24 hour chair Svenstol® S6

Is it the same for you? You get into your car and immediately feel relaxed - even on long journeys. This great feeling is the result of research into factors such as the shape and structure of cushioning, foam density and cell structure, cover material and cushioning technology.

With our comfortPlus cushioning we have adapted this knowledge for the ergonomic requirements of screen work. The maximised contact surface enables improved weight distribution and reduced muscular tension: ideal for periods of focussed work.

When we sit down, we don't move around enough – and this lack of movement places excessive strain on our muscles, which are not designed for long-term periods of static activity. This can cause: Muscle strain, pain, a hunched posture and a premature loss of muscular strength. The solution: active sitting. The activePlus mechanism encourages increased movement. It activates the muscles, improves circulation and ensures that the user regularly makes that important switch between active and passive postures.

Large recline angle

Lean back and see things from a new perspective – and relieve your intervertebral discs and muscles with a potentially record-breaking 44-degree recline angle!

sitting comfort


A comfortable sitting position reduces pressure points, prevents strain and helps you stay focused for longer. ComfortPlus optimises the distribution of pressure when you're in a seated position: From its shape, surface texture, density, hardness and cell structure, to the spring and cushioning characteristics of the ergonomic cold foam, every aspect of the cushioning is designed to provide unrivalled comfort. The maximised contact area ensures optimum weight distribution for comfortable sitting.

Comfort headrest

Your neck bears the weight of your head all day long. If you sit for long periods of time, your shoulder and neck muscles can start to feel the strain, which can often result in pain and muscular tension.

Our comfort headrests provide the support you need while seated; simply adjust the height, tilt and depth of the cushion. Unlike the majority of other headrests on the market, our comfort headrest can be adjusted to support your head in any position, providing noticeable relief for your neck and shoulders.

Changing postures, extreme positions and heavy loads – our 24-hour chairs are specially designed in steel to satisfy the specific challenges of around-the-clock use.

6-legged base

To create the perfect 24-stability hour chair, all components must be designed with ultimate comfort and stability in mind. With six supporting legs, the base lays the foundations: The additional arm reduces the specific load on the base and rollers by 20%, making the Svenstol® surprisingly manoeuvrable – in spite of its size. The stable base also ensures that the chair is highly resistant to tipping, even in extreme positions. In conjunction with the supporting elements, frame and high-quality mechanics, your sitting position is active and safe.

The guarantee is valid in Germany, Austria and Switzerland, Sweden, France, The Netherlands, Belgium and Luxembourg and applies to all parts and all costs connected with repair, including transport or call-out charges.
