16,000+ Amazon ratings and the highest weight capacity here — FindingDulcinea's editor's choice and the safest sub-$150 bet of the 10 compared.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
The armrests are 2D. Height and in-out only — no swivel, no forward slide — and that is the whole compromise against the $200-290 picks. It also sits just $3 under the cap, so one normal price swing puts it over $150.
Dealbreaker? Runner-up №1 — Marsail brings 3D arms for $28 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:
Yesterday's budget champion
The sub-$300 shelf moves weekly — Amazon and brand-direct sales swing these prices by $30-80 a week, and four 2025 favourites (Doro S100, Doro C300, OdinLake L2, Branch) now list above the $300 ceiling. A year-old "best under $300" list is a fiction.
Capacity is a ceiling, not a target
Weight ratings run 250-350 lbs, but they are manufacturer maximums — stay 20-30% below the rated maximum for real durability. The Branch tops out at 275 lbs, tighter than the 300 lb category baseline.
The warranty cliff
Most sub-$300 chairs carry 1-3 year warranties against 5-12 years from Steelcase and Herman Miller. Price in a replacement before you call a $150 chair cheap.
