Aware of the destructive effects of plastic waste dumped into the planet's waters, a problem with a major impact on environmental pollution, we decided to use a textile material made of 50% recycled polyester fibers in the OCEAN'S DREAM mattress, which would contribute to the conservation of natural resources and the maintenance of a less polluted aquatic ecosystem. The textile material contains a special fiber, obtained by recycling plastic waste, recovered largely from the aquatic environment. From this fiber, brand manufacturers in the textile industry have made dedicated materials for mattress covers, which, in addition to a comfortable and restful sleep, give people the satisfaction of making an important contribution to protecting the environment! Durable and more environmentally friendly than virgin polyester fiber. The fiber obtained by recycling plastic waste has the same characteristics as virgin fiber such as: elasticity, wear resistance, moisture absorption and color durability. In addition, recycled fiber is much more durable and environmentally friendly than virgin polyester fiber. The OCEAN'S DREAM mattress can be used on both sides: summer + winter, with the same degree of comfort thanks to the integrated MEMORY SOFT TOUCH foam topper. Both sides are quilted with natural materials specific to the season, such as: cotton for the summer side and wool for the winter side. The core of the OCEAN'S DREAM mattress is made with Pocket-Spring technology (individually wrapped springs) an advantage that contributes substantially to maintaining the health of your body. The mattress should be placed on a flat and continuous surface. We recommend flexible base only if the distance between the slats is not more than 5 cm. SPECIFICATIONS Technical data.
