What We Like

It posts one of the highest Comfort Index scores in its category, built on a mesh back, a mesh cushion and an adjustable headrest.
The tilt is listed as a Smart Tilt mechanism, and recline goes up to 125 degrees.
The armrests flip up, and both seat dimensions are listed: 20.08 inches wide and 17.12 inches deep.

Watch Out For

The armrests are listed as 3D rather than four-way adjustable, and the warranty is 3 years.
The listing does not state a weight capacity, or whether the lumbar support adjusts in height or depth.

At a Glance

One of the highest Comfort Index scores in its category sits behind the M102C PRO, with a mesh back and cushion, Smart Tilt recline to 125 degrees and a headrest that moves in height and angle. Rated 4.6 across 507 reviews.

Who This Chair Is For

Sitters who lean back and want a defined tilt, with recline up to 125 degrees.
People who check measurements first: the seat is 20.08 by 17.12 inches.

Who Should Look Elsewhere

Anyone who wants more years of cover than the 3 years listed.
Anyone who wants four-way arms, since these are listed as 3D.

From Smart Tilt to flip-up arms: the M102C PRO adjustments

The lumbar is described as dynamic, and the tilt is a Smart Tilt mechanism with recline up to 125 degrees. The headrest adjusts in height and angle and the armrests flip up. The listing does not state whether the lumbar adjusts in height or depth, or whether the seat depth and tilt tension adjust.
