Even though these chairs will all arrive at your doorstep, some self-assembly may be required from you.
The footrests seem to already be attached to the underside of the seat, and the manufacturers, in some cases, do not recommend you removing them yourself. This is because the way the footrest is designed and attached means that the attachments used are not designed to be tampered with by the consumer and could lead to a breakage.
However, since all of the chairs on our list have footrests with the ability to fold under the seat, the need to remove them completely is reduced. You can simply conceal them under the chair when you no longer have a use for them.
