According to Innovations Report (which has a picture of the Dressman), one of the advantages of this product over a conventional iron is that while the frame of an iron can get very hot and can damage the garment, the temperature of the dummy never gets to that high of a temperature, and thus will never damage the garment. As well, while the base of a conventional iron crushes the cloth, causing it to lose its pristine look after a few ironings, the Dressman just uses air so the cloth is left undamaged for longer periods. More pictures of the device can be found here.
So when can we get it? For now, it’s only available in German, unfortunately. It will be available in the UK before the end of the year. No word yet on when it hits North America.
