When it comes to sleep, I don’t mind spending on a first-rate mattress. However, I’m always excited to save if there’s an opportunity. Ahead of Fall Prime Day, shoppers can get a Casper Sleep Element king mattress for nearly 30% off. Considering the brand is famous for its top-notch sleep products, this is a sale you won’t want to miss.

The Casper Sleep Element king mattress has foam layers that effectively absorb movements. This means if your sleep partner is tossing and turning all night, you won’t wake up. It also provides both balanced support and medium firmness, which means it accommodates most types of sleepers. The open-cell Flex Foam keeps you cool all night, and thanks to its durability, it won’t sink or sag.

Your purchase also comes with a 100-night risk-free trial. That means if your experience is less than satisfactory, you can reach out to the Casper customer service team for a hassle-free return. Additionally, it comes with a 10-year limited warranty if it doesn’t hold up, and you can opt into financing your purchase if you’d prefer paying in increments.

This Casper King mattress has an average of 4.4 out of 5 stars and nearly 6,000 reviews. Most say it’s comfortable and high-quality, with good value. “Super comfortable mattress, especially for the price,” one shopper writes. “It is simple to set up and took me all of 10 minutes to remove the plastic wrapping. I would 100% buy it again, and I [recommend it] to anyone looking for the best quality for the money.”

So, if you’re in the market for a new mattress, now’s your chance to get a superior option for less. At 27% off, the mattress is available for just $619. Compared to the original price of $845, that’s a steal. Purchase some hotel-quality pillows to go with it, and you’ll have the ultimate sleep set-up!
