01Best Cooling Mattresses for Summer

Heat is one of the most common reasons people wake up at night. Your body needs to lower its core temperature to stay in deep sleep — and a mattress that traps heat works directly against that process. In LA and Southern California, where summer temperatures stay elevated well into the night, sleeping on the wrong mattress can mean months of disrupted sleep.

This guide reviews the best cooling mattresses available at LA Mattress Store, explains what cooling technologies actually work, and helps you match a mattress to your sleep style.

03Quick Answer

The most effective cooling mattresses use natural latex or gel-infused hybrid designs with breathable covers. For eco-conscious shoppers: the Harvest Green latex. For advanced temperature technology: the Tempur-Pedic TEMPUR-Probreeze. For budget-friendly options: the Envoy by Diamond or Spruce by Eastman House.

04How Cooling Mattresses Actually Work

Not all cooling claims are equal. Here's what the different technologies actually do:

  • Natural latex: Open-cell structure allows constant airflow through the mattress. One of the best passive cooling options available.
  • Gel-infused foam: Gel absorbs body heat and disperses it away from the sleep surface. More effective than standard memory foam, but still less breathable than coil-based designs.
  • Phase change materials (PCM): Active technology that absorbs heat when your body is too warm and releases it when you're cool. Found in higher-end options like Tempur-Pedic.
  • Copper-infused foam: Copper is a natural conductor that pulls heat away from the body. Also has antimicrobial properties.
  • Innerspring / pocketed coils: The air gaps between coils allow heat to dissipate naturally. Hybrid mattresses combine this with foam comfort layers.
  • Breathable covers: Moisture-wicking fabrics (organic cotton, Tencel, stretch knit) help surface-level cooling and prevent that sticky feeling.

05Who Needs a Cooling Mattress

You'll benefit most from a cooling mattress if you:

  • Wake up sweating or feeling hot during the night
  • Sleep with a partner who generates significant body heat
  • Live in a warm climate or don't use air conditioning overnight
  • Currently sleep on an all-foam mattress that feels like it traps heat
  • Experience night sweats from hormonal changes or medications

If you sleep cold: These mattresses won't make you uncomfortable, but you may not need their cooling features. A standard mattress at the right firmness level is usually sufficient.

06Top Cooling Mattress Picks

1. Harvest Green Original Firm Natural Latex by Diamond Mattress

Best for: Back and stomach sleepers who want eco-friendly cooling without relying on synthetic technology.

The Harvest Green pairs this with an organic cotton cover that wicks moisture and allows surface airflow. No gel, no synthetic cooling agents — just effective passive cooling from the material itself.

Pros Cons
Excellent natural breathability Firm feel — not ideal for side sleepers
Organic, chemical-free materials Higher price than synthetic foam options
Durable — latex holds up for years
Ideal for back/stomach sleepers

2. Tempur-Pedic TEMPUR-Probreeze Medium Hybrid 12"

Best for: Hot sleepers who want the most advanced temperature regulation available and sleep with a partner.

This is as engineered as cooling gets. The TEMPUR-Probreeze uses phase change materials that actively absorb and release heat, a TEMPUR-CM+ layer that enhances airflow, and a SmartClimate Dual Cover that's cool to the touch on contact. The hybrid construction adds innerspring coils for breathability and motion isolation for couples.

Pros Cons
Best-in-class active cooling technology Premium price — significant investment
Excellent motion isolation for couples Medium firmness only — not for firm or soft preference
Hybrid = extra breathability from coils
Backed by Tempur-Pedic's warranty

3. Diamond Technogel Estasi Medium Foam Mattress 12"

Best for: Side and back sleepers who want gel-based cooling with superior pressure relief.

Technogel is a proprietary gel compound that has more cooling capacity than standard gel-infused memory foam. It's softer and more conforming, which makes this mattress particularly good for pressure relief. The medium firmness suits a wide range of sleep positions.

Pros Cons
Superior gel cooling technology Soft feel — may not suit stomach sleepers
Excellent pressure relief and body contouring Premium price point
Medium firmness works for most positions

4. Grenadier Gel Plush Mattress by Englander

Best for: Side sleepers and plush-preference shoppers who also sleep warm.

Soft and cooling — a combination that's harder to find than it should be. The Grenadier uses gel-infused foam to manage heat while the plush comfort layer provides the cushioning side sleepers need for shoulders and hips. Good motion isolation as well.

Pros Cons
Soft and cooling — rare combination May not support stomach sleepers well
Good for side sleepers Durability concerns for heavier sleepers
Effective gel cooling
Good motion isolation

5. Spruce Plush Pillow Top Innerspring by Eastman House

Best for: Budget-conscious shoppers who want solid cooling and a comfortable plush feel.

Innerspring mattresses are naturally cooler than foam because the coil structure allows airflow throughout. The Spruce adds a breathable pillow top for comfort without blocking that airflow. Strong edge support means the full sleeping surface is usable — a practical advantage.

Pros Cons
Natural cooling from coil structure Less pressure relief than foam options
Affordable for the quality Durability may vary with heavy use
Strong edge support

6. Sealy Posturepedic Performance Hybrid Copper II Plush 13"

Best for: Hot sleepers who want copper's active heat-pulling properties in a hybrid design.

Copper is an effective thermal conductor — it actively draws heat away from your body rather than just reflecting it. The Sealy uses copper-infused foam alongside a hybrid coil system and a MoistureProtect cover for a multi-layered cooling approach. Good choice for couples due to excellent motion isolation.

Pros Cons
Copper actively pulls heat away from the body Plush feel — not for firm-preference sleepers
Hybrid = strong airflow from coils Higher price point
MoistureProtect cover aids cooling
Good motion isolation

7. Envoy Gel Plush Pillow Top Innerspring by Diamond Mattress

Best for: Side sleepers who want gel cooling plus the natural breathability of an innerspring at a reasonable price.

Combining gel-infused foam with innerspring coils gives the Envoy two layers of cooling — the gel handles the surface heat, and the coil system handles deeper airflow. The pillow top adds cushioning without sacrificing breathability.

Pros Cons
Dual cooling: gel foam + innerspring airflow May be too soft for stomach sleepers
Plush pillow top for side sleepers Durability may be limited with heavy use
Affordable for gel-hybrid construction

08Tips Before You Buy

  • Don't rely on cooling technology alone: Room temperature, breathable bedding (cotton, Tencel), and a quality mattress protector all affect how cool you sleep. A cooling mattress in a 78°F room will still feel warm.
  • Consider your partner: If one of you sleeps hot and the other sleeps cold, look for a mattress with good temperature neutrality (like latex) rather than one optimized for extreme cooling.
  • Test it first: Cooling properties can be hard to assess from specs alone. Visit one of our showrooms to feel the difference between gel foam, latex, and hybrid options.
  • A cooling topper can help too: If you already have a good mattress, a latex or gel topper can improve breathability without a full replacement.

10Frequently Asked Questions

What makes a mattress cooling?

The most effective cooling mechanisms are: open-cell or coil construction for airflow, gel or copper infusions to draw heat away from the body, phase change materials that actively manage temperature, and breathable covers that wick moisture. Natural latex is one of the best passive cooling options; phase change technology (like Tempur-Pedic's) is the most active.

Do cooling mattresses really work?

Yes — but the degree of cooling varies significantly between models. Marketing claims like "sleeps cool" are applied liberally. Look for specific technologies: gel infusions, coil-based designs, phase change materials, and copper are the most proven. Pure memory foam with a "cooling cover" is the least effective.

Can a mattress topper improve cooling?

Yes. A latex or gel-infused topper can meaningfully improve breathability on an existing mattress. If your mattress is otherwise in good shape but sleeps warm, this is a cost-effective solution before committing to a full replacement.

Is a firmer mattress cooler?

Firmer mattresses typically allow less body sinkage, which means less surface area contact with the mattress — which can reduce heat buildup. But firmness alone doesn't determine temperature. A firm foam mattress without good airflow will still sleep hot. The material and construction matter more than firmness level.

Are cooling mattresses more expensive?

Advanced cooling technology (like phase change materials) does add cost. But several effective options — including the Spruce and Envoy — are priced competitively. Natural latex, which is inherently cooling, falls in the mid-to-premium range but often represents better long-term value due to durability.

How long do cooling mattresses last?

Natural latex: 10–15 years. Quality hybrids: 7–10 years. Foam-based options: 5–10 years depending on density and construction. The cooling properties themselves don't typically degrade separately from the mattress overall.

Do cooling mattresses come with a trial period?

Many do. At LA Mattress Store, we offer a 120-night comfort guarantee — enough time to assess how any mattress performs across different temperatures and seasons.
