These sheets are perfectly soft and fit my son's twin bed wonderfully. I live that they stay on the mattress no matter how much he moves around while he sleeps. My son is one of those kids who does acrobats while he sleeps and it had been hard finding sheets that can last his movement while he sleeps. The pockets on the fitted sheet hold nice and tight to the mattress and it makes life easier only having to put the fitted sheet on after washing it and not every morning once he is out the door for school. I love the softness of these sheets as well and have fallen asleep with him a few time while I lay with him at night to get him to sleep. The sheets also help keep us cool and we haven't broke a sweat while we have slept. I really do love this sheet set.
