Ergonomic Kneeling Office Chair with Gray Fabric - Adjustable Mobile Wooden Chair for Home & Office - Perfect for Posture Support, Back Pain Relief & Long Work Sessions

I opened the box this morning and put the chair together in about 2 hours. The materials and craftsmanship are excellent, especially considering how low the price is. The design is good. The cushions are soft enough to pad your knees, and the height adjusts by simply turning a brass knob (no need to take the whole chair apart and screw it back together in a different position). It has a very attractive design. Compared to other kneeling chairs in the same price range, I like this one. The assembly instructions consist of a detailed pictorial diagram, with no verbal explanations. This should not cause you difficulty if you have assembled furniture in the past. If you have never used a kneeling chair before, you will find this style of chair helps keeps your back and abdominal muscles toned if you have to sit all day. However, if you are not already in good physical condition, this style of chair might cause you some discomfort. It has a label saying it will only hold 200 pounds. It can cause some discomfort on your knees, which can be alleviated by taking short standing breaks every hour or so.P.S. - I have been using the chair for several months. The knee plate gradually came loose, and you could feel it rocking back and forth. Today I got out the Allen wrenches & spent about 10 minutes tightening all the screws. Now the problem is fixed & the chair seems good as new. Shortly after I started using the chair, I bent too far forward to pick up something off the floor, and I tipped the whole chair over and landed on my knees on the floor (double ouch). However, I think that was a matter of "operator error" and nothing went wrong with the chair; just be careful and don't lean over too far, to avoid overbalancing.
