What does this office chair do for you?
The Topstar Sitness RS X office chair is designed for long periods of sitting at your desk with maximum comfort and support. The chair combines ergonomic principles with a moving seat that keeps your body active while you work. You choose this type of chair when you spend many hours behind your computer and want to prevent physical complaints.

Why choose this specific variant?
With a load capacity of 150 kg, this chair suits a wide range of users and offers extra stability. The seat dimensions of 530 x 490 mm and the adjustable seat height of 430 to 510 mm make the chair suitable for different body heights. The 600 mm high backrest provides sufficient support for your lower and mid back.

Unique feature: three-dimensionally moving seat
What makes this chair special is the three-dimensionally moving seat that moves with your body. This technology keeps your muscles active even while seated, which promotes circulation and reduces tension. The movement is subtle enough not to be distracting, yet effective enough for you to feel the difference.

Practical adjustment to your workspace
The armrests are adjustable in three directions: height, width and depth, so you can find the perfect arm support regardless of your build or desk layout. For use on hard floors, you can order optional hard floor castors (article number 77400107) that protect your parquet or laminate from scratches.
