VEVOR Knæstol Ergonomisk 250lbs Belastningsbærende kontorstol Knæstøttestol Knælende kontorstol Justerbar knæstol til kontor- eller hjemmevinklet knæstol

I bought this as my pelvis had tilted over the years with normal office chairs and within the first 10 days I noticed a remarkable difference in my posture. It makes you sit bolt up right and does not put pressure on my knees even though you are in a knelling position. I would highly recommend this item.

Fantastic product. If I get back pain it’s because I haven’t been using this chair, and when I do use it the pain clears up.

Comfy, really improved my neck and should pain. Stylish.

Puts your posture in the right position to stop your pain both in your back and reflected into your legs.

Very pleased with this chair. I’ve had back problems for years and can’t stand for too long or sit in a normal office chair. Not only do I use it as a computer chair but also when doing the ironing! Amazing value too. So glad I bought it! ☺️

Once put together. Does the job.

After a few weeks I'm almost totally used to this chair and no longer use my old one. It has helped with my posture and back pain. I will probably replace the wheels as they are a bit cheap, but amazon sells nicer ones.

This is a good product except for one flaw: the foam used on the seat is very thin which makes sitting for a long time uncomfortable. I replaced the foam on my chair and it is now much better.

Really comfortable and cozy. Delivery was fast. Easy to assemble. Since I started using it, I've stopped having back and leg pain caused by sitting for hours working on my laptop.

My review is for the black adjustable version of this chair. I have been using this chair for over 1 month now and I am quiet pleased with it. In fact, this chair has become the main chair at my desk and considering I have a "desk job", I suppose that says a lot. Just want to mention that I am a rather short person, 161cm, and that was the reason I chose the adjustable chair. That was certainly the right choice for me, as I could adjust it to my size and whatever position feels best to me. My husband happened to buy the other non-adjustable wooden version of this chair, so I had a chance to compare them. Indeed, the non-adjustable wooden chair felt too large for me, I kind of felt like a kid sitting on the edge of the chair, also the material on that one is a little bit slippery for my liking. Both chairs were fairly easy to assemble, I had no problem with that. The only maybe negative about this chair so far is I am wondering how long the sponges inside the cushions are going to last. After sitting on it for 1 month (at least 8 hours daily) the cushions have indentations on them in places where I sit and where I kneel. At this point in time that doesn't seem to bother me in any way, but only time will tell if they eventually flatten completely. Hopefully not. For that reason only I would rate this chair 4.5/5
