Best Overall
DUMOS Big and Tall Office Chair, 500 lb Mesh, 4D Armrests
Our verdict: The most complete heavy-duty frame here, with 4D metal arms and a thick waterfall seat.
The DUMOS is a 500 pound rated mesh chair with a 4.33 inch thick seat cushion, adjustable lumbar that moves back and forth, and 4D metal armrests. The listing describes a 3-stage gas cylinder, a metal base and metal fittings throughout. A waterfall front edge is meant to ease pressure behind the calves.
It ranks first because it is the only heavy-duty chair here that lists 4D arms, which adjust in height, depth, width and angle, and the all-metal hardware. For larger users the arm adjustment matters more than headrest extras, since arms that sit too far apart force the shoulders to hang. It beats the YFO by the arm quality and the 3-stage cylinder, and it costs roughly the same.
Buy it if you are a bigger person who sits most of the day. The caveat is that no warranty length is listed, so confirm the seller's terms. It is a $100 to $200 purchase, comfortably below the $500 ceiling.
