QUESTION: I am trying to figure out the model I have. The controller says SP2-B. I am looking to buy another chair so I would like to know which of the other models is the same as mine. Thank you. ANSWER: Sorry the controller number does not help determine the model of the chair. Since the controller has been upgraded and modified in the past. You need to know which model of lift chair you currently have. The chair should come with labels showing such information.
