Retrospec Leap Plyo Box Jump Platforms for Home Gym Plyometric Jumping, Strength Training & Jump Box Exercise, 12", 18", 24", 30" and Full Set for Men and Women

Great quality, very sturdy and strong!

Just what I wanted! I love doing so many exercises besides just Plyo jumps!! . It is sturdy, well build and great size. It came assembled which is a bonus.

These are high quality and well built.

I looked at lots of Plyo Boxes before settling on this 18" version. I was using a 14" platform and decided I needed to bump it up. This height gives me that thigh-to-floor parallel for step-ups. I don't jump - my knees say no - but I wouldn't be afraid to because of the sturdiness of this box. I've never once felt like it might tip over. It came assembled with every square inch covered in protective wrap... no dings, dents or scratches. It's squared and sturdy. The angle of the legs and base provide terrific stability without interfering in my footwork. The platform is wood with a firm rubber top to provide traction and soften the impact. The platform is very well braced underneath so no worries of it failing. The box is lightweight and easy to move around. Great purchase!

No assembly- solid welds - substantial weight - skid resistant top - no smell - no marks on floor

I'm not using these as jump boxes. They're serving a wide variety of other purposes from assisting with other exercises to being used as stools while painting to the 12-in being used as a step stool. And I'm happy with them for these purposes.Not sure if I would be having paid full price though as I got a used set for more than 50% off. To my surprise, the reported damage was minor tearing of the top material. A bit of gorilla tape fixed them right up to prevent further damage, and I might either replace the tops with thicker plywood or cover them with proper rubber-like padding in the future anyway. So totally worth it for the savings.They seem quite sturdy. The 30-in one squeaks and creaks quite a bit, but I think it'll hold up fine. Probably just from having longer legs. The others seem quiet and firm. No stability issues that I've seen.

Love the sturdiness of this jump box. Don't love the material on the top. It tears easily.

The most important thing to me is that I have confidence that it won't tip over, and slip out from under me. It's welded and stable, it doesn't creak or rattle. I have confidence using it.I'm not sure how long to vinyl cover on the top will last, but if it gets worn, it looks like it will be easy to replace.The rubber feet are important to me. I plane to use this on a hard floor, and I need to to stay still.I would easily recommend this.
