Dorkenwald-Spitzer take the idea of dream interiors one step further with their wall furniture, which are basically strips pre-printed with furniture and accessories that are suitable for hanging on the wall and therefore instantly enhancing your space. They are reusable, waterproof and washable so even if you move house, your furniture can come with you.
The idea and imagery won't be to everyone's taste but, if you do want to invest, many of the images have a retro feel. Sacco shown here is presumably named for the beanbag lurking around the corner and the second image, LC2, is named after the armchair shown in the right of the image. Both designs come in four strips, measuring 186cm x 220cm and costing 210 euros. So not cheap, but cheaper than investing in the furniture (and cat) that they illustrate!
