Musical chairs: Pyramat Sound Rocker and LumiSource Boom Chair 3.0

If your chair just isn't loud enough, one of these two seats might be for you. The Pyramat PM220 Sound Rocker and LumiSource's Boom Chair 3.0 are two gaming chairs with built-in speakers for precision rocking. The PM220 Sound Rocker has a 5.5-inch subwoofer inside, while the Boom Chair 3.0 has a 4-inch subwoofer and two pairs of vibrating motors to let gamers feel every shot, punch, and explosion. Unfortunately, neither chair has legs; they're just seats that you put on the floor and sit on. Both chairs ship in early January. The Sound Rocker costs $99, while the Boom Chair 3.0 costs between $99 and $130, depending on the materials and other options.
