Sihoo M57 Pro with built-in footrest - a 150kg-rated ergonomic chair that reclines to 130 degrees.
The M57 Pro is Sihoo's high-back mesh chair, rated for users up to 150kg. The backrest has four locked positions holding an S-curve that follows the spine, and the lumbar support adjusts for both height and depth, so you can set the pressure where your lower back actually wants it. The headrest is a double-joint design that moves without you having to reset the whole back. Reclining runs from 90 to 130 degrees through an auto-balance mechanism with three angles you can lock. Armrests are 4D linkage - up and down, in and out, fore and aft, plus a 360 degree pivot. Seat height travels 10cm. A built-in footrest slides out for reclined sessions, and the base is aerospace-grade aluminium alloy on silent castors.
