This is something i made after months of straining my neck while looking down at my laptop when sitting on the couch. It only really works if you sit like i do when on the couch, slumped back with feet resting on the coffee table.. But, it's also handy for use in bed. In both instances it helps reduce neck strain, keeps the screen at eye level and keyboard easy to see & use
