When do you choose this product?
When do you need an office stool without a backrest?
A stool such as the Topstar TEC 70 is ideal when you frequently switch between sitting and standing during your work. This type of stool gives you more freedom of movement than a traditional office chair and encourages an active sitting posture. Choose a stool if your workspace has limited room or if you regularly move between workstations.
Why these compact dimensions are perfect
With a seat size of 360 x 360 mm, this stool offers sufficient seating comfort without taking up much space. The height adjustment between 420 and 550 mm means you can adapt the stool to different desks and body heights. The compact size also makes this stool suitable for smaller workrooms or as an extra seat.
Sturdiness and comfort thanks to a clever combination of materials
The seat combines 88% PVC with 12% cotton and has an extra-thick padding for long-lasting seating comfort. The polished aluminium base offers stability up to a body weight of 110 kg, making the stool suitable for most users. The Toplift technology ensures smooth height adjustment without jerking.
Practical tip for your flooring
The stool is supplied as standard with safety twin castors suitable for carpets and soft floors. Are you working on a hard floor such as laminate or tiles? Then you can optionally order the hard floor castors (article number 70699950). These protect your floor from scratches and roll more smoothly over slippery surfaces.
