Sihoo M18 Ergonomic High-Back Office Chair with Headrest & Lumbar Support - Grey Mesh

Choosing the right chair for a home office or study matters as much as any other piece of furniture in the space. The Sihoo M18 brings together an ergonomic, fully adjustable design with a contemporary grey-and-chrome aesthetic that integrates neatly into modern interiors. THE LOOK The grey breathable mesh seat and backrest are framed in white, while the 5-star polished chrome base (70.0 cm diameter) with smooth dual-wheel castors adds a refined, professional finish. Overall chair height ranges from 109.0 to 127.0 cm, keeping proportions balanced in most standard-height rooms. COMFORT THROUGH CUSTOMISATION Seat height adjusts from 44.0 cm to 54.0 cm to work with a range of desk heights. The 51.0 cm wide, 25.5 cm deep seat is cushioned with an 8.0 cm thick W-shaped high-elastic sponge beneath a breathable mesh surface — supportive without trapping heat. The S-shaped mesh backrest (52.0 cm wide) includes an independent lumbar-support knob, and the backrest itself locks into three reclining positions: 108°, 118°, and 128°. HEADREST & ARMRESTS The padded headrest (30.0 cm wide, 18.0 cm deep) adjusts 8.0 cm vertically and rotates 45° — useful whether you are seated upright for focused work or reclined during a video call. Armrests adjust 7.1 cm in height, with a span of up to 69.0 cm, to position your arms level with your desk surface. PRACTICAL DETAILS Maximum load capacity is 150 kg; suitable for users up to approximately 184.9 cm tall. Wipe-clean mesh surfaces keep maintenance simple. A 5-year warranty provides lasting reassurance for your investment.
