From the easiest bases I have installed, it doesn't bother you to assemble materials, it is ready, you place it on the wall and you only put 2 accessories on the left and right behind the TV and you go and hang the TV on the existing base on the wall and simply tighten two screws from below for support and safety!! I wish all bases were this easy, also good quality, I put a 65-inch TV and it didn't sag at all, it holds firmly and level!! Whoever wants a base, don't think too much, this specific base will reward him and you will remember me and its price is very good, these go for up to so many inches with an arm and of course, they should be good...
