Our PortaBaby sheet measures 27" x 38", and fits most play yard mattresses, including Pack-N-Play and Co-sleeper brands. Play yard sheets are notoriously hard to use and uncomfortable. Our PortaBaby® play yard sheet is different. It works like a pillow case, with the opening on the long side. Remove the mattress from the play yard, slip it into our soft, durable sheet, and secure the hook-and-loop closures for an easy fit. Drop the mattress back in and you're done! It won't come off the mattress like standard play yards sheets can.  On Sale in Sage Cotton
