If your bed is prone to trapping heat during summer heatwaves, then you may want to invest in a cooling mattress topper. Luckily, right now you can buy a Gel Memory Foam Mattress Topper from $44.99 with code SAVEDCART10 at Lucid Mattress— and a queen is just $62.99.
And there's more deals where that came from, as many of the best mattress toppers are equipped with temperature-regulating features designed to refresh any hot and stuffy beds. Some even feature the specialist cooling tech found in this year's best mattresses.
Ahead of this year's Amazon Prime Day mattress deals, many brands are putting out mattress topper discounts that rival the retail giant's. So, I've rounded up 5 of the best cooling mattress toper deals from around the web that beat the heat and Amazon's current prices.
