Sihoo M57 High-Back Ergonomic Office Chair with Dynamic Lumbar Support & 3D Headrest - Black

Whether your home office is a dedicated study or a quiet corner of the living room, the Sihoo M57 is built to fit both the space and the person using it. Its clean black finish sits well alongside contemporary interiors, and the compact 70.0 × 70.5 cm (27.56 × 27.76 in) footprint keeps the floor area open. Three comfort zones work together to accommodate different body shapes and working styles. The 29.5 cm (11.61 in) wide headrest adjusts 8.5 cm (3.34 in) vertically and tilts 22°, providing tailored neck support for users of varying heights. A discreet hook integrated beneath the headrest serves as a practical hanger for a cardigan or tote bag — a small but useful detail for everyday home use. The dual-section backrest, 55.5 cm (21.85 in) tall, features a 30 mm floating lumbar unit that rotates 10° and moves 10° laterally. It settles naturally against the lower back during long periods of seated work, responding to gentle shifts in weight. The dual-curved backrest shape helps spread contact pressure evenly across both the upper (45.5 cm / 17.91 in wide) and lower (46.5 cm / 18.31 in wide) sections. Both the seat and backrest are finished in Dragon Skin mesh, which allows steady airflow — a genuine advantage in warmer rooms during UAE summers. Seat dimensions are 50.5 cm wide × 43.5 cm deep (19.88 × 17.13 in), with height adjustable via pneumatic lift between 46.5 and 56.5 cm (18.31-22.24 in) to match standard desks. The 3D armrests rotate, slide fore and aft, and flip fully upright, each pad measuring 22.5 cm (8.86 in) in depth. A five-star polished aluminium base fitted with dual-wheel casters glides quietly over tiled or wooden floors without scratching. CARE: Wipe mesh surfaces with a dry or lightly dampened cloth. Avoid solvent-based cleaners. Polish the aluminium base occasionally with a dry cloth to maintain its finish. Colour: Black. Warranty: 5 years.
