Memory foam mattresses provide excellent body-cradling comfort but they can feel a little stuffy when summer arrives.

Luckily, there are plenty of cooling mattress toppers on sale right now to cool things down, including a chance to save 20% on the TEMPUR-Adapt + Cooling Topper at Tempur-Pedic.

The TEMPUR-Adapt + Cooling Topper is actually a cooling upgrade from the original Tempur-Adapt Topper, currently No 1 in our best mattress toppers of 2025 guide. But there are plenty more cooling bed toppers on the market, from brands such as premium Helix and budget-favorite Lucid.

All three cooling mattress toppers below have been tried and tested by us, a team of sleep experts, so we know they actually work and are worth buying in this weekend's mattress sales to get ahead of the heatwaves.

Comfy cooling

1. Tempur-Adapt + Cooling Mattress Topper: queen was $429 now $359 at Tempur-Pedic
While we rated the original Tempur-Adapt Topper as the best memory foam mattress topper of 2025, we did find it retained heat. Enter the Tempur-Adapt + Cooling Mattress Topper, the Tempur-Adapt Topper's cooling upgrade. The upgrade is $60 extra, but it should be a worthwhile extra if you overheat at night. In our Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper review, our tester didn't experience night sweats once on this topper, and found that its body-cradling foam is perfect for side sleepers. In the current Tempur-Pedic mattress sale there's 20% off the Tempur-Adapt and Tempur-Adapt + Cooling toppers, making the starting price of a twin-sized Tempur-Adapt + Cooling $279 (down from $329). Unfortunately, there's no official sleep trial, but you will get a 10-year warranty and free shipping.

Luxury cooling

2. Helix Premium Mattress Topper with GlacioTex: queen was $498.66 now $364.03 with code TOMS27 at Helix
The Helix Premium Mattress Topper with GlacioTex contains two stand-out features: a layer of micro-coils (small springs made for bed toppers) and a cooling GlacioTex cover. While the micro-coils offers support and comfort, the GlacioTex (a specialist cooling fabric used in the best cooling mattresses) provides a heat-dissipating surface. Our Helix GlacioTex Premium Mattress Topper review team praised its cool-to-the-touch cover and the softness it provides without being stuffy. While there's a 25% off Helix mattress sale (usually 20% off), you can score a 27% discount with code TOMS27, bringing a twin-size to $272.54. Benefits include a 100-night sleep trial and free shipping.

Budget cooling

3. Gel Memory Foam Topper: queen was $69.99 now $55.99 with at Lucid
Coming in 3 different heights (2", 3", or 4"), the Lucid Gel Memory Foam Mattress Topper offers impressive cooling for such a low price. Testers slept comfortably cool no matter the temperature outside when using the Lucid Topper and it's all thanks to its gel-infused ventilated design. A 20% discount is automatically applied to your cart when you add a Lucid topper and you'll get a 30-night sleep trial, free shipping, and a 3-year warranty. The price increases with height (we tested the 4" version for our Lucid Gel Memory Foam Mattress Topper review), so you can get a two-inch thick twin-size for as low as $39.99.
