Talk about the perfect marriage of old vs. new: iRock, a new chair being developed by the Swiss furniture retailer Micasa, charges your iPad or your iPhone as you rock. “Movement is energy and to collect as much of this energy as possible is one of our future challenges,” they explain. “iRock is a attempt to collect some of this energy and put it to real use. If you use iRock for 60 minutes you can recharge an iPad 3 to 35%.” The chair, which is handcrafted out of Swedish pine wood, includes an iPad dock and a set of built-in speakers in the back rest. Pretty nifty, but we’re not sure it’s worth forking over $1,300. Click through to get a better look at the rocker, and let us know what you think of the concept in the comments!
