Years ago DM had a book rest that you put on your lap, or could use in bed with your knees up. It was hard on one side but then had a material side with beanbag beans in it that you rested on your legs. She's asked for one for Christmas this year. I've been googling but all I can find is either ones that are just wood with no soft side or if I put in bean bag, ones that are essentially small bean bags.
Does anyone have one of these or know what I mean or where I might find one?
