Chairs come in a variety of materials including fabric, leather, and mesh. The best material ultimately depends on your taste, but there are a few factors to consider. Leather, even the PU leather that most affordable "pleather" chairs use, tends to look the nicest, but it also wears down the fastest. It scratches and tears easily, especially if you have a pet. Fabric is usually more hardy, but is the easiest to stain and can collect the most odors. Mesh chairs are the lightest, most springy, and the least likely for pets to want to sit on. The mesh material serves as the chair's entire support structure, unlike the foam padding in fabric and leather chairs, and may not provide all the support you need.
