Fit beats feature count
A long spec list does not guarantee comfort. Seat height, seat depth, lumbar position, and arm height decide whether the chair works through a full day.
Return policy is part of the product
Chair comfort is personal. A clear return path matters because two people with similar height can still need different seat depth or back support.
Avoid gaming-chair shortcuts
A thick seat and dramatic backrest can feel good at first and still be wrong for typing posture. For desk work, adjustment range usually matters more than styling.
Check the exact configuration
Office chair listings can vary by arms, lumbar, fabric, and seat controls. Confirm the version before comparing price.
