The offer applies to an extremely functional item A 200x80x18cm polyurethane foam mattress in an elegant cover! This is an innovative design on a European scale, developed by our engineers and registered in the Patent Office!The quattro model features four firmness levels – from the soft H2 side, through the medium-firm H3, the firm H4, and the very firm H5. Depending on how the mattress is positioned and which side you choose, the desired firmness level will be achieved. One side is made of firm, dense polyurethane foam with a reinforced cell structure, while the other is a layer of soft, high-resilience (HR) foam with an open structure. It is perfect for both home use and in hotels or guesthouses. When shopping online without the opportunity to test, this is an ideal solution, as one of the options will always be right for you.This mattress is also an ideal choice for children and teenagers, as they grow and their weight changes, they can be rotated and adjusted to their current needs.Highly elastic (HR) foam has a smooth texture and irregular structure, which makes it characterized by high point elasticity and dynamic behavior during load changes. This provides excellent body support, guaranteeing an ideal sleeping position and maximum comfort. It is highly resistant to stretching and intense crushing and quickly regains its shape. Thanks to its open-cell structure, it ensures good ventilation and air permeability.The whole is complemented by an elegant, quilted, membrane cover made of microfiber mattress fabric, with a four-way zipper for easy removal and dressing.We spend 1/3 of our lives in bed, so let's make sure it's a time of comfort, relaxation, and pleasure!We always provide two values that characterize polyurethane foam. The first indicates the mass in m3 (the higher the value, the denser the foam and the mattress will retain its shape longer and allow for comfortable sleep). Only the second value indicates the firmness (the higher the value, the firmer the mattress). Remember that we pay for 1 kg of foam in m3, so the T30 mattress is 20% more expensive in production than the popular T25 (if this is true and T25 is not just an average of T2030 foam, which is under no circumstances suitable for a mattress). In REM-Sen, higher quality does not go hand in hand with a higher price of the mattress!Only with REM-Sen mattresses will your SLEEP reach the R E M phase!
