It’s sturdy! Height adjustment is very minimal, and it doesn’t go up as high as you might think. My 65in screen mount was very exact, I had to lay the tv down on my couch and hook the stand on before standing it all up. It took about 15 minutes for me to put together. It was hard to get against the wall because once the tv is on it, it won’t budge - which is great because I have a child but dreadful because the mount fit so exact I couldn’t hang it while standing.
