Ordering slings for this double can be a little tricky. Prior to 93-94, this glider used a sling with a tension rod pocket sewn into the back of the sling. This pocket accomodated a tension rod which was connected to the side of the seat/back frame (see picture). The seat/back frame is visible at the junction of the seat and the back of the chair frame. The glider produced after 1994 used a one piece seat/back frame and there is no frame visible at the junction of the seat and the back
