Even for long working days ...

... This office chair is suitable. Very well made. The assembly is easily accomplished even for non-techies and Grobmotoriker. Only the pressing of the foot rolls requires some force.
Fears of the fabric can lead to electrostatic charges and thus to unsuitability on the computer workstation, have not materialized.

I use the chair in alternation with the Topstar ST59S10 swivel stool Sitness 23 / upholstery fabric black / footplate wood with stainless steel cover, which I find very pleasant as well - but only for max. 4 to 5 hours of continuous use.

After a course change to the Sitness 40 which acts as a back support pelvic support is then very relaxing.

Conclusion: The discussed here Sitness 40 makes sitting bearable even on a long computer working. More fun prepares the seats even more agile on the swivel stool Sitness 23rd
