The Adapt 511 Ergonomic Chair is a compact, highly adjustable office chair designed to provide personalised support and comfort throughout the working day. Part of the Adapt 500 range from Ergochair, it follows the same ergonomic principles as the Adapt 600 series while offering an accessible entry point with a wide range of customisation options.

The Adapt 511 is designed around the individual, recognising that there is no one-size-fits-all approach to ergonomic seating. With extensive adjustment options allowing the chair to be tailored to different users and working requirements.

Standard features include inflatable lumbar support, a memory foam seat, seat slide adjustment and a free-float mechanism, which encourages healthy movement while seated. With its combination of ergonomic support, adjustability and customisation, including an optional heat pad system, the Adapt 511 provides a flexible seating solution for those who spend extended periods working at a desk.
