100 Polyurethane from Walmart ?

These are mattress pads from Walmart full size for $14.95 100% Polyurethane. Are these same as acoustic foams on the market for sound absorbers ?

Etran, you're better off with high density fiberglass as sound absorber than most foam products. Both Owens Corning and John Mansfield make these panels in 4X8 feet and 1' to 6" thick.

This high density fiberglass is what my room is covered in and what most recording studio's use.

The down side is the cost of the rail system that allows for fine finish of acoustic cloth to cover it all up.
