Raising/elevating my tv?????
 

I need to raise my Mitsu 65907 about 6"-12" in order to accommodate the rear row of seating in my home theater. I was thinking of building a platform for it but remember seeing already made platforms at the stores where they display tvs.

Any suggestions on where to get something like this? Or even how to make it? I've seen them in acrylic, wood, etc.

Please help with any suggestions.
Thanks.
