Art & Barbara,
Welcome to the Forum. We have a 2910T (& love it!). In answer to your question, when the BR slide retracts, the bed slides under the desk area on the opposite wall. It is "accessible," but not in the sense of being able to walk around the foot of the bed.
Hope this helps. Feel free to ask us any other questions you might have regarding the 2910T.
