Had also tried the famous "X-Chair" which is slightly superior in features and precision of manufacture. However I couldn't justify spending that kind of money when this Hyken chair had the features and feel that I wanted at a fraction of the cost. I've been using it for about a month and a half and it feels so good. Of course you can slouch in any chair if you want to but this makes sitting with proper posture very pleasurable
The chair came with a ruffled up box but the chair was undamaged. I gave it 4 stars because the wheels look cheap and I didn't see ball bearings so this means it is not super smooth and will wear out sooner than later. On the good points it is comfortable and the mesh design will keep me cool during hot summers.
