i set up the bed-rails myself, if i had not glued together model plane of revel in the past I do not think I had done the job. Sometimes I had the feeling I was a carpenter while i joined the bed-rails together, HOWEVER i slept very well on my new bed-rails. This all happened despite my actual bed-rails broke apart and I urgently need a new set of bed rails. Amazon delivered very Quickly and i was glad to take the set of bed-rails the Following day. yours sincerely, Henry Gatzweiler
