It is probably worth pointing out that mattress foam is very different from proper acoustic foam. Mattress foam my have an effect at high frequencies but it will do nothing to tame the mid and low frequencies which are often a bigger problem with home recording rooms.

Acoustic foam will work on a wider frequency range but, if you are on a budget, you would probably be better off looking at rigid fibreglass like Owens Corning 703 (in the USA) or Rockwool RW45 or RW6 (in Europe) covered with fabric.
