The Best Mattress Topper Award goes to the bed topper that's best at improving the feel, quality, and lifespan of your mattress — which can ultimately save you hundreds of dollars.

Choosing a winner was difficult this year as many premium mattress brands (including Naturepedic, Helix, and Saatva) have launched mattress toppers to offer their signature luxury for less. However, Tempur-Pedic's Tempur-Adapt + Cooling Mattress Topper was the only one to completely transform our beds, making it a worthy recipient of the Best Mattress Topper Award.

The mattress topper on top...

You know a mattress brand is doing right by their toppers when they use the same trademarked material they use in their mattresses. And Tempur-Pedic does just that with their Tempur-Adapt + Cooling Mattress Topper.

A cooling upgrade of their original Tempur-Adapt Mattress Topper, the Tempur-Adapt + Cooling upgrade is a 3" soothing slab of Tempur-Material (Tempur-Pedic's proprietary NASA-developed foam) that's used in their iconic body-hugging mattresses.

We love the premium mattress toppers of rival brands Saatva and Helix, but two things give the Tempur-Adapt + Cooling Topper an edge. First, the ultra-plush foam that provides a marshmallow-soft replica of a luxury Tempur-Pedic bed for less; and second, the cooling, removable, and washable cover which envelopes that cradling foam, complete with anchor straps.

Yes, the Saatva High-Density Foam Topper uses organic, antimicrobial materials found in Saatva's hand-crafted mattress collection, while Helix's mattress toppers typically include the specialist cooling GlacioTex covers found in the brand's Elite mattress collection.

However, Saatva's topper covers are non-removable (plus, toppers are rarely included in the Saatva mattress sales) while Helix's cooling covers aren't washable and are notoriously slippery.

The Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper, meanwhile, is easy to keep clean as you can put the cover in the washing machine. Plus, while it does replicate the pressure relief of Tempur-Pedic mattresses, the cooling cover upgrade, which features cooling yarns woven in, eliminates the heat-trapping tendencies that those beds are notorious for.

Overall, we thought it was the ideal mattress topper for side sleepers and softening hard beds, with its ideal mattress topper thickness providing cushioning to shoulders and hips. You can also frequently find 30% to 40% discounts in the Tempur-Pedic mattress sales, where you can often buy a queen reduced from $429 to $311.40 at Tempur-Pedic. Right now you can get that discount by adding the code TOPPERS at check out. Plus, you'll always find a 10-year warranty and free shipping.

However, there are some drawbacks. It should be obvious from the benefits above, but the Tempur-Adapt + Cooling Mattress Topper above is not for soft beds that you want to make firmer or for back or stomach sleepers that need extra support.

There's also no official sleep trial and the topper can only be returned if it is damaged at delivery or has a product defect.

However, you can find a way around the restrictive return policy when you buy the Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper at Amazon, where you can return the topper in its original condition for a full refund or replacement within 90 days of receipt.
