“Is this cabinet sturdy enough to add a wall mount for the tv to the back of the unit my tv is 50" on the diagonal, 44" wide. The cabinet is 44" wide. why can't the diagonal of the tv be greater than 46"? Is it a stability issue? the tv weighs about 60#. I plan to mount a wall mount to the cabinet and I assume the wood is sturdy enough to handle the mount. Does it sound like this will work with this cabinet? Thanks,”
