We’re thinking of getting DD a bigger bed. She currently has a single. Her room is really a bit too small for a double bed (there would be no space for a bedside table as there would Only be 15cm between the bed and the the doorway. So we’re considering a small double instead. However all bedding seems to only come in single/double/king/super king sizes. It’s not really a problem for duvet covers (we’ll probably just get her a double duvet). But how do sheets work? She is expected to change her own bed, and has only ever used fitted sheets. Do fitted sheets for small double beds actually exist?
