Bunk bed comforters are designed to exactly match your mattress’ measurements and take away some of the challenges of making your bed every morning. The two bottom corners of this special comforter are tailored to fit the bottom corners of your mattress.
This helps the comforter stay on the bed, with no tucking necessary. As for sheets, as long as your mattress has standard dimensions, most sheets designed for your mattress size should fit just fine.
