These are the best 4th of July mattress sales from Sealy, Serva, Nectar, Casper and more

Is there anything better than a good night's sleep? Nope. Nearly 6,000 Wayfair shoppers gave this Sealy favorite — now an awesome 65% off for July 4 — five stars. The foam mattress is layered with gel and memory foam for custom support, distributing weight evenly and relieving pressure points. 

Rest easy knowing all Sealy foams in this mattress meet CertiPUR-US safety standards. It's delivered in a box right to your door for easy setup. 

Serta has been around for more than 90 years, and the brand has used that depth of experience to create some pretty innovative mattresses. The iComfort comes in four thicknesses and three firmnesses, and all versions include a 1-inch-thick layer of memory foam infused with graphite, which has naturally cooling properties.

Psst: You can save up to $325 on the entire iComfort line, courtesy of the brand's 4th of July sale.

This 14-inch fave gets high marks for a plush, soft feel and a surprisingly low price. Made from cooling-gel memory foam atop a layer of traditional pocketed coils, it's also Wayfair-verified, which means it passes a 20-point quality inspection. Skeptical? There's a 100-night trial.

"If you didn't know the brand and price ahead of time, you would think it was easily an $800-$1,000 mattress," said one budget-savvy buyer. "Although very plush, it still supports my entire body (220 pounds) evenly, and I have been sleeping soundly and waking up rested each day."

Not sold on foam? Don't worry: Here's a no-fail $300-off option for innerspring lovers, with two thick coil layers and a cushy pillow top. It comes in three firmness levels, with the middle-of-the-road "luxury firm" designed to "replicate the feel of hotel beds." (Wish it came with room service too!)

"Highly recommended, and I'm quite a diva," admitted one discriminating buyer. "I hold every company I deal with to what they have promised. My husband has chronic pain, and honestly, I usually complain about everything. This mattress is great."

Get ready for some savings fireworks: Thanks to the brand's 30% off sitewide July 4th sale, you can snag this sleeper from Brooklyn Bedding for under $500 with code JULY30. Unlike other budget-friendly beds, it's not a basic slab of foam — it has six layers designed to minimize pressure points, eliminate motion transfer and keep your spine aligned. It's backed by a 120-night trial, and a hybrid version is on sale too.

"This mattress is amazing. Me and my husband struggled with waking each other up, and this bed does NOT move (which is a good thing)," a reviewer raved. "Very comfortable and cooling, but not too cold!"

Another retailer offering a celebratory 30%-off discount this Independence Day is Casper — and first-time customers can get an additional 5% off too. Inside this 12-inch hybrid are two breathable foam layers atop a traditional innerspring base. The foam is designed to be softer up near the shoulders and more supportive from the lower back on down — great for minimizing those aches and pains. There's also a 100-night, risk-free trial. 

"They say it takes weeks to adjust to a new mattress, but after only a few nights I could honestly cry with relief," said one now-solid sleeper. "Only now, waking up pain-free, do I realize how much my previous mattress was hurting me. If you're a side sleeper, if you toss and turn or wake up from lower back pain, do yourself a favor and get the Dream. The firmer center band keeps you from sinking in, keeping your spine aligned and eliminating lower back pain."

Nectar's 4th of July deals are among the absolute sweetest we've seen. You can snag up to half off mattresses and 66% off mattress and bed frame bundles, including major savings on this 12-inch foam pick. It's topped with a cooling cover too, and backed by a particularly impressive 365-day trial. (That's right — you get a whole year to make a final decision.) It has a medium-firm feel that reviewers say is hard to beat, especially for those with back pain.

"Coming up on three years and still going strong," says one longtime owner. "The no-motion transfer is a game changer. I never feel my husband jump (turn) over at night, and it's also the perfect firmness. Not too hard and not too soft. I’ll never buy another mattress."

This luxury hybrid is made with more natural materials, including wool, natural latex, cotton and steel coils. Wool is temperature-regulating, so you won't sweat as you sleep this summer. And the separate layers of latex cradle your body while reducing stress on your lower back. You'll enjoy 25% off sitewide and two free pillows (a $149+ value!) at Birch's Fourth of July sale using code JULY25.

"I absolutely love this mattress," said a shopper. "I love that it's nontoxic, and it's super comfy. I sleep like a baby, best sleep ever. Not too soft and not too firm, it's right in between. This is the only mattress I recommend 100%."
