Stamina X 12" to 24" Adjustable Height Plyo Step Up Exercise Box For Home Workout with Access to Muuv, Non-Slip Surface and Workout Guide, Black/Red

Very sturdy and adjusts well. My junior high athlete uses this at its highest setting often. I don't have any concerns about it collapsing. It is a bit heavy. However, it seems like a solid build.

I just bought this and used it a few time but so far it's great. The quality really is fantastic and I don't think I'll ever have to buy another Plyo box. The paint quality is good, I didn't have any scratches/nicks/ or missed spots on mine. So far I've used this box for jumps-great, doesn't move/slip, and the rubber top surface has some cushion, and isn't slippery, elevated push-ups, stretching, etc-pretty good, the sides don't have any sharp surfaces so you won't cut yourself. Only possible complaint here is there isn't a lot of room to grab on the sides because of the sliding mechanism for the legs...not really a big problem just wanted to let others know. I also was doing some plumbing in the basement and just need to be up a step or two...this is way better then a ladder because you can walk around a bit so I wasn't constantly moving a ladder. Overall I'm very happy with this and would recommend it to anyone looking for a high quality adjustable Plyo box. The legs aren't hard to adjust but take a little getting used to. I wouldn't want to do a workout and change the height a bunch of times throughout the workout, so the only possible way I wouldn't buy this is if I was doing a workout that needed multiple Plyo box heights in each session, then I'd probably buy a dedicated height set. I was going to build my own multiple height wooden box and am very happy I decided against doing that.

After researching several plyo boxes, I eventually decided to give this model a try. The price was higher than I was initially planning to spend, but the ability to have four heights made it more cost effective than potentially buying four fixed height boxes. I also considered building my own plyo box or using a 4-in-1 kit box sold on here. My concern with the wooden box was the stability on the higher heights. When the Stamina box arrived, I was surprised at how sturdy and stable it is. Plenty of room on the top platform and solidly built. My son told me that this is nicer than the fixed height boxes they use in the high school weight room. The height adjustment took a bit to get used to, but once I found the leverage point it's pretty easy. Overall I'm very pleased with this purchase and would recommend this to other family or friends.

YES, as we can see from all the other reviews, everybody loves it! I should be exercising on it right now but instead, I can't resist sharing a few other ideas I've had that have not yet been mentioned by anyone else. This thing might just become one of my best Amazon purchases of all time since I'm already thinking of so many other ways it could be used around the house. Thinking about it as gym equipment. First, just moving it around is exercise for me. Secondly, it's amazing to me that even Stamina Products Inc hasn't thought to mention that it can be set at various angles making it useful as a workout bench for presses, curls, even what I'd call, old man sit-ups! Have no worries about adjusting it, just as long as you lay it on it's side first. Another use that occurred to me when I saw it at a temporary markdown price of $160 was as a pet grooming table which, for my hundred pound German Shepherd Dog, it's just perfect! Other ideas I've had for around the house use would be for an adjustable height table/TV stand. In the wood/metal shop as a machine stand or Workmate® type table. I'm a photographer and I plan on using it as an adjustable height stand in my photo studio for product or model photography. Hell, I can even think of creative ways it could be used in the bedroom but I'd better leave that up to y'all's imagination. Yes, like so many things these days, it's made in China... it's even painted red but otherwise, I didn't see any problems with that. I like it so much, I'm half tempted to put some auto pin striping decals on it! All in all, I think it's so great that we have AMAZON to show us all items like this which, without them, I for one, would never have known even existed.

High Quality. Made to last

A very sturdy item well made and heavy. The height adjustability is nice but it's difficult to adjust the height. I find I have to turn it on its side to to get the proper height as both sides have to be the same but they move independent of each other.

I love this plyo box. VERY sturdy!! I'm a 225lb male and I use this for box jumps, weighted step-ups, and as a depth measure for heavy barbell squats. It is used in my garage on a concrete floor. It doesn't slide at all when I hop on it. Again, really sturdy - no give at all. I use this box for one thing or another in almost every workout. I wasn't expecting to do that. But it's just so useful. I was worried about buying it based on the reviews about that thin metal bar that keeps the bench height locked. Yes, it is thin metal but it doesn't support any weight and is absolutely ample thickness for the job it does. Don't let these reviews sway you. The person who bent theirs... well, I don't know how that could happen (special I guess). FYI, the easiest way to change height is to put the plyo box on it's back (so the adjustment bar is facing up). It's pretty simple.

Heavy. Strong construction. Nothing to put together. Commercial grade strength.

This thing is a tank very well built.

I got this plyo box in the morning and incorporated it into my leg workout the same evening. After doing deadlifts, I did step ups and bulgarian split squats to supplement that leg work and found the plyo box to be super stable. I had no trouble figuring out how to adjust the height of it and am very happy with the quality overall. Time will tell, but it feels so sturdy handling the force that I exert on it, that I am confident that it will last for a long time. I can't wait to move into the power phase of my year and do the exercises that it is made to endure. Please comment to ask me to give an update on how it is holding up, if you would like to know.

This Plyo Box is really impressive. It's sturdy, stable and the height is easy to adjust. My wife and I have been using it everyday for the past month and I have no complaints. You get a great product for your money that will last you for a long time.

Heavy steal (able to handle a lot of abuse), well built (stable at any height), and covered with a thick coat of quality oil-based paint (will not rust easily). Will last forever = worth every penny!

Extremely good workout tool; it's sturdy and reliable; at 40 pounds, it is stable and offers a firm anchorage. I use it regularly and it does not require a lot of time to make the transition between heights. 200$ for a 4 in 1 plyo box ? it is a bargain, given the quality of the product.
