Juraj Talcik and Veronika Demovicova are two extremely good designers and visualizers from Slovakia. Some time ago they showed us what can be done with Marvelous Designer, in their short, but impresive video, called White bedroom.
Now they have prepared for us a series of free 3D models that can be downloaded from their webpage. These are real products from the brands Dedon and Poliform, which you can see below.
Outdoor furniture set by Dedon

All these free 3D models are highly detailed, and all materials and textures are included with them. They are prepared for rendering with V-Ray and 3dsMax 2011 or higher. This allows you to use them directly after download.
