Three position lift chairs allow you to sit in three positions after getting into the chair. The first position is sitting upright like you would in any non-reclining chair. The second position is sitting back at about 45 degrees where you can watch TV or read. The third position is sitting at almost a full recline. From this position you can fully relax or sleep. Of course, like other lift chairs, three position lift chairs have a mechanism to assist you in getting into and out of the chair.
