DIY acoustic panels?

I tried 6" foam rubber suspended from the ceiling with some effect, with 4" foam on part of the side and back walls.

When I bought my new house, I made a deal with my wife, I got to do the family/dining room and kitchen and she got to do the rest of the house.  To that end, I have bolted 2 king size mattresses to the back wall, and a queen sized mattress to each side wall.  I then suspended the same foam from the ceiling.  Amazingly clean sound source, but I am running a 500w output amp, with 440,000 microfarads of power storage into a pair of modified Whisper Legacies, full Valhalla/Odin loom for the mids and treble and LAT 12 guage speaker wire for the bass.  I can turn it up to about 30% before I have to leave the room.  Amazing sound.  Cheap new mattresses are the way to go.

Can you sleep vertically on the mattresses? And do you think mattresses are way over-priced?

I got a fair amount of foam acoustic panels made up here. Price was good, but I think that also reflected in the quantity I was after.
