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.
Not all "cooling" mattresses are equal. There are four real mechanisms that reduce heat retention:
Bottom line: if you sleep hot, a hybrid or innerspring mattress will outperform any all-foam mattress regardless of what the foam marketing says.
| 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 |
The top-of-the-line cooling choice. Tempur-Pedic's ProBreeze line is purpose-built for hot sleepers — with a cool-to-touch zip-off cover, a PureCool+ phase-change material layer that actively draws heat away from your body, and TEMPUR-CM+ foam that enhances breathability throughout. The hybrid construction adds pocketed coils underneath for airflow and support.
| Pros | Cons |
|---|---|
| Best-in-class cooling technology | Premium price point |
| Excellent pressure relief and support | May be too firm for comfort-first sleepers |
| Durable; long lifespan |
A strong mid-range option that covers multiple bases: copper-infused foam for temperature regulation and antimicrobial properties, MoistureProtect cover that wicks sweat, and Posturepedic's targeted lumbar support. The plush feel suits side sleepers well. The hybrid construction keeps the base breathable.
| Pros | Cons |
|---|---|
| Effective cooling and moisture control | Plush feel may not suit back/stomach sleepers |
| Targeted lumbar support | Higher price than basic hybrids |
| Good for multiple sleep positions |
If you want foam performance with better cooling than standard memory foam, Technogel is worth knowing. The gel layer is different from typical gel-infused foam — it's a softer, more responsive material with genuine heat-dissipating properties. Good for back and side sleepers who want contouring without the heat trap.
| Pros | Cons |
|---|---|
| Better cooling than standard memory foam | Premium price range |
| Targeted pressure relief | May feel firm to some |
| Good for back and side sleepers |
Natural latex is inherently cooler than memory foam — it's an open-cell structure that breathes naturally. The Harvest Green line uses organic cotton covers and eco-certified materials, making it the best choice for hot sleepers who also want a sustainable mattress. Firm feel is ideal for back and stomach sleepers.
| Pros | Cons |
|---|---|
| Naturally breathable and cool | Firm — not for side sleepers or plush preference |
| Organic and eco-friendly | Higher price point |
| Very durable |
A plush innerspring with gel-infused memory foam comfort layers. The Diamond Envoy's pillow-top softness suits side sleepers, while the innerspring base keeps airflow solid. Gel foam draws heat away from the surface. A reliable mid-range option for hot sleepers who need cushioning.
| Pros | Cons |
|---|---|
| Plush feel with good cooling | May be too soft for stomach sleepers |
| Good motion isolation | Some initial off-gassing possible |
| Solid price-to-performance ratio |
Gel-infused foam with a breathable design at a solid value. Best for side sleepers who run warm. The Englander Grenadier is a good entry point into cooling mattress territory without the premium price tag of the Tempur-Pedic or Sealy Copper lines.
| Pros | Cons |
|---|---|
| Good cooling at accessible price | Too soft for back/stomach sleepers |
| Great for side sleepers | Some initial off-gassing possible |
Classic innerspring airflow with a plush pillow top. The Eastman House Spruce is straightforward: coil-based airflow, a comfortable pillow top, and a breathable cover. Good for sleepers who want traditional feel and reliable cooling without complex foam layers.
| Pros | Cons |
|---|---|
| Excellent airflow from innerspring base | Less pressure relief than foam options |
| Comfortable plush top | May feel too bouncy for some |
Use this framework to narrow it down:
Even with a great mattress, a few other factors matter in LA summers:
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.
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.
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.
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.
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.
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.
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.
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.
