A good ergonomic chair is the one piece of working-from-home kit that pays for itself in months: back pain costs more time than any other workplace complaint, and the chair gets blamed for most of it. The right chair isn't the one with the most adjustment dials; it's the one whose default geometry already fits you. Most people sit on the dial set the chair shipped with for years.

The specifications that matter are seat height range, lumbar adjustment (height, not just depth), and armrest 4D movement. A 40-50cm seat-height range covers most heights from 5'2" to 6'2"; less than that and the shorter or taller end of the household struggles. Mesh-back chairs run cooler in summer but can feel less supportive at the lumbar; padded chairs warm up by mid-afternoon but cradle the back. The Range and Robert Dyas both stock mesh and padded chairs from £40 to £700; Aosom UK runs mesh ergonomic from £45 to £340.

We compare ergonomic chairs across UK retailers daily and surface the price drops on long-running models. The grid below filters by mesh vs padded, with-armrests, height-adjustable, lumbar-support and price band, so you can match the chair to the body and budget without scrolling spec sheets. read more…
