We had a king room with pull out sofa at GF and asked for bed rails. They are very large. We requested ahead of time, and then went to front desk to check in and requested them in person. They were brought up within an hour. We used them on the pull-out, and used the little tube pillows too, not sure what Poly has for bed and pillow options. Our kids were secure and had no problems sleeping at night or taking a nap.
