What can I use as a massage table around the house?

What can I use as a massage table around the house?
put a duna over the kitchen table, that should be stable enough and at the same time comfortable enough
I would love to give my girlfriend a massage (eventually), but I don't know what I could use that's narrow and long enough that she could lay on it completely. The only thing I could think of would be a twin bed mattress, but it's old and probably not massage-worthy. Any ideas?
