Just might be easier to get a holder for your ereader and add a Kobo remote since they're back in stock. One friend of mine uses a holder that stands on the floor and the remote to turn pages since they have issues with holding the ereader for a long time. I don't think the URL is for the one they own but looks similar. Their spouse moves it around the house as needed.
