The unique combination of four comfort zones ensures the perfect sensation when you sit down.


  • The pocket-sprung cushion is the basis: The individual springs are enclosed in little pockets. This achieves good firmness. A pocket-sprung cushion exhibits good point elasticity when pressure is applied. In other words the seat yields exactly at the point of body contact, which prevents sagging
  • This is topped by a 15 mm layer of durable cold foam with good elastic properties
  • Then there is another softer layer of 10 mm cold foam
  • The fourth comfort zone is made of 10 mm moulded foam with a high restoring force and elasticity for exceptional sitting comfort and a particularly soft sensation on sitting down

When these four comfort zones interact, the body weight is evenly distributed without pressure points. The resulting pressure relief is gentle on the spinal discs, pelvic bones and muscles, as well as improving the circulation. Sit comfortably for long periods.
