Work Smart™ 28.00-in x 17.00-in Black Ergonomic Knee Chair is rated 4.1 out of 5 by 11.
Rated 4 out of 5 by from My top choice for an office chair I originally purchased this chair 7+ years ago to use at work, as I was experiencing recurring pain in my lower back. Shortly after I assembled the chair and got used to using it, my back pain went away. Now, I've ordered this replacement because one of the metal pieces holding a knee pad to the crossbar has broken. After using this chair constantly for at least 7 years, I can report that it is well worth the money and is my top choice (I also have one for my personal computer, and my sister bought one too).

Rated 5 out of 5 by from One Great Product This chair increased my productivity by 50%. My back no longer hurts after sitting for several hours. Mobility around the desk area is great with this chair - with the flick of the toe I scoot across the room. Never missed the lack of back support. No desire to ever slouch back and relax. It does take a couple days to get the shins and toes adjusted to the new pressures. Fun chair. Buy one and try

Rated 4 out of 5 by from Met My Hopes And Expectations I had a wooden, non-adjustable model in college and remembered it being very comfortable. I recently hurt my back and need to sit proper at my desk so I decided to give this style of chair another shot. I am 6'2", 200 lbs and was hesitant about this chair fitting my frame, but so far have been pleasantly surprised. The chair went together easily, is very comfortable, and a purchase I do not reg

Rated 2 out of 5 by from It's Ok I have chronic low back pain and sometimes cannot sit for very long. I thought, based on the reviews, that this kind of chair might help. It doesn't. I actually feel worse after sitting in it for awhile. That might improve if I was more conditioned to sitting in it - but I think it takes some measure of core abdominal and low back strength. It is height adjustable, but seems to only go betwee

Rated 5 out of 5 by from I'd Buy Another One! I spend a good deal of time at my computer, and this chair really helps with my posture, and helps keep my wrists in their proper position on my keyboard. I had read with trepidation some of the reviews regarding difficulty assembling this product, but I had no problems whatsoever. It took maybe 5 to 10 minutes to put together with no issues.

Rated 5 out of 5 by from Nice!! Easy order, timely shipping! Awesome chair. Don't pitch your old chair right away. Sitting a long time incorrectly will mean it may take some time to adjust to the proper way to sit at your desk. It is worth it!

Rated 3 out of 5 by from Good Value But If the seat cushion had a higher quality , higher density memory foam the chair would be perfect. The foam compresses too much leaving you sitting on hard wood surface.

Rated 3 out of 5 by from Not Bad The chair was easy to assemble and is quite sturdy. The foam seat and knee pads are,however, too soft for support during a long computer session.
