Dyonery - Medium - Extra Firm Flippable Mattress Queen, 12 Inch High Density Bed-Mattress in Box - White

Hard support, precise waist protection: With a dual-layer support structure of bamboo charcoal sponge and gel cold-sensing sponge, the slightly hard feel can securely hold the waist and hips, fitting the body curve and alleviating back and waist pain. Slow recovery memory foam: The green tea memory foam layer can slowly rebound, dispersing body pressure. When lying down, the shoulders, neck, waist, hips, and ankles can all receive uniform support, and there will be no collapse when turning over.

Gel foam + bamboo memory foam mattress (fiberglass-free), 2-sided cover. Choose medium/extra firm for back pain relief, low motion transfer—enjoy luxurious deep sleep.

Designed for maximum firmness, this mattress provides strong spinal support and helps relieve back and waist pain caused by insufficient support. It balances comfort and stability, making it ideal for those who prefer a firm sleeping surface. A great gift for the whole family.
