Nouhaus Ergo3D
$15 under the $300 ceiling
The shared-home-office answer across 11 sources — 4D orbital armrests and a 3D lumbar that re-sets to a second body in seconds.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It has a body-size window. Nouhaus is best for users under 275 lbs and under 6'1" — if either person sharing it is taller or heavier, the fit falls apart and no amount of armrest adjustment fixes it.
Dealbreaker? Runner-up №2 — the SIHOO M18 is rated to 330 lbs ↓

Traps — this verdict avoids
Why the Nouhaus Ergo3D is right for you
It avoids every trap below — and for two, no budget cap, 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.
