Dyonery 12" Cal King Memory Foam Mattress, Medium Firm, Cool Gel Cooling, Pressure Relief, Removable Fiberglass-Free Cover, CertiPUR-US Certified

Elevate your nightly rest with the Dyonery Gel Memory Foam Mattress, designed to balance plush comfort, reliable support, and year-round coolness for every type of sleeper. Built with a premium 5-layer construction¡ªfeaturing a breathable knitted outer cover, fiberglass-free flame-retardant inner layer, cooling gel-infused memory foam, high-density supportive base foam, and anti-slip bottom fabric¡ªthis mattress delivers a perfectly calibrated medium-firm feel that adapts to your body without sacrificing stability. The cooling gel memory foam actively dissipates excess heat and promotes airflow, eliminating the stuffiness of traditional foam mattresses to keep you at a consistent, comfortable temperature through every season. Meanwhile, the responsive memory foam gently contours to every curve of your head, neck, shoulders, back, waist, hips, and legs, evenly distributing your weight to relieve pressure points and reduce morning aches and pains. The high-density support core prevents sagging and maintains proper spinal alignment, making it ideal for side, back, and stomach sleepers alike. Safety and convenience are woven into every detail: the mattress is double-certified by CertiPUR-US and OEKO-TEX Standard 100, meeting strict standards for safety, durability, and environmental responsibility, and it is completely fiberglass-free for peace of mind. The removable, zippered outer cover is fully machine-washable for easy upkeep, while the anti-slip bottom keeps the mattress securely in place on any bed frame. Delivered compressed and rolled in a compact box, it¡¯s simple to transport and set up by just one person¡ªsimply unbox, unroll, and allow 24-72 hours to fully expand to its original shape. Compatible with box springs, slatted bed frames, platform beds, and metal bed grids, this mattress is the perfect upgrade for restful, uninterrupted sleep every night.
