While these are not "rocking" chairs, they ARE comfortable, well stuffed, shipped quick. They are just heavy enough to not be constantly thrown around by my pre-teens. I did work hard the first day to distribute the stuffing to the seat back portion of the chair. As a result of my efforts they were pretty much fully expanded the first night. They are smelly, though due to the foam. From what I can tell, they are indeed a memory foam mix. The fabric is microsuede and seems tough. Better than a bean bag!
