Super high quality!
Style: 6" and 12"
These are incredibly great quality. They are super heavy duty and sturdy. They are quite heavy as well. We use these almost every for everything…as actual plyo boxes but also as a bench for light exercise. These are just awesome!

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

Solid pylo box. Would definitely recommend.
Style: 4" and 20"
Great polo box. My entire family has done box jumps on it. Expensive but definitely worth it. Bought the 20 inch and 4 inch to increase size. Stable, heavy, solid built like a tank.

I would recommend this product.
Style: 4", 6", and 20"
I had cheap plyo boxes with mutiple sides and sizes. They were not sturdy at the highest point when jumping. This is a lot safer for my kids In my home gym. Theae plyo boxes are sturdy and heavy duty.

Good but soft
Style: 6", 12", 20"
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 are solid and work perfectly while stacked
Style: 6" and 12"
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
