Assembly wasn't as easy as I would have thought. A couple hard to reach places. But just bust out your ratchet and you'll be good to go.Anyway, just started jumping on the 30" one yesterday and man, my ABS are sore. Great workout.We'll see how stable they are after a few months of use but so far, I love these things,

Product was easy to assemble. Well built and sturdy. Would recommend to anyone. Edward Collins.

All in all does exactly what we needed for the home gym. The only negative is you have to unstack them to get the smaller ones out of the bottom instead of being able to slide out of the stack.. not a big deal though

The jump box was easy to assemble and it's extremely sturdy. I weigh 235 pounds and it supports my weight with no issues. The anti-skid rubber surface also gives me added reassurance that I won't slip off the box when using it. And the open space inside the box frame provides a great space for storing free weights and other gym equipment in my home gym. Overall, I give this product an A+! --Drew Stewart

Easy to move around and perfect height for a variety of workout needs

Solid. No issues with jumping up onto the box or stepping up for pull ups. Sturdy and good quality.

Love the bench! However, missing one bolt (received the screw), so one corner is not secure.

I would definitely give it a 5 but, it has so many metal finished imperfections, painting and one very important a sharp metal sticking out on one of the bottom support, other wise is good stand. I had ordered a smaller one before and it was 100%. It seems this one was rushed.

I'm only 5'3 so I wish I'd gotten a slightly shorter box for my short legs but it's sturdy and a good value for the price. Simple assembly even with my 4 year old "helping".

Pretty expensive for a basic stool, but it is high-quality
