That is strange! I have never opened a piece of furniture and seen anything like that before, but I did find this video to see what it looks like… Is this what yours looks like? I’d love to see pics so I can better assist you. If you are a member of the LullCo Upholstery Club (my private group on facebook) you can post your pics or video there and tag me in a post! I’m happy to answer, plus we have a lot of other more experienced pros in there too who may be able to help.
