Overview
Signature Design by Ashley builds the Chime as a twelve inch hybrid that layers gel memory foam, support foam and soft quilt foam over individually wrapped coils. It ships compressed and expands after unboxing.
Wrapped coils with perimeter rows add edge support and reduce motion transfer, and the foam layers soften the surface. It arrives compressed and needs time to expand, and no trial or warranty detail is given.
Who it's for
Couples or sleepers who want medium firm support and low motion transfer on a king frame are the target. Shoppers needing a foundation in the same order, a firmer or softer feel, or warranty terms should look elsewhere.
Pros and cons
- Medium firm feel
- Wrapped coils reduce motion transfer
- Perimeter coil rows add edge support
- CertiPUR-US gel memory foam
- Foundation sold separately
- Warranty terms not listed
- State recycling fee may apply
Performance notes
Individually wrapped coils move independently, which limits motion transfer, and two perimeter rows firm up the edges. The foam layers on top, from gel memory foam to soft quilt foam, set the feel. The mattress expands after unboxing and needs time to reach full height.
