If you're a side sleeper prone to overheating, and who needs to soften up a hard bed, a soft and cooling mattress topper is the ideal solution. Our favorite is the Tempur-Adapt+ Cooling Topper, up to $160 off at Tempur-Pedic when you use the code TOPPERS at checkout.

The Tempur-Adapt + Cooling is the best mattress topper we've ever tested, which isn't surprising considering it's made by the brand behind some of the best mattresses for all sleepers. This secret discount code drops the price of a queen size Tempur-Adapt+ Cooling Topper to $319 (was $439), making it a cost-effective way to experience the signature cooling comfort of a Temur-Pedic bed for less.

While this month's mattress sales aren't bringing the big savings that we'll likely see in next month's holiday sales, this new Tempur-Pedic deal is excellent value.
