Mattress Miles carries a mix of bed-in-a-box foam and coil builds, so we focused on four Sierra Sleep by Ashley models that span the most common “feel” buckets: ultra plush, medium hybrid, firm hybrid, and plush Euro top. We evaluated support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability. The lineup is strongest for shoppers who want clear firmness choices, and least suited for anyone chasing a single “one-feel-fits-all” mattress.

How We Tested It
We rotated each mattress through the same bedroom setup and used the same pillows and bedding to keep the feel comparisons clean. I tracked overnight alignment and morning stiffness, Marcus focused on heat buildup and hip support, and Jenna and Ethan ran repeatable partner-movement and edge-use checks. We scored each mattress on Support, Cooling, Pressure Relief, Motion Isolation, Responsiveness, Edge Support, and Durability. Those metrics are the full basis for the scoring tables that follow.
Mattress Miles: Our Testing Experience
Chime 12 Inch Memory Foam
Our Testing Experience
Unboxing was the classic “cut the plastic and watch it rise” routine, and the surface immediately read as soft and forgiving. I noticed the best moments when I stayed on my side for long stretches—my shoulder settled in without that sharp pressure build. When I rolled onto my back, the foam cradled me, but I had to pay attention to keeping my hips from sinking too far. Jenna and Ethan both liked how calm the surface stayed when one of them shifted position at 2 a.m., but Marcus felt the top warmed up faster than he prefers.
- What we liked
- Very low motion transfer for shared sleep
- Plush surface that eases shoulder/hip pressure
- Comfortable “reading in bed” sink without harsh pushback
- Who it is best for
- Lighter-to-average side sleepers
- Couples who wake easily from movement
- Guest rooms where “soft comfort” is the goal
- Where it falls short
- Hot sleepers who notice heat buildup quickly
- Stomach sleeping (too much sink at the hips)
- People who sit on the edge often
Pros & Cons
| Pros | Cons |
|---|---|
| Excellent motion isolation | Softer edge support |
| Strong pressure relief | Foam can feel warmer |
| Easy, forgiving surface | Slower repositioning |
Details
- Comfort level: ultra plush
- Construction: thick memory foam layer over firm support foam
- Cover: stretch knit cover
- Hypoallergenic materials called out
- Setup: ships in a box; easy unroll setup
- Verified size options shown: Twin, Full, Queen, King, California King
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 3.8 | Supportive enough on back, but hips can sink for some bodies |
| Cooling | 3.4 | Foam feel trends warmer in longer sessions |
| Pressure Relief | 4.5 | Best-in-set for joint comfort on the side |
| Motion Isolation | 4.6 | Partner movement stays localized |
| Responsiveness | 3.2 | Slow rebound makes quick turns less effortless |
| Edge Support | 3.1 | Fine for sleeping near edge, less confident for sitting |
| Durability | 3.6 | Softer foams tend to show feel changes sooner over time |
| Overall | 3.9 | A comfort-first foam option with trade-offs in heat and edges |
Chime 10 Inch Hybrid
Our Testing Experience
This one felt immediately more “structured” under me than the all-foam Chime. When I slid from side to back, I didn’t have that slow, sticky resistance; the surface gave a quicker, more elastic return. Marcus liked the added support at the hips and lower back and said it stayed more temperature-neutral through the night. The couple test was more mixed: Jenna and Ethan felt more movement than on the 12-inch foam model, but it still avoided the trampoline effect. Edge-wise, both of them noticed they could use the outer third of the bed without that “rolling off” sensation.
- What we liked
- More balanced support for mixed positions
- Easier turning and repositioning
- More stable edge feel for sitting and getting up
- Who it is best for
- Combo sleepers who change positions
- People who dislike slow-sinking foam
- Couples who want a middle-ground feel
- Where it falls short
- Those who want an ultra-plush top
- Shoppers chasing maximum motion dampening
- Anyone who prefers a deep, slow “hug”
Pros & Cons
| Pros | Cons |
|---|---|
| Solid all-position support | More motion than all-foam |
| Easier movement | Not a plush “sink-in” feel |
| Better edge use | Some coil bounce sensation |
Details
- Comfort level: medium
- Comfort layers: gel memory foam lumbar support + quilt foam
- Support core: wrapped coils; perimeter coil rows called out for edge-to-edge support
- Hypoallergenic materials called out
- Warranty: 10-year non-prorated
- Verified dimensions include 10-inch height across common sizes
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.2 | Better hip hold and lumbar steadiness than foam-only |
| Cooling | 3.9 | Coil core helps; stayed more neutral for Marcus |
| Pressure Relief | 4.0 | Comfortable, but less “pillowy” than the ultra-plush foam |
| Motion Isolation | 3.8 | Noticeable movement, but not disruptive for most couples |
| Responsiveness | 4.1 | Turns feel smoother and faster |
| Edge Support | 4.1 | More confident sitting/edge sleeping than all-foam |
| Durability | 4.0 | Coil support core and firmer build should hold shape well |
| Overall | 4.0 | The “default choice” if you want balance without extremes |
Hybrid 1300
Our Testing Experience
The Hybrid 1300 read firm the moment I lay down: less initial sink, more straight-line support. On my back, it kept my lower back from dipping, which mattered on mornings when my desk-work stiffness was noticeable. When I stayed on my side, I felt more pressure at the shoulder than on the plusher models, so I had to be deliberate about pillow height and arm position. Marcus liked this one most for support—no hammock sensation at the hips—and he called out the edge as the most stable of the group. Jenna and Ethan agreed the perimeter felt secure when they both drifted outward.
- What we liked
- Strong spinal alignment feel on back sleeping
- Most stable edges for sitting and sleeping near the perimeter
- Consistent, supportive surface night to night
- Who it is best for
- Back sleepers who want a firmer hold
- Heavier bodies needing stronger hip support
- People who value edge stability
- Where it falls short
- Shoulder-sensitive side sleepers
- Plush-top fans
- Anyone wanting a “deep cushion” first impression
Pros & Cons
| Pros | Cons |
|---|---|
| Excellent support and stability | Firm feel can be less forgiving |
| Best edge support in the set | Less pressure relief for shoulders |
| Good long-term structure | Not the softest comfort layers |
Details
- Comfort level: firm
- Foam layers: response memory foam + whisper foam
- Coil system: 720 wrapped coils; steel-encased edge and perimeter coil rows noted
- Cover: 4-way stretch cover
- Setup: ships in a box; expansion time guidance provided
- Warranty: 10-year non-prorated
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.6 | Firm, steady support that resists hip sink |
| Cooling | 3.7 | Coil airflow helps, but firmness makes you sleep “on top” more than “in” |
| Pressure Relief | 3.7 | Fine for back, less forgiving for shoulders on the side |
| Motion Isolation | 4.0 | Controlled for a firmer hybrid |
| Responsiveness | 4.0 | Easy to move without feeling springy |
| Edge Support | 4.5 | Most confident edge performance of the four |
| Durability | 4.3 | Robust coil/edge build suggests strong shape retention |
| Overall | 4.2 | A support-forward hybrid with the expected firmness trade-offs |
Plush Luxe 2.0
Our Testing Experience
The first thing I noticed was the Euro-top “pillow” feel—more cushion than the Hybrid 1300, but without the slow, stuck-in-foam sensation. On my side, it gave me the most consistently comfortable shoulder and hip pressure relief across multiple nights, and when I rolled to my back, the support stayed present instead of collapsing. Jenna and Ethan said it hit the best couple compromise: quieter than the hybrids that feel bouncier, but easier to move on than the all-foam Chime. Marcus liked the surface comfort but said he’d be cautious if someone spends a lot of time stomach sleeping; the plushness can encourage a slight hip dip.
- What we liked
- Best blend of plush comfort and support
- Easy movement for a pillow-top feel
- Strong “shared bed” performance without feeling dead
- Who it is best for
- Side sleepers who still want support
- Couples seeking balanced feel
- People who want plush without extreme sink
- Where it falls short
- Firm-only sleepers
- Heavier stomach sleepers
- Anyone who dislikes taller profiles
Pros & Cons
| Pros | Cons |
|---|---|
| Excellent pressure relief | Plush feel isn’t for everyone |
| Balanced motion + mobility | Taller profile can feel bulky |
| Strong edge and overall stability | Can allow some hip sink for stomach sleepers |
Details
- Comfort level: plush
- Comfort materials called out: memory foam, quilt foam, cooling gel latex, Laytech foam
- Support: wrapped coil unit with Ashley Edge noted
- Cover: Hyper Cool luxury 4-way stretch knit cover
- Profile height: 15 inches
- Warranty: 10-year non-prorated
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.1 | Supportive under back, but plush top can soften the feel |
| Cooling | 4.1 | Cooling cover + gel latex called out; stayed comfortable overnight |
| Pressure Relief | 4.6 | Most consistently comfortable for side sleeping |
| Motion Isolation | 4.2 | Controlled movement without a “dead” surface |
| Responsiveness | 4.2 | Easier to reposition than typical plush foam builds |
| Edge Support | 4.2 | Stable perimeter for couples using the outer third |
| Durability | 4.1 | Strong overall build; plush top is the main long-term watch item |
| Overall | 4.3 | The best all-around pick if you want plush comfort without losing support |

The most “even” performers are Plush Luxe 2.0 and Chime 10 Inch Hybrid—they avoid major weak spots while still having a clear personality. Hybrid 1300 is the specialist: standout support and edge stability, with a clear trade-off in side-sleeper pressure relief. Chime 12 Inch Memory Foam is the comfort-and-quiet pick, but it’s the least strong on cooling and edge use.
How to Choose a Mattress Miles Mattress
Start with sleep position and body weight: side sleepers usually need more pressure relief, while back and stomach sleepers need stronger hip support. If you sleep hot, prioritize a coil-based core. If you share a bed, decide whether you want maximum motion isolation (foam) or easier movement (hybrid/coil). For lightweight side sleepers or guest rooms, choose Chime 12 Inch Memory Foam. For combo sleepers who want a true middle feel, pick Chime 10 Inch Hybrid. For back sleepers or heavier bodies needing firm stability, go Hybrid 1300. For couples and side sleepers who want plush comfort without giving up structure, Plush Luxe 2.0 is the strongest fit.

Pro Tips for Mattress Miles
- If you’re a side sleeper, spend at least 15 minutes on your side in-store and check for shoulder numbness.
- For back sleeping, watch for a “gap” under the lower back or an over-arched feeling—both are red flags.
- In couple testing, have one person get in/out of bed and do three deliberate turns to gauge motion.
- Sit on the edge like you’re tying shoes; if you feel sliding, edge support may bother you long-term.
- If you run hot, favor coil-based builds and breathable bedding; foam comfort can trap warmth.
- Give new mattresses time to settle; initial feel can change as layers relax.
- If you switch positions often, prioritize responsiveness over maximum sink.
- Match pillow loft to mattress firmness: firmer beds often need a slightly taller pillow for side sleeping.
- Use a consistent, supportive foundation to avoid adding wobble or changing the feel.
