SIHOO M18
$3 under your $150 line
The only chair here with any published durability test — 11 sources and 15,000+ Amazon reviews back it, and it rates 330 lb where the rest of this tier guesses.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The arms only move 2D. Height and pivot, no width or depth — and there is no seat-depth slider either, so a long or short thigh cannot be dialled in. True 4D arms and a seat slider do not exist under $200; they start around $280.
Dealbreaker? Runner-up №1 — MALOL gives you 3D arms for $30 less ↓

Traps — this verdict avoids
Why the SIHOO M18 is right for you
It avoids every trap below — and for just me, under $150, it is the pick because it delivers:
Capacity is a claim, not a certificate
No chair on this page holds a third-party ANSI/BIFMA X5.1 listing. SIHOO publishes a vendor test pass for the M18 — BIFMA X5.1 plus a 1,136 kg static-pressure test — and that is the only one. Every other rating here, from 220 lb to 350 lb, is an unverified manufacturer number.
A bucket seat is not a task chair
Racing-style gaming chairs and task chairs now cost the same but do different jobs. The GTRACING is rated 300 lb while its usable seat is only about 15 inches wide — independent testing puts its real comfort window at 5'4"-6'1" and under ~230 lb. Route by how you sit, not by how it looks.
The 12-18 month cliff
Foam cushions in sub-$150 chairs compress noticeably within 12-18 months of daily 8-hour use, and gas-cylinder sag is the other common failure. Warranties here run 1-3 years — Mimoglad's five is the exception, Ticova's single year the floor.
