Topstar OPEN X office chair

The black Open X office chair from Topstar is equipped with a high-quality, lockable synchronous mechanism that includes individual body weight adjustment. It comes without armrests and features the newly designed "Window" backrest, which is 580 mm in height and covered with a breathable mesh. The synchronous mechanism allows the backrest and seat to move back together when leaning back. Other benefits include the comfortable black trough seat with a rounded knee roll, which prevents blood congestion in the thighs. Thanks to Toplift technology, the seat height can be individually adjusted between 420 and 570 mm.

Topstar's Open X office chair, which comes with a 3-year warranty and is GS-tested, rests on a black base made of high-quality plastic and is equipped with load-dependent braked safety double castors for carpeted floors. These castors ensure that the chair only moves with brakes when unoccupied, preventing it from rolling away unintentionally when you stand up.
