I bought this because I thought it would go perfectly with my 2-year-old son's "rocket ship" room. The sheets are way too big for his standard twin size mattress, nor are they very fitted. The fabric is hot and doesn't breathe. When I washed the sheets with other like-colored clothes, the dyes bled out - and now a whole load of laundry (including my favorite jacket!) is completely ruined. I plan on returning this hunk of junk.
