A lot depends on how tall your friend is. I am 5'9" so I really liked the longer fleece blankets they had. The width was fine, because we sat in recliners, but I needed the length to be longer than 72 inches, because I wanted it under my chin and under my feet. It also needs to be light and easy to move because you usually have to get up a couple of times to go to the bathroom. A bag to carry a snack/lunch is nice too. My chemos were 4 - 5 hours long.
