So sorry to hear about your horrible experience with the bed. I had something similar when I was transferred to a rehab center that had only one kind of mattress. It didn’t feel like it was blown up at all, and I felt like I was lying on the metal infrastructure of the bed. I had just had a two level fusion in my lumbar spine, and I was really concerned it might end up doing some damage. When I couldn’t get any help, even a change in mattress, I signed myself out AMA because I had a new bed at home and lived around the corner from the facility. It was a horrible experience but at least it didn’t leave me with any sequelae.
