The sheets are flannel, one purple and one yellow. They are 5 dollars each for fitted sheet only or 8 dollars for fitted sheet/top sheet pair (in the same color).

The vinyl mattress covers are hypoallergenic and waterproof. The upper side has a fuzzy fabric so that your sheets do not slip or grip annoyingly. The photo shows both sides. There are two mattress covers, so they are 10 each or 15 for both.
