Mattress summary: Combining a dynamic airflow system with a breathable surface and ceramic cooling gel, it is no wonder the ClimateCool mattress is one of the best cooling mattresses and best smart beds on the market. It is a more affordable option compared to Sleep Number's premium Climate360 smart bed, which sets you back $10,248 for a queen size at MSRP. The ClimateCool features cooling technology, sleep tracking and the brand's signature adjustable firmness at a fraction of the cost, making it a strong choice for year-round hot sleepers looking for state-of-the-art cooling technology at good value. It offers dual active cooling, meaning it responds to the temperature needs of each sleeper on each side of the bed — good news for couples with different needs. The ClimateCool starts in a queen size, costing $4,598.40 with the current 20% discount (was $5,748). 

Benefits: 100-night sleep trial | 15-year warranty

Price history: The ClimateCool smart bed launched in October 2024 with a queen size retailing at a lower MSRP of $5,499 and we saw this 20% discount in a limited-time Veteran's Day deal. But since the smart mattress's MSRP has now increased, it's great to see this discount return for the new year, letting you save up to $2,049.60 on this exceptionally cooling smart bed. That's a huge saving, and well worth taking advantage of.
