I have used it three (3) times. 1. I use it on my outdoor exercise mat for two of my 10 mobility exercises with my weights, two of which are on my back, raise my head up, raise the bar straight with both hands and count to 15, and to stretch mine Bend legs and pull my knees to stomach, repeat to 15. 2. I use this exercise for YouTube's Epley Maneuver for Vertigo, back of head tilted 20 degrees from top to bottom. Part for three different positions as shown on YouTube. 3. I can take it on a trip from home to make it easier to sleep in a motel with an upward tilt to prevent acid reflux.
