The first one I found was at Crate and Barrel, which they call the Loop Media Center (pictured) for $600:
“Install your flat screen TV on our clever plasma panel rather than drilling into your walls. Four recessed cubbies along each side hide up to 48 DVDs.”
Target has a similar Platinum Entertainment Center model for a hundred less than the Loop in a blonde veneer.
And, for $1,200 (ouch!), Pottery Barn has the Caleb Flat-Panel TV Stand.
If you’re interested in mounting your flat screen television without the use of a wall or a television stand, then hopefully these options will get your search headed in the right direction.
