No. I consider a 50″ the minimum size for a main viewing room TV. You can deconstruct the box to fit it under the bed. It should fit as long as you take it apart. The foam will be the hard part.
Congrats on the new TV. You’ll be very happy with the Panny. I know I am. With only a little bit of effort you can have it calibrated to meet the THX color spec of the G25. And, as a plus you can write about your calibration as well!
