Unfortunately we have graduated to a hoyer-type lift but prior to that we used transfer boards with my wife quite extensively. We have each of the three types, Beasy, wood with slots, and plastic w/o slots. My wife needed my assistance to slide transfer and the Beasy was the easiest and safest for most transfers. Once underneath you, just the disc slides across. No matter what board it is not always easy to get it sufficiently underneath you for a safe transfer. It is a lot easier to remove though. For boards other than the beasy, you want one that you will slide easily on and preferably one with one or two holes/slots to hold on to keep the board stable and safe (if you don't slide well on the board or don't get on it well enough, you and the board will want to slide rather than just you). A long board can also be handy in certain situations where you can't get real close and you want to make sure you have enough board at each end to be safe. We had a generic carrying bag attached to the back of my wife's power chair and a transfer board easily stored between the bag and the back of the chair resting on the base. Good luck.
