Looking for some advice on which way would be better to mount my flat screen inside my media niche. Niche is 5' wide, about 30" deep, built in cabinets and shelves at the top.
I have an articulating mount that wont extend far enough out from the back wall of the niche, so I am looking at putting in some soft of floating wall across the niche so I can attach the mount and then pull the TV forward to be flush with the opening, and also pull out further so I can get to the connections in the back of the TV and also get underneath for access to the back wall. There will also be a movable cabinet underneath the TV that I will move out when needed. I cant put the TV directly on the cabinet because it will sit too far back in the niche.
My main concern is that maybe the 2x10 in the 2nd option will flex or twist with a 5' span. TV weight is approx 60lb, mount is 32lbs.
Here are the 2 options that I think I have...
Frame a small wall with 2x4's about 10-12" high attached to the studs on either side, with vertical studs in the middle to attach the mount using lag bolts.
Using 2x10 attached on either side, with a 2x10" spanning the width, attached to the sides with steel angles. Then bolts through the 2x10 to attach the mount.
Thanks in advance.
