This sheet set makes your bed an inviting spot to stretch out and relax after a long day. It includes one fitted sheet, one flat sheet, and two pillowcases (one for the twin size). Each item is crafted from 100% organic cotton with a breathable percale weave that has a 300 thread count. We love that these sheets have deep pockets, and fit comfortably over mattress toppers and thicker mattresses up to 18''. Not only are these sheets organic, but they’re also certified as environmentally friendly. When it needs a refresh, simply toss this set into the washing machine.
