A:AnswerMy middle shelf broke before I could ever put anything on it, I'd advise heavier loads on top or on the bottom, use the middle for decoration. No more than 10-15lbs.
A:Answer33 1/4”. It seems like a very good height for viewing. The mount also swivels but I would turn it from the mount rather than the tv since the tv screen is so,thin.
A:AnswerYes absolutly. I just mounted a 65" TCL to it no problem. There is a solid 6-8" between the bottom of the screen and the top deck (im not in front of it or I would measure for a more accurate description) the height is perfect for normal livingroom seating.
A:AnswerThe number provided on the packaging is a direct manufacturer's number. Easier to replace one or all sheets of glass than to return the whole set.
A:AnswerI don’t have a curved TV but mounted a new LG CX 55” fairly easy. Included Whalen instructions include parts and diagrams for both “flat backed” and “curved/recessed back” TV’s
Hope this helps
A:AnswerA center fits easy if you're using the rear-mount option rather than setting the TV on the stand. I have a Polk Audio CS2 (which is a rather large center channel) and it doesn't come close to obstructing the screen at all with a 65" TV.
