Hospital bed for testing. We are attempting to borrow one from Altman Clinical Research until the end of the project, still waiting to hear back. Have called bed manufactures, one has offered a rental. If these don't work sponsor wants to buy a used bed for this and future projects.
UPDATE TUESDAY NIGHT: Heja got in contact with a bed rental company in OC who will lend us a bed. Waiting to hear back from a company in SD, may have similar offer with easier logistics.
