Our bed, where we spend most of our day, is very important for our health. Starting a new day ready, rested and happy is much easier with a quality mattress. Our mattress is produced with hercules spring technology that improves sleep quality. The top layer is woven from knitted fabric and the bottom layer is woven from sweatfree jacquard fabric. It can be used on both sides. One side knitted fabric and the other side jacquard fabric is used. Ventilation capsules are used on the side borders.
