The 4.5-inch sofa bed mattress is comprised of 2 layers of memory foam, the top layer of plush memory foam provides plush comfort and pressure relief and the bottom layer of dense foam provides orthopedic support and ensures the longevity of the sofa mattress. Memory foam reacts to body heat and conforms to the body's curves, aligning the spine during sleep. This mattress will fold up inside your sofa and unfold as easily as a spring sofa mattress would. You could also use this sofa mattress as a bunk bed mattress, a boat mattress, an RV mattress or even as a mattress topper.

Why Upgrade to Memory Foam?
A memory foam mattress can support each part of the body evenly and individually. Memory foam slowly and automatically adjusts to your body weight and temperature. In addition to the slow, conforming response, memory foam offers complete, luxurious and stress-free support. This can allow the spine to stay in a neutral position. Should you move during the night, your partner is never disturbed due to the lack of reciprocal movement between sleeping partners. Additionally, when you do move in bed, memory foam gently fills in and reshapes itself to your new sleeping posture, cradling every part of your body.

How it Works For a Better Night's Sleep

Starting with the top layer of 2-inch breathable memory foam that works with the support layer providing you with the ultimate sleeping experience. The 2.5-inch support base layer maintains the strength and effectiveness of the layers. The two layers work together to bring you the relaxation you crave and the ultimate sleeping experience. Covered with a beautifully detailed knit cover for breathability, this elegant cover moves with you. The 4 way stretch conforms to your body for comfort working with the top layer of memory foam to optimize its contouring properties.
