There are a range of mounts out there, just make sure the size\weight rating are sturdy enough for your TV. The tilting mounts are very sturdy, I have my 46" TV in the living room on one and it was a cheapie mount. Been up there for over a year with no issues. When you say swivel are you talking about a swing out arm?
Personally, I dont have a TV in the bedroom. That room is there for 2 reasons, sleeping and sexy time!
