Dyonery 8" Queen Flippable Mattress(80 X 60), Dual Firm/Extra-Firm for 2 Sleep Feels, Detachable Cover, HD Foam eases backache, CertiPUR-US Certified

Our 8-inch & 10-inch Queen/King size flippable gel memory foam mattress is built with a scientific three-layer foam system to upgrade your nightly rest entirely. The top comfort foam layer offers soft, skin-friendly breathability for gentle wrapping; middle high-density blue gel memory foam absorbs and dissipates surplus body heat while closely hugging body contours to disperse pressure points and protect spinal alignment; the sturdy bottom support foam delivers long-lasting stable bounce that avoids collapse even after years of frequent use. Thanks to its practical two-sided reversible design, this mattress comes with two different sleep feels: the cooling gel side prevents overheating for heat-sensitive sleepers during hot summer, and the extra-firm supporting side relieves back pain via strong spinal support. Equipped with a full-zip removable, machine-washable and fiberglass-free outer cover, it gets rid of tedious spot cleaning and stays hygienic with regular washing. Every component passes CertiPUR-US and Oeko-Tex Standard 100 safety inspections, completely free of harsh hazardous substances to serve infants and expecting mothers safely. Constructed with dense durable foam, our mattress is anti-deformation and sag-proof for long-term consistent support. It arrives vacuum compressed in a handy box for effortless delivery, only needing 48 hours of natural expansion after unboxing to finish installation, a perfect practical bedding option for improving your sleep quality.
