Product description
- Includes head rest and arm rests
- Large contoured seat with Sitness joint
- Stable plastic five star base, black
- Net/upholstery combination cover
- Safety double castors in modern spoke design
- Synchronous mechanism with adjustable spring tension and infinite locking
The Topstar SITNESS RS office chair combines a height adjustable backrest with headrest and a mesh/upholstery combination. Headrest and arm rests are included and complement the various adjustment options of the swivel office chair.
The large contoured seat is equipped with the SITNESS joint, which enables three-dimensional mobility of the seat surface. This allows the seat surface to move in different directions. A synchronous mechanism also enables coordinated adjustment of the seat and backrest tilt.
The spring tension of the synchronous mechanism can be adjusted individually to the body weight. In addition, the mechanism is infinitely lockable. This provides various options for adapting the seating function to the respective user and the desired sitting position.
The large, stable plastic five-star base is finished in black. Load-dependent braked safety double castors are suitable for carpets and complete the equipment. The upholstery fabric vinyl Lotos consists of 65 % PES, 30 % CO and 5 % CV.
