So you're ready to ditch your lumpy old mattress for a newer, more comfortable model, huh? (Hello, memory foam.) If you don’t feel like fighting off the crowds while shopping at your local mattress outlet, there are plenty of great online deals you can take advantage of—and you don't have to sift through a thousand reviews to find the best one. Check out our buying guide to the three comfiest mattresses on the market right now from Leesa, Allswell, and Linenspa.

1. Leesa’s Universal Adaptive Feel Memory Foam Cooling Mattress

Leesa, Amazon

Do you kick off the covers in the middle of the night because you get too hot? Try Leesa’s 10-inch-tall cooling mattress. It has three unique foam layers: The first layer is designed to keep you cool, while the second offers body-contouring comfort, and the third helps relieve pressure and provide core support. The “adaptive feel” label refers to the fact that it adapts to your body no matter what your preferred sleeping position may be. The mattress comes in twin through California king sizes, with prices starting at $425.

Buy it on Amazon or from Leesa's website.

2. Allswell’s Luxe Hybrid Mattress

This extra-thick mattress is so popular that it frequently sells out from Allswell and at other retailers. It packs 12 inches of high-end material into one mattress, including quilted memory foam and an outer layer designed keep you cool in hot weather. Similar mattresses tend to go for thousands of dollars, but the Luxe Hybrid retails for far less. Prices start at $345 for a twin, $545 for a full, $685 for a queen, or $845 for a king. (Not sure about the difference in mattress sizes? We've got you covered.)

Buy it from Allswell's website or at Walmart starting at $345.

3. Linenspa’s memory foam and innerspring hybrid mattress

Linenspa, Amazon

Amazon customers swear by Linenspa’s hybrid mattress, which comes in sizes twin ($100) through California king ($200). Ideal for people who like medium-firm mattresses, it combines the benefits of memory foam with the support one gets from a traditional innerspring mattress. The standard version is 8 inches thick, but Linenspa also offers a 10-inch version in all sizes. (We also love the company's incredibly affordable down-alternative duvet, which is only $30 on Amazon.)

Buy it on Amazon, where the 8-inch queen mattress is regularly on sale for up to 20 percent off. It's just $170 right now.
