Office Star Work Smart Ergonomically Designed Knee Chair with 5 Star Base and Memory Foam is rated NaN out of 5 by 12.
Rated 5 out of 5 by from Great chair! I got the chair today 7/11/13 and it was super easy to put together (yay teamwork and coworker!). I was impressed how the knee part of the chair moves with you. It's not obvious when you're standing up and moving it with your hands but when you sit down, it moves with your body allowing you to adjust your posture with ease. The cushions are really thick but I really think in time it will have to be replaced, I'm assuming the time frame will depend on your weight. You can spin in the chair, great for the office when you're being called from behind, the frame is solid and sturdy - much better than a wood frame that I've seen. A coworker has the same type of chair but in a wood frame and the wheel keeps breaking off with little movement. The chair's height can also be adjusted. Great feature for the workplace since everyone's desk height varies. I let my coworker use it for the remainder of the day and she loved it. Totally wants one. Really does help the lower back and will also allow you to focus more on your core which helps with the back pain. Please be aware that your shins will hurt and it will take some getting use to without a back support for about a week or two.....much better than back pain....depending who you are I guess. Hope you enjoy!

Rated 5 out of 5 by from More than meets our expectations My wife, who is 5'2" spends many hours at the computer. She always used a doughnut cushion to relieve her discomfort and the often swelling of her feet. This knee chair has met all of our expectations. The chair was easy to assemble. We were able, working together, to have it ready for use in just a few minutes. My wife uses the chair even for sitting at the dinner table. She has a big smile every time she sits on it and finds it very easy to get on and off. The cushions are very comfortable and the chair is very stable. She feels rested as soon as she sits on the chair. Also, she is able to scoot about as she does her work. Of course a bit of caution is recommended and it is definitely not recommended for children. This chair is an excellent value and we recommend it to anyone who has a posture problem.

Rated 1 out of 5 by from The bottom support is not adjustable Liked the cushions. The bottom support is not adjustable, so you end up sliding down most of the time. Will return it today.

Rated 4 out of 5 by from Well designed knee chair This chair meets my needs to have a correct posture while sitting. Just be careful of the floor beneath the rollers. The chair could slip from under you.

Rated 5 out of 5 by from Lilmouse2u I loved the chair. The directions need to be more specific about the height adjustment.
