SIHOO Doro S100
no budget ceiling
TechRadar's under-$500 winner — dual dynamic lumbar with 4 springs, a $1,000-plus mechanism at $330 a seat. Two desks stay under $700 total.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
This is a 5-year chair from a Chinese brand, not a 12-year one. Warranty support runs through email and RMA shipping, so expect slow service — and you are buying two, which is two possible RMAs. Capacity stops at 300 lbs, and mid-range chairs realistically last 3-7 years against Steelcase's 12-15.
Dealbreaker? Runner-up №1 — HON's lifetime warranty for $132 more ↓

Traps — this verdict avoids
Why the SIHOO Doro S100 is right for you
It avoids every trap below — and for two desks, no budget cap, it is the pick because it delivers:
Warranty is the spec
Budget foam flattens within 1-2 years of daily 8-hour use. Chairs with 12-year warranties outlast 1-2-year chairs by 5-10x — under 5 years of coverage is a red flag for this job.
The capacity gap
Budget chairs are rated 250-275 lbs, premium chairs 300-400 lbs — and real comfort tops out at 70-80% of the rating, not at it. The Branch Verve stops at 275 lbs, the Embody at 300.
Fit beats price
A wrong-size $2,000 chair causes more pain than a $400 chair that fits. Anything over $1,200 carries real fit risk bought online — the Aeron only works in the correct A/B/C frame.
