Sihoo M57 Pro Ergonomic Office Chair (Black)

Product Description

Sihoo M57 PRO Ergonomic Office Chair, Computer & Gaming Desk Chair — 4D Adjustable High-Back, Breathable Mesh, Dynamic Lumbar Support

Key Features:

Level-up your seating with a double-joint flexible headrest for custom neck relief; a 4-position integrated S-curve backrest that mirrors your spine; height- & depth-adjustable lumbar support in high-polymer elastomer; 4D linkage armrests (up / down, in / out, fore / aft, 360° pivot); plus an auto-balance mechanism offering a silky-smooth recline from 90°–130° with three lockable angles. Seat height adjusts through 10 cm of travel to suit every workstation.

High quality & easy assembly: Tested to BIFMA × SGS standards and cleared a 2,000 lb static-pressure trial—so it’s rock-solid up to 130 kg. Each chair ships with clear, eight-step instructions; you’ll have it bolted together in about 15 minutes.

For long stints at the screen: Breathable PE + polyester mesh keeps air circulating, meaning no sticky back even on sweltering summer days. The hard-wearing weave resists sagging or fraying, so eight-hour sessions are a breeze and maintenance is as simple as a gentle warm-wash rinse.

Premium materials: Aerospace-grade aluminium alloy base pairs with silent, floor-friendly castors for effortless glide. The reinforced PP + fibre dual-back frame stays rigid under load, while PU-topped armrests wipe clean in seconds.
