Biostyle is a semi-rigid latex foam mattress. Thanks to its compact structure and the particular processes involved in its manufacturing, it offers rigid support, differentiated in 7 support zones. Biostyle is completed by a hypoallergenic and breathable thermal polyester fibre cover, on both sides, and a perimeter band of 3-space breathable fabric, removable on 4 sides to permit the ventilation of the internal structure by opening the mattress into two halves.
