Eclipse Mattress Reviews (2026)

Across these four models, the Curve Hybrid felt the most tuned for adjustable bases and quick movement, while the Ice I-Class delivered the most classic cooling-plus-memory-foam pressure relief. The Ice E-Class was bouncier and more elastic, and the YourCOMFORT Chill made it easiest to dial in firmness without giving up edge stability. For hot sleepers, the Ice line stayed the most consistently comfortable over long nights.

We tested each mattress on the same foundation using our how we test mattresses checklist, rotating placement and logging nightly notes. We used one checklist for support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability. Jenna and Ethan repeated partner-movement drills, while Marcus ran heat and edge stress tests (sitting, tying shoes, and “half-on/half-off” lounging). I tracked alignment and lower-back feel after long desk days, then rechecked the same positions after a short break-in period.

Our Testing Experience

The response was immediate. Rolling from my back to my side felt quick and controlled—there wasn’t that “sink, then climb out” moment you get with slower foams.

On an adjustable base, the bend stayed smooth and supportive, and the center third held up when I sat to put on socks. Marcus pushed it with warm-room testing and heavier bedding, and it still ran cooler than most hybrids we’ve had in rotation. During partner-movement drills, Jenna and Ethan found it more composed than they expected for a springier build, especially in a medium-firm setting.

What we liked

• Fast, effortless turning with a supported, buoyant feel

• A cooler-to-the-touch top that held up over long nights

• Strong edges for sitting and minimal edge drift

Who it is best for

• Combination sleepers who change positions often

• Couples who want stability without a dead surface

• Adjustable-base users who want a mattress that follows the frame

Where it falls short

• Premium pricing can be hard to justify for budget shoppers

• Not the best match if you want a deep, slow memory-foam hug

• Softer settings can feel too plush for strict stomach sleepers

Our Testing Experience

It felt cool as soon as I lay down—more like a cool sheet than a fleeting “cold spot.” I appreciated it most on nights when my lower back felt tight: the midsection stayed steady, while the top gave my shoulders more pressure relief when I started on my side.

Marcus, who tends to overheat quickly, said the surface stayed comfortable longer than he expected. In partner-movement drills, Jenna and Ethan also noted less bounce during entry and exit than you get on latex-forward mattresses.

What we liked

• Cool-to-touch surface feel that stayed noticeable overnight

• Cushioned pressure relief without losing midline support

• Lower motion disturbance during partner movement drills

Who it is best for

• Hot sleepers who still want a more traditional, cushioned top

• Back sleepers needing stable midsection support

• Couples who prioritize quieter movement

Where it falls short

• Turning has more “memory foam drag” than latex or springy hybrids

• Plush feel can feel too yielding for strict stomach sleepers

Our Testing Experience

This was the quickest “snap back” option in the lineup. I could stretch, roll, and settle without feeling pinned, and it stayed cooler even when I used a thicker comforter.

The latex-and-micro-coil build has more spring. Jenna and Ethan felt more movement than on the I-Class, but it never turned chaotic. Where it really shined was how quickly it reset—after I got up for water, the surface felt even again almost immediately.

What we liked

• Very quick response with less of a “stuck” sensation

• Strong cooling performance in warm conditions

• Stable edge with a lively, supported top

Who it is best for

• Hot sleepers who also want bounce and fast recovery

• Combination sleepers who hate slow foam

• People who prefer a more elastic, lifted feel

Where it falls short

• More bounce than the I-Class for light sleepers sharing a bed

• Less “deep hug” than memory-foam-forward builds

Pros & Cons

Our Testing Experience

This was the most “pick your feel” option. I started with a medium setting, then spent a week on a softer feel to see how much the pressure relief changed.

The surface stayed cool and dry-feeling, and the lumbar-zone support was most noticeable when I was flat on my back reading. Marcus preferred firmer for hip support, while Jenna and Ethan liked that the edge stayed dependable even when they drifted outward. It doesn’t have the same springy pop as the E-Class, but it felt balanced once the firmness matched the sleeper.

What we liked

• Five firmness choices make it easier to match your sleep style

• Noticeable lumbar-zone stability for back sleeping

• Stable edge support across different feels

Who it is best for

• Mixed-position sleepers and households split on firmness

• People who want cooling without an overly bouncy surface

• Couples who need predictable edge use

Where it falls short

• Less lively than the latex-forward E-Class

• Comfort varies a lot by firmness, so the “right pick” matters

The Curve Hybrid is the most even “do-everything” option, with top-tier support and easy movement. The Ice E-Class has the clearest advantage in cooling plus responsiveness, while the Ice I-Class is the best fit if you want cooling with a more cushioned, pressure-relieving top. The YourCOMFORT Chill is the most adaptable—its ceiling depends on picking the right firmness.

Start with the basics of how to choose a mattress—your preferred feel and how fast you like to move on the surface. If you change positions often, the Curve Hybrid and Ice E-Class are the easiest to roll and reset. If you prefer a calmer, more cushioned top, the Ice I-Class is the safer starting point.

For hot sleepers, the Ice models were the most consistently comfortable in our rotation, with E-Class feeling the most airflow-like. If you and your partner can’t agree on firmness, the YourCOMFORT Chill makes it easiest to dial in a feel without switching models. Lighter side sleepers usually do better in the softer Chill settings or an I-Class plush, while heavier back and stomach sleepers generally need firmer options to keep hips from sinking.

• Pick firmness based on your dominant position, not your “aspirational” one.

• Give each model a real break-in window, and use the mattress trial period before judging pressure relief.

• If you sleep hot, use breathable sheets so the cooling cover can do its job.

• For couples, prioritize edge support if either of you drifts outward at night.

• If you use an adjustable base, start with a gentle incline and adjust over a week.

• Rotate on a consistent schedule so the feel stays even across the surface.

• For low-back tightness, test alignment on your back for 10 minutes before committing.

• If you like bounce, favor E-Class; if you want calm, favor I-Class.

• Use a pillow height that matches how much your shoulder sinks when you’re on your side.

The Ice E-Class, thanks to its faster, springier response.

The Ice models overall. In our rotation, E-Class ran coolest, while I-Class added more cushioned pressure relief.

YourCOMFORT Chill, since the five firmness options make it easier to match preferences without switching models.
