Designed with safety, versatility, and durability in mind, these boxes are built for athletes of all levels looking to improve power, coordination, and agility without risking injury from hard landings. Each box features a dense foam interior that provides firm support while minimizing joint impact—ideal for repetitive jump routines, box squats, step-ups, and other plyometric movements. The non-slip vinyl cover resists wear, cleans easily, and adds grip to keep your footing secure during high-intensity sessions. Whether you're recovering from injury, training for performance, or building a home gym from the ground up, this set provides the flexibility to adapt to your goals. Available in 4", 6", 12", and 20" heights, the boxes securely stack using heavy-duty Velcro flaps, allowing you to adjust the platform height quickly and safely—no shifting, no wobble. Use one box as a step or stack them all for progressive challenge. The soft edges make missed landings safer, reducing the risk of shin injuries compared to wood or metal plyo boxes. Space-saving, portable, and incredibly durable, this soft foam plyometric box set is a trusted choice for athletes, personal trainers, and everyday fitness enthusiasts. Whether you're training legs, core, or cardio, REP Fitness delivers the performance and protection you need to push forward with confidence.

  • Love these soft plyo boxes
Style: 4" and 20"
I purchased these about 1 week ago. I got these soft plyometric boxes for a few reasons: 1. These are much heavier than other ones. I've used another brand at the gym I go to and because they are so light, they are really wobbly when you jump on them. They feel like they are going to tip and they shake a lot when you land. Not a comforting feeling at all. These are super heavy! The big one I have (20") weighs around 75lbs. I got the gym I go to to swap them out with these, and they love them too. 2. I scrap my shins sometimes when I miss the jump. Problem solved! No more scraps or cuts. 3. I wanted something I could jump higher onto safely. We've stacked stuff on wooden plyo boxes at my gym, but I'm not a big fan. Wood on wood for stacking the plyo boxes gets slippery. I'll be back to add on more to the top. 4. Doesn't scratch the floor. I pair these up to do thrusters with, my pull up bar, and plyo box jumps! It came quickly, and the quality is great. I took a few pictures (attached) to show it. Cool contrasting stitching, strong handles. Be careful. I took a picture to show even with regular scissors I cut through the tape into the next layer of the box. A razor and stronger force could push through to the cover. Overall, super happy with these. Time to get to jumping, step ups, raised push ups, dips and more! ... show more

  • Sturdy
Style: 4", 6", and 24"
These plyo boxes are really sturdy, and I love the variety of jump heights the 24”, 6”, and 4” combo provides. My kids had outgrown their old flip-style box, which was a cheaper version. I'm so glad we upgraded—now they can do box jumps on the REP version without me needing to stabilize the boxes like before. ... show more

  • they are solid and work perfectly while stacked
Used for step jumping. Ordered 2 more, a total of 4, so that I can keep getting higher jumps in. They velcro together, have a wide platform and make it possible to have soft landings. They are individually very heavy which makes them very stable, if not a little bit difficult to stack. That''s why we work out though, so we can move these things. ... show more

  • Good but soft
Great weight and durability so far. Little too soft for my liking but easy to get used to and doesn’t impact use. Just takes a quick adjustment to make sure you don’t eat it.

  • They mean soft foam
Style: 4" and 6"
I've used similar stackable boxes at the gym, and this one is a bit softer than I recall those being. But it's advertised as soft foam, and it actually soft foam. Suits what I needed it for, and provides a nice unstable surface for balance training.
