Product description – RH Extend UNI 120
RH Extend UNI 120 is an ergonomic office chair with a high backrest that can be raised and lowered to adapt to your body and provide optimal support throughout the working day. The headrest is adjustable in both height and depth to provide extra comfort and relief for the neck muscles. The armrests can be adjusted in height, width and also rotated to suit different working positions.
The seat is designed with a rounded waterfall edge that reduces pressure on the thighs and contributes to good blood circulation. It is also 8 cm deep, which allows the chair to be adjusted to different body lengths. For best seating comfort, you should adjust the seat depth so that there is about two fingers' space between the seat and the crease of the knee.
RH Extend UNI 120 has a large back and a medium-sized seat. As standard, the chair comes with castors for hard floors, armrests, headrest and a base in silver-lacquered aluminium. The upholstery is uniform in black fabric, which gives a stylish impression. The adjustment controls are clear, easily accessible and easy to use even when you are sitting down. This makes the chair suitable for both individual use and for workplaces where several people share the same chair.
Equipped with a tilt mechanism that follows the body's movements and provides support in all working positions, the RH Extend is a practical choice for flexible office environments.

RH Extend 120 UNI
RH Logic – ergonomics in focus
The philosophy behind RH Logic is based on the unique two-point principle 2PP™, which gives the body both variety and support to facilitate movement. By adjusting the seat depth, angle and height, the chair can be completely adapted to your body for maximum support, relief and improved blood circulation. The sloping seat reduces pressure on the thighs and thus contributes to better circulation in the legs.
Sitting upright while having the freedom to move allows you to breathe better and provides the body with more oxygen. With the help of the so-called Tvedts cushion, the shoulder blades are gently moved back, which opens the chest and promotes deeper breathing. The result is increased concentration and higher performance.
Swedish research studies have shown that RH Logic has a positive impact on both posture and performance after just a short period of use. The chair provides support in all working positions, encourages movement and makes it easier to sit properly and breathe freely.
