The Biggest Fourth of July Mattress Sales to Shop Online Right Now

Helix Midnight Luxe Mattress ($1,780, originally $2,374)

Helix is celebrating the Fourth of July the right way — aka by hosting a major sale that gives us an excuse to splurge on all of the mattresses we've long been coveting. The brand is offering 25 percent off sitewide, plus 30 percent off on Luxe and Elite mattress collections and two free pillows with any mattress purchase. We love this model in particular because it comes equipped with a premium pillow top (for extra cushioning), boasts a medium firmness, and is best for side sleepers — per the brand.

One reviewer on Helix's site raved about the mattress, saying: "Simply amazing. Greatest mattress I have ever owned. When you work as hard as I do, it is the most relieving experience to come home to a cool, comfortable, and customized mattress. Extremely happy customer!"
