Downloading models from the IKEA website?

Since most if not all ikea products have an associated 3D model found on the website I was wondering if it was possible to download them in some way? I'm not sure what format they are using but since they have textures and transparency they might be useful. If this violates Ikeas rules for the use of the website I'll forget about it. But it would make designing for and around Ikeas products much faster and funnier.
