Aye, that I can.

I googled "bed dimensions," and...well, for full size beds, I found two numbers:

53" x 80", and 54" x 80"...I had no idea which to choose, so what you're seeing above is 53.5" x 80".

Still a bit too "thin" height-wise, but I will most certainly change that. Also, I am looking into Maya 8.0 nCloth simulations, so I'll get some bedding to drape over the mattresses (yes, I'll be adding another).
