The stool was purchased to sometimes to have a little more freedom for the back, legs and arms next to the office chair. Roughly the stool 4 parts: Stand with tires, gas lift, gas spring for cover and seat including height adjustment.. All is well and clearly packaged. When assembled the stool is relatively fast, only the split pins under the seat I could not completely push in until it stops despite tool. Even without tool with fingers helped brute force and skillful twisting anything, but the impressions of the splints on his fingers were visible for a long time. The gas spring is only inserted into the hole from the base, without anything snaps or is secured by cotter pin. The description remarks, one should put a few times vigorously on the stool, so that the gas spring is stuck permanently. If I ever have the stool in his hand without stand, I will grudge in this review. :-) The gas spring is slipped over a two-piece plastic funnel, which does not release the view of the interior even at any seat heights. After assembly of the tire is brought to the desired hardness using the included air pump. The height adjustment works with the single lever very good. Reduced to the smallest amount you can also push the stool also well under the desk if the space optics or space to do so. Working at a desk is so very good, longer sessions than 30minutes have not been tested. Experience will grudge later.
Conclusion: Quick assembled, stable impression, good seating comfort. The split pins and securing the gas spring prevent 5 stars. Update: after almost 2 months of use, the gas spring has not yet been released from the anchoring.
