Omne Sleep Copper Recovery Memory Foam Mattress California King 14 Inch, Cooling Gel Memory Foam, Medium Feel, Pressure Relief, Fiberglass Free, Bed in a Box
- CALIFORNIA KING 14 INCH MEMORY FOAM MATTRESS. The long-and-plush combo. 84 inches of length for tall sleepers, plus the 14-inch profile for softer conformance. If you've been sleeping on a 10 or 12-inch mattress and waking up sore, this is the kind of upgrade people notice in week one.
- SLEEPS COOLER THAN STANDARD MEMORY FOAM. A specialty cover woven with heat-pulling fibers sits over a comfort layer that absorbs and redistributes body heat instead of trapping it. If you wake up hot at 3am, sweat through sheets, or flip your pillow constantly, this is the feature that addresses it.
- MEDIUM FEEL — THE MOST VERSATILE FIRMNESS. Soft enough for side sleepers to sink in at the shoulders and hips. Firm enough for back and stomach sleepers to feel supported, not swallowed. Couples with different preferences typically land here. If you don't know what firmness to pick, pick this one.
- 14 INCHES OF ENGINEERED LAYERS, NOT FILLER. Taller doesn't mean better unless the inches do work. Every layer here has a distinct job: the top conforms and cools, the middle transitions, the base supports. Most budget mattresses get thickness from a single slab of polyfoam. This one doesn't.
- 100-NIGHT TRIAL AT HOME, 10-YEAR WARRANTY. Sleep on it for 100 nights before committing. Ships compressed in a bed-in-a-box and expands in 24 to 48 hours. Made in the U.S. by a family-owned manufacturer with 20+ years in the sleep industry. Not drop-shipped, not white-labeled.
