The RH Logic 400 ergonomic office chair has a high back and offers outstanding performance, comfort and design for the office or home environment. It also features a wool layer in the seat and back to enhance ventilation and comfort.

The RH Logic series is designed to encourage active sitting and upright posture. It keeps you upright, making it easier to breathe, which in turn improves the oxygenation and circulation of your blood.

Our ‘from stock’ model has a black frame with black fabric upholstery. A seat slide and adjustable lumbar support are included. A neck rest and height-adjustable armrests are also standard but the chair can be specified without them at reduced cost.

The chair will need some simple assembly.

What our customers say

"Today Kevin visited me in Eastbourne, to set up a height adjusting desk, footstall, keyboard stand, mouse and chair. I just wanted to say how patient, and caring he was. He really helped me and I think he should be commended on how friendly, polite, informative and down to earth he was. Thank you Kevin and Ergonomics."
