First, you need to decide between a traditional rocker and a glider. Traditional indoor rockers are the kind that rock on two long curved pieces while gliders are mechanical pieces of furniture that mimic the feeling of a rocking chair by gliding along rungs. There are pros and cons to both approaches. With a traditional rocking chair, there is no risk of mechanical creaking or grinding noises, but there is a risk of catching a toe, foot, hand, or tail under one of the rockers if you are not careful. With the glider, the rise can be more smooth, but the mechanical parts need to be covered up and the decorating options are not as great because there is upholstery on the chair. A traditional rocker is plain and you can dress it up as much or as little as you want.
Indoor chairs can afford much nicer cushions with all manner of liner fabrics, like suede, cotton and more. Unlike the cushions of the outdoor reclining Adirondack chair, which consists of waterproof polyfill, indoor chairs can be stuffed with everything from cushy cotton to luxurious memory foam.
