Barbell 3-in-1 Foam Plyometric Jump Box – Adjustable Heights for Home Gym, HIIT, Step-Ups, Agility Drills & Strength Training

All in all this is an excellent plyometric box, especially for beginners. 1) Foam construction is very nice to prevent impact injuries. 2) Minor instability. The foam is not one solid piece. it is several layers of 4 inch thick foam. When placed in certain positions, there will be slight shifting when the layers are "stacked" vertically vice horizontally. However, it is not an issue as it just requires a more balanced landing, and can easily support a 200 pound jumper. 3) Picture shows some black granules that are inside, that can leak out of the zipper. It is not the foam which is white in color, and does not appear to be from the cover. There is not enough to add significant weight or stability to the box, so I am not quite sure why it is there. In any case, you can simply just vacuum it out or just clean it if it leaks out of the zipper opening.

Just like the professional ones at the gym. We use it all the time. Highly recommend this product. Excellent quality. Very durable.

Solid for being a foam box! I’m a big guy and it easily handles my box jumps. Multipurpose and easy to manipulate. Surprisingly light weight. Perfect addition to my home gym!

Good, but not great. Not stable for jumping, but good for step ups.

I don't normally write reviews or things, but for this I'll make an exception. Someone thought it would be a good idea to put multiple foam slides in an enclosure and call it a box. You can imagine what happens if you turn that box in any way..... Let's just say it almost blew up my ACL. The sturdiness is awful and no one should be buying this

This is a perfect addition for our at home gym. My 9 and 11 year old can easily lift this piece of equipment to do the workout needed. Worth the price I paid.

Awesome, durable, lightweight, perfect for what we need it for

My daughter in law uses it to very day.

Sturdy and well made while being light to move around d.

Got this in time for Christmas. Works well and was a great price.

Does exactly what it's supposed to do. Sturdily built.

Garbage. Uneven surface. After 2 days use the hard foam pieces unglued and now make the box very unstable. There are also black beads inside that move around which is annoying but also make a mess everywhere. I'm thinking they added this for additional weight.

Très instable. Ce n'est pas sécuritaire pour les niveaux 24 pouces et 30 pouces. N'achetez pas ce produit. De plus, amazon exige des frais pour le retour
