RGP's 400-Hybrid combines the patented split backrest design with a more traditional triangular shaped flat seat cushion. Built with the same hydraulic mechanism used in our 400 series line of chairs the seat and back can float following ones' movement. The triangular shaped seat cushion relieves some of the pressure on the back of the thighs.

The Active Seating is further enhanced by the adjustable heights of both the backrest and the stool itself. Arm supports are available to relieve the neck arms and back while allowing full range of motion. Postural changes as a result of use of the 400-Hybrid have proven effective in promoting work productivity eliminating daily fatigue and pain and increased health and well-being.
