Key Features to Look for in a Cooling Mattress for Couples

Temperature Regulation

Temperature regulation is crucial for a cooling mattress. 

Look for mattresses with advanced cooling technologies, such as gel-infused foams, breathable materials, and phase-change materials (PCM). 

These features aren't just fancy terms; they help dissipate heat and keep the mattress cool throughout the night. 

For instance, the SONU Sleep System uses PCM woven into the cover to draw heat away from the sleeper, ensuring a cool surface.

Motion Isolation

Motion isolation is essential for couples to prevent disturbances caused by movement. 

A good cooling mattress should minimize motion transfer, allowing both partners to sleep undisturbed. 

Mattresses like the Tempur Breeze Medium-Hybrid excel in this area, utilizing TEMPUR-Material™ to provide excellent motion cancellation.

Edge Support

Edge support ensures the mattress remains stable and supportive, even when sitting or sleeping near the edges. 

This feature is particularly important for couples sharing a bed. High-quality edge support prevents sagging and extends the mattress's usable surface area.

Firmness Levels

The ideal firmness level depends on personal preference and sleeping position. Some couples may prefer a softer mattress, while others need firmer support. 

The SONU Sleep System offers different firmness levels, including Plush, Hybrid, and Firm, catering to various needs.

Durability and Warranty

A durable mattress is a long-term investment. Look for mattresses made from high-quality materials with robust construction. 

Additionally, a comprehensive warranty indicates the manufacturer's confidence in their product. The SONU Sleep System, for instance, comes with a 10-year warranty, ensuring peace of mind.
