It is important that the chair fits every user no matter their shape or size. In order for a chair to be ergonomic it needs the minimum basic adjustability features:
• Basic features are seat height adjustment, height & width adjustable arm rests and lumbar support. • Additional features are back, height and seat depth adjustment, adjustable lumbar height, adjustable lumbar curve, personalised pelvic modules, coccyx relief cut out, memory foam, seat depth, tilt & back angle control, extra forward title as well as tension control, adjustable headrest for height & tilt. • Speciality chairs can also be provided for users of up to 30 stone.
The major characteristics of a seating unit are as follows:
• Seat height adjustment allowing feet to be flat on the floor and arms at desk level. • Lumbar support of an ergonomically designed seat is vitally important on relieving back aches and strains over a working day.
