Frequently Asked

Technically speaking, thread count refers to the number of threads per one square inch of your sheets. When we started designing our bed 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 or softness. 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 bed sheet set! Any mattress up to 14 inches high will work.

All of our bed sheet sets are machine washable. We recommend washing your bed sheets in cold water on a gentle 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 bed sheets looking good as new, use a non-chlorine, oxygen bleach with each wash and wash them every one to two weeks.

Most sheets are labeled to match the corresponding mattress size. However, there are some instances where a different size bed sheet can be a good fit for a mattress. For example, a King flat sheet works perfectly fine on a California King mattress.
