They snatched some details by the wheelchair's designer:
Quote:
We've received an exclusive scoop from the chair's designer, Ken Borochov, that he was commissioned specifically by Lady Gaga herself to design the wheelchair. Ken is the creative force behind MORDEKAI, and has designed pieces for Mama Monster in the past, but nonetheless, he was still surprised to get the call. "I certainly wasn't expecting that phone call and have never done a wheelchair but am always up for a challenge and was thrilled to create what I affectionately dubbed the Chariot, a chair fit only for a queen," Ken said in an official statement. Get all the deets on the Chariot, and Gaga's accompanying look, after the jump!
Logically, Ken looked first to a throne for his inspiration. He then fashioned the Chariot from tufted calf leather, inspired by classic motorcycle jackets, adding a removable leather canopy that we REALLY want to get a look at. The wheels and hardware are 24-Karat gold plated. Maybe the craziest detail of all of this, the whole business had to be completed in a single week! Well done, Ken Borochov, well done.
