RANCHO DOMINGUEZ, Calif. (December 17, 2025) – Diamond Mattress and bedding retail giant Sit ’n Sleep have extended their successful Technogel® and Cloudtech collaboration with a refreshed merchandising strategy and introduction of eight new mattresses that will serve as the first phase of a national rollout debuting at the Las Vegas Market next month.
The new four-bed Technogel® mattress collection delivers unmatched lift, cooling and support, made possible by the brand’s patented medical-grade gel material, which moves in 3 dimensions to adapt to the body’s unique form. All four models—Favola, Estasi, Armonia and Sereno—feature advanced cooling technologies, including phase-change materials, graphene-infused foams to provide thermal regulation, adaptive support and long-term durability. The collection is available in multiple comfort options and profile heights.
The newly remerchandised Cloudtech program builds on the strong performance of the original collection, which became a Top 10 program for Diamond within its first 90 days at Sit ’n Sleep and exceeded expectations for both companies. The two Southern California leaders have continued to grow the program through shared investment in innovation, training and in-store performance.
This new Cloudtech lineup includes two Cirrus models, an all-foam design featuring the brand-new Technogel core support layer, and two Stratus models, a quilted top design featuring pocketed coil system and foam-encased edge support. Offered in 12-inch and 15-inch heights, the collection is GreenGuard Gold certified, Certi-PUR certified and made in the U.S.
Diamond Mattress officials highlighted the Technogel core topper featured in the Cirrus models. Developed in close collaboration with the Technogel engineering team over several months, this next-generation support layer offers a lighter-weight, competitively priced support layer designed to deliver cooling, weightless comfort and targeted pressure relief at the core of the mattress and the core of the sleeper.
“The Sit ’n Sleep team has long excelled with Cloudtech and Technogel, and they continue to demonstrate high confidence in presenting advanced cooling and pressure-relief technologies to customers,” said Shaun Pennington, Diamond Mattress CEO. “Extensive testing, shared feedback loops and collaborative development have shaped the refreshed line and contributed to its elevated aesthetic and updated performance story.”
The Sit ’n Sleep launch establishes the foundation for Diamond’s new nationwide Cloudtech and Technogel programs. Retailers can experience the full assortment for the first time in the Diamond showroom B-975 at the Las Vegas Market beginning January 25, 2026.
