The bed just shifted

I have had the bed for like 4-5 years now and up until now I have not had any complaints. I had the bed moved due getting floors done in my house and so the bed was up against the wall for maybe an hour or two and now the bed is completely uncomfortable and all of the cushion is in the middle of the bed. The bed is completely lumpy and uneven. I don't understand how by placing the bed upright would cause it to shift. I am completely upset by this and now I am stuck with an uncomfortable bed until im able to buy a new one. I cant seem to find anything about the manufacture online or the company itself.
