The Otello 35 Density Mattress is a high quality product with FIREPROOF poliurethan. The 35kg elastic and non-deformable polyurethane sheet is covered with fabric quilted with hypoallergenic polyester and stretch fabric. The patented Adaptive treatment makes it thermoregulated and more comfortable in every season. This results in a comfortable, resistant and non-deformable bed surface. The thickness can vary from 13 to 20 centimeters in order to meet different needs and adapt to the different versions of the Otello mechanism. It is an ideal mattress for daily use. The quilting on two sides makes it reversible. The band is produced in non-slip and anti-tear 3D latex fabric. The mattress is packed with heat-welded polypropylene. The same mattress is also available in the version quilted on one side only with anti-slip and anti-tear 3D latex fabric, ideal for products inserted inside metal mechanics.
