Frequently asked questions
Does Purple sell flat sheets separately?
Yes, Purple sells flat sheets individually for many of their sheet collections, including SoftStretch, Plush, Harmony, and Organic Cotton. You can purchase them directly from Purple's website or select retailers.
What size flat sheet should I buy for a Purple mattress?
Purple flat sheets are sized to fit standard mattress depths and also deep-pocket versions (up to 18 inches). Measure your mattress thickness and choose the corresponding deep or regular size. If you have a Purple mattress with a topper, go with deep pocket.
Are Purple flat sheets OEKO-TEX certified?
Many Purple sheet sets, including Harmony, Plush, and Stretch, are OEKO-TEX certified. The Organic Cotton sheets are GOTS certified. However, always check the product label before purchasing.
How do Purple flat sheets compare to cotton sheets?

Can I use a Purple flat sheet on a non-Purple mattress?
Yes, Purple flat sheets are compatible with any mattress, provided you choose the correct size and depth. They are not exclusive to Purple mattresses, just designed to pair well with their grid technology.
