Don't sleep on these 4th of July mattress sales: Up to 40% off Nectar, Casper and Purple

The most affordable of our 2024 picks is this spring and foam hybrid mattress from Flash Furniture. It comes in two thicknesses (10-inch and 12-inch) and has a soft knitted fabric top that almost mimics the feel of a plush mattress topper (so you technically don't need to buy one — cha-ching!). Oh, and it's currently 41% off on Amazon.

"I just had the best night's sleep that I've had in a long time," one rested, raving reviewer wrote. "I highly recommend this mattress."

Here's another memory foam-spring hybrid that's a bit more customizable and, best of all, breathable. With six sizes (twin to California king) and seven thicknesses on offer, here's your chance to build the perfect accompaniment to your sleeping style. The real star of the show, though, is its breathable knitted fabric cover, which helps enhance airflow circulation and push away body heat so you won't wake up a sweat-sodden mess.

"I purchased it for my daughter, and I find myself sneaking in her room to lie down for a while," this mom wrote about this Amazon favorite.

If medium to medium-firm is your foundational preference, this hybrid may be just your speed. It's supported by pocket spring and high-density memory foam, and shoppers have cited its low motion transfer (meaning you'll be minimally disturbed by a tossing-and-turning bedmate), breathability and hypoallergenic materials.

"This bed will have you sleeping in," predicted this emphatic reviewer. "Don't hesitate, just buy it!"

When over 32,000 reviewers give a mattress a glowing five-star review, we have to give it a look. And we're glad we did, because this crowd-pleaser is a little over 30% off at Amazon right now. This cooling gel memory foam mattress comes in six sizes and, in addition to its breathability, shoppers say it's pressure- relieving.

"I am waking up with zero hip or shoulder pains," one over-the-moon customer wrote. "My arms aren't going to sleep overnight. I don't need caffeine in the morning. Just like that, this mattress has improved my life 1000%."

This medium-firm memory foam mattress has the benefits of old-school materials like latex and memory foam without the sinking and heat retention. It's simple, but somehow has features like pressure relief, breathability and built-in support that actually last for years. "Great sleep isn't complicated — and shouldn't be expensive," the brand says and we couldn't agree more.

"Immediately upon falling on the bed for the first time, I was satisfied," one five-star reviewer wrote. "I have had excellent sleep since purchasing this mattress. I've slept on it for about a month and haven't stopped loving it yet."

Casper is one of today's leading mattress brands and, based on shoppers' reviews, we see why. The Sleep Element checks a whole lotta boxes: It's made of body-molding memory foam, is cooling, supportive, durable and lightweight. It even has a base foam later that's made specifically to prevent sinking and sagging while keeping you supported. 

"I went through five major-brand beds," wrote this giddy Goldilocks. "I was still waking up with pain. I spent two weeks with my friend who had this bed. I came home [and] bought the exact one. I love it. No more pain when I wake up, thank God."

Now, this is what we call a serious steal. Nectar is another tried-and-true mattress brand for so many folks and this one has a breathable cooling cover, gel-infused memory foam, a shift-resistant lower cover and more features that actually serve a purpose. Best of all, though, it comes with a forever warranty!

And oh yeah: It has over 42,000 five-star reviews! Turns out simplicity + quality = a winning formula. "I have the Nectar queen in its most basic form and I love it," one reviewer explained. "This mattress keeps my lower back soreness at bay. When I spend a night at my girlfriend's or in a hotel, my back does not feel the same the next morning."

Another medium-firm standout, this one uses cooling gel and heat-conducting graphite to make one of the most breathable surfaces ever, a big plus for those or you who run a little hot. "We've been T & N lovers for over 10 years," testified a couple of devotees. "These mattresses can't be beat for their comfort and build quality. Absolutely world class." 

Looking for a pressure-relieving option that's also super supportive? This one has three layers of breathable foam that's made for this exact reason. The One is known as the mattress that put Casper on the map, but it's been upgraded with features like cooling foam, a bouncy feel and more. Casper even says it's its "best all-foam mattress," and over 15,000 shoppers agree.

"My husband and I have had our Casper mattress for about five years now, and we couldn't wait to get back home after being away from it," shared this slumberjack. " We are all sleeping so soundly again."

This grid and foam mattress has a durable support base and since it's made with the brand's GelFlex Grid, it immediately adapts to any sleep position and hugs your pressure points. Purple claims it's up to two times cooler than its leading mattress competitors. We're certainly loving this particular perk: If you order now, it ships free in one to two days.

"I have never slept better in my life," a relieved reviewer wrote. "I used to wake up with back pain every morning because of my mattress, but now I can't remember the last time I woke up with a sore back."
