How a listing is chosen
A chair is included when its listing can supply a title, a main photo, and a size line you can read on the page.
Each card starts from the live listing. The title is the listing title. The photo is the main photo saved from that page. The size line is a dimension, a seat depth, or a cushion thickness that the listing itself prints. The white chair in the photo is one of those listings: the details table prints a 300 pound maximum and a 25.59 inch seat depth. If a figure is not on the listing, it is not added on this site.
Pages then sort those printed lines by the decision in front of you. A carpet page keeps the listings that name carpet. A tall-sitter page keeps the height and seat-depth lines. A narrow-desk page subtracts chair width from 48 inches. The same chair can be right for one of those questions and wrong for another, because the maximum, the floor, and the seat depth are separate sentences.
