What We Like
- The Comfort Index is 70, the seventh highest in its category, built on a high-density foam cushion with a waterfall edge, a mesh back and a 120 degree recline.
- The lumbar adjusts in both height and depth, which earns the Ergo Score's full lumbar-support credit.
- Owners rate it 4.6 across 181 reviews, enough to earn full owner-rating credit.
Watch Out For
- The title advertises flip-up armrests, but the spec details confirm pivot adjustment only, which is why the arms are classed 1D.
- The listing does not state a seat height range or a gas lift class.
At a Glance
A mesh back, a lumbar that moves in height and depth and pivoting arms are the core of this AreShark's stated spec. The Ergo Score is 51.
Who This Chair Is For
- Buyers who want the cushion spelled out: the foam is listed at 3.15 inches thick.
- Anyone who wants arms that pivot out of the way, since pivot adjustment is stated.
Who Should Look Elsewhere
- Anyone who wants a headrest, since the listing states none.
- People above 300 lb, which is where the stated rating ends.
What the AreShark lets you adjust
The lumbar moves in height and depth, the arms pivot and the back reclines to 120 degrees, on a steel base under a mesh back. The listing does not state a tilt tension control.
Alternatives to Consider
Why consider: Includes a headrest where this AreShark listing states none, and is rated for 400 lb against 300 lb here.
