Mine are three feet off the ground and mine are level. It does stop the posturing for position on the top rung. I have heavy and light weight breeds and they all can get up on it with a squat, jump and a few flaps of the wings. A ladder can always be made or a good size tree stump or other type of helper if need be.
You can go to all 2x4's if you want but give it a try with the tree branches. The more level they are the better.
