Have this chair chosen because I needed a space-saving and comfortable chair for the time at the desk (not so much, maybe 1-2 hours a day maximum), since our old variant (swivel stool) was unusable for my back. I for almost an hour now sit on the "green thing" (the color is just plain cool) and have had no problems or pain. In the beginning it all seemed a bit cheap but no, I am absolutely satisfied for the price. and feel comfortable in the chair !! Even "just over roll to the printer or fax" works great (we have no carpet in the office). The fabric of the backrest can be washed because these can be removed through the zipper. The seat cushion is now no "exclusive padding" but it is sufficient and convenient! I think it's even good as the rest pleasant "nachfedert" The setup was extremely easy and I think is Inexperienced hikers can also people easily and in 10 minutes to create.
As long as the quality of the chair now ranges (1,2,3 ..... year) I do not know but for the price I'm satisfied if he is keeping for 2 years.
