Have given this chair for Christmas my son. He is 13 and total begeister. The sound is absolutely great for PSP games (as if you were right in the middle) and listening to music on laptop, and it is even seen only in that chair watching TV (but not connected), because he finds it so convenient. For me he is a little too small, because the knee is always hanging in the air, but still pleasing to the swings and short-wave slopes. One must not swing to flourish only because you then tilts slightly backwards, because there is no "braking device". Another disadvantage is the cable to the device (which is why the TV is not connected) and the wall outlet. But would even buy it in any case a second time !!
