What the community says
MMORPG.com gives it 8/10, highlighting the four-way lumbar and the firm cushion; TechGearLab rates it 66/100, noting low-glide castors and very stiff controls to operate. Consensus: the best entry-level ergonomic chair under €200, with the caveat that the armrests don't adjust for width.
Good fit

Strengths
- Budget price with a high mesh backrest
- Dual adjustable lumbar support (vertical and horizontal)
- Headrest adjustable in height and angle
