You can also look for a few different features that come with these trees. Some main ones include:
Flocked: This means that the Christmas tree has been treated to look like it has snow on it. This is a great addition for rustic, classic and country Christmases. It can even look good in modern Christmases or white monochrome Christmases if the flocking is heavy enough.
Pre-lit: A major feature is that many trees come pre-lit, meaning the lights are already attached to the tree. A drawback is that if the bulbs start to go, you have to replace individual bulbs or the whole tree. You also can't customize the light colors from year to year. However, it knocks off one step of putting up the tree. Some pre-lit trees are also made with fiber optics for a real light show.
Rotation: Some Christmas trees can be made to rotate. If you have so many ornaments that you can't fit them all on one side of the tree, consider a rotating tree. This feature tends to come as separate stands.
