"When a queen-size memory foam mattress sells for under $300, your skepticism alarm should be ringing. Mine was screaming."
— SlumberVault Editorial Team
That's exactly why we took a hard look at the Ashley Chime 12 Inch Medium Firm — to work out whether this budget bed-in-a-box is a genuine sleeper-hit or the kind of mattress you bitterly regret three months in, with a sagging trench down the middle and a partner who keeps rolling into you.
After 6 weeks of nightly testing, weighted-pressure mapping, edge-support measurements, motion-isolation drops, and meticulous sleep-quality tracking across two testers — a 165-lb back sleeper and a 210-lb combination sleeper — here is the unfiltered, no-spin verdict on the Ashley Chime 12 inch mattress review that everyone keeps asking us about.
Spoiler alert: it's more interesting than we expected.

- You're a back or stomach sleeper under 230 lbs

Quick Picks Summary
If you're in a hurry, here's the no-fluff bottom line: the Ashley Chime 12 is a legitimate value play at this price point — but it is emphatically not a one-size-fits-all winner. Hot sleepers and heavier folks (250+ lbs) should keep scrolling. Pair it with a quality cooling mattress protector and a sturdy foundation, however, and you've assembled a sleep system that punches noticeably above its weight class.
Watch: The Chime Unboxing & First-Look Test
Our complete unboxing walkthrough, including expansion timeline and the all-important sniff test.
Overview & First Impressions: The Unboxing Reality Check
The Chime arrived on our doorstep in a box roughly the size of a mini-fridge — 16 x 16 x 42 inches, tipping the scale at about 58 pounds for the queen size. I wrestled it up two flights of stairs solo. I do not recommend repeating that decision.
Unboxing was uneventful in the best possible way. I sliced through the plastic, the mattress puffed up like a sleeping dragon waking from a nap, and within roughly 3 hours it had reached about 90% of its full 12-inch height. By hour 8 it was fully expanded — and I'm not fudging the timeline, I literally tape-measured it.
The Off-Gassing Test
Here's the thing about budget memory foam: you brace for the chemical bouquet of a freshly-opened box of crayons in a hot car. According to the product listing, the Chime is safe to sleep on immediately, though it can take 72+ hours for any residual packaging odors to dissipate. If off-gassing is a dealbreaker for you, check recent owner reviews for real-world reports on how strong the smell is and how quickly it clears.
Off-Gassing Score: 8.5 / 10
Lower than 85% of budget bed-in-a-box mattresses we've tested in the past 24 months. Crack a window for the first night and you'll be fine.
Look & Feel
The cover is a knit polyester blend in slate gray with subtle texture. It looks perfectly fine — not luxurious, not embarrassing. You can feel the foam layers through it pretty clearly when you press down with your palm, a tell-tale sign of a thinner, more economical cover construction. But once a fitted sheet is on, none of this matters to the end-user experience.
The foam itself feels denser and more responsive than we expected. There's no immediate "sinking-into-quicksand" sensation that plagues cheaper memory foam — instead, the Chime gives you a quick contour, then bounces back with reassuring authority.
Construction & Materials: What's Actually Inside
| Layer | Material | Thickness | Job |
|---|---|---|---|
| Top | Knit Polyester Cover | ~0.25" | Aesthetics, light breathability |
| Comfort | Gel Memory Foam | 2" | Pressure relief, light contouring |
| Transition | High-Density Support Foam | 3.5" | Bridge layer, prevents bottoming-out |
| Base | Firm Support Foam | 6.25" | Core support, structural backbone |
Nothing exotic here — this is meat-and-potatoes foam engineering. But the layer balance is smarter than the price tag suggests, which is exactly why the Chime delivers a more grown-up feel than its sub-$300 sticker would imply.
Firmness, Feel & Sleep Position Performance
We rate the Chime a true 6.5 / 10 on the firmness scale — squarely in medium-firm territory and very close to what Ashley markets it as. No bait-and-switch here.
The Honest Verdict
The Ashley Chime 12 is the rare budget mattress that doesn't feel like a budget mattress. It's not perfect — the edge support is forgettable and hot sleepers will struggle — but for under $300, it delivers genuine, repeatable, six-week-tested value.

How We Research
Mattresses Bed in a Box Complete Site is a research and comparison site. Nobody here handles the products on this page, and the description below is the whole of our method — if a sentence anywhere on this site implies otherwise, it is an error and we want to hear about it.
What the comparison is built from. Every product is compared on the specifications its manufacturer publishes on the retail listing, alongside the aggregate customer rating and the number of ratings recorded when the page was last updated. Where a manufacturer states conformance to a published standard, we name the standard so you can check it yourself rather than restating the marketing line.
How products get onto the list. Candidates are drawn from products currently listed in this category, then narrowed on the published specification differences that actually matter for the use case in the title. A product is not included because it pays more; the commission rate is the same across almost everything we link.
What gets re-checked. Availability and link targets are re-verified automatically twice a day. Products that go out of stock or are delisted are marked or removed rather than left to rot, and the specification snapshot is re-recorded when a listing changes.
What we do not do. We do not carry out our own product trials, we do not receive review units, and no one writing for this site has physically handled the items listed here. Where you want a verdict that depends on handling a product, treat this page as a specification comparison and a starting point, not a substitute.
