This Brentwood Home mattress provides a medium-firm feel. The 2.5-inch layer of gel infused memory foam responds to your body’s individual shape, weight, and temperature. It adjusts its shape to provide precise support, keeping your spine in alignment while relieving discomfort at pressure points in areas like your hips and shoulders. The infused gel and the ventilated airflow layer evenly disperse heat through the mattress to prevent hot spots that lead to tossing and turning. Our special blend of memory foam actively responds to your movements, allowing you to move freely around the bed without experiencing the quicksand effect. A solid support base absorbs your weight to dampen motion transfer and prevent noise. The mattress is finished in a removable wool-lined zipper cover that stretches in all directions, allowing you to enjoy maximum pressure relief. The wool lining resists odors while it wicks away moisture and regulates body temperature by creating micro-climates. This means that you stay cool in the summer and warm in the winter. The safety of your family is important to us so we only use CertiPUR-US certified foams that are free of flame retardants, formaldehyde, heavy metals, and phthalates. We offer a 25 year warranty as a guarantee of quality. You will be protected from manufacturing defects and premature sagging. We compress and roll our mattresses for easier shipping and setup.
