The Serta EZ Tote is made with gel memory foam to boost breathability and pressure relief during sleep, and it could be the best mattress for you if you have a smaller amount to spend and want to get as much cooling comfort as possible this summer and beyond. Serta has another popular cheap mattress on sale too: the Perfect Sleeper mattress. You can save 10% on this one too, with a queen size reduced to $629.10 (was $699) (opens in new tab). Serta hasn’t launched its official 4th of July mattress sale yet, so if you’re ready to buy now, you’re looking at savings of up to $800 on a selection of its hybrid and memory foam mattresses in this latest mattress sale. You’ll have 120 nights to trial either Serta mattress, with a 10-year limited warranty in place. You’ll also get free shipping and returns, should you change your mind about the mattress during the trial period. While both of these cheaper Sertas use gel foam to boost breathability, we wouldn’t recommend either if you sleep very hot or are prone to hot flashes (flushes) or night sweats. In that case, and while still keeping prices low, we’d recommend checking out our Cocoon by Sealy Chill mattress review - it’s one of the best cooling mattresses in America right now, and a queen size costs $799, plus you get free cooling bedding with it. For a much plusher and cooler Serta memory foam mattress, take a look at the highly rated iComfort (also available in a hybrid version). You can save $100 on the iComfort (opens in new tab) when purchased alone, or up to $800 when you buy it with a Serta Motion Perfect Adjustable Base. The 10” iComfort uses Serta’s own mattress-cooling foam tech for better temperature regulation, with a Cold Touch Cover up front. A queen size costs $1,199 (was $1,299), putting it in the mid-range for cooling mattresses. All Serta beds are made with toxin-free foams, and you’ll have four months to trial them at home to ensure the one you pick is right for your sleep.
