Innovative Ergonomic Design

To be a little more specific, note that the chair’s ridge backrest is designed with an S-shaped frame that matches the shape of the human spine, for which its close fitting is designed to perfectly fit the curvature of a user’s spine, which ultimately helps to release spinal pressure from your back and spine, while the chair’s seat features a flow waterfall arc design that allows it to provide an outstanding cushion support to your glutes and thighs.

Moreover, the chair’s backrest also integrates a built-in 2-way lumbar support that can have its height depth adjusted within a 1.9″ interval, and can also have its back tightness adjusted within a 1.2″ interval (meaning how close / how far it will stay pressed into a user’s lumbar area for a greater or lesser back support).

Not only that, but this ergonomic office chair also comes equipped with an adjustable headrest that can be rotated backwards within a 45° angle, and that can also have its height adjusted from 0″ (i.e. having it locked onto the top-side of its backrest) all the way up to 3.9″ upwards (i.e. lifted 3.9″ from the top of the chair’s backrest).

Adjustable Headrest

On top of everything already mentioned, the SIHOO M57 also comes equipped with adjustable 3-way (meaning 3D) arms, which can also be removed if you wish to do so.

Adjustable 3-Way Arms

The chair’s 3-way arms can be adjusted upwards and downwards within 5 different positions (i.e. in 5 different gears), can be adjusted backwards and forward, and can also be rotated left and right, all according to your personal preferences.

In addition, there’s also a built-in recline lock located under the chair’s right-side that can either be locked or ultimately unlocked to control the chair’s reclining mechanism, which more specifically, consists of a mechanical steel multi-function thickened explosion-proof reclining mechanism.

When unlocking the chair’s reclining mechanism, users can choose between three (x3) different reclining speed adjustments, for which the 1st-Gear allows the chair’s backrest to be reclined within 110º, its 2nd-Gear within 116º, and its 3rd-Gear within 126º.
