As mentioned in another review, the rollers are very difficult to turn. It draws more on the ground, not only in carpet, even with parquet. With parquet still is exacerbated in that the rollers do not rotate due to the low rolling resistance to the chair fixed to the axis.
This means that the chair does not feel really safe, since the wheels are partly so that the wobble chair. If "free" back this goes so far that one is afraid to upset backwards (with about 100kg bodyweight)
Construction is easy, seat is ok, although nothing feel of the upholstery at 100kg, it is too soft to really bolster. The back and the adjustable support are pleasant.
Still, no other roles (accessories, costs about 25% of the chair) can not really recommend the chair
UPDATE: as feared, the roles of the weak point. One is when you lean back broken under me (the rear at the time). Although the chair tipped not to, but he has given me and the others present an ... interesting moment of shock.
On the plus side, the roles are compatible with other chairs. My previous office chair served as a roll dispenser. These have my weight and my "Kippeleien" endured for many years and also roll better than than the enclosed ... a pity that such errors occur after a few weeks.
new Conclusion: with the included roles and more than 90kg of body weight definitely change roles or take another chair. The 3 star rating is because in principle it is not a bad seat, but the wheels are plastic waste.
