I purchased flannel sheets in the BELLE COLLECTION. I got the blue snowflake material. They are very soft warm and cozy, BUT they are only good for less than a 14 inch mattress. I have a 15 in mattress and they DO NOT fit my mattress, after I washed them in cold water, air dryer.
I did send a note to customer service and they responded very quickly by sending out a new set of sheets. I didn’t even wash the new ones I wanted to see if the fit and they did not! Same as the first set. So just make sure you have less than a 14 inch mattress and they should fit just fine!
