These high quality, breathable flat sheets are the same fabric composition as your CDFC duvet cover and pillowcases. The cotton fabric is 300 thread count, single-ply, percale weave, which makes for a light, breathable material that can stand up to many washes. The cotton is combed, mercerized and is 30% long-staple, all of which help with the softness, smooth handfeel, and durability. The top and bottom of this flat sheet are identical. This means that you can rotate it 180-degrees, while maintaining the same look, prolonging the wear and tear that can occur from always using the sheet in the same direction. This flat sheet can accommodate up to 16" mattress height. (Be sure to include the height of your mattress topper in the 16" total if you have one!) Last, but not least, this product is packaged sustainably with recyclable, biodegradable, and water-soluble materials.
