The NightyNight is an 8-inch twin memory foam mattress sold compressed in a box, with a cooling gel and green tea infused foam core and a removable, washable knit cover. It targets side, back and stomach sleepers who want a medium-firm feel without spending much. Against thicker 10- to 12-inch foam mattresses it offers less cushioning and a shorter expected lifespan, and its cooling claims are modest for a foam bed. Owners rate it well overall, with comfort and easy setup standing out and durability over years the main doubt.
