Can I use any type of mattress on a tempurpedic adjustable frame?

A local furniture store closed and donated their leftovers to our local thrift store. I picked up two tempurpedic adjustable beds but without the mattresses. I can’t afford their mattresses so I’m wondering what kind of mattress I can use on it. Thanks!
I’m getting mixed answers from different places online and locally. What kind of mattress do you use on your adjustable bed? Thanks.
