The white panels at the bottom of the bed are just sheets of fabric and you attach them with Velcro strips which are also (supposed to be) included. Mine only came with one panel and one velcro strip so one side of my bed is missing it. And on top of that the adhesive for the velcro strips is not good quality because it constantly falls off and is no longer sticky. I’m trying to find some way to secure it. I would not recommend buying this bed.
