Shopping for a new bed in the 4th of July mattress sales? You might have heard that while it's a good time for discounts, it's not really an opportunity to grab the lowest prices of the year. Well, we have news for you.

Right now in the 4th of July sales you can get two of the best mattresses on the market at all-time low prices. First up is the Cocoon by Sealy Chill mattress, which delivers impressive cooling at a surprisingly low price, and which you'll find in our best memory foam mattress and best cooling mattress guides. It's currently in the Cocoon by Sealy 4th of July sale with 35% off, plus a free set of pillows and sheets worth up to $199 included.

That's a fairly standard Cocoon by Sealy deal right now, but it gets even better: if you use the offer code EXTRA25 at the checkout, you'll get an additional $25 knocked off your bill. That brings the price of a queen size down to just $674, which is an absolute all-time low that you don't want to miss.

We're all used to seeing prices creep up at the moment, but impressively his 10-inch medium-firm memory foam mattress is actually cheaper now than it was in last year's 4th of July mattress sales, and indeed at any other time, when you use the offer code EXTRA25. Its cover is made from phase-change material to regulate your temperature as you sleep, making it an excellent budget option for hot sleepers. With the offer code you can get a queen size for just $674, and you get a bundle of free pillows and sheets worth $179 included.

Not grabbed by that? Then how about the lowest ever price on the best mattress for side sleepers? That, in case you're wondering, is the Helix Midnight mattress, which we also rank as one of the best hybrid mattresses right now.

In the Helix 4th of July sale there's 25% off the Midnight, with two free pillows included. Again that's fairly standard stuff; however, there's been a small MSRP adjustment on the queen size recently, bringing the sale price down to just $999. That's less than it was on sale for on Memorial Day, and in fact that's the lowest price we've ever seen it at. 

If you want a cushioning mattress with plenty of support and pressure relief, you'll want to grab it at this price. And if you'd prefer a bouncier feel rather than sink-in memory foam, the Dusk line has the same design but swaps in a 'latex-alternative' foam. Whichever one you go for, there's the option to amp up the luxury by switching to the 'Luxe' version – head to our Helix Dusk Luxe mattress review for a look at what to expect.
