Serial Number begins with "L" and 12-16 digits long. Enter chair serial number, not the model number! Orders without s/n cannot be processed. You can usually find s/n on sticker located on frame or rear leg. Even if you call to order - we must have the s/n.
I received excellent customer service, correct and perfect products (transformer, power cord, and remote). The chair is up and running perfectly. I also received my products a head of schedule which I am so grateful for
