When Is the Best Time to Get a Sleep Number Deal?

The best time to get the biggest reductions on anything from Sleep Number will inevitably be Black Friday (the last Friday in November) and Cyber Monday (the first Monday in December), this year.

If you'd prefer to wait until 2027, you can expect to see reductions in the post-Christmas sales in January, Federal Holidays, such as the 4th of July, and Labor Day in September.

Shopping at these times, as well as during seasonal flash sales that happen for limited times only, will ensure you never have to pay full price, so they're definitely worth taking note of and waiting for.

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, which is a brand name for a patented combination of natural volcanic minerals, and 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.

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 six different sizes and temperature-controlling materials, whether you run hot, cold, or somewhere in between. 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.
