We are very pleased with our new adjustable plyometric platform. We have it set to 16 inches, which is a good challenge and leavies 20 inches as a future goal. We love how the platform is very sturdy and stable without being heavy and awkward to move. The aparatus for adjusting is very simple and secure. We had been debating between this platform and one of the "stuffed" cubes. This platform is a better option for portability and stability; highly recommend.

My JFIT Box is absolutely perfect. It's sturdy, well constructed, beautiful and I know it will last forever. I plan on using it for exercise but I can also see it doubling as step stool whenever i need to an extra 12' taller. Well done JFIT. I am a happy customer.

I'm not expecting a gym-quality piece for stadium climbs or massive free weights. Just a solid device for safe concentric and eccentric leg development at home. This will do very nicely, even if I fail to keep the cat's claws off the vinyl top covering!Good welds and powder coat on the steel frame, with thumbscrew sets for the typical rod-and-hole style height adjustment. The plastic feet are lightly glued onto the square metal legs, so they'll need to be better secured if moving around much is expected. The lowest actual height on this 12-16-20 adjustable version is 11 3/4 inches, and the higher positions are similarly short of nominal. Not a problem for me at all, since the whole thing rests flat, level, and quiet -- even on a ceramic tile floor. That's especially important to me, since I 'll be focusing on the step-down part even more than the opposite motion! Finally, I don't forsee any construction issues if I use this with 25 lb dumbbells, as planned.

I purchased the J/Fit adjustable PLYO box (12"/16"/20") and it is perfect for my workout room at home. I can do one-legged lift ups and bulgarian squats among many other excercises. It doesn't take up much space. It came assembled at 12" height and is easy to adjust and very stable. Highly recommed this product.

Returning as it arrived damaged. I don’t think it’s safe for exercise use anymore. Not sure how that corner is so bent because the box looks very sturdy, the packaging that it arrived in wasn’t damaged. Maybe it was like that from factory.Also £120 for delivery is a scam! I didn’t realise until I received it.

Muy buena calidad y buen tamaño para lo que yo buscaba.Esta excelente para hacer ejercicios de pierna porque esta un poco mas elevado que un step normal pero no tan elevado que haga muy difíciles los ejercicios.Ocupa poco espacio en casa y es una buena pieza de mi equipo de gym en casa.

Received this product earlier than expected, kudos to that. Sturdy, does it's job. Got the adjustable height 18, 24, and 30 in. Got it on Fri 12/10/21. Using it for box squats, box jumps, and box step ups. So far been using the standard 18 in. height out of the box. Best tool for practicing box goblet squats, or any clean or overhead exercises to practice using core muscles and developing core strength. Haven't tested the adjustable heights yet, but for now it does its job. I like the width of the step up. I believe it's 16x16in. so enough space for box jumping and step ups. I shall probably do a post review later once a play with the adjustable height. Other than that it serves it's purpose. Hopefully this review will help customers on their purchase. I'll make it easier, as senator Palpatine says,"dew it!" Lol

I bought two sizes for my son's football training and was amazed at how sturdy they are. They appear to be very well built from the top to the frames. And, that they fit within one another is incredible, too. A nice design. These would even work for light "step" workouts or standing on for small household chores or even painting a wall, or even sit down gardening depending on the height and the size you buy! A very good buy, but a little bit pricey. I would have bought the whole set if the price was a bit lower, so I had to limit us to just two. Otherwise, a great item, packaged well, and delivered quickly.

I love it! I haven't been using it but you can use it as a chair or sometimes when you need to reach for something. You can used it for a lot of things - including Plyometrics :)
