Castors of the like never seen before, thoroughly innovative in shape and in the construction method as well, aiming at creating the kind of simplicity which is the hallmark of all great inventions. ROTOLA COLLECTION is the highest synthesis of the “wheel” system: a hole and void. We have challenged Ogtm in a way that only few manufacturers would have been so courageous to take up, questioning the wheel system itself and its evolution. We have made a revolutionary castor which almost seems to fly in the face of the rotatory mo- tion, but which is however so plain that it seems to have been on the earth all the time. The real evolution of ROTOLA COLLECTION lies in the way it is manufactured: few parts all assembled together through a short sequence of manual operations with no use of screws nor rivets. A sheer industrial product.
