Mattress Description

Experince Technogel Technology 

Technogel® is a bio-compatible material that adapts to body contours like water while providing solid support. It alleviates pressure, maintains spinal alignment, and allows natural movement, enhancing sleep by up to 45%. Its conductivity and density pull away heat, absorbing up to 10 times more heat than foam for deeper sleep. Certified by Oeko-Tex and approved for medical use, Technogel® is non-toxic, hypoallergenic, odorless, pressure-relieving, cooling, and free from plastics, liquids, and oils, offering a soft and supportive rest.
