LOVE THESE SHEETS! If you need a sheet with deep pockets then stop looking and order these. Finally a set of sheets that stay in place and do not come off of the mattress. These sheets are super soft and exactly as described. I have a 16 inch mattress with a 4 inch topper and still have enough room so that sheets are not stretched tight. I ordered white for 2 cal king and will also be ordering additional ones. My sheets came in a package that says Bare 1800 ultra microfiber.
