Have you ever been reclined in a recliner and had your head at an uncomfortable angle. If you put a pillow behind your head it raises it up too much, if you put your hand/arm behind your head it’s close to the right height but leaves you in and uncomfortable position.
Someone needs to make a recliner wedge. A piece of thick foam in the shape of a wedge that elevates you head to the point you want it. Make it customizable so it will fit any head, and attachable to the chair.
