These sheets are very soft and fit my queen size bed perfectly. The first thing I noticed was how thick the elastic is.  They stay on my mattress regardless of me moving around when i sleep.  I love how the fitted sheet holds tight to the mattress. I also love how soft these sheets are, unlike other 400tc I have used. The sheets also feel cool and prevent me from sweatng. I especially like the sheen on the material. I would recommend these sheets to anybody looking for a comfortable night's sleep
