Thanks Force, mine falls from that position when I have the foam pad on the mattress.
Bikendan, it does have the snaps on the bed platform and the mattress but the snaps do not stay attached with the added thickness of our Costco Gel Memory Foam topper. It bulges out like Force's mattress and inevitably ends up on the ground or up against the slide. The slide catches it on the way out. Not a huge issue but enough to irritate me. I was just curious how others addressed this.
