Memory foam mattress toppers are great at softening hard beds, but some trap heat. The Tempur-Adapt + Cooling Mattress Topper, now $309 (was $429) at Tempur-Pedic, is unique in how it pairs bed-softening plushness with effective cooling tech.

It's like a miniature version of the Tempur-Adapt Mattress, but with a key difference: it has a specialist cooling cover that quickly wicks away excess heat.

To me, the Tempur-Adapt + Cooling Mattress Topper is an excellent stop-gap if your current bed is too hard and too warm, but you don't have the budget to upgrade to a proper cooling bed just yet (although there are several good options in the 4th of July mattress sales). Here's a closer look at the Tempur-Pedic 4th of July mattress topper deal...

Astronaut-worthy pressure relief and cooling

The Tempur-Pedic Tempur-Adapt + Cooling Topper delivers the same cloud-like, body-cradling plushness as the original Tempur-Adapt Mattress Topper but without the heat build-up.

Inside the removable cover lies 3" of the brand's trademark Tempur material, allowing sleepers to experience premium pressure-relieving comfort for a fraction of the cost of a full mattress.

The key upgrade is a cool-to-the-touch performance fabric cover that replaces the standard high-stretch knit. This single modification successfully kept testers cool and dry all night. In fact, a main tester prone to regular night sweats reported that the topper exceeded her expectations, preventing her from waking up sweaty a single time.

The cover is also removable and machine-washable for an easy clean. It also sports anchor straps, ensuring the topper stays put on your bed. Overall, this plush mattress topper suits side sleepers the best, cushioning key pressure points, and is a top choice if you want to soften a hard bed.

The Molecule CopperWell Mattress Topper review was so glowing that we decided to name the CopperWell the coolest mattress topper. It's great for side sleeping, too, as it has a zoned design that provides comfort and support where their needed the most. Over $100 cheaper than the Tempur-Adapt + Cooling, the CopperWell Mattress Topper is 30% off with code JULY4. This code takes a queen down from $249 to $175.
