Product Details
If you like the familiar support of a traditional coil mattress but want a softer top layer to help you settle in, the Mattress Firm Chime 12-inch Hybrid Mattress brings those two feels together in one straightforward design. Its hybrid innerspring build contours to your body while keeping a supportive, steady sleep surface.
Comfort layers include high density foam for the firmer feel many sleepers prefer, plus gel memory foam designed to support your lower back. It is a practical choice for everyday sleep, whether you are refreshing a guest room or upgrading from an older mattress that no longer feels as supportive.
Setup is simple because it arrives as a Mattress in a Box. Move it to your room, remove the plastic, and unroll it into place. A foundation or box spring is available and sold separately. We make sleep easy.

Caution
The power foundation has many moving parts. Caution must be used in operation. Children should not be allowed to play on or operate the power foundation. Always leave the power foundation in the flat position, and keep hands, fingers, and body parts away from the mechanism.
Ashley reserves the right to refuse service and invalidate these Limited Warranties when, upon inspection, the mattress or foundation is found to be in an unsanitary condition or when product failure is due to causes other than defective workmanship or materials. Please refer to the "Mattress & Foundation Care Instructions" section of this Limited Warranty for proper mattress and foundation care.
MATTRESS & FOUNDATION CARE INSTRUCTIONS:
DO:
- DO give your new mattress set time to "air out’ upon removal from its plastic packaging. Dispose of all plastic packaging as soon as possible.
- DO carry your mattress fiat on its side. It’s easier to handle and you’ll be less likely to damage the mattress.
- DO keep your bedding clean. We suggest using a mattress pad or mattress protector, especially if children use the bed.
- DO replace the old foundation when purchasing a new mattress. An old foundation may not provide sufficient support. It may appear that your new mattress is sagging when it is really the foundation, which supports the entire mattress.
- DO use an appropriate frame and center support for queen and king-size sets. Using the right support frame will ensure that your warranty remains in effect.
- DO allow your memory foam mattress to warm to room temperature. The memory foam is temperature sensitive and will soften when it is warm.
DON’T:
- DON’T PLACE YOUR MATTRESS NEAR OPEN FLAME OR EXPOSE TO FIRE. THIS MATTRESS IS NOT FLAME OR FIREPROOF, AND CAN IGNITE AND/OR BURN IF EXPOSED TO OPEN FLAME OR FIRE. WHEN IGNITED, SOME BEDDING MATERIAL CAN BURN RAPIDLY AND EMIT SMOKE AND HAZARDOUS GASES.
- Don’t smoke in bed. This mattress is manufactured as required by Federal law to resist, but not necessarily eliminate, ignition by smoldering cigarettes.
- Don’t let anyone stand or jump on your mattress or foundation. It was not built for that kind of weight concentration or abuse.
- Don’t allow your mattress to get wet because some of the upholstery materials may compress. Protect it from water or other liquids.
- Don’t remove the law label or tag at the end of your mattress. This label serves as a means of identification to establish your right to the Limited Warranty.
- Don’t use dry cleaning fluid of any type on your mattress. These chemicals will damage some of the construction materials and will void the Limited Warranty.
- Don’t place pillow-top side of mattress on bottom.

How long does a mattress last?

How do you clean a mattress?
Cleaning a mattress is a simple step-by-step process. First, remove all bedding and covers to wash separately. Then, use the upholstery attachment on your vacuum cleaner to thoroughly vacuum the entire surface of the mattress, paying special attention to seams, crevices and edges. Then, spot-clean stains where needed using different solutions depending on the stain type. Once the mattress is clean, sprinkle a generous layer of baking soda over the surface to deodorize. After a few hours (ideally overnight), vacuum the mattress thoroughly to remove all residue.
What type of mattress is the Chime 12" Hybrid?
It’s a hybrid innerspring mattress that combines a traditional coil system with foam layers for a blend of contouring and support.
What creates the supportive feel in this mattress?
The high density foam layer is designed to add the firmness and support many sleepers prefer, working alongside the coil system.
How does it support the lower back?
The gel memory foam layer is designed to provide restorative support for your lower back as you settle in.
How does setup work when it arrives?
This mattress arrives in a box. Bring it to your room, remove the plastic wrap, and unroll it for quick, easy setup.
Do I need a foundation or box spring?
A foundation/box spring is available but sold separately, so you can choose the setup that works best for your bed frame.
