As stated before, an 85-inch TV is actually larger than a twin-size mattress (at least in length and height), so you’re going to have a heck of a time getting your arms around it to lift it. A single person can likely get it up off the ground, but the sheer size of it will make it very awkward to maneuver if you’re trying to transport it or hang it on a wall. Best to see if a friend can give you a hand rather than risk a big, expensive TV.
