Best Mattresses for Hot Sleepers: Stay Cool All Night

Do you wake up feeling overheated or sweaty? If so, you're not alone. Many people are hot sleepers—and your mattress could be part of the problem. Certain materials trap heat, while others help you stay cool.

In this guide, we’ll explain the best materials for hot sleepers, compare latex vs. memory foam, and explain why cooling covers and hybrid designs matter. Plus, we’ll showcase top cooling mattresses like Helix, Bear, Birch, Nolah, and Leesa—all available to try at The Online Mattress Store here in Green Bay.

Why Some Mattresses Sleep Hot

Traditional memory foam traps heat. Modern mattresses solve this using open-cell foams, cooling covers, coil systems, and natural materials like latex to promote airflow and draw heat away from your body.

Memory Foam Breakdown :

Feature	Traditional Memory Foam	Open-Cell Memory Foam	Gel Memory Foam	Copper Memory Foam
Material	Closed-cell polyurethane	Open-cell polyurethane	Polyurethane + Gel beads/substance	Polyurethane + Copper particles
Temperature Regulation	Retains heat	Better airflow, cooler	Absorbs/dissipates heat, cooler	Draws heat away, cooler
Pros	Pressure relief, motion isolation	More breathable, pressure relief	Cooler sleep, more responsive	Antimicrobial, cooling, allergy relief

Memory Foam: The core challenge of traditional memory foam's heat retention has led to the development of alternative solutions. Open-cell memory foam tackles this by creating a structure of interconnected air pockets, allowing heat to dissipate through improved airflow. Gel memory foam incorporates gel beads or a gel-like substance, which actively absorbs and releases heat. Similarly, copper memory foam utilizes the thermal conductivity of copper particles to draw heat away from the body. Beyond cooling, gel often enhances responsiveness, while copper offers antimicrobial properties and potential allergy relief.

Latex : Latex mattresses are also great for hot sleepers due to their naturally cooling properties. Unlike other materials like memory foam which can trap heat, the open-cell structure of latex allows for superior breathability and continuous air circulation within the mattress. This effectively dissipates body heat and moisture, preventing heat from getting trapped, and maintaining a comfortable sleep temperature. Additionally, latex naturally wicks away moisture, which further enhances the cooling effect and helps prevent night sweats.
