Most people purchase desk chair covers to add to the stain resistance of the chair, cover up a hole or tear, to simply improve the aesthetic of the chair. You must first decide what you will require from your desk chair covers, and then find some covers that will fit your model of chair. If you are searching for desk chair covers just to improve the aesthetic of the chair, your search will be quite simple: find a pattern you like and purchase the one that will fit your chair. If, however, you are looking for more features, you should outline what your requirements are and find the materials you need at the cost you want to pay.
Regardless of the type of the desk chair covers you are considering, be sure to choose one that fits snugly around the chair and does not shift when you are sitting on it. Shifting covers can cause discomfort over time, and the cover may even come completely loose from the chair. Most covers feature elastic, Velcro®, or tie downs to prevent the cover from moving. Be sure to choose a cover that fits snugly and can be removed and installed quickly and easily. Some covers feature tie downs that are visually appealing, too; they may appear as bows on the back of the chair, or they may be elastic edges that appear as a skirt around the seat bottom.
Consider the type of materials used to construct the desk chair covers. Some materials are quite simple, natural fibers, and when liquids or foods are spilled on the materials, stains may appear. Some synthetic materials are stain-resistant, making the cover easy to clean should liquids or foods be dropped on them. Some natural fiber covers can be removed easily to be washed in a washing machine, and others may even allow for the use of stain-resistant treatments. These treatments can be sprayed onto the fibers to help prevent water and stain damage, though you will need to research whether the cover material will react well to this type of treatment.
A few types of desk chair covers are even designed to improve one's posture. The cover will feature a lumbar support pad, which adds lower back support to a chair. The pad helps put the spine in a neutral position, and can make sitting for long periods of time much more bearable. It may even prevent muscle pain and aches in the neck and shoulders.
