Really does fit oversized mattress and top sheet is also longer/wider so there is a nice top to fold over top of blanket as well as tuck under at the bottom.
Great "hand" as well; hard satin finish, very comfortable to sleep on and washed well. Planned on ironing cases and some of top sheet and that made a nice 'feel' as well.  This was a great bargain and arrived about 30 hours after ordering!
