About

The M56C is the lower-priced chair in SIHOO's M56 line. It has a dual-section mesh backrest 20.3" (51.5 cm) wide with a flexible lumbar panel that moves with the backrest (SIHOO calls it ultra-wide dynamic lumbar support; no manual adjustment is listed), a W-shaped foam seat cushion, a headrest that moves up and down and tilts, and armrests that adjust up and down only. It comes in Black.

Official figures (SIHOO US store): overall size 28" wide x 27" deep x 44"–52" high, seat depth 17.1", recline up to 125° with one locking position, and a product weight of 37.15 lb. SIHOO's UK dimension drawing gives a seat width of 51 cm and a backrest height of 56.5 cm. The US page states the load rating two ways: 330 lbs in the spec list and 300 lbs in the feature list and FAQ; we show 300 lbs. SIHOO does not publish a seat height range or a recommended user height for the M56C.

Warranty: 3 years (SIHOO US store).

Price: the SIHOO US store lists $184.99 and shows no separate sale price. On 2026-10-13 the page showed a Pre-order button, so check availability before ordering.

What to check before ordering: the armrests move only up and down, the recline has one lock position, and SIHOO publishes no seat height range, so compare the overall height range with your desk.
