Ergonomic Office Chair Specs
Weight capacity, warranty, seat-depth and lumbar adjustability, arm adjustability, BIFMA claim and price for 30 ergonomic office chairs — sortable.
The hard numbers behind our ergonomic-office-chair picks. Every chair's manufacturer-published weight capacity, warranty length, seat-depth and lumbar adjustability, arm-adjustability tier (2D/3D/4D or fixed), claimed ANSI/BIFMA X5.1 compliance, and current MSRP. Sort any column. The BIFMA registry (bifmacompliant.org) turned out to be a parked domain with no queryable product data, so `bifmaCertified` here is a manufacturer claim transcribed from the product spec page, not an independently verified registry lookup — see provenance below.

| Manufacturer-published maximum user weight | 99 = manufacturer's "limited lifetime" warranty, not a literal year count | Manually adjustable lumbar support; auto-flexing "always-on" lumbar (no user control) counts as false | Fixed, height-only, 2D/3D/4D/5D (4D = height, width, depth, pivot; 5D adds pad-width), or none; config-dependent chairs show the top available option (see basis) | Manufacturer's own claim of ANSI/BIFMA X5.1 compliance — not independently registry-verified (see provenance) | Current MSRP, July 2026, base configuration/fabric unless noted in basis | |||
