Overview
A 12-inch queen memory foam mattress from Signature Design by Ashley's Chime line, shipped compressed in a box. It pairs a contouring memory foam top layer with a firmer support foam base and expands to 60 inches wide by 79.5 inches deep once unboxed.
The listing leans on CertiPUR-US certification, which covers foam content, emissions and durability testing rather than any comfort claim. It is worth noting this mattress ships without a foundation or box spring, so a compatible platform bed, adjustable base or existing foundation is needed before it arrives.
- 12-inch profile, queen size
- 60" W x 79.5" D x 12" H expanded
- Stretch knit cover
- CertiPUR-US certified foam
Who it's for
Suits a queen bedroom needing a medium-firm foam mattress at a mattress-in-a-box price point, including guest rooms and primary suites being furnished from scratch. Sleepers who specifically want a soft plush feel or an innerspring mattress should look elsewhere, since this is built around a firmer support layer.
Pros and cons
- Compatible with platform beds and adjustable bases
- CertiPUR-US certified foam
- Compact box shipping simplifies delivery
- Foundation or box spring sold separately
- Firmness runs medium firm, not plush
- Needs time to expand after unboxing
Performance notes
The construction layers a contouring memory foam comfort layer over a firmer support foam base, which is the combination the brand credits for reducing motion transfer between partners. Compression packaging means the mattress needs time after unboxing to fully expand before it reaches its intended firmness and loft.
