I found the screws with a short phillips head screwdriver inserted into the weep holes at the bottom of the cushion. Once the screws were unscrewed the backrest lifted off easily. Thank you,
Thank you! I haven't been able to find screws at the bottom of the cushion. (A few other posts suggested that I'd find them). Do I need to pull the bottom of the cushion away and then pull the cushion straight up?
