Best Mattress for Hot Sleepers 2026

If you consistently wake up drenched in sweat or find yourself flipping your pillow to the cool side multiple times per night, you are not alone. Studies suggest that up to 41% of adults report feeling too hot during sleep at some point. The right mattress can be the difference between restless, sweaty nights and deep, refreshing rest. In this guide, we review the best mattresses for hot sleepers in 2026, break down the cooling technologies that actually work, and help you choose the right option for your sleep style.

Why Some Mattresses Sleep Hot

The reason many traditional mattresses trap heat comes down to materials and design. Older innerspring mattresses with thick pillow tops tend to allow airflow, but many modern mattresses—especially those made entirely of memory foam—can trap body heat because they are designed to conform closely to your body, which reduces air circulation around your skin.

Memory foam was originally developed for NASA seat cushioning. Its ability to distribute pressure is excellent, but the dense cell structure that makes it so good at pressure relief also makes it a poor conductor of heat. When manufacturers started building all-foam mattresses in the early 2000s, many sleepers complained about sleeping hot. The industry responded with cooling gel, open-cell foam, and phase-change materials, but not all of these solutions are equally effective.

Key Cooling Technologies Explained

Gel-Infused Memory Foam

Gel particles are mixed into memory foam to help absorb and dissipate body heat. The gel has a higher thermal conductivity than standard foam, which means it can move heat away from your body more effectively. Look for mattresses with gel beads or gel-swirl layers rather than just a thin gel topper, which can make only a marginal difference.

Open-Cell Foam

Traditional memory foam has closed cells, which trap air and heat. Open-cell foam has a structure that allows air to flow through more freely. Some manufacturers use open-cell foam throughout the mattress, while others use it only in comfort layers. Open-cell foam is generally cooler than standard memory foam, though hybrid designs with innerspring coils still outperform it in airflow.

Innerspring Coil Systems

Coil-based mattresses—whether traditional innerspring or hybrid—provide the best natural airflow of any mattress construction. The open space between coils allows heat to escape upward and cool air to circulate. A mattress with individually wrapped (pocketed) coils tends to offer better motion isolation than Bonnell coils while maintaining good airflow.

Phase-Change Materials (PCM)

PCM technology works by absorbing heat when your body temperature rises and releasing it when you cool down. These materials can feel cool to the touch initially and actively regulate temperature throughout the night. Some premium mattresses use PCM in their cover fabrics or comfort layers. Casper's Wave series and Saatva's Latex Hybrid are notable examples.

Copper and Graphite Infusions

Copper has natural thermal conductivity properties and is also antimicrobial. Several mattress manufacturers now infuse copper particles into foam layers to help pull heat away from the body. Graphite behaves similarly. These materials are increasingly common in premium cooling mattresses and tend to be more effective than standard gel infusion.

Our Top Picks: Best Mattresses for Hot Sleepers 2026

1. Saatva Latex Hybrid – Best Overall Cooling Mattress

The Saatva Latex Hybrid combines a 3-inch latex comfort layer with a supportive coil system. Latex is naturally temperature-neutral and sleeps cooler than memory foam. Theencased coil base promotes excellent airflow, and the organic cotton cover adds breathability. This mattress is particularly well-suited for hot sleepers who also want responsive pressure relief without the "stuck" feeling of deep memory foam.

2. Purple Mattress – Best for Pressure Relief Without Heat

Purple's proprietary Hyper-Elastic Polymer grid is unlike any other mattress material. Instead of foam, Purple uses a grid of polymer squares that flex under pressure but allow massive amounts of airflow all around your body. The grid channel's air directly under and around you, creating a cool-to-touch sensation that persists throughout the night. The Purple 4 includes a layer of gel foam for added pressure relief while maintaining excellent cooling.

3. Tempur-Pedic ProAdapt – Best Premium Memory Foam

Tempur-Pedic has long been associated with slow-sinking memory foam, but their latest ProAdapt line includes advanced cooling technologies. The ProAdapt Medium Hybrid combines TEMPUR-ES material (which has an open-cell structure) with a layer of Pure Cool Phase Change Material. The cover is infused with cooling fibers that feel cool to the touch. For hot sleepers who love the hugging feel of memory foam but need better temperature control, the ProAdapt is a strong choice.

4. WinkBed – Best Innerspring Cooling Option

The WinkBed is a zoned coil mattress with a Euro-pillow top that includes a Tencel cover and gel-infused foam layers. The coil unit uses individually wrapped coils that respond independently to pressure, and the zoned lumbar support helps maintain spinal alignment without adding unnecessary material that could trap heat. The WinkBed also comes in a "Softer" option that includes more cooling gel foam for hot sleepers who prefer a plush feel.

5. Casper Wave Hybrid – Best Budget-Friendly Cooling Mattress

The Casper Wave Hybrid features a layer of AirScape perforated foam (which has small holes to increase airflow) and a layer of gel pods designed to pull heat away from the body's densest pressure points—the shoulders and hips. The hybrid construction adds a layer of springs for additional breathability. At under $1,500 for a queen, it is one of the most effective cooling mattresses at a mid-range price point.

How to Keep Your Mattress Cooler for Longer

Buying a cooling mattress is the most important step, but a few additional practices can help you maintain a cool sleep environment:

• Use a breathable mattress protector – Avoid plastic or vinyl protectors that trap heat. Look for protectors made of Tencel, cotton, or cooling-knit fabric.
• Choose the right sheets – Egyptian cotton, linen, and Tencel sheets all sleep cooler than microfiber or sateen cotton. Look for a thread count between 300 and 500 for the best balance of breathability and softness.
• Set your thermostat – The ideal bedroom temperature for sleep is between 60°F and 67°F (15.5°C to 19.4°C). Even a few degrees can make a significant difference.
• Consider a cooling mattress topper – If you already own a mattress that sleeps hot, a gel-infused memory foam topper or a phase-change topper can help, though replacing the mattress entirely is usually more effective.
• Limit bedding layers – Heavy comforters and multiple layers trap heat. Use lighter blankets and add layers only as needed.

Best Mattress for Hot Sleepers: By Sleep Position

Side Sleepers

Side sleepers need a mattress that relieves pressure at the shoulders and hips while allowing airflow. The Purple Mattress and Tempur-Pedic ProAdapt both perform well here. Side sleepers tend to press more of their body surface against the mattress, making cooling technology especially important.

Back Sleepers

Back sleepers benefit from the good airflow of hybrid mattresses. The Saatva Latex Hybrid and WinkBed both provide the lumbar support back sleepers need without trapping heat. A medium-firm feel is generally ideal for back sleepers.

Stomach Sleepers

Stomach sleepers need a firmer surface to prevent excessive sinkage at the hips, which can strain the lower back. A firmer mattress with cooling features—like the WinkBed in its firmer setting—works well. Thinner comfort layers reduce the amount of material between you and the coil layer, keeping you cooler.

Frequently Asked Questions

Do cooling mattress toppers actually work?

Yes, but the effectiveness varies significantly. Gel-infused memory foam toppers can reduce heat retention, while phase-change toppers actively regulate temperature. However, a topper cannot fully compensate for a mattress that fundamentally traps heat. A quality cooling mattress will outperform a great topper on a poor mattress.

Is memory foam always hot?

Not anymore. Modern memory foam mattresses incorporate various cooling technologies that significantly reduce heat retention. Look for open-cell memory foam, gel infusion, copper or graphite particles, or phase-change materials. All-foam mattresses without these features are more likely to sleep warm.

How long do cooling mattresses last?

Most quality mattresses last 7 to 10 years. Cooling properties in foam layers may diminish over time as the foam compresses and loses its cellular structure. Hybrid mattresses with coil systems tend to maintain their cooling properties longer because the coils do not compress or degrade the way foam does.
