An antique desk chair can be an expensive item to purchase, so there are several factors to consider. First, you should consider the type of desk you will be using it at, and try to find one with the same wood tones if possible. Make sure there are no large cracks in the chair and that it is solidly constructed. Check to see if the seat wobbles from side to side when you sit down in it. If the piece has casters, make sure they roll easily.
The vintage desk chair you select can largely depend on the other office furniture you have. Look your desk over carefully to see if you can identify the manufacturer. That way, you can choose a chair made by the same company. If this information is not available, consider the type of wood and overall design of the desk when making your selection.
Check to see that the antique desk chair is still usable. Inspect it carefully for signs of cracked wood or broken pieces. Some imperfections are acceptable, as long as it does not affect the quality of the chair. Hairline cracks or slight nicks in the surface will not render the piece unserviceable.
Look at the chair in order to get an idea how well it is made. Make sure the legs are securely joined to the seat and that the back is also securely attached. If there are arms on the antique desk chair, make sure there are no rough edges on them that could injure someone.
Sit in the chair to make sure it is comfortable and sturdy. Move back and forth in it to see if the seat wobbles. If there is an excessive amount of wobble, that particular antique desk chair may not withstand a great deal of use.
Some vintage chairs have casters or wheels on the bottom. If the one you like does have wheels, make sure they are in good working condition. Roll the chair around the room to see if the casters move freely. Look them over for signs of rust. If they are extremely corroded, you may want to consider replacing them.
Many models may not have modern features such as a lever for adjusting the height. Keep this in mind when you are shopping. Even though an antique desk chair may not have many extras, you can often still find one that looks nice and is comfortable to sit in if you shop carefully.
