When do you choose this product?
What does this product do?
The Topstar Sitness 15 is an office chair with Body-Balance Tec technology that helps you stay active while sitting. Thanks to the special Fitness-Orthositz function, you move subtly with the chair, which improves your posture and activates your muscles during long working days.
Why this size and this variant?
With seat dimensions of 480 x 440 mm and a height adjustment range of 430 to 540 mm, this chair suits most workstations and body types. The 110 kg load capacity makes it suitable for a wide range of users, while the included armrests provide extra support for your arms and shoulders.
How does the Body-Balance Tec technology work?
The Body-Balance Tec system ensures that the seat moves slightly with your body, keeping your core muscles activated. This prevents the stiffness that arises with traditional chairs and helps you stay energetic while working. The Permanentkontakt mechanism keeps the backrest in constant contact with your back for continuous support.
Practical considerations for your workspace
The breathable mesh backrest, in the same royal blue colour as the seat, prevents overheating during intensive desk work. For use on hard floors, you can optionally order special hard floor castors with article number 70699950. The 100% polypropylene upholstery is durable and easy to keep clean, which is important for daily intensive use.
