This office chair supports your back exactly where needed, thanks to the built-in lumbar support and the moving contact mechanism. Comfortable seating from 420 to 550 mm in height, and with optional armrests you can make it exactly to your liking.
When do you choose this product?
When do you need an office chair with lumbar support?
If you work at your desk for long periods every day, an office chair with integrated lumbar support is essential for your spine. The TOP PRO 1 supports your lower back and helps you maintain a healthy working posture. Thanks to the permanent-contact mechanism, you always stay in contact with the backrest, even when you move or lean back.
Why this size and load capacity?
With seat dimensions of 460 x 450 mm, this chair offers comfort for most body types. The load capacity of 110 kg makes it suitable for a wide range of users. You can adjust the seat height between 420 and 550 mm, so you can perfectly match the chair to your desk and height.
Ergonomic moulded seat for long-lasting comfort
The ergonomic moulded seat distributes your body weight evenly and prevents pressure points. The 100% polypropylene material is wear-resistant and easy to keep clean. The backrest has a height of 450 mm and provides support up to your mid-back, while the integrated lumbar support respects the natural curve of your spine.
Practical upgrade options
You can later upgrade the chair with optional armrests (type E, reference 70609900) if you want more arm support. For use on hard floors, special hard-floor castors are available (reference 70699950) that protect your parquet or laminate from scratches.
