So comfy!
I love these sheets! They are light flannel, not the kind my grandma used to have! Great for our "chilly" SoCal weather.

Frequently asked questions
Technically speaking, thread count means the number of threads in one square inch of your sheets. When we started designing our sheets, we realized that while we’re taught to look at thread count, we weren’t really sure why. Through research, it became clear that higher thread count doesn’t always mean higher quality. In fact, more threads can actually make sheets heavier and less breathable.
You definitely don’t need a Casper mattress to use Casper’s one perfect sheet set! Any mattress up to 14 inches high will work.
All of our sheet sets are machine washable. We recommend washing your Sateen sheets in warm water on a normal cycle. Tumble dry low, and remove from the dryer as soon as possible to keep them from wrinkling. Warm iron as needed.
To keep your sheets looking good as new, use a non-chlorine, oxygen bleach when needed and wash dark colors separately.
