Our stand-out pick

Forest Caledonian Corner Raised Bed 4' x 4'

The Forest Caledonian Corner Raised Bed 4' x 4' is our pick on paper. At £84.99 it offers a 28 cm planting depth and a capacity of up to 500 L, plus a 15-year anti-rot warranty. Its corner shape also suits gardens where a straight bed would waste space. This choice comes from comparing the listed details, not from testing.

Five raised beds compared

01 · Best Budget Starter Bed

Forest Caledonian Small Raised Bed 3' x 3'

A low, simple 3' x 3' bed that suits shallow-rooted crops and flowers at the lowest price here.

The Forest Caledonian Small Raised Bed costs £29.99 and is the cheapest option in this roundup. It measures 90 x 90 cm and stands just 14 cm high, so it is a shallow growing bed. The listing recommends it for shallow-rooted crops and flowers. The timber is 40 mm FSC-certified and pressure treated, with half-lap joints. Assembly is self-assembly and needs only 4 screws. A 15-year anti-rot warranty is included.

02 · Best for Layered Planting

Forest Caledonian Tiered Raised Bed 3' x 3'

A three-tier bed that packs several planting levels into a 3' x 3' footprint.

The Forest Caledonian Tiered Raised Bed costs £133.99 and takes a different approach from the flat beds. It has three tiers, so you can spread herbs, flowers or vegetables across different heights. It measures 90 x 90 x 56 cm, and the pressure-treated timber has a green tint. Assembly is self-assembly, with an estimated time of 2 hours. It carries a 15-year anti-rot warranty. It costs £48.99 more than the 4' x 4' Corner Bed.

04 · Best Long, Narrow Bed

Forest Caledonian Trough Raised Bed 6' x 1'6"

A 1.8 m trough with a slim footprint, aimed at flowers and herbs along a boundary.

The Forest Caledonian Trough Raised Bed costs £141.99 and has a long, narrow shape. It is 180 cm long, 45 cm deep and 14 cm high. That suits a strip beside a fence, wall or path. The listing recommends flowers and herbs. The timber is pressure treated, with half-lap ends. Assembly is self-assembly, and it comes with a 15-year anti-rot warranty. At £141.99, it costs more than the Corner Bed, which has a far larger listed capacity.

05 · Best for Deeper Growing

Zest Deep Root Planter 1.8m

The deepest and tallest planter here, with 38 cm of growing depth and up to 500 L capacity.

At £169.99, the Zest Deep Root Planter 1.8m is the priciest option here and works more like a raised bed than a patio pot. It measures 180 x 70 x 80 cm, offers a 38 cm growing depth and holds up to 500 L. It is made from pressure-treated wood. It weighs 41.5 kg, which is lighter than the Tiered, Corner and Trough beds but far heavier than the 9.2 kg Small Raised Bed. It is self-assembly, and a liner is not included. Cover is a 12-month parts warranty.

Price snapshot: £169.99 at One Garden, recorded 2026-11-02. Check the retailer page for the current price.
