November is famous for Black Friday, but there are still a few days left in October.

Casper is currently offering 15% off sitewide with coupon code "DAYLIGHT". (Coupon will be applied automatically). After the discount, Casper Original Mattresses start at just $506 (they were $595). This is the best Black Friday sale Casper has had this year. In the previous year's holiday sale, only Casper's premium mattresses were 15% off.

Casper offers three lines of mattresses. They are the Original, Nova Hybrid, and Wave Hybrid. The Original is an all-foam mattress that gives a more contoured feel, while the Hybrid mattresses add lift and breathability thanks to specialized springs. (You can check out the Casper Mattress FAQ to find the best mattress for your needs and budget.)

For the best sleeping comfort, the Casper Original Mattress is the best choice. It is designed to help all types of sleepers with three zones of support for the shoulders, hips, and buttocks. It also has breathable foam to keep you cool all night long.

Meanwhile, if you're not looking for a new mattress, Casper also offers comforters, mattress toppers, and sheet sets at up to 60% off. This is the best price ever for Casper bedding, which is usually sold at 50% off.

This Casper mattress deal is valid through November 2. Make sure to follow our guide to the best mattress deals for sale all month long.
