You won’t lose any sleep over these newly lowered prices on select Casper bedding. The brand may be most well-known for boxed mattresses, but right now, its beloved Cool Supima and Weightless Cotton bedding is half off on top of the brand’s End-of-Season Clearance Sale.

The Weightless Cotton line is ultra light and incredibly breathable, with feathery softness to provide maximum comfort, while the Cool Supima collection has a crisp feel that’s ideal for hot sleepers. For each, choose between a pillowcase set, sheet set, duvet cover — or both — in sizes ranging from twin to California king and a variety of colors. Prices start at $25 for a standard pillowcase set to $140 for a combination sheet set and duvet cover.

On top of this deal, Casper is running it’s End-of-Year Clearance Sale, which means you can take up to 20% off all orders that include the purchase of a mattress through March 23. Choose from any of the three models offered by the original mattress-in-a-box purveyor: The original Casper mattress, the brand’s most popular mattress, is 15% off and starts at $506; the lower cost Essential mattress is 10% off and starts at $356; and the Wave mattress, which uses gel pods and foam to target spinal alignment and keep you from feeling overheated at night, starts at $1,116 with the most significant 20% off discount.

Casper offers a 100-night risk free trial, free shipping and returns, and a one year limited warranty. Certain sheet sizes and colors are already sold out, so shop soon to get the bedding and mattress of your dreams at a discount. For more great deals, check out CNN Coupons.
