01Best Mattresses for Summer: How to Sleep Cool When Temperatures Rise

Los Angeles summers are no joke. When nighttime temps stay in the high 70s and your bedroom holds heat from the day, the wrong mattress makes it dramatically worse. The right one barely registers the heat — you just sleep.

This guide covers exactly what makes a mattress sleep cool, the best summer mattress options available at LA Mattress Store, and how to match one to your sleep style.

03What Actually Makes a Mattress Sleep Cool

Not all "cooling" mattresses are equal. There are four real mechanisms that reduce heat retention:

  • Airflow through the support layer: Innerspring and hybrid mattresses have coil systems that allow air to circulate freely. All-foam mattresses block airflow at the base — the single biggest factor in heat retention.
  • Open-cell or gel-infused foam: Traditional memory foam is dense and traps heat. Open-cell foam and gel-infused foam dissipate heat more effectively. This helps — but less dramatically than coil-based airflow.
  • Phase-change materials (PCM): Advanced covers and comfort layers use PCM to absorb excess body heat and release it away from the sleep surface. Found in premium cooling mattresses like the TEMPUR-ProBreeze line.
  • Breathable cover fabrics: Moisture-wicking covers (Tencel, cotton, bamboo-derived) help manage sweat and surface temperature. A good cover won't make a hot mattress cool, but it supports the overall system.

Bottom line: if you sleep hot, a hybrid or innerspring mattress will outperform any all-foam mattress regardless of what the foam marketing says.

04Best Mattress Types for Hot Sleepers

Mattress Type Cooling Performance Best For Watch Out For
Hybrid Very Good Most sleepers; couples Higher price than basic foam
Innerspring Excellent Hot sleepers; traditional feel Less contouring for side sleepers
Natural Latex Very Good Eco-conscious; durable Premium price; heavy
Gel Memory Foam Moderate Pressure relief priority Still retains some heat
Standard Memory Foam Poor Motion isolation; budget Hot sleepers will struggle

06How to Choose the Right Summer Mattress

Use this framework to narrow it down:

  1. Hot sleeper severity: Mildly warm → gel foam hybrid works fine. Very hot → go for phase-change materials (TEMPUR-ProBreeze) or natural latex.
  2. Sleep position: Side sleeper → plush hybrid or gel pillow top. Back/stomach sleeper → firmer hybrid or latex. Combination → medium hybrid.
  3. Budget: Under $800 → Diamond Envoy or Englander Grenadier. Mid-range → Sealy Copper II or Diamond Technogel. Premium → TEMPUR-ProBreeze or Harvest Green Latex.
  4. Partner considerations: If you share the bed, hybrid mattresses offer the best balance of motion isolation, edge support, and cooling for two people.

07Extra Tips to Sleep Cooler This Summer

Even with a great mattress, a few other factors matter in LA summers:

  • Use a breathable mattress protector (Tencel or cotton, not plastic-backed) — a cheap plastic protector traps heat regardless of your mattress
  • Switch to moisture-wicking sheets (percale cotton, bamboo-derived, or linen) — avoid polyester blends in summer
  • Keep a fan circulating air across the bed, not just cooling the room
  • Cool your bedroom for 30–60 minutes before sleep — mattresses take time to equalize to room temperature

08Frequently Asked Questions

What mattress type sleeps coolest?

Innerspring and hybrid mattresses sleep the coolest overall due to airflow through the coil system. Natural latex is close behind. Gel memory foam is better than standard foam but still trails coil-based options significantly.

Do gel-infused foam mattresses actually stay cool?

They're better than standard memory foam, but the improvement has limits. Gel foam dissipates heat at the surface but doesn't have the through-mattress airflow of a hybrid or innerspring. For moderate hot sleepers, gel foam may be sufficient. For heavy hot sleepers, hybrids are a stronger choice.

Are hybrid mattresses good for hot sleepers?

Yes. Hybrid mattresses are one of the best choices for hot sleepers because the coil layer creates natural ventilation that all-foam mattresses can't replicate. Pair that with gel or cooling foam comfort layers and you get the best of both worlds.

What makes natural latex good for summer?

Latex is an open-cell structure by nature — air moves through it easily. It also doesn't conform as deeply as memory foam, so there's less surface contact and less trapped heat. Natural latex mattresses consistently rank among the coolest-sleeping options available.

Can a mattress topper help with cooling?

A cooling mattress topper (latex or gel foam) can improve a hot mattress's performance somewhat. It won't fully fix a dense memory foam mattress, but it can make a meaningful difference. Consider it a bridge option if you're not ready to replace the mattress entirely.

Is a higher price always better for cooling performance?

Not always. A well-built innerspring at $600 can sleep cooler than a $1,500 all-foam mattress with gel marketing. Focus on construction type first (coils vs. foam), then material quality, then price.

Do cooling mattresses have downsides?

The main ones: some use phase-change covers that require specific care, gel foam can be firmer than standard foam, and premium cooling mattresses tend to cost more. Trade these off against the sleep quality improvement for hot sleepers — for most, it's worthwhile.

How long do cooling mattresses last?

Quality cooling mattresses last 7–10+ years. Natural latex tends to last the longest. Hybrid mattresses with quality coil systems typically outlast all-foam beds. Budget gel foam mattresses may soften or lose performance in 4–6 years.
