The Chime 12" is a memory foam mattress in a box from Signature Design by Ashley, sold here in a twin. A thick memory foam layer sits over a firm support foam base, and the brand calls the feel ultra plush. It suits shoppers who want a soft, contouring bed for a guest room, kid's room or small bedroom and who don't mind a mattress that arrives rolled and needs time to expand. Against other bed-in-a-box twins, it leans softer than most all-foam rivals and has no coils, so it isolates motion but offers less bounce and edge support.
