Three heights in one box, and edges that decide the shin
A plyo box is jumped onto, which makes it the one item on this shelf where a failure is an injury rather than a disappointment. The standard article is a three-in-one: a rectangular box that gives three heights depending on which face it rests on, commonly 50/60/75 cm or 40/50/60 cm. The heights are published and they are the specification. The second figure is the load rating, and it should be read as a dynamic figure — a person landing on a box loads it with several times their body weight for an instant, and a rating quoted without saying whether it is static or dynamic is quoting the easier number. Then the material, which splits the shelf cleanly. Wood boxes are the traditional article: rigid, heavy, and unforgiving of a missed jump. Foam boxes with a vinyl cover cost more, weigh less, and are the ones that do not open a shin when a jump falls short — which is the failure mode that actually happens. Steel boxes exist and are usually fixed-height. The top surface needs grip, and the good ones state a non-slip treatment rather than showing a photograph of one. Edge treatment — a chamfer or a radius on a wooden box, a soft edge on a foam one — is the detail that separates a box designed for jumping from a box designed for a photograph. And assembly: most wooden boxes arrive flat and need bolting, and the quality of that hardware is what the review has to look at. We compare heights, top surface, material, load rating and load basis.
458 mm, steel trapezoid, silicone top, rubber feet
The only steel box in this family — a welded trapezoid at 458 mm with a textured silicone top and four rubber feet, rather than a wooden cube.
Best for: A single working height where the base needs to be wider than the top
61 × 51 × 76 cm, 24 kg, 200 kg, pine and poplar
The only box in this family to publish its own mass — 24 kg — and the only one to name both timbers: pine outside, poplar inside.
Best for: Somebody who wants the timbers named and the box to stay where it is put
30.5 / 35.5 / 40.5 cm, solid beech, 2 cm panel, 120 kg
A solid beech box that publishes its panel thickness — 2 cm — alongside three heights and a 120 kg rating, with interlocking joints.
Best for: A first box at a modest height where the timber is worth knowing
Two variants, 16/20/24 or 20/24/30 inch, 300 kg
The highest published rating in this family at 300 kg, in a wooden box offered in two three-height variants covering 16 to 30 inches.
Best for: Somebody who wants a specific height band and the highest rating available
75 × 60 × 50 cm, three heights, no load rating
A three-height box at 75 × 60 × 50 cm, with rounded edges and a non-slip coating — and no load rating published.
Best for: Somebody who has outgrown a 40 cm box
51 × 48 × 41 cm, multi-layer, puzzle joints, 120 kg
A multi-layer box with puzzle joints and a corner-free design, published at 51 × 48 × 41 cm — three heights from one block.
Best for: Somebody who wants the edges rounded before the first missed jump
40.6 / 35.5 / 30.4 cm, plywood, 204 kg, honeycomb top
A plywood box rated at 204 kg — the second highest here — with a honeycomb surface texture and pre-drilled holes for assembly.
Best for: A heavier user who needs a rating well above the entry boxes
40 / 50 / 60 cm, wood with EVA foam cover
The only soft box here: wood under an EVA foam cover, with the height printed on each face — the one construction that forgives a missed jump.
Best for: Anybody who is going to miss a jump and would rather meet foam than plywood
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
