No, you don’t need any tool. Instead, it is very straightforward and relatively fast to install the Jeep seat covers. Different companies’ seat cover comes with various installation methods. Some covers need to mount by wrapping around and attach the velcro straps, whereas some need to attach hooks to the metal straps. Several covers come with separate parts for the body and the headrest part. You can separately mount them over your Jeep seats. And the good thing is you neither need any additional tools or screws for it nor open up the seats.
