Right now, the best thing you can buy at Costco is better sleep! This superstore has exclusive Casper mattresses in stores and online that offer memory foam cushioning and better edge support. You can choose from full to California king sizes for any room in your home. And typically, Casper mattresses would cost $800 or more on their website, but Costco has them for as little as $549.

What customers are saying

Casper mattresses have made a name for themselves in recent years thanks to their plush comfort and support. And customers online are raving about this deal.

One commenter on Reddit said, “I'm laying on mine now, love it. Massive upgrade compared to our old very sunken mattress.”

Another Redditor adds about the price, “The actual bed I wanted was over $2000. I got a nice mattress [Casper] for 1/4 of the price.”

Why you should buy your mattress at Costco

Certain locations are offering special deals on Casper mattresses for a limited time. On Reddit, someone in New Jersey even found it on sale for $399.97, which is a few hundred dollars off its typical retail price.

What makes these Costco-exclusive mattresses different is that they come with a washable cover, so you can enjoy them for years to come. If you’re in the market for a new mattress, it may be worth stopping by your local Costco to see if they’re having a special sale on this must-buy.

Bottom line

This might just be the best purchase you make all year.
