rather than a reason to avoid metal. Mulch the surface, water at the base, and in a cool climate the early-season warmth is an advantage.

Is pressure-treated wood safe for a vegetable bed?

Modern pressure-treated lumber uses copper-based preservatives rather than arsenic and is generally considered acceptable by extension services for vegetable beds. Older lumber treated with chromated copper arsenate, phased out of residential use around 2003, and anything treated with creosote — including railway sleepers — should not be used for food growing. If in doubt, line the inside walls with plastic sheeting and leave the base open.

How wide should a raised bed be?

No wider than four feet if you can walk around it, and no wider than two feet if it is against a wall. The rule is that you must be able to reach the middle without stepping on the soil, because compaction is the problem raised beds exist to solve.

Do I need to line the bottom of a raised bed?

Not with plastic — that blocks drainage and creates a waterlogged box. Cardboard is a good choice to smother grass, and it rots away. Hardware cloth is worth adding if you have burrowing animals, and it has to go in before you fill the bed.

How long do raised beds last?

Untreated pine, three to five years. Cedar, ten to fifteen or more depending on board thickness. Galvanized or coated steel, often twenty years or more provided the coating is not damaged. Vinyl, effectively indefinitely until ultraviolet exposure makes it brittle. Board thickness matters as much as species in wood.

Can I put a raised bed on a balcony?

Only with a clear idea of the load rating, because damp soil is around forty to fifty pounds per cubic foot and even a modest bed holds several hundred pounds when watered. For balconies, an elevated resin planter with a small soil volume is the appropriate product rather than a ground bed.

Our call

Plan the fill before you choose the bed, because the soil costs more than the frame and the layered approach saves most of it. Then buy for depth: the Land Guard galvanized two-pack is the sensible value choice at twelve inches, and the Vego Garden 17-inch modular bed is the one to get if you want root vegetables or the bed is going on a hard surface.

If kneeling is the barrier, the Yaheetech elevated boxes change gardening from an effort into a habit, and on a balcony the Keter Urban Bloomer is the right product rather than a compromise. And if you want a vegetable garden that looks like a garden, the Greenes cedar bed is the classic for a reason — just inspect the timber when it arrives.
