Extremely light. We expected a heavier shelf. When the box arrived it felt so light, there was no way it could be the shelves we bought. However, they look nice and as long as you hang them in the studs they will hold plenty of weight and they look nice.
These shelves are good quality and sturdy. They are well designed to be easy to hang. I look forward to using them to accent several art pieces.
