Best Labor Day mattress sales 2023: Serta, Casper and more

You may not know this, but Labor Day weekend is the perfect time to buy a new mattress. Maybe it's the changing season or that back-to-school refresh in the air. Or, perhaps it's because there are major markdowns, including a top-rated Molblly 10-inch Queen for just $190 (down from $263). Beloved direct-to-consumer brands are offering deep discounts, too — you can get $200 off Purple's top-selling queen mattress and $500 off Temper-Pedic's cooling options.
