Sitting for long hours in a desk chair, especially one with poor back support, can cause lower back pain, neck pain, or exacerbate an existing condition, according to Spine-Health.com. Sitting in one position for long periods of time or slouching at a computer stretches the ligaments and strains the discs in your back. An ergonomic desk chair can relieve some of that tension by providing back support and promoting good posture. All of the following chairs meet the standards of the American National Standards Institute (ANSI) for ergonomically sound desk chairs.
The Ergo Mesh Medium Back Task Chair
The Ergo Mesh Medium Back Task Chair is fully adjustable to maximise personalised comfort. The chair has settings that allow you to change the depth of the seatback and the height of the seat, the tilt of the chair, the tension in the back of the chair, and even the height of the arm rests and the sensitivity of the chair's swivel. The seat of the Ergo Mesh Medium Back Task Chair is made of contoured foam, while the back is made of a synthetic mesh. The chair requires home or office assembly, and runs about £130. It comes with a 5-year warranty.
The Office Star Deluxe Ergonomic Chair
The Office Star Deluxe Ergonomic Chair is a leather adjustable seat that allows you to change the seat height, and tilt tension and armrest height. The chair comes with a 1-year upholstery warranty, a 2-year moving parts warranty, and a 5-year non-moving metal parts warranty. The back and seat are made of leather-covered foam. The Office Star Deluxe Ergonomic Chair is usually priced around £182.
The Herman Miller Mirra
The Herman Miller Mirra is a size-adaptable chair that comes with several manual adjustments.

The Basic runs about £422 and the Fully Loaded about £552. The seats of both are covered with a synthetic Tri-Flex material, and the backs are made of synthetic mesh. They come with a 12-year warranty.

The Steelcase Leap comes with a 3-year fabric warranty, a 5-year warranty on the seat mechanisms, and a lifetime warranty for the rest of the chair.
