Sleep Number

New York – October 16, 2026 -- Hot sleepers who wake up sweaty at 3 a.m. have a new mattress to consider: Expert Consumers has named the Sleep Number ClimateCool a top choice in its review of the best cooling mattresses, citing up to 15 degrees of active cooling on each side of the bed.

Airflow removes heat instead of just feeling cool

The 12-inch ClimateCool moves air through the bed to carry warmth away from the body. Cooling gel layers and breathable materials support that airflow. Many cooling mattresses rely on breathable covers or cooling foams alone, which can make the bed feel cooler but do not keep removing heat as the night goes on, according to the review.

New York – September 25, 2026 -- Consumer365 has named Sleep Number the best mattress brand for couples in its 2026 review, citing the ability for each partner to set a different firmness level on their own side of the bed. Every Sleep Number mattress in queen size or larger includes this feature, letting one person choose a softer feel while the other selects firmer support.

The review highlights ComfortMode Lux as its top pick for couples and singles out ClimateCool for pairs where one partner sleeps hotter than the other.
