Stool in very good quality

Delivered very quickly.
Assembly is very easy. Even for people without technical knowledge - which can use a screwdriver.
No chemical smell.
Rolls are smooth (also on carpet with 90 kg load).
Seating is comfortable.
No quality defects found.
Variable height is sufficient (there sit people from 1,65m to 1,85m height it).
Depending on how hard you are, the Hydraulick sag more or less. But is not worth mentioning.
For long-term durability, I can not say anything yet.
If the stool is broken by end of warranty, I just buy myself a new - for deeeeen price ...
