Sierra Sleep 8 Inch Chime Innerspring Mattress
Couldn't load pickup availability
The Sierra Sleep 8 Inch Chime Innerspring Mattress is for the back or stomach sleeper who wants a genuinely firm, springy coil bed at a doorbuster price, not a memory foam hug. It is the classic mattress your grandparents would recognize, built for the guest room, the kid's room, or the day a bed just needs to work without a big budget behind it.
Ashley builds this one, part of the 8 Inch Chime Innerspring series (model M695), around a 13-gauge Bonnell coil unit: hourglass-shaped steel coils tied together with helical wire, the same coil architecture that has supported budget mattresses for decades. Above the coils sits a high-density firming pad, then 2 inches of high-density quilt foam under the cover. That stack keeps the surface firm and even instead of letting it dip, so the mattress holds its shape at 8 inches total instead of sinking under weight.
How It Feels
Comfort level here is firm, full stop. There is no deep quilted layer working to soften the coils, so you feel support right under the surface rather than a slow sink. Because the coils are Bonnell, tied to each other across the whole bed, movement on one side carries further than it would on a pocketed coil or foam mattress, worth knowing if you are sharing the bed with a restless partner or a kid who tosses at night.
Setup
This mattress ships compressed and rolled inside a box. Carry the box into the room where it will be used, cut away the plastic wrap, and let it unroll. It fills out to full size within minutes and needs no assembly beyond that. A foundation or box spring is sold separately and required for proper support.
Who It Suits
- Back and stomach sleepers who want firm, even support under the hips and shoulders
- Anyone replacing a worn out coil mattress who wants that traditional feel back
- Guest rooms, kids' rooms, rentals, and other spots where a dependable, no frills bed matters more than plush comfort
- Allergy sensitive households, since every layer is made from hypoallergenic material
Side sleepers who want pressure relief at the shoulder and hip, or anyone who prefers a mattress that contours rather than pushes back, should look at one of our foam or hybrid beds instead. Firm coil support like this sits under you, it does not cradle you.
Sierra Sleep backs the 8 Inch Chime Innerspring with a 5-year non-prorated manufacturer's warranty, and it comes in Twin, Full, Queen, and King so it drops onto a frame you already own without a special order.
Feel matters more on a firm mattress than a plush one, since there is less foam to mask a bad fit. Come lie on this one at one of our Kentucky showrooms, in your own sleeping position, before you decide.
What makes this mattress different
Real steel coil support
A 13-gauge Bonnell coil unit, the classic coil architecture behind decades of traditional mattresses, gives this bed the springy, sleep-on-top-of-it feel that memory foam does not.
Firm from the first inch
2 inches of high-density quilt foam sits right under the cover, just enough cushioning to soften the surface without masking the coils underneath.
A firming pad that holds its shape
A high-density support pad rides between the quilt foam and the coil unit, keeping the surface even so it resists developing soft spots over time.
Ships flat, unrolls fast
The mattress compresses into a box for delivery. Unwrap it in the room where it will live and it expands to full size within minutes, no tools required.
Hypoallergenic materials
Every layer is made from hypoallergenic material, a straightforward plus for households managing allergies or sensitive skin.
A true low profile
At 8 inches tall, this is one of the shortest mattresses we carry, built for platform beds, bunk beds, daybeds, and any frame where a tall mattress would fit wrong.
Backed for 5 years
Sierra Sleep covers the 8 Inch Chime Innerspring with a 5-year non-prorated manufacturer's warranty against defects.
Built in every standard size
Twin, Full, Queen, and King are all available, so it drops onto a frame you already own without a special order.
A traditional coil mattress, built the way coil mattresses have always been built
The Chime 8 Inch Innerspring skips the deep comfort layers and hybrid coil systems found in Ashley's pricier lines and goes back to basics. From the top down: a quilted cover, 2 inches of high-density quilt foam, a high-density firming pad, then a 13-gauge Bonnell coil unit that runs the full length of the mattress.
Bonnell coils are hourglass shaped and wired together across the whole surface, the coil design that has supported American mattresses for generations. That connected structure is what gives this bed its springy, responsive feel, and it is also why motion from one side of the bed reaches the other more than it would on a pocketed coil or all foam mattress. The firming pad and quilt foam on top exist to even out that surface and take the hard edge off the coils, not to add plush give.
The result is 8 inches, total, of firm, no frills support: a mattress that does one job, hold you up firmly, at a price built for a second bedroom, not necessarily a primary one.

Back sleepers: firm, even coil support keeps the spine level instead of letting the hips sink, exactly what this mattress is built to do.
Stomach sleepers: a soft mattress lets the midsection sag and strains the lower back; the firm surface here keeps you level all night.
Kids' rooms and guest rooms: a dependable, no frills coil mattress that holds up under regular use without the price tag of a primary bedroom mattress.
Allergy sensitive sleepers: every layer is hypoallergenic, a reasonable pick for a household managing allergies.
Anyone who grew up on a coil mattress: if you want that classic bounce and firm push back instead of a foam hug, this is a straightforward way to get it back.
Probably not for you if: you are a side sleeper who needs cushioning at the shoulder and hip, or you share the bed with a partner who moves a lot at night; the connected Bonnell coils carry more motion across the surface than a pocketed coil or foam mattress would.

Frequently asked questions
How firm is the Sierra Sleep 8 Inch Chime Innerspring Mattress?
Firm, full stop. There is no deep comfort layer over the coils, just 2 inches of high-density quilt foam over a firming pad, so you feel the coil unit's support close to the surface rather than a slow sink. It is built for sleepers who want a traditional, springy coil feel, not a plush or contouring one.
What is inside the mattress?
From the top down: a quilted cover, 2 inches of high-density quilt foam, a high-density firming pad, and a 13-gauge Bonnell coil unit that runs the length of the mattress. It is a traditional innerspring build, not a foam or hybrid mattress.
Who is this mattress a good fit for?
Back and stomach sleepers who want firm, even support do best here, along with anyone furnishing a guest room, kid's room, or rental where a dependable coil mattress matters more than plush comfort. Side sleepers who need cushioning at the shoulder and hip usually feel more comfortable on one of our foam or hybrid mattresses instead.
Does this mattress sleep hot?
There is no dedicated cooling material built in, but Bonnell coils allow air to move through the mattress rather than trapping heat the way a deep memory foam layer can, so most sleepers do not find a firm innerspring like this one runs hot.
Will I feel my partner move on this mattress?
More than you would on a foam or pocketed coil mattress. The Bonnell coil unit ties every coil to its neighbors with helical wire, so motion travels across the surface instead of staying contained to one spot. If you share the bed with a restless sleeper, that is worth knowing going in.
What size options are available?
Twin, Full, Queen, and King. All four sizes use the same 13-gauge Bonnell coil build and firm feel; the only difference is the footprint.
Do I need a foundation or box spring?
Yes, a compatible foundation or box spring is sold separately and required for proper support. Mixing a mattress and foundation from two different brands can also affect warranty coverage, so ask our floor team if you are not sure your existing foundation is a match.
How is it delivered and set up?
The mattress ships compressed and rolled inside a box. Bring the box into the room where the mattress will be used, cut away the plastic wrap, and let it unroll; it expands to full size within minutes. No tools or assembly are required beyond that.
Does this mattress come with an at-home sleep trial?
No. Sierra Sleep mattresses like the 8 Inch Chime Innerspring do not include an at-home trial period. Because firm, traditional coil support feels different to everyone, our Kentucky showrooms are set up so you can lie on this exact mattress in your own sleeping position and know how it feels before you buy, not after.
