The Diamond Technogel® Technology Estasii 3.0 Plush Foam Floor Sample Clearance Mattress is a plush memory-foam mattress built for side sleepers and combination sleepers. Diamond Mattress is family-owned and California-built — every model is hand-assembled in Chino with CertiPUR-US foams and OEKO-TEX natural fibers. At 12", it sits in the standard profile range — generous enough for adjustable bases yet still easy to sheet.
Hand-assembled in California with domestic steel coils and CertiPUR-US foams.
A breathable quilt and gel-infused top draws heat away so you don't wake up hot.
We deliver, set up in your bedroom, and haul away your old mattress — no extra charge.
A 3/10 firmness — soft enough to cradle hips and shoulders. Best for side sleepers under 200 lb.
Built for adaptive support and breathability. Every layer is hand-checked before it ships from our warehouse.
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.
