Benefits

Adjustability is where the M18 stands out, because small changes in angle or height can reduce strain over a long day at a desk. The W-shaped seat and waterfall front edge aim to relieve pressure beneath the thighs while the mesh back helps ventilation, which is useful if you sit in a warm room. The chair has passed BIFMA and static pressure tests according to the manufacturer, which points to reasonable durability for home or small office use.

Usage tips

It’s a good fit if you spend several hours at a desk and need a chair that adapts to different postures. Assemble on a flat surface following the eight-step guide, set the lumbar support to match the natural curve of your lower back and use the headrest for short breaks leaning back. Bear in mind that while the chair supports up to 150 kg, proper adjustment of seat height and tilt will make movement and comfort more effective.

Care & maintenance

Wipe the mesh and upholstered areas with a damp cloth and mild detergent when needed, avoid abrasive cleaners, and check caster wheels regularly to ensure smooth rolling. Replacement parts are available from the manufacturer within the three year warranty period if any component shows a fault.
