Happy Sleep Week, readers!
Not positive what Sleep Week is? Here’s the TLDR; back in 1998, the National Sleep Foundation founded Sleep Awareness Week to educate the public about sleep health and hygiene, timed to kick off with Spring Forward (which is now, if you haven’t already reset your clocks).
Since then, we’ve shortened it to Sleep Week, and it’s mostly a great time to find huge savings on mattresses. There’s no better way to celebrate the original intention of Sleep Week than by, well, sleeping. In fact, it’s sort of the whole point.
- Up to $600 off Saatva mattresses
- Save up to 50% on mattresses with up to $599 of accessories included!
- Take 50% off Lull mattresses
- Save $500 on any Amerisleep mattress plus get free shipping
- Save up to 60% off mattresses and more at Wayfair’s 72-Hour Clearout Sale
- Editor’s Pick: 15% off the sleek NANU Arc analog-style alarm clock
To do that, you’ll need a quality mattress. Don’t have one? You will — if you visit the Sleep Week mattress sales at Casper, Amazon, Avocado, and other retailers all week long.
If you want to ensure you’re celebrating in the biggest way possible, we suggest taking a look at our guides to shopping for mattresses online, where we share a few expert-approved tips of the trade.
And now, onto the sales!
