The Casper mattress's Zoned Support Layer provides a firmer support for your back and distributes your weight evenly. The cooling cover is made from knit and polyester, which distributes your weight evenly. This mattress is great for back and side sleepers. If you need to sleep on your stomach, you can opt for the Nectar Memory Foam Mattress instead. This type of mattress is recommended for stomach and back sleepers because it allows your back to stay straight.
