Additional Information
Adjustable backrest
Adjustable height to suit different users and ensure natural S curve of the spine. Twedts cushion promotes comfort and free movement for upper body. Independent adjustment of backrest angle to suit different individuals.
Adjustable lumbar support as standard
Hand pump can be used to adjust the air levels in the lumbar cushion to provide extra support.
Ultra comfortable waterfall edge seat
The seat of the RH Logic 400 provides excellent ventilation with a layer of wool on the base of the seat. Waterfall edge provides reduced pressure on underside of thighs to enhance circulation. Seat can be exchanged if damaged.
Easy to use controls for adjustable seat height, angle and depth
All the controls can be reached while sitting in the chair, facilitating ease of use. On the right side are the active controls you will adjust during the day. On the left side are the controls for basic settings which you need set only once. Colour coordinated pictorial controls show their function. Change height to improve blood flow to the legs and angle to provide better support to the back.
Easy to maintain optimal comfort and posture
Once you have adjusted the basic settings of your RH Logic you are ready to begin choosing your sitting position. Sit in the balanced free-float mode, with the rocking motion disengaged, tilt the backrest forwards if you want to lean forwards, and open the backrest angle when you want to lean further back. You will be surprised how gently but firmly the chair follows your movements.
Optional Armrests
8S Class A armrests are height and width adjustable. Optional 8E Class A armrest upgrades are also depth adjustable to account for different user arm lengths. We highly recommend armrests as they provide support for the shoulders, giving you comfort for long periods at your desk and ultimately long term health benefits.
Optional neckrest
Can be adjusted by height and depth to help provide support to the neck.

Soft floor castors for surfaces such as carpet, designed to minimise damage to floor.
Hard floor castors for surfaces such as laminate and concrete are restricted in movement once seated to stop the chair rolling away. Please specify hard floor castors when placing your order.
