No, assembling recliners is not at all a difficult job if done properly. Every recliner has its own specifications. All you have to do is to get the things fixed by reading the manual. A recliner comes in several smaller parts. You have to assemble them into one. There are certain lock systems that you have to place properly to get the chair ready at once. Just follow the manuals as given. If still, you are facing the problem then it is better to hire a professional.
