A 12-inch memory foam mattress offers a balanced combination of cushioning, support and pressure relief for a comfortable night’s sleep. Its thicker profile typically includes multiple layers of foam designed to contour to your body, help distribute weight evenly and reduce pressure around the shoulders, hips and lower back. Compared with thinner memory foam mattresses, a 12-inch design may provide more room for comfort layers while maintaining the supportive feel sleepers need. Depending on the construction, these mattresses can include cooling gel memory foam, breathable covers, responsive transition foam and a durable support core to promote proper spinal alignment for side, back and combination sleepers. A 12-inch memory foam mattress can be an excellent choice for couples and anyone looking for a supportive mattress with the conforming feel memory foam is known for. The foam can help absorb movement across the sleep surface, so a partner’s tossing and turning may be less noticeable during the night. Many 12-inch memory foam mattresses are also available as a mattress in a box, making delivery and setup more convenient. As you compare options, consider firmness, cooling features, edge support, sleep position and the mattress foundation required for proper support. Finding the right 12-inch memory foam mattress can make it easier to get better zzz's and wake up ready to live well.
