Ever since RH started in 1975, they have used the human form as the blueprint for their ergonomic office chairs in the belief that a chair should adapt itself to the user, not the other way around. An RH chair is designed to fit the user's body. You can move, stretch and vary your position, all while sitting upright.
The RH Logic 400 is an evolution of the successful RH Logic 4. Its design is inspired by the human form, and by two joints in particular - those of the knee and the hip. RH call it the two-point principle and you'll notice the effect as soon as you sit down.
First of all, the vertical movement of the front of the seat is minimal when leaning backward or forward. Your feet always remain in contact with the floor, minimising the pressure against the underside of your thighs, which eliminates numbness due to restricted blood circulation. Secondly, the backrest height remains constant, regardless of the seat angle. Consequently the lumbar support is always in the correct position, which helps facilitate an upright posture. You can also increase or reduce the lumbar support using the lumbar pump.
But the RH Logic 400 offer so much more. The seat and backrest feature extra padding and are contoured to distribute weight more evenly and to maintain an upright posture. You can adjust the angle of the backrest without losing lumbar support. The controls are intuitive and conveniently placed - easy to set and adjust. The chair follows your movements while maintaining perfect balance.
A number of custom options are available on the RH Logic 400 at additional cost. Coccyx relief cut-outs in the seat, viscoelastic seat cushioning and additional seat padding are some of the special build features available. Please call us if you have specific requirements.
The RH Logic 400 is available in three versions - Standard, Elegance (distinguishable by the upholstery on the back) and 24 hr, with a variety of accessories. For further details, please download the Logic range brochure and price lists in PDF format, using the links below.
The Chalmers Report, published in 2013, showed that both health and performance improve when the RH Logic 400 is used during computer work, compared to other office chairs. This comprehensive research study was conducted in Sweden by Chalmers University of Technology and Ergonomhuset in Gothenburg, together with Stockholm University.
