The Queen-Sized Ashley Chime Elite 12-Inch Memory Foam Firm Mattress is perfectly designed for back and stomach sleepers alike, with a comfort rating of 3.5. However, I wouldn't recommend this mattress for side sleepers, who typically require a softer sleeping experience.

The Queen-Sized Ashley Chime Elite 12-Inch Memory Foam Firm Mattress uses multiple foams for support, including Green Tea Support Foam, Gel and Charcoal Infused Memory Foam, and Green Tea Ventilated Foam Technology. The Gel and Charcoal Infused Memory Foam provides outstanding pressure relief and much-needed durability, while the Green Tea Ventilated Foam Technology serves as a natural antioxidant to maintain freshness and the Green Tea Support Foam offers an additional layer of comfort. These foams are each exceptional in their own right, but create an unbeatable sleeping experience when put together.

In addition to the multitude of other features included in this mattress, the Queen-Sized Ashley Chime Elite 12-Inch Memory Foam Firm Mattress has a CertiPUR-US Certification. This certification proves the mattress has met the expectations of all Ashley foams through independent testing.

Finally, the Queen-Sized Ashley Chime Elite 12-Inch Memory Foam Firm Mattress has a Micro Cool Technology Cover. This cover assists in keeping your mattress regulated in terms of temperature, working to eliminate tossing and turning throughout the night.

In conclusion, the Queen-Sized Ashley Chime Elite 12-Inch Memory Foam Firm Mattress is guaranteed to impress back and stomach sleepers alike. For a sleeping solution that will put your current mattress to shame, consider adding the Queen-Sized Ashley Chime Elite 12-Inch Memory Foam Firm Mattress to your home furniture collection today.
