What is a Fitted Sheet?
A fitted sheet is a type of bedsheet designed with elasticated corners that grip the mattress. Unlike flat sheets, it stays securely in place, covering the top and sides of the mattress.
Key Characteristics:
- Elastic edges ensure a snug fit.
- Protects the mattress and adds a layer of softness.
- Used as a base layer beneath the comforter or duvet.
