DUMOS Ergonomic Gaming Desk Chair

Will the seat cushion and lumbar pillow harden or flatten after long-term use?

Seat uses spring + high-density foam; lumbar pillow uses high-resilience memory foam. Passed long-term durability tests. Designed to resist abnormal sagging.

Does this chair fit users 6'2" / 220 lbs+? Is the footrest too short?

Fits up to 6'3" / 275 lbs. Footrest extends when backrest reclines – most comfortable for users ≤6'1". Taller users can use it as light leg support, not full weight-bearing.

The chair spins too freely. Can rotation be locked?

Smooth 360° casters, no lock. You can replace with locking casters (universal fit). Thick metal base adds stability and reduces unintended rotation.

Are the armrest screws secure? How often do they need retightening?

Anti-loosen screws with metal inserts. Check every 6 months under normal use. No frequent retightening needed. Upgraded brackets available if issues arise.

Does the seat tilt when reclining? Does the backrest spring back automatically?

Backrest adjusts 90°–135° while seat stays flat – prevents thigh lift. No auto‑return (safety feature prevents pinch). Push back upright gently with hand or back.
