The Zinus Calm is a 10-inch tight-top memory foam mattress in a medium feel, with a gel-infused top layer meant to pull heat away and green tea and charcoal in the foam. It ships rolled in a box and carries a 10-year warranty. It suits shoppers who want an all-foam bed with some cooling for a guest room, kid's room or a first apartment. Against pricier gel foams it gives up edge support and a removable cover, and owners report it sleeps warm for some and softens over time.
