I love my new Crisan 600 thread count sheets.  The deep 18 inch pockets fits my bed perfectly.  I purchased a new waterproof mattress cover fromWayfair and even with the added thickness my Cridsman sheets fit just beautifully.  The nect morning I didnt have to pull the corners back in,  the hertz were just as perfect as when I put on them.  I feel like I slept in a 5 star hotel.  Thank you Wafair for this beautiful set of sheets.
