We got a display model Sleep Number mattress from a guy that sells them out here. Only problem is no remote. Do you ever come across remotes or complete pump sets for these? I need to either buy a remote or an older version with the corded controls. I can crawl under there and get the model if you think you might find one.

So far we don't get anything in the Sleep Number line.
I would contact the manufacturer. When we have missing parts like that, we have had pretty good luck getting them from the manufacturers for a reasonable charge.
Also most remotes I've seen have to be synced to the unit. If it never worked, or stopped working when the batteries went dead, you might pull the battery cover off and see if there's a way to sync it.
Never mind about syncing it, I see you said you didn't have the remote.
I’d really rather have an old wired model. Up or down is fine with me. I don’t need to know the number.
I don't have any particular special access for parts on these types of items from the manufacturers, I just have to call in as an owner. I think it would be easier if you call them to try to get the original part unless that exact model came both ways.
