Winterport Mattress

This lineup runs from a traditional, flippable coil build to a modern, zoned memory-foam bed. Agren is the firm durability pick; SleepTrue is the softest for pressure relief; Sealy’s hybrid and Serta’s iComfort sit in the middle with stronger posture control and better temperature management; and Sealy’s Response Performance is the value innerspring.

Our heavier testers (Marcus and Jamal) preferred beds that kept hips from dipping: Agren and the Sealy hybrid were steadiest, while SleepTrue felt softer and less stable on stomach. iComfort held alignment well for an all-foam bed.

Mia favored SleepTrue for shoulder comfort. For couples, motion transfer was highest on the bouncier innersprings and lowest on the hybrid and iComfort. Start with sleep position and body weight, then use temperature and partner movement as tie-breakers.

We used the same repeatable framework we rely on for multi-brand mattress comparisons. Every bed ran through the same hands-on checks, and we scored it across support, pressure relief, cooling, motion isolation, responsiveness, edge support, and durability outlook.

Testing included back, side, and stomach positions across different body types, then we compared notes and scored each category.

• Support: Spinal alignment and hip/shoulder balance.
• Pressure relief: Shoulder/hip/knee pressure in side sleeping.
• Cooling: Material checks plus heat build-up in longer sessions.
• Motion isolation: Partner movement transfer across the surface.
• Responsiveness: Ease of rolling and changing positions.
• Edge support: Sitting and lying near the perimeter.
• Durability outlook: Construction review (coils, foams, flippable design).

Those results roll up into the tables and final scores below.

Our Testing Experience

The Agren Winterport is the most traditional-feeling bed in this lineup—in a good way. It’s a two-sided innerspring with a deep quilt, a buoyant surface, and a firm baseline that you notice right away.

On my back, it kept my hips level and my lower back supported without feeling like I was balancing on the springs. Side sleeping was more of a “supported” feel than a deep cradle. Mia liked the stability but said she’d want a topper if she were using it as a nightly side-sleeper bed.

Marcus (our heavier tester) was the most impressed. His hips stayed lifted when he rolled to stomach, and sitting on the edge barely compressed the perimeter. In his words: firm, but not punishing.

The big advantage is durability. A flippable design gives you two usable comfort surfaces, and this one already feels built to rotate and wear evenly over time.

Our Testing Experience

This Sealy Response Performance cushion-firm is the “classic innerspring” option in the set. The feel sits in the medium-firm range with a thin cushion on top, so it reads supportive first and comfortable second.

On my back, it stayed level through the hips and lower back, and changing positions took almost no effort. Carlos tends to notice mid-back fatigue quickly, and he rated this one steady during longer stillness without feeling harsh.

Side sleeping was the limiter. Mia felt more shoulder and hip pressure here than on the Sealy hybrid or the softer SleepTrue Euro top. It can work for side sleepers who prefer a firmer surface, but it’s not the best choice if you need a deep pressure-relief cradle.

Motion and edge performance landed in the middle: less “trampoline” than older innersprings, but a partner’s movement is still more noticeable than on the hybrid or iComfort. Cooling was solid for a coil mattress, mostly thanks to airflow through the spring unit.

Pros & Cons

Details

• Type: Traditional innerspring.
• Firmness: About 6.5–7/10 (medium-firm).
• Height: 12.5 inches.
• Materials: Encased coils with gel foams and a reinforced edge system.
• Best for: Back sleepers and combo sleepers who like a classic feel.
• Price (queen, approx.): $800–$1,100 depending on retailer.
• Trial/warranty: Sealy direct commonly lists a 90-night trial and 10-year warranty; retailer rules can differ.
• Why it stands out: A familiar, supportive feel without stepping into premium pricing.

Our Testing Experience

The Sealy Posturepedic Hybrid (medium feel, 12" profile) was the most “balanced” option we tested. It has coil lift underneath with enough foam up top to smooth out sharper pressure points.

On my back, I felt a light cradle at the shoulders while my midsection stayed supported and level. Carlos described it as steady in the right places—more like the bed is guiding posture than letting you sink.

In couple testing, it separated movement better than the traditional innerspring. Jenna could tell when Ethan turned, but it didn’t ripple across the surface the same way the bouncier beds did. Mia found it comfortable on her side, though she still preferred the SleepTrue if softness is the main goal.

Cooling was a strength. The coil core adds airflow, and the cooling cover/gel foams kept it closer to neutral than the plush Euro top. If you want one mattress that covers the most sleep styles without feeling extreme, this is the safest middle ground.

Pros & Cons

Details

• Type: Hybrid (foam over coils).
• Firmness: About 6/10 (true medium).
• Height: 12 inches.
• Materials: PrecisionFit-style coils with gel memory foam and a cooling cover.
• Best for: Back/combination sleepers; hot sleepers; couples who want lower motion than a basic spring bed.
• Price (queen, approx.): $1,300–$1,600 depending on retailer.
• Trial/warranty: Sealy direct commonly lists a 90-night trial and 10-year warranty; retailer rules can differ.
• Why it stands out: Strong balance of support, pressure relief, and temperature control.

Review Score

Our Testing Experience

The SleepTrue Plush Euro Top is the softest surface in this group. It has that smooth, cushy Euro-top feel with a supportive innerspring core underneath.

Mia called it the easiest on her shoulders. On her side, the comfort layers let her shoulder sink without a sharp pushback, which is exactly what lighter side sleepers tend to chase.

As a combo sleeper, I felt comfortable on my back right away, but the plush top lets you settle in more than on the Sealy models. Marcus made the main limitation clear: once he rolled to stomach, his hips started to drift, so heavier stomach sleepers should be cautious.

Edge support was the weak spot. Sitting and lounging near the perimeter felt less secure than on the firmer beds, and the surface compresses more when two people crowd one side.

Cooling was decent but not the best in the set. The coil core helps, but a thicker plush top can hold more warmth than a hybrid with a thinner comfort stack.

Pros & Cons

Details

• Type: Plush Euro-top innerspring.
• Firmness: About 5–5.5/10 (plush).
• Height: Roughly 11.5–12.5 inches depending on version.
• Materials: PillowSoft Aire-style cushioning with gel memory foam over coils.
• Best for: Petite/average side sleepers; guest rooms; anyone who wants a softer top feel.
• Price (queen, approx.): $700–$1,000 depending on retailer.
• Trial/warranty: Often retailer-dependent; some listings include a 100-night trial and 10-year warranty.
• Why it stands out: The clearest shoulder-relief option in the Winterport set.

Our Testing Experience

The iComfort 11.5" firm foam is the most modern-feeling bed in this lineup. It’s an all-foam build with firmer, zoned support, so the surface feels controlled and consistent rather than plush.

On my back, the contour felt precise—enough give to take pressure off, but not enough sink to pull my hips down. Mia was also surprised that, despite the firm label, her shoulder could dip without hitting a hard stop.

For Marcus, heat and alignment told the story. He stayed more level than on the plush Euro top, and he reported less heat build-up than he typically expects from memory foam.

Couples testing is where it separated itself. Motion transfer was the lowest of the five, which is ideal if one person tosses and the other wakes easily. The tradeoff is less bounce and a slower feel than the coil-based options.

Pros & Cons

Details

• Type: All-foam memory foam.
• Firmness: About 7/10 (firm).
• Height: 11.5 inches.
• Materials: Cooling cover, graphite-infused memory foam, and a 5-zone support core.
• Best for: Back/stomach sleepers, hot sleepers, and motion-sensitive couples.
• Price (queen, approx.): $1,100–$1,600 depending on version and promotions.
• Trial/warranty: iComfort direct often includes a 100-night trial and 10-year limited warranty.
• Why it stands out: Strong motion isolation with better cooling than many foam beds.

Review Score

Start with body weight and sleep position. The same “medium” or “firm” label can feel completely different depending on how much you sink in, so pick for alignment first and then refine for cooling and partner disturbance.

If you’re a light-to-average side sleeper who wakes up with shoulder or hip pressure, the SleepTrue Plush Euro Top is the easiest on joints in this group. If you want a more balanced feel without giving up too much contour, the Sealy Posturepedic Hybrid is the next step up.

For back sleepers, the Sealy Response Performance is the straightforward medium-firm option, while the Sealy hybrid adds more contour and better motion control. Heavier bodies and stomach sleepers generally did best on the Agren’s firm, flippable build or the iComfort’s firm, zoned foam feel.

If you run hot, prioritize airflow and temperature-management materials—the hybrid and iComfort stayed closest to neutral in our sessions. For couples, iComfort is the quietest surface for partner movement, with the hybrid close behind.

Winterport is a retailer, not a mattress brand. It carries multiple brands and collections, so ask for the exact model name and build before you compare.

Prioritize alignment. In this set, the Sealy hybrid and Serta iComfort kept hips steadier while still cushioning; if you want the firmest lift, Agren is the most support-forward.

The Sealy hybrid and iComfort stayed closest to neutral in longer sessions. Response Performance ventilates well, while the plush SleepTrue top can hold a bit more warmth.

For very petite side sleepers, it can feel too firm at the shoulder. If you want more contour, start with the Sealy hybrid; if you want the softest pressure relief, SleepTrue is the plush pick.

SleepTrue is softer with deeper shoulder/hip relief. The Sealy hybrid is more balanced and holds posture better through the midsection—choose based on whether pressure relief or alignment is your bigger issue.

iComfort has the lowest motion transfer, with the Sealy hybrid close behind. Agren has strong edges but more bounce; SleepTrue is comfortable but the edges compress more.

Heavier sleepers did best on Agren and the Sealy hybrid because both stayed steadier through the hips. iComfort can work if you want foam and low motion; SleepTrue is usually too soft for heavier stomach sleepers.

SleepTrue is a crowd-pleasing soft feel for occasional use. If you want a more neutral, supportive feel for a wider range of guests, the Sealy Response Performance is the safer default.

Some versions sold online can arrive compressed, but in-store delivery is often full-size. Packaging depends on the exact model and seller, so confirm before checkout.

Hybrid is bouncier and more responsive; iComfort is quieter for motion with a firmer foam contour. Choose based on whether you prefer springy lift or low-motion foam.
