Three heights in one box, and edges that decide the shin · review
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.
The bottom line The only steel box here, and the shape is the point: a welded trapezoid puts a wider base on the floor than the surface a foot lands on. The silicone top and rubber feet are named rather than described. It publishes no load rating at all — one of three boxes in this family that do not — and offers one height where the rest offer three.
A trapezoid, not a cube.
Every other box in this family is a rectangular block with the same footprint top and bottom. This one is wider at the base than at the top, which is what resists tipping when a landing lands short or off-centre.
It is the clearest structural distinction in the family and the maker states it directly.
Steel does not splinter and does not compress.
A shin meeting a welded steel edge takes a harder impact than one meeting plywood, and considerably harder than one meeting the foam-covered box elsewhere in this family. That is a property of the material rather than a fault in the product, and it is worth stating plainly.
No rating at all.
Five of the eight boxes here publish one, from 120 kg to 300 kg. This one publishes nothing, and the absence is recorded rather than filled from the material.
Not one box in this family states whether its rating is static or dynamic — a mass at rest or a mass arriving.
On a product whose entire purpose is to receive a jumping body, that is the question, and eight makers out of eight leave it open.

The American Amazon store carries it too, priced in local currency — which the euro range above leaves out on purpose.

The base is wider than the top, so the box resists tipping when a landing is off-centre. A cube has the same footprint top and bottom; a trapezoid puts more contact on the floor than under the feet. The maker states the shape is what gives the structure its stability.
No figure is published. Five of the eight boxes in this family publish a load rating and this one publishes none, which this page records as an absence rather than inferring one from the steel.
It fails differently rather than being better. Steel does not splinter and does not absorb; a shin meeting a welded steel edge is a harder impact than one meeting plywood, and softer still than either is the foam-covered box elsewhere in this family.
A single working height where the base needs to be wider than the top
