No air conditioning? 7 products I'd buy for a cool night's sleep in the 4th of July mattress sales
Trying to sleep during a summer heatwave is the worst, especially if you aren't blessed with air-conditioning. Well, I live in a building with no air conditioning — but I know ways to sleep cool in summer.
A lot of these methods are free and easy to implement, such as being strategic about when you open your windows and not eating close to bed, but it can help if you put together a cooling sleep setup.
Luckily, a lot of this year's best mattresses contain cooling materials and features, but there are plenty of other cooling sleep products to buy if you're not in the market for a new bed.
That's why I've put together seven of the best cooling sleep deals to shop in today's 4th of July mattress sales, from mattress toppers to protectors. And if you're hungry for more mattress deals, check out our top 11 mattress deals this 4th of July.
