Fit Guide

A comfortable seat height is about a quarter of your body height. Here is how this chair's listed seat range lines up (how we rate).

Your height	Seat range	Fit
4'11" to 5'3"	20.1 to 22.4 in seat (ideal about 15.3 in)	Seat may be too high
5'4" to 5'7"	20.1 to 22.4 in seat (ideal about 16.4 in)	Seat may be too high
5'8" to 5'11"	20.1 to 22.4 in seat (ideal about 17.4 in)	Seat may be too high
6'0" to 6'3"	20.1 to 22.4 in seat (ideal about 18.4 in)	Seat may be too high
6'4" and up	20.1 to 22.4 in seat (ideal about 19.3 in)	Seat may be too high

What We Like

The headrest adjusts in height and angle, and the lumbar support is dynamic with height adjustment.
The seat depth is marked adjustable, so the seat can be matched to your legs.
Adjustment is its strength: it has one of the higher Ergo Score adjustability ratings in its category, and the title adds a footrest.

Watch Out For

The seat starts at 20.1 inches, one of the higher minimum seat heights among published chairs, so shorter sitters may find it sits high.
The listing does not state a weight capacity, a warranty term or the back material, though the title calls the seat mesh, so those basics are unconfirmed before you buy.

At a Glance

A footrest, a dynamic lumbar and an angle-adjustable headrest stand out for the ErgoX Premium, whose seat runs from 20.1 to 22.4 inches high. The listing does not state its capacity or warranty, and 393 reviews average 4.3.

Who This Chair Is For

Sitters with longer legs who want a footrest and a seat that starts at 20.1 inches.
Buyers who want separate headrest angle and seat depth controls.

Who Should Look Elsewhere

Shorter sitters, because the lowest seat height is 20.1 inches.
Sitters who want a seat that covers a wide range of heights, since it only spans 20.1 to 22.4 inches.

What actually adjusts on the ErgoX Premium

The listing marks the lumbar as dynamic with height adjustment, the headrest as adjustable in height and angle, and the seat depth as adjustable. The seat height ranges from 20.1 to 22.4 inches. The title mentions recline and tilt functions, but the recline angle and the tilt mechanism are not listed, and neither is lumbar depth or tension adjustment.
