When do you choose this product?
When do you need an ergonomic office chair?
An office chair with ergonomic support is essential if you work at a desk for several hours a day. This Topstar Open Base 10 combines comfort with professional functionality through the lumbar cushion and the relax point synchronous mechanism. The mesh fabric in the backrest ensures optimal ventilation during long working days.
Why choose this size and version?
With a seat width of 480 mm and a seat height adjustable between 420-550 mm, this chair suits average to taller people. The 600 mm high backrest provides sufficient support for the entire back. The aluminium five-star base with safety castors makes this chair suitable for intensive office use.
What does the load capacity of 110 kg mean?
The maximum load capacity of 110 kg makes this office chair suitable for most users. This specification indicates that the chair withstands regular and prolonged use without loss of quality. The stable construction with aluminium base supports this weight without any problems.
Practical considerations for your workspace
When choosing, pay attention to your floor type: the standard castors are suitable for carpet and soft floors. For hard floors such as laminate or parquet, you can order optional hard floor castors (article number 70699952). The seat, made of 80% cotton and 20% polyurethane, offers a good balance between comfort and durability, while the shaped seat surface promotes a natural sitting posture.
