The RePoser is my invention, and RePoser, Inc. is my company. The RePoser is a portable armrest designed to improve posture and provide greater comfort to a passenger seated in an economy airplane seat. Constructed of lightweight aluminum, with a custom pillow and carrying pouch, the RePoser fits easily into your carry-on bag or purse, or it can be hung over the handle of a roller bag. It expands into an elevated armrest that sits on the side armrests and provides an elevated armrest in front of the traveler, that supports the weight of the arms and helps maintain a balanced, gravity-neutral posture.
