Buyer's Guide
What to Check Before Choosing an Office Chair?
Seat height
Your feet should sit flat on the floor, with knees close to a 90-degree angle.
Lumbar support
The backrest should support your lower back without forcing an awkward posture.
Armrest position
Armrests should help your shoulders relax, not push them upward.
Recline control
A good recline should feel stable and usable, not loose or decorative.
Sihoo vs Others
A lower-priced office chair can work for short sitting periods. The difference shows up when you sit for longer hours and need better adjustment, back support, and build quality.
