The flät FLAT LUX is an orthopedic mattress designed to provide balanced support through a 5-zone pocket spring system. This core is specifically engineered to adapt to the different needs of your head, shoulders, back, hips, and feet, ensuring your spine remains properly aligned throughout the night. For added comfort, the mattress features a combination of green tea memory foam and high-density polyurethane foam, which work together to relieve pressure and isolate motion so you aren't disturbed by a partner's movements. A latex layer adds necessary elasticity and improves ventilation, contributing to a light, floating sensation while you sleep. With a medium firmness rating of 4.5, it balances softness and stability. Measuring 180 x 200 x 32 cm, this model includes a 7 cm foam edge support that prevents sagging at the sides, effectively increasing the usable sleeping surface. This makes it a practical choice for those who appreciate a supportive yet breathable bed that maintains its shape and stability.
