It's so hard to find sheets for our split-California King bed, since the stores don't seem to sell sheets separately anymore. I was thrilled to find these sets on Wayfair. I had the last sets I bought custom made. I put them on yesterday and was surprised how much material there was. The fitted sheets are oversized for deep mattresses so I had extra material to tuck underneath. They didn't get loose and bunch up overnight. The top sheet hung almost to the floor on both sides of the bed. The quality is very good. The sheets are very soft. I'm happy with my purchase.
