As a 3d artist I a have always enjoyed a good piece of 3d furniture.  I like the ones that are meticulously crafted with every detail.  I also hate it when they are not properly optmized to work with Vray.  DesignConnected.com fits the bill for everything I need.  They are priced decently, and they are SUPER high quality.  The best part is, they give away a bunch of their Vray models for free.  Check them out here.

Sometimes, though, I need a custom chair that they just don't have.  That is why I have been obsessing over how they create these awesome models.  I have been working on a workflow, and I should have a tutorial soon.  In the meantime, just go download all of theirs.  Trust me, it is really good stuff.
