What We Like
- BIFMA and SGS certifications are both listed.
- High-density foam makes up the seat cushion.
- 907 reviews average 4.6.
Watch Out For
- The Adjustability sub-score of 0 ties for the lowest in its category: armrests, lumbar adjustment, seat height, seat depth, advanced tilt, tilt lock, tilt tension and recline all score zero.
- The warranty term is not stated, and neither is a recline angle.
At a Glance
A U-shaped lumbar and BIFMA and SGS marks keep the spec sheet of this DUMOS short.
Who This Chair Is For
- Shoppers who want a leather-look seat.
- Sitters who want a U-shaped lumbar.
Who Should Look Elsewhere
- Anyone who wants armrests of any kind will find the title calls this chair armless.
- Buyers who want to compare a warranty term, since the listing does not state one.
Tilt and height details the DUMOS listing leaves unstated
The title says the height is adjustable, but the listing does not state a seat height range, a tilt mechanism or a recline angle.
Alternatives to Consider
Why consider: A 135 degree recline and a tension control on the tilt are stated for it, neither of which this listing gives.
