What We Like

Buyers rate it 4.7 across 1,149 reviews, which places it among the highest-rated chairs in its category.
The lumbar support moves both up and down and in and out, and the headrest moves in height and angle.
The flip-up armrests are four-way adjustable, and the seat covers 18.3 to 23 inches on a gas lift the listing labels Grade-4.

Watch Out For

It weighs 43 lb and is one of the pricier chairs in its category, so it suits sitters who value the headrest and lumbar range over easy moving.
Capacity is rated at 300 lb, below the 400 lb stated for the CAPOT.
The listing does not state a warranty term, a recline angle or a tilt mechanism, so ask the seller before ordering.
