Mesh Chair with 4D Arms and Sliding Seat Black

Mesh Chair with 4D Arms and Sliding Seat Black: an ergonomic chair in black with the adjustments listed rather than a vague claim.

Task chairs listed by what actually adjusts: seat height, seat depth, backrest height, lumbar position and firmness, arm height, width and angle, and recline tension. A chair with five adjustments that fit you beats a chair with ten that do not, and every listing states the seat height range and the tested weight capacity.

• Weight capacity: 130 kg tested

Setting it up properly

Chairs can be returned within 14 days of delivery if they do not suit you, unused and in their original packaging. A chair is a personal fit and nobody should be stuck with the wrong one. Desks are built to BS EN 527 for office work tables and chairs to BS EN 1335 for office work chairs, and every product is tested to the stated load. We publish the tested weight capacity rather than a marketing figure.

Which option to buy

Standard is the standard specification, which fits most people between 1.55 and 1.90 metres tall. With Headrest is with an adjustable headrest, worth having if you recline to take calls or read. With Headrest and 4D Arms is with a headrest and arms that adjust in four directions, which is what gets your shoulders relaxed. We sell ergonomic furniture and explain how to set it up properly. Every listing states the height range, the weight capacity and exactly what adjusts, because a chair described only as ergonomic tells you nothing. If a cheaper product in our range does what you need, the listing says so.
