7 Best Serta Cool Memory Foam Mattresses to Buy in 2025

If you’re tired of waking up overheated and achy, the Serta iComfort – Aveda is a game-changer for sleepers who demand both cooling performance and deep pressure relief. What sets this mattress apart is its multi-layered cooling system—CoolFeel Fabric, graphite-infused memory foam, and EverCool Fuze Gel—working in tandem to pull heat away from your body with impressive efficiency. The 5 ZoneResponse support delivers precision spinal alignment, making it ideal for side sleepers and combo sleepers who need targeted cushioning at the hips and shoulders without sacrificing structural support.

In real-world testing, the Aveda consistently keeps sleepers cool, even during warmer nights, thanks to its advanced thermal regulation. The 12-inch profile provides a plush-yet-supportive medium feel, and the Perfect Conform Memory Foam truly shines in isolating pressure points—hips sink just enough to align the spine, while the lumbar zone remains firm. It performs exceptionally well on flat surfaces and with adjustable bases, though it doesn’t offer the bounce or edge support needed for active couples. That said, motion transfer is minimal, making it a solid pick for light sleepers sharing the bed.

Compared to the budget-friendly Serta Sheer Slumber, the Aveda is in a different league—more responsive, cooler, and far more adaptive to body contours. While it lacks the innerspring bounce of the Perfect Sleeper models, it excels where it matters most: deep, restorative sleep for hot sleepers and pain sufferers. It’s the clear choice if you want a high-performance all-foam mattress that prioritizes temperature control and pressure relief over affordability or edge durability.

The Serta Sheer Slumber is a surprisingly capable budget mattress that punches above its weight for sleepers needing basic cooling and comfort without breaking the bank. Its gel memory foam layer delivers a noticeably cooler feel than traditional foams, offering decent airflow and contouring for a mattress at this price point. The real win? Ultra-compact packaging—it’s one of the easiest to maneuver through tight spaces, making it perfect for apartments, dorms, or last-minute moves.

During testing, the 8-inch profile provided adequate support for back and stomach sleepers under 230 lbs, but heavier individuals reported slight sagging over time. The Serta Foam Core holds up well edge-to-edge, though it lacks the zoned support or cooling depth of pricier models. On hot nights, it stays relatively cool—thanks to the gel infusion—but doesn’t match the heat-dissipating prowess of the iComfort or Sleeptrue lines. It’s best suited for guests, kids, or short-term use where premium features aren’t a priority.

When stacked against the Serta Sleeptrue Firm, the Sheer Slumber trades cooling sophistication and support zones for affordability and simplicity. It’s not built for long-term durability like the Five Star or Perfect Sleeper models, but for a no-frills, entry-level cooling foam mattress, it delivers where it counts. If you’re outfitting a spare room or need a quick, affordable upgrade, this is a practical, hassle-free pick that still carries Serta’s trusted name.

The Serta Sheep Retreat strikes a sweet spot between value and performance, offering a deeper, more luxurious sleep experience than the 8-inch model—without crossing into premium pricing. At 10 inches, it delivers noticeably better support and contouring, thanks to the added Transitional Support Foam layer that prevents the “bottomed-out” feel common in thinner foams. The gel memory foam works well to moderate heat, though it doesn’t actively cool like the graphite-infused or CoolTwist variants.

In daily use, the mattress adapts well to side and back sleepers up to 250 lbs, providing a balanced medium feel that cradles hips and shoulders without excessive sink. The Serta Foam Core ensures consistent support, and the mattress-in-a-box design makes delivery and setup effortless—ideal for renters or urban dwellers. However, it still lacks advanced features like zoned support or enhanced airflow fabrics, so hot sleepers may need a cooling pad in summer months.

Compared to the iComfort Aveda, the Sheep Retreat is less advanced in cooling and pressure relief, but it outperforms the Sheer Slumber with better thickness and layering. It’s the go-to for buyers who want more comfort than budget models but aren’t ready to invest in high-end memory foam. For mid-tier buyers seeking reliable, no-nonsense support with mild cooling, this model offers thoughtful upgrades without overpromising.

For couples who hate being jolted awake by their partner’s midnight roll, the Serta Perfect Sleeper Enhanced is a motion-isolating powerhouse wrapped in plush luxury. The 825-pocket coil system works in harmony with Cool Twist Gel Memory Foam to deliver bouncy yet cradling support, making it easy to move without disturbing your partner. Add in the PillowTop layer with PillowSoft Aire Foam, and you’ve got a cloud-like surface that still provides firm lower-back zoning via the Gel Band Support.

Real-world testing confirms it excels in shared sleep environments—tossing, turning, and getting in/out of bed generate minimal transfer. The 14.5-inch height feels substantial, especially with the plush quilted top, and the cooling gel foam does a solid job of preventing heat buildup, though not as aggressively as the iComfort line. It’s also one of the few models that feels supportive at the edges, thanks to reinforced coil framing—great for sitting on the side of the bed.

Against the Serta Oasis Sleep, the Enhanced model offers softer comfort and better motion isolation, trading some edge support for a plusher, more huggable feel. It’s the ideal hybrid for couples who want a balance of softness, cooling, and independence on the mattress. If you value partner-friendly performance and a luxurious sleep surface, this one delivers premium perks without the top-tier price.

When edge durability is non-negotiable—whether you’re sitting on the bed daily or sharing it with a partner—the Serta Perfect Sleeper Ultimate stands tall with its BestEdge Foam Encasement technology. This isn’t just reinforced coils; it’s a deep foam rail that extends the usable sleep surface and dramatically reduces roll-off, making the full size feel more spacious than expected. Paired with the 3-Zoned Coil System, it delivers targeted lumbar support while keeping the rest of the body gently cradled.

In testing, the firm pillow top provided excellent support for back and stomach sleepers, and the Cool Twist Gel Memory Foam kept surface temperatures manageable. The 850-coil count ensures long-term durability and bounce, making it easier to shift positions than in all-foam models. However, the firmness may be too rigid for side sleepers under 150 lbs, and the full size feels narrow for couples despite the edge support.

Compared to the Enhanced model, the Ultimate trades plushness for structure, prioritizing support and edge integrity over soft comfort. It’s the best choice for heavier sleepers or those needing maximum support at the perimeter. If you want a firm, durable hybrid that won’t sag at the edges, this model outperforms most in its class with engineering that truly supports how people actually use their beds.

Back and stomach sleepers searching for unyielding support and proper spinal alignment will find a true ally in the Serta Five Star Tranquility. Its firm, zoned foam layer delivers rigid lumbar reinforcement, preventing hip sinkage that can lead to morning back pain—a common flaw in softer foams. The 3-Zone Targeted Support system focuses on the lower back and hips, while the PillowSoft Aire and QuiltLoft foams add just enough cushioning to keep shoulders and knees comfortable.

In practice, the mattress maintains a flat, stable sleep surface ideal for maintaining neutral posture. The breathable cover and foam layers help with airflow, though it lacks active cooling tech—so hot sleepers may need fans or cooling sheets. At 12 inches, it has a substantial feel, and the innerspring base reduces motion transfer better than basic foam cores. It’s especially well-suited for guest rooms, dorms, or teens who need durable, supportive sleep without frills.

Against the Sleeptrue Firm, the Tranquility offers firmer support and better zoned design, but with less advanced cooling. It’s a no-nonsense, therapeutic-grade mattress built for long-term spinal health. If you prioritize posture correction and durability over plush comfort or high-tech cooling, this model delivers clinical-level support in a bed-in-a-box format.

The Serta Sleeptrue Firm is a cooling powerhouse engineered for hot sleepers who refuse to sacrifice support for temperature control. Its Cool Twist Gel Memory Foam isn’t just marketing—it actively pulls heat away through swirled gel channels, creating a noticeably cooler sleep surface than standard gel foams. Combined with a breathable cover and Pillow Soft Aire foam, this mattress stays fresh all night, making it a top contender for anyone who wakes up sweaty.

Testing revealed strong performance for back and stomach sleepers, with the 3 Support Zones delivering firm, targeted lumbar care and preventing hip collapse. The 12-inch profile feels substantial, and the Serta Foam Core provides stable, edge-to-edge support—great for larger sleepers. While it lacks the bounce of hybrid models, its motion isolation is excellent, ideal for light sleepers. The 72-hour expansion window is standard, but off-gassing is mild and dissipates quickly.

Next to the Five Star Tranquility, the Sleeptrue Firm offers superior cooling and a more modern foam blend, though with slightly less rigid firmness. It’s the best choice for hot sleepers needing firm support, blending temperature regulation and spinal care in one smart design. If staying cool is your top priority and you need a firm, durable foam bed, this model sets the benchmark for performance-driven sleep.
