One foam block, three jump heights, and a padded edge where a wooden box would have a corner.
The 3-in-1 Foam Plyo Box is the foam version of the standard wooden 3-in-1 box: a solid foam block wrapped in a durable vinyl cover, with three usable heights depending on which side faces up. The smaller box gives 16, 20, and 24 inches at 39 lb and $225. The larger gives 20, 24, and 30 inches at 55 lb and $350. Heights are marked on the cover so you can confirm the setting at a glance.
The case for foam over wood is simple: a missed jump meets a padded vinyl edge instead of a plywood corner. Power Systems positions the foam construction as minimizing injury risk from contact with the box, and that is the practical difference you feel when training jumps near your limit or coaching someone new to box work. For step-ups, box squats, and elevated push-up positions, the firm block is stable under load.
The trade-offs are weight and price. Flipping a 55 lb block between heights is a two-hand job, and the foam box costs more than a comparable plywood box you could build or buy. Vinyl covers on any foam plyo box also show wear at the edges over years of rubber soles landing on them, so this is gear you buy for the training quality, not for resale. One block also takes real floor space: this is a garage gym purchase, not an apartment one.
For a home setup, the smaller 16x20x24 box covers most people. The 20x24x30 makes sense if you already jump 24 inches comfortably and want headroom.
Garage gym owners adding jump and step-up work who want a forgiving landing edge instead of plywood.
You are tight on floor space, or a basic wooden box at a lower price covers your step-up needs.

The 16 by 20 by 24 inch box weighs 39 pounds and the 20 by 24 by 30 inch box weighs 55 pounds, according to Power Systems. That is heavy enough to stay put during jumps but still movable by one person. The smaller box ships in a 24.25 by 16.25 by 20.5 inch carton.
is a foam plyo box better than a wooden plyo box
The difference is the surface.

Pick by the height you already jump. The 16 by 20 by 24 inch model covers most general fitness and group training and weighs 39 pounds. The 20 by 24 by 30 inch model tops out at 30 inches for athletes already clearing 24 inches, and weighs 55 pounds. Both give three heights from one box.
