I was looking for deep pocket sheets for my california king pillow top mattress. These sheets were a great price so I ordered them. The deep pockets are great and fit our mattress nicely - not tight. They are a very nice weight - very warm. We usually use an electric blanket in the winter and with these sheets there have very few nights where we've needed to turn on the blanket. My only complaint is that the flat sheet is very short and I am unable to tuck the end under the mattress at the foot of the bed. The fitted sheet fits nicely and is plenty big enough but the flat sheet is a little small. Overall, I would recommend these sheets. Excellent quality (so far) and a great price.
