Memorial Day is coming early to Sleep Number – beat the crowds and save big on smart beds and bedding
Keep cool and shop smart with deep discounts on Sleep Number smart beds and thermoregulating bedding


Memorial Day is fast approaching, and Sleep Number are getting a head start on the celebrations with a site-wide sale. I've found the best deals on their smart beds and thermoregulating bedding, just in time for summer.
As the resident Sleep Editor at Homes & Gardens, I lead a team of expert testers in the search to find the best mattresses and bedding. Together, we've tested sheets, pillows, comforters, and mattresses from more than 50 brands, and we agree that Sleep Number makes some of the best cooling sheets for hot sleepers and summer nights.
I spend my days shopping the mattress sales, so I can spot the difference between a good deal and a low price on a poor product. Here are a few of my favorites from the Sleep Number Memorial Day sales to help you get your money's worth. Later, I'll answer all your Sleep Number FAQs.

Sleep Number makes some of the best pillows in various shapes to suit every sleep position: the Contour has a dip to cushion your neck and shoulders, while the Ultimate is filled with inserts that you can remove and replace until you reach your ideal pillow height and firmness.
These sheets are really coming into their own as the weather warms up. Made from cotton sateen, this sheet set feels silky and smooth against your skin. The fitted sheet features a SmartFit design: that's just marketing speak for all-around elastic to grip the corners of your mattress. I haven't had any trouble with my sheets slipping since I started testing.
This mattress layer is a cross between a topper and a protector. Filled with plush fiberfill and wrapped in a poly-blend cover, the mattress layer is fitted with stretchy corner straps to hug the sides of your bed. I'd put it up there with the best cooling mattress toppers and pads for hot sleepers.
As a hot sleeper, I often overheat in the summer, but I still like to sleep with a layer. On seriously hot nights, I switch out my best cooling comforter for a lightweight blanket. This one is filled with breathable lyocell and threaded with antimicrobial zinc to bust bacteria.
Sleep Number makes the best duvet inserts for customers who share a bed, but not a sleep style. With their Create Your Perfect Comforter program, you can choose your warmth (Light, Medium, or Extra Warm) and customize your fill (Down or Down Alternative) on either side.
FAQs
How does Sleep Number bedding work?
Sleep Number's True Temp collection incorporates something called 37.5 Technology: that's a brand name for a patented combination of natural volcanic minerals, which is supposed to regulate temperature and relieve humidity.
The micropores on the minerals are able to capture infrared radiation, which is a kind of thermal energy our bodies emit. 37.5 Technology helps to absorb excess thermal energy and speed up the evaporation of moisture, keeping you just the right side of cool and dry.
Is Sleep Number bedding worth it?
I think so. I'd say that Sleep Number is one of the best places to buy bedding for hot sleepers. If you suffer from hot flashes or night sweats, or you live in a warm climate all year round, then you need more than breathability: you need active cooling and thermoregulatory technology.
So far, my team of expert testers and I are impressed by the practical benefits of Sleep Number bedding. Testing through heat waves and summer nights, we've found that Sleep Number sheets and pillows, in particular, do a great job at wicking away moisture and dissipating heat. The prices are competitive, and notably less expensive than you'd expect to spend on luxury linen or cooling silk.
