I have just purchased one of these at Currys for £97.86. They have it on special offer and the cheapest I have found it online is £120 or there abouts up to £150. The PM 420W is pyramat's new model in the sound rocker range. Wireless enabled it will fit the average sized person providing comfortable support to the body and head. Giving an experience like no other to videos, games and music. The wireless provides 8 channels, and up to 8 gaming seats can be connected together. The PM 420 is compatible with most media devices, iPod etc. For storage the Pyramat can be folded.
