Sew a triangle wedge pillow to lean against when reading in bed. The triangle shape is also good for elevating the head while sleeping, to help keep with respiratory issues. The angle of the wedge allows you to create either a tall triangle (for leaning against) or a short triangle (to elevate the head) from one pillow. You can sew one yourself using an easy sewing tutorial from Hello Sewing.
