They are very light cheap plastic . They definitely are a lot shorter than in the images shown. The branches just barely hit the heights mentioned. But the actual base isn’t that tall. You definitely need to stick the base to the floor other wise it’s a little wobbly (if you’re on carpet).  They are pretty. Just quality seems a little lacking. From far away or with added Xmas embellishments, it could certainly be a great center for the living room.
