I'm a mattress tester — 7 luxury beds I'd buy in the 4th of July sales

1. Stearns & Foster Lux Estate mattress: was from $2,899 now $2,499 + $300 Visa gift care with code 300VISA at Stearns & Foster
The Lux Estate mattress from Stearns & Foster combines strong, supportive coils with soft Tempur-Material foams for a hybrid bed that provide pressure relieving comfort while maintaining sturdy support. While we haven't had a chance to test the Stearns & Foster Lux Estate, we were impressed with the simpler Estate bed in our Stearns & Foster Estate mattress review. You can expect this more expensive version to provide an enhanced level of support and better cushioned comfort. We typically see Stearns & Foster offer $400 off around major sales days, but the rest of the year, this brand isn't known for its deals. Now is a great time to shop, especially as Stearns & Foster has sweeten the deal with a $300 Visa gift card. Just use code 300VISA at checkout to qualify.

2. Naturepedic Concerto Plush Pillow Top Organic Mattress: was: from $1,699 now $1,359.20 at Naturepedic with code JULY4
During our Naturepedic Concerto Plush Pillow Top Organic Mattress review our testing panel declared this bed as being a "dream mattress for side and back sleepers". Crafted using organic and eco-friendly materials, the Naturepedic Concerto is a breathable hybrid with supportive pressure relief and a luxurious feel. But with only one firmness, this softer bed won't suit stomach sleepers. Naturepedic doesn't run the evergreen sales we see from other sleep brands, so take advantage of this 4th of July sale. With 20% off all sizes of the Concerto, a queen is now $2,239.20, down from $2,799.

3. Beautyrest Black mattress: was from $1,549 now $1,249 at Beautyrest
The Beautyrest Black mattress is a customizable luxury option that features Triple-Stranded Pocketed Coil Technology to provide full-body support. But the real USP here is the range of firmness options and personalizations. There are up to ten feels to pick between and four support series, meaning whatever your sleep style, there's probably a Beautyrest Black mattress to match. Beautyrest sales are semi-frequent, but you can't always find a discount on the bed you want. If the Beautyrest Black has caught your eye, now is a good time to shop, with up to $600 off the mattress.

4. Essentia Stratami Organic Mattress: was from $2,915  now $2,186.25 at Essentia
The Essentia Stratami Organic Mattress is a natural latex mattress with a firmer feel and an impressive build quality. This luxurious finish stood out in our Essentia Stratami Organic Mattress review, and we were also pleased with the level of support provided by the organic materials. Unusually for a luxury bed, the Essentia Stratani is on the thinner side with a firmer build best suited for back and stomach sleepers. We're used to seeing this 25% off deal from Essentia appear around the major holidays, but it's still a good sale and one worth paying attention to if you're looking for an organic mattress. 25% off takes a queen size to $2,631.75 (from $3,509).

5. Sleep Number i8 Smart Bed: was from $3,399 now $2,379.30 at Sleep Number
Most of the beds in this guide offer a variety of firmness levels, but Sleep Number does things a little differently. One of the best smart beds and mattresses, the Sleep Number i8 smart bed has adjustable firmness. This adjustability is paired with integrated sleep trackers, for responsive firmness that changes to meet your needs. The i8 doesn't have the plush feel of other beds in this guide, but responsive firmness is undoubtedly a luxury, and particularly beneficial for combination sleepers with a habit of moving during the night. The i8 Smart Bed from Sleep Number goes on sale semi-regularly, but this 30% off sale only appears on special occasions. A queen is reduced from $3,999 to $2,699.30 for the 4th of July, which matches the impressive saving we saw for Memorial Day. 

6. Saatva Classic mattress: was from $1,395 now $1,195 at Saatva
We think the Saatva Classic is the best mattress in the world right now, a luxury mattress that really delivers on that premium price tag. Available in three firmness levels and two heights, the Saatva Classic suits almost every sleep type, with Lumbar Zone Technology soothing sleepers with back pain (and according to our Saatva Classic mattress review, it works). The current sale can't quite match the Memorial Day offer we saw at Saatva, but $300 off reduces the queen to $1,795 (was $2,095) and you can enjoy a full-year trial and lifetime warranty.

7. Purple Rejuvenate Mattress: was from $4,495 now $3,995 + free pillow at Purple
Combining ergonomic support with plush pressure relief, the Purple rejuvenate provides a premium sleep experience. In our Purple Rejuventate Mattress review our testing panel found the bed immediately comfortable, while the high level of support ensures a fresh feeling almost every morning. Purple is offering up to $800 off the mattress and a base, or up to $500 off the mattress alone. This reduces a queen to $4,995 (from $5,495) and with an added free pillow, this is one of the best deals we've seen from Purple.
