(Dead Link Removed) (Dead Link Removed) and when I put my head down in the middle I was amazed. All the noise and electrical hum that was issuing from refrigerators, ac's and my theory that the breaker even makes noise, went away almost completely. I couldn't believe it, so I tested it out with my rode K2... all those wasted dollars on cubicle walls and 1" thick eggcrate studio foam!!! WHY?!?!?! I just wish I knew where he got this one so I can go get a few more. Long story short, if you ever find a nice little mattress that uses an eggcrate on the top (which by the way is not really visible because theres a zippered sheet around the mattress, not sure if that helps or hurts the sound, but I like it just fine with it so I'm not gonna take it off)... GET IT! I lego'd up some pvc pipe to keep it bowed and also elevate it when I need it.
