A raised bed planter with legs lifts the soil box to about 20 in to 32 in off the ground, so you can garden without bending and still fit a bed on a balcony or patio. Our research found three different builds: a 38.5 x 13 x 31 in metal frame with a fabric box and wheels, a 36 x 12 x 32 in galvanized steel bed with a stated 21.8 gallon capacity, and a 29.6 x 14.5 x 19.7 in plastic bed with a stated 10 gallon capacity. The three numbers to check are soil volume, the load the listing states, and whether the footprint leaves a walkway.

Why choose a raised bed on legs
A ground-level raised bed needs a yard. A bed on legs needs only a floor, which is why it suits a balcony, a patio corner or a driveway edge. The legs also keep the soil box off wet pavement, so water drains out of the bottom instead of pooling around the base.
The height is the second benefit. A 19.7 in bed is lower and suits sitting on a stool or a child’s reach.
The trade-off is soil depth. Legs take height that a deep bed would otherwise use. The beds in this guide hold soil about 9 in deep or less, which is enough for lettuce, herbs, radishes and strawberries, but shallow for carrots or tomatoes.
Three raised beds with legs from the research
These three show the range of materials and sizes. Each is a single bed; none is a large garden.
The 38.5 in metal frame with a fabric box and wheels
The Fiwithy bed lists as 38.5 x 13 x 31 in and describes a powder-coated metal square tube frame with a waterproof fabric box. The listing says the box is 31 in long, 13 in wide and 9 in deep and has three drainage holes. It has two large wheels and a handle, so you tilt it like a wheelbarrow to move it toward the sun. The spec table states a 400 lb capacity.
A fabric box is light and breathes, but it is not as stiff as a metal or plastic box. The size also reads two ways, because the outside is 38.5 in long and the box inside is 31 in. Use the 31 in figure for planting space.
The 36 in galvanized steel bed
The Land Guard listing is for a 2-pack of 36 x 12 x 32 in beds, so the dimensions describe one bed and you receive two. The listing states heavy-duty galvanized steel with an anti-rust coating, a 21.8 gallon planting capacity and a 300 lb capacity, with two wheels and a handle. The listing says it is made to fit narrow spaces like balcony corners.
The 12 in width is the key number. It fits along a railing and leaves the rest of the floor clear. The weight listed is 14.47 kg, but with a 2-pack it is unclear whether this is per bed or for both, so do not use it to plan a lift.
The 29.6 in plastic bed
The BIVODA bed lists as 14.5 x 29.6 x 19.7 in and is made of high density polyethylene (HDPE). The listing states 10 gallons of planting space, a 250 lb weight capacity, drainage holes and assembly with pre-inserted nuts and stainless screws. The listing says the plastic will not rust, rot or splinter, and that it can be cleaned with soap and water. The bullets give slightly different dimensions of 29.9 x 14.2 x 19.7 in. Treat the length as about 30 in.
It is the shortest and has no wheels, so it is the choice for a fixed spot, such as the end of a bench, or a lower bed for a seated gardener.
How to choose
Soil volume
Convert the stated volume into something practical. One US gallon is 231 cubic inches, so 21.8 gal is about 5,036 cubic inches, which is 2.9 cubic feet. The 10 gal bed is about 1.3 cubic feet. For the fabric bed, 31 x 13 x 9 in is 3,627 cubic inches, or about 2.1 cubic feet. That is the real size of the garden you will fill, so use these numbers when you buy soil.
Load and soil weight
Wet potting mix is heavy. Multiply by the volume: 2.9 cubic feet is about 116 lb, 2.1 cubic feet is about 84 lb, and 1.3 cubic feet is about 54 lb. Add the plants and the watering, then leave a margin under the stated load. All three examples sit well below their stated 300 lb, 400 lb and 250 lb limits.
Material
Galvanized steel is stiff and reasonably rust resistant, but a scratch can start rust, so touch up chips. A fabric box is the lightest and drains freely, but it may bulge when full and can wear out sooner at the seams. HDPE plastic does not rust, but a pale or thin plastic can fade in strong sun.
Wheels
Wheels help if you want to chase sun or tuck the bed away for winter. But wheels on a full bed mean the legs and frame take side loads. Move the bed only when the soil is not saturated, and use the handle as the listing describes.
Worked example: two beds on an 8 ft by 4 ft balcony
A balcony is 96 in long and 48 in deep. You want two of the 36 x 12 in beds along the back wall.
- Wall used. 2 x 36 in = 72 in, so 96 – 72 = 24 in of the wall stays free, enough for a chair or a hose reel.
- Floor taken. Each bed is 36 x 12 = 432 sq in, so two take 864 sq in, which is 6 sq ft.
- Share of the balcony. The balcony is 96 x 48 = 4,608 sq in, which is 32 sq ft. 6 / 32 is about 19 percent.
- Walking width. 48 – 12 = 36 in in front of the beds. This matches the 36 in that the US Access Board gives as the minimum clear width of an accessible route, which we use only as a planning yardstick.
- Soil. 2 x 2.9 cubic feet is 5.8 cubic feet, about 232 lb at our 40 lb estimate. Per bed that is about 116 lb, well under the 300 lb stated.
- Harvest. A 32 in tall bed puts the soil surface about 32 in off the floor, which is a comfortable standing reach without bending.
The result is two usable beds on one wall and a path wide enough to walk. Check the balcony’s own load rating with your building manager if you plan to stack several beds, since a full set of beds can add several hundred pounds.
What to grow in a shallow raised bed
With soil about 9 in deep, pick shallow-rooted crops. Lettuce, spinach, arugula, radishes, scallions and most herbs such as basil, parsley, chives and mint all do well. Strawberries stay compact enough for a 12 in wide bed. A single determinate tomato plant is difficult in 9 in of soil, so grow it in a larger pot nearby.
Mint spreads aggressively, so give it its own bed or a pot inside the bed. Put taller plants at the back and trailing ones near the edge. If you want a flower row, add a few trailing varieties on the wall side.
Watering and drainage
A bed on legs dries out faster than one on the ground, because air flows under it and the soil is not connected to the earth. Water when the top inch is dry, and check again in hot weather. Drainage holes matter: a full 10 to 20 gallon box with no holes becomes waterlogged in a heavy rain.
Place a tray or mat under the bed on a wooden deck or a balcony. Water that runs out can stain wood and may drip onto a neighbor below. A shallow tray under a narrow bed catches most of it.
Who should buy a raised bed planter with legs
- Balcony and patio gardeners who have no ground to dig.
- Anyone with a bad back or knees who wants to garden standing up.
- Renters who want a movable bed that leaves no mark.
Who should skip it
- Gardeners who want deep-rooted crops. The soil here is too shallow for carrots, parsnips or full-size tomatoes.
- Owners of weak balconies. If you do not know the floor’s load limit, start with the lightest bed and fewer plants.
Common mistakes to avoid
- Counting the outside length as planting space. The fabric bed is 38.5 in long overall but its box is 31 in.
- Filling with garden soil. Heavy garden soil compacts in a box. Use a light potting mix.
- Forgetting the weight when moving. Do not lift a full bed. Tilt it on its wheels or empty it first.

Frequently asked questions
How deep should a raised bed planter with legs be?
For salad greens and herbs, 6 in to 9 in is enough. For root vegetables you want 12 in or more, which most legged beds do not give. The Fiwithy listing gives a box depth of 9 in, and the others do not state a depth, so check the listing before you buy.
Can I use a raised bed planter with legs on a balcony?
Yes, if the balcony can take the weight. A full bed holds about 54 lb to 116 lb of wet soil in our estimates, plus the bed itself. Ask your building manager if you are unsure, and spread the load across the legs.
Do raised beds with legs need drainage holes?
Yes. The Fiwithy bed lists three drainage holes and the BIVODA bed lists small holes in the base. Without drainage the soil stays wet and roots rot.
Will a metal raised bed rust?
Galvanized and powder-coated steel resist rust, but scratches expose bare metal. Touch up chips and keep the feet dry. The BIVODA plastic bed is listed as rust-proof.
How much soil does a 36 x 12 in bed need?
The listing states 21.8 gallons, which is about 2.9 cubic feet. Buy slightly more than that, since soil settles after the first watering.
