Daniel (target) delivered the stand today. With the help of a dolly, the two of us got it inside the house relatively easily. My worries were unfounded.
The stand looks absolutely amazing, great handiwork and feels extremely sturdy.
The doors have yet to be installed yet due to time constraints but that works out well since tomorrow is the big setup day and I don't need any doors getting in the way at the moment.
And here's the "living" room.
