Steelcase Series 1
Ergonomic office chairs — mid-range contract-grade task chair · Reviewed by Katie · amazon.com live, Sept 9 2026

Why it scored a 82
At $499 the Steelcase Series 1 is the contract-grade task chair that Wirecutter and most roundups call the best office chair under $500. Warranty leads at 96 on a 12-year, 24/7 parts-and-labor policy, and Quality scores 86 for a 400-pound rating, BIFMA Level 3 certification and a chair that ships assembled. Features trails at 66: the lumbar adjusts in height only, the recline has three stops rather than continuous tension, and the seat runs firm and small enough that owners over six-foot-one or 210 pounds call it cramped. It is for an average-size user who wants a durable, warranty-backed chair rather than the most adjustments.
