The Irisette Fehmarn pocket spring mattress is a high-quality mattress featuring a 7-zone spring core and breathable comfort layers on both sides, approximately 4 cm in height, for optimal body adaptation. The construction and ergonomic 7-zone division provide extremely high point elasticity while ensuring effective pressure relief. The shoulders are effectively relieved, and the pelvis is gently supported, making it ideal for side sleepers. The mattress guarantees quick moisture transport and prevents heat buildup. With a 4-sided, detachable zipper, the cover can be removed and washed at up to 60 °C. Four practical turning handles make it easy to rotate and flip the mattress.
