Rank #7 in Best Plyo Box 2026: 10 Ranked, and the Spec Sheets That Argue With Themselves
RIP X Soft 3 Sided Plyo Squat Jump Box, 12/16/18 in
Price and rating as shown on Amazon when we collected them. Both change.
The RIP X Soft 3 Sided Plyo Squat Jump Box sits at number seven in this guide at £34.99 — less than the £54.03 and £68.00 boxes named elsewhere in it. It is a foam box rather than a wooden crate: the listing describes a non-slip cover over high-density foam and says the soft surface is "much safer and also lower impact than traditional solid boxes and crates with hard edges". It carries 4.3 out of 5 from 83 Amazon customer ratings, and 69 of those 83 are five-star.
The listing does not quite agree with itself. The name says "Boxes", plural, and "3 Sided", while the specification table underneath says "Number of items: 1" — the three sides are three heights (12 in, 16 in and 18 in), not three separate boxes. The bullet gives a weight of 1.7 kg; the Package Dimensions line gives 2.6 kg, and the listing does not break down where the extra weight sits. A foam plyo box also carries the field "Guaranteed software updates until: unknown". Everything on this page is taken from the Amazon listing as it appears, not from any testing of our own.
