This Pyramat Sound Seat video gaming rocker has dual 8W speakers and an exclusive ARX subwoofer (this should all mean something to your grandson) that will “rumble through” his body (yikes!). It’s the perfect seat for video gaming and is compatible with PS2, Xbox, GameCube, Nintendo DS and PSP. He can also plug in his iPod or MP3 player, TV, VCR or DVD player. For movies, it delivers multiplex vibes in unbelievable comfort. There’s a headphone jack, too, if noise bothers anyone. And it comes with all needed connectors. Ok, sounds awful to you, but this gift will immediately get your grandson to shout, “you rock!” — also known as an extremely enthusiastic, “thank you!”
