In an ideal world, you should snooze for seven or more hours per night, according to the CDC. But even if you turn in at a reasonable hour (and power down your devices), an uncomfortable mattress could disrupt how many hours you actually slumber. Designed for real-life problems like night sweats, Idle Sleep’s memory foam gel mattresses stay cool — and are also surprisingly affordable.

Now, during Idle Sleep's Summer Sale, you can choose between two great deals: save 20% off any mattress, including memory foam gel, eco latex, and pure hybrid options, or receive a free adjustable base with a mattress purchase.

Among Idle Sleep’s full range of mattresses, the most wallet-friendly picks are the standard, 12-inch Idle Gel Foam (normally $449-$749) and the 14-inch Idle Gel Plush (normally $799-$1,499), offering luxurious softness. Both feature medium support and toxin-free, Aircell gel memory foam.

Look for cooling materials

Toss and turn on muggy nights? When you’re too warm, it’s difficult to fall sleep because body temp plays a role in restful sleep (in other words, you really do need to chill out). For sound slumber, Idle Sleep’s memory foam features layers of gel cooling technology to promote air flow — in both the Idle Gel Foam and Gel Plush models.

Make sure you love it before committing

Test out any of Idle Sleep mattresses to see if it’s right for you with a risk-free, 18-month trial period. If it’s not the one, you can easily return it without any hassle or awkward conversation. You don’t even need to give a reason.

Take advantage of a lifetime warranty

For extra durability, Idle Sleep uses sink hole-free memory foam and a 2.4-pound base instead of the industry standard of 1.8 pounds. But, if anything goes wrong, the “warranty without end” covers pretty much everything — even body impression.
