OMGosh! I can't rave enough about these sheets!! We have a super thick mattress and a foam pad on top of that, we can never find sheets that have deep enough pockets...can I say, WOW!!!!? These sheets are awesome, they fit the corners with room to spare and seem extra long because they tuck in at the bottom of the mattress as well.....my bed looks so nice, and the corners stay on the mattress...I ordered another set!!
