RH Form Philosophy of Ergonomics

Ever since they started in 1975, RH have used the human form as the blueprint for their ergonomic office chairs. We agree with their belief that a chair should adapt itself to you, not the other way around. An RH Form chair is designed to fit your body. You can move, stretch and vary your position, all while sitting upright. The result? Suddenly you have more energy for your work and your leisure time.

Smart Adjustments

The controls for the height and depth of the seat are all conveniently located on the right-hand side of the chair. The correct height improves blood flow in the legs while the correct seat depth provides greater comfort and support. Pictograms make controls easy to understand.



The tilt mechanism is infinitely adjustable, with a smooth action that can be locked in any chosen position. Dynamic seating means the chair follows your every movement regardless of working position providing complete support, enabling you to always sit correctly and breathe properly.

The RH Extend can also come with a Backrest Angle Adjustment option. This option allows you to set the angle of the backrest and lock it in that position.

The resistance of the tilt mechanism is simply adjusted according to body weight and height. This allows the chair to follow your movements without the need to exert muscular force to push the chair into new positions. The control is located beneath the seat.

Accessorise your RH

Castors for both hard and soft floors are available. Armrests are optional but are recommended since they provide relief for the shoulders. Armrests are optional but are recommended since they provide relief for the shoulders. Two armrest variants are available. Both can be adjusted by height and width, while one can also be adjusted by depth and the other can be rotated 360 degrees.

In addition to the standard accessories the Extend can come with optional decorative stitching, coat hangar and neckrest. We include the cassette insert for the neckrest as standard so you can purchase a neckrest at a later date if necessary.

Superb Seating

The seat provides excellent support and has a waterfall edge to reduce pressure on the underside of the thighs, aiding circulation. It is also designed to keep you positioned in the middle of the seat, even when it is inclined forward. Both the seat and backrest pads are easily exchanged. Should they become worn or stained or you want to change them for any other reason, you don’t need to replace the entire chair, which is not only cost effective and practical but also great for the environment.



The robust backrest is available in two sizes and is equipped with a “Tvedts” cushion, providing superb support for the whole upper body. The shape of the backrest encourages movement and the height is adjusted with the simple push of a button.

Economical Design

Both the seat and backrest pads are easily exchanged. Should they become worn or stained or you want to change them for any other reason, you don’t need to replace the entire chair, which is not only cost effective and practical but also great for the environment.

Guarantee

An RH chair is built to withstand stress and to last. Before it leaves the RH factory it goes through rigorous tests and checks. For this reason, RH provide a five-year guarantee on RH Chairs.
