I have tall ceilings and this was a great addition to the Billy bookcase I have in my reading nook. Also the height is great for super long hanging plants.

Material

What is particleboard?

Particleboard is made from recycled wood and sawmill leftovers – so wood pieces with the wrong shade, woodchips and sawdust become a resource instead of possibly being discarded. We use boards for things like bookcases, bed frames, sofas and kitchen frames. To protect from wear and moisture, we apply varnish, veneer or foil that adds to the furniture's look.
