The Chime 12" Hybrid is a twin mattress in a box from Signature Design by Ashley that pairs a traditional innerspring coil unit with high-density foam and a gel memory foam layer. It is sold as an ultra plush model, so it suits sleepers who want a soft, contouring surface over coil support rather than a firm bed. It ships rolled and vacuum-packed, so it works for tight rooms and stairs where a rigid mattress would not fit. Against all-foam boxed mattresses, the coil core gives it more bounce and edge response; against premium hybrids, it is a simpler build with fewer comfort layers. A foundation or box spring is not included.
