For a more affordable smart mattress (still with a good discount) we reccomend Sleep Number's Classic Series. The comfortably breathable design has a cooling, ceramic gel layer to help with the heat and contour to your body, allowing you to feel fully supported no matter your sleeping position.
Summer nights are not always comfortable for hot sleepers like me, but I still like to sleep with a layer. I like to switch out my best cooling comforter for a lightweight blanket like this one, which is breathable, antimicrobial, and hypoallergenic.
Sleep Number makes some of the best pillows, from the Contour with a dip to cushion your neck and shoulders, to the Ultimate, which is filled with inserts that allow you to adapt it to your perfect height and support level. They're on Buy One Get 50% off right now.
FAQs
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.
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.
Design expertise in your inbox – from inspiring decorating ideas and beautiful celebrity homes to practical gardening advice and shopping round-ups.
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.
Which Sleep Number bed is best?
The best Sleep Number bed is entirely down to your personal sleep style. All of their beds benefit from adjustable firmness (soft, medium or firm) on both sides, depending on whether you sleep alone or with a partner. The mattresses come in 6 different sizes, and temperature controlling materials, whether you run hot, cold, or somewhere inbetween. And the bases are adjustable, too, to ensure maximum comfort for sleep, reading or watching TV in bed. If you're not sure which to go for, there's a helpful quiz on the Sleep Number website to help you figure out the best one for you.
If you're particularly shopping for cooling bedding, take a look at the best Amazon cooling sheets and get yourself some Amazon Prime Day deals while you're at it. While our round-up of the best cooling mattress toppers and pads will help you narrow down your search.
