How does thread count work?
Technically speaking, thread count = the number of threads vertical + horizontal 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. Our sheets are deigned to give you that fresh-pressed dress shirt, cool feeling.

Will OkiOki sheets only fit on a OkiOki mattress?

You definitely don’t need a OkiOki mattress to use OkiOki’s Sleepy sheet set! Any mattress up to 14 inches high will work.

How do I care for my sheets?
All of our sheet sets are machine washable. We recommend washing your 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 sheets looking good as new, use a non-chlorine, oxygen bleach with each wash and wash them every one to two weeks.
