Experience the unmatched comfort of Technogel®, a premium medical-grade gel designed to lift your body into a feeling of weightless support. It cools before you get hot, helping maintain a comfortable sleep temperature throughout the night, while supporting without sinking or collapsing for proper spinal alignment. Proven to improve deep, uninterrupted sleep by up to 45%, Technogel® delivers a truly restorative sleep experience that feels as good in the morning as it does at bedtime.
The Technogel® Core Hybrid Mattress is designed for side, back, and combination sleepers who want the perfect balance of cooling comfort and responsive support. Its innovative construction provides gentle lift and reinforced center support right where your body needs it most—helping promote proper spinal alignment throughout the night.
At the heart of the mattress is the Technogel® CORE layer, an Italian-engineered, medical-grade gel that contours to your body while evenly distributing weight to relieve pressure points. Unlike traditional foam, Technogel provides supportive lift without the “sinking” feeling. Its naturally high thermal capacity also helps absorb and disperse body heat, creating a cooler, more comfortable sleep environment.
Beneath the gel layer, graphene-infused comfort foams add responsive cushioning and enhanced durability. A foam-encased pocketed coil system adapts to your body’s shape to provide targeted support, improved airflow, and long-lasting hybrid performance. Available in Firm, Medium, and Plush comfort options.
