Simple and easy to set up. I absolutely love this tree! It looks so realistic and full, and once it's set up, it gives the room that beautiful Christmas-tree look without looking artificial. The branches have a natural appearance, which makes it really easy to decorate. One of my favorite things is that it comes in 4 parts, which makes putting the tree together much easier. I also LOVE that it already has lights built in! You can switch between the different colored lights or classic white lights, depending on the look you want. I love having the option to change it up. I love this tree and can't wait to decorate it!
