Pocket Spring vs. Memory Foam: Which Mattress Sleeps Cooler?
If you're a hot sleeper — or you live in Los Angeles, where nights don't always cool off the way you'd like — mattress temperature is a real consideration. The wrong mattress can turn a warm night into a genuinely miserable one.
So let's answer the question directly: pocket spring mattresses generally sleep cooler than traditional memory foam. But the full answer is more nuanced, and there are excellent cooling options on both sides. Here's everything you need to know.
02The Short Answer
Pocket spring mattresses have open space between coils that allows air to circulate freely. Memory foam is a dense material that traps heat by design — your body warmth is what activates its contouring properties.
That said, the mattress industry has largely addressed memory foam's heat problem. Gel-infused foam, open-cell foam, copper infusions, and phase-change covers have all reduced heat retention significantly in higher-quality models. A cheap pocket spring will often sleep hotter than a well-engineered gel memory foam.
03How Each Mattress Type Handles Heat
Pocket Spring Mattresses
Each coil in a pocket spring mattress is individually wrapped in fabric and operates independently. The gaps between these coils allow air to move through the mattress as you breathe and shift during sleep. Heat dissipates passively.
Additional benefits of pocket spring construction:
- Targeted, responsive support — coils react to individual body zones
- Excellent durability (coils don't compress permanently like foam)
- Natural airflow without requiring added cooling technology
Memory Foam Mattresses
Memory foam (viscoelastic foam) was originally developed for aircraft cushioning. It contours to your body using your body heat — which is also why it retains that heat rather than releasing it.
Traditional memory foam's heat retention is a real limitation. Modern solutions include:
- Gel-infused foam: Gel beads or swirls draw heat away from the body
- Open-cell foam: A restructured foam matrix that allows more airflow
- Copper or graphite infusions: Conductive materials that transfer heat away
- Phase-change covers: Fabric technology that absorbs excess heat at the surface
These innovations don't make memory foam as breathable as coil-based mattresses, but they close the gap significantly.
04Cooling Performance Comparison
| Feature | Pocket Spring | Memory Foam (Standard) | Memory Foam (Gel/Cooling) |
|---|---|---|---|
| Airflow | Excellent | Low | Low to Moderate |
| Heat Retention | Low | High | Moderate |
| Breathability | High | Low | Moderate |
| Motion Isolation | Moderate | Excellent | Excellent |
| Pressure Relief | Moderate | Excellent | Excellent |
| Best for Hot Sleepers? | Yes | No | Depends on quality |
05The Hybrid Middle Ground
Hybrid mattresses combine pocketed coils for airflow and structural support with foam comfort layers for pressure relief and motion isolation. For most hot sleepers who also want contouring and motion isolation, a well-built hybrid is the best of both worlds.
What to look for in a cooling hybrid:
- Pocketed coil base (not Bonnell or offset coils)
- Gel-infused or open-cell foam comfort layers
- Breathable or phase-change cover fabric
- Minimal thick foam transition layers that can trap heat
06Other Factors That Affect Sleep Temperature
The mattress is one piece of the puzzle. These other variables have a real impact:
- Bed base: A slatted bed frame allows airflow beneath the mattress. A solid platform or box spring blocks it. If you're sleeping hot on a coil mattress, check what it's sitting on.
- Mattress cover: Bamboo, Tencel, and organic cotton covers breathe better than polyester. Some mattresses come with phase-change covers that actively manage surface temperature.
- Bedding: Your sheets and comforter have more direct impact on your skin temperature than almost anything else. Switching to percale cotton or linen can help as much as changing your mattress.
- Body weight: Heavier sleepers sink deeper into foam, increasing surface contact and heat buildup. A firmer or more supportive mattress can help by limiting how much you sink.
- Room temperature: A room above 70°F will make even the best cooling mattress struggle. Aim for 65–68°F if possible.
07Top Cooling Mattresses at LA Mattress Store
Englander Supreme Allendale Royal Firm Euro Top 16"
This mattress is built for hot sleepers who don't want to sacrifice support. The zoned pocket coil system creates excellent airflow while targeting lumbar support, and the gel-infused Visco memory foam comfort layers cool the surface. At 16 inches, it has a commanding presence — and the Euro Top finish adds comfort without the heat-trapping common in thick pillow tops.
It pairs particularly well with an adjustable base, which elevates the mattress and further improves airflow underneath.
| Pros | Cons |
|---|---|
| Excellent airflow from zoned pocket coil base | May feel too firm for side sleepers |
| Gel-infused foam manages surface heat | Premium price point |
| Strong edge support across full width | Heavy — plan for white glove delivery |
| Adjustable base compatible | Firm feel isn't suited for everyone |

Diamond Glory Plush Gel Swirl Memory Foam
For people who want the contouring comfort of memory foam but struggle with heat, the Glory addresses memory foam's main weakness with gel swirl-infused layers that distribute and dissipate heat as you sleep. CertiPUR-US certified materials mean no off-gassing surprises.
This is a plush mattress — it's designed to wrap around you. If you're a side sleeper who runs warm, this is a strong choice.
| Pros | Cons |
|---|---|
| Gel swirl foam sleeps cooler than standard memory foam | Minimal bounce — not easy to change positions |
| Excellent body contouring and pressure relief | Can feel too soft for back or stomach sleepers |
| CertiPUR-US certified | Less edge support than hybrid designs |
Eclipse Peacefulness Hybrid 12" Plush
A thoughtfully balanced hybrid: pocketed coils for airflow and support, plush foam layers for pressure relief, and a cooling knit cover at the surface. It works for back, side, and combination sleepers — which makes it a good choice for couples with different sleeping styles who both run warm.
| Pros | Cons |
|---|---|
| Airflow from coil base + cooling cover at surface | Not firm enough for those needing orthopedic support |
| Balanced feel suits most sleep positions | Edge support could be stronger |
| Good motion isolation for couples | Some motion transfer compared to all-foam designs |

09Frequently Asked Questions
Do pocket spring mattresses always sleep cooler than memory foam?
Generally yes, because their open coil structure allows passive airflow. But a cheap pocket spring mattress with thick foam comfort layers can sleep hotter than a high-quality gel memory foam. Construction and materials matter more than category alone.
Is gel memory foam actually cooler?
Meaningfully cooler than standard memory foam, yes. Whether it's cool enough for a hot sleeper depends on the quality and quantity of gel infusion. Surface-layer gel tends to help most at the point of initial contact; it doesn't eliminate heat retention in denser lower layers.
Do hybrid mattresses sleep cool?
Yes, especially hybrids with a full pocketed coil base. The coils provide consistent airflow throughout the night. Paired with gel foam comfort layers and a breathable cover, hybrids are often the best cooling option for people who also need pressure relief.
What mattress type is best for motion isolation?
Memory foam, particularly traditional or gel-infused types. Pocket spring mattresses have improved significantly in motion isolation, but all-foam designs still absorb movement more completely.
Does my bed base affect how hot I sleep?
Yes, significantly. A slatted frame improves airflow beneath the mattress. A solid platform or box spring blocks airflow and can make any mattress sleep warmer. If you're on a platform bed and sleeping hot, a slatted insert can help.
Should side sleepers choose pocket spring or memory foam?
Side sleepers benefit from the pressure relief that memory foam or plush hybrid tops provide at the hips and shoulders. A plush hybrid — pocketed coils with a soft foam layer — gives side sleepers the best combination of cooling and pressure relief.
Are cooling mattress covers worth it?
Yes. Phase-change covers and Tencel/bamboo fabrics make a noticeable difference at the surface — which is where your skin actually contacts the mattress. It's often the most cost-effective cooling upgrade you can make.
