At least for me oldish mattresses would be quite easily available.
My guess is that anything to absorb frequencies is probably better than nothing. However, A matress isn't designed for absorbing frequencies so I'd bet that the absorption will be uneven, with some frequencies passing through like nothing is there.
Owens Corning 703 is tested and designed to be effective at reducing audio frequencies. If you hold it near your face and talk into it, you will be amazed at how it is like a vacuum sucking up sound. It is GREAT stuff, and really not that expensive.

I'm a bit opposed to drilling lots of holes into the concrete walls and ceiling.
Are there alternatives?
703 is light enough that you can wrap some material around it and hang it with adhesive pieces of velcro. Then if you need to isolate a vocalist for a voiceover recording, you can grab a couple pieces off the wall and make a mini isolation chamber.
