After slogging through a year of the pandemic, you deserve a better night's sleep. A new mattress could help that endeavor. The biggest mattress brands, from Amerisleep to Zoma, are running spring sales with big discounts. Whether you'd prefer form-fitting memory foam, a springy traditional mattress or a best-of-both-worlds hybrid option, there's a deal to match your sleep style. 

Not sure what kind is best for you? Some of these retailers are beefing up their offers with 100-day return policies. That way, if it turns out you aren't getting as good of a night's sleep as you'd hoped, they'll come and take the mattress back and issue a full refund.

We've compiled the best mattress deals out there into our list below. Each of them can be bought online, so you don't need to brave the brick-and-mortar crowds. We'll keep things up to date with the latest and greatest, as well as any new offers that come along.
