Very high quality shelves! Easy to put together. Ordered with the screws since we have a cat that is 20lb. Husband had to help me install to get everything perfect and I love these shelves! There was an issue with one being damaged somewhere in transit and the owner was so nice to assist even though I did not contact in a timely manner. 10/10 would recommend these shelves if you have plants or cats that like to lounge in the sun.
