Office Star Ergonomic Knee Chair with Dual Wheel Casters

I was not very happy with this product. The chair was comfortable but after a few weeks the fabric on the kneeling section started to tear away from the bottom. As usual, Wayfair with their fantastic customer service gave me a refund.

I am 6'1" and about 230 lbs. I found that even at the highest adjustment for the seat, I could not find a comfortable position on this chair. I also found that after a few hours, even with breaks, the seat foam flattens out so much as to become hard and unsupportive. Three stars for ease of assembly and sturdiness.

The 'but' is that this particular chair is a bit too short. My toes are hitting the floor pretty hard and curled either forward or back. Not a big deal until you've done it a while and then the toes are either number or hurting.

Sat in if for half an hour working at the computer. That part was somewhat OK, but standing up and walking I felt muscles long unused. Sleeping that night was not a happy experience either. Never had a chair that made me so sore like this contraption. Will give it away and be glad it is out of the house.

very pleased--super comfortable, helps with posture and is cheaper than comparable chairs...

I love this chair. Bought two more for my kids.

Purchase was made for my Son,who sits at a Computer all day. Hes wanted this type of Chair for many years, but never took the time to try one. Hes using it every day and said its working very well.

I have just started using this chair and i am very pleased with it. it is comfortable and was easy to assemble.

The chair was easy to put together, arrived in record time, and is incredibly comfortable to sit in. The reason I gave it four stars instead of five stars is because I am only 5'4'' and I wish the seat tilted slightly forward which would allow me to be on my knees at the perfect angle. Regardless, the memory foam has enough give that after a few minutes I sink into the chair and the angle feels right. I would definitely recommend this chair. I use it for my home office after work hours.

Great chair!
