JFIT Plyometric Boxes - Made in Taiwan NO Assembly Required Single - Height Box Set and Adjustable Box Options Plyometric Platform and Jumping Agility Box for Training Conditioning Strength Training

Why did you pick this product vs others?:This item has withstood months of me standing on it and jumping to exercise plyometrically and think the highest two boxes are too high for anyone to use but those make great plant holders and side tables. I really like the design.

Prices vary throughout the year but if you keep an eye out for sales this can be a very good deal. Very firm and stable, useful for a lot of single leg exercises.

the box is rugged as hell, i use it a lot

Sturdy. Love it.

We bought these in 2018 for our autistic son to have things to jump on and from other than our furniture. He graciously accepted our offering and proceeded to include the boxes in his living room parkour. We are on our second sofa and one of our chairs is pretty beaten up, but these boxes are fine.He is not jumping onto them from the floor, but he pushes them around into different configurations and jumps from one to another, or back and forth from them to furniture. My other kids have jumped around on them, although not nearly as much as he has. They also have been stand-ins for a step stool for me when I want to reach something up higher than I can reach.Now he has only been 40 - 55 pounds during the time we've had them, and my other kids are all 110 pounds or less, but I've been over 200 pounds this entire time and they have held up to all the abuse we've heaped on them. They were definitely worth the $200 we spent on them, but I'm not sure if I'd replace them for $300 if something happened to them. They do take up a bit of space, especially if they are not nested.

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.

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.
