The Sofa

The Sofa is the home of the Numberjacks.

Appearance
From the outside, the sofa looks like a normal sofa. It has a denim-blue colour and is usually home to an assortment of different cushions, varying from day to day. During the launching process, the sofa opens up to reveal a circular hole into the Launcher Room. The launching hole is located in the arm of the sofa.

Properties
It is not an ordinary sofa, but one with special properties. For example, it possesses a camera system to observe the room it is located in. This camera is able to be rotated to check if any humans are in the room at the time of launch. It is also able to be moved up and down and is hidden from plain view by extending seemingly from the back of the sofa. If there are humans around the sofa, the Numberjacks have the ability to ring the doorbell from the inside so as to not to arouse any suspicion when a Numberjack is launched.

An alarm to alert Numberjacks to when an agent is calling in is implemented and can be heard in every room within the sofa. Other technology in the sofa includes an elevator as a method to get to the Control Room. There are also less technologically advanced methods such as a bounce pad. In most rooms, there are also television-like screens which enable the Numberjacks to see into the outside world.

The sofa itself also acts as a normal sofa, both humans and Jasper the Cat frequently sit on it, seemingly in favor of the other two apparently normal sofas in the room.

The sofa possesses rooms such as the Launcher Room, the Gym, the Cosy Room, the Control Room, various corridors, and bedrooms for all the Numberjacks as well.

The Launcher
Main article: The Launcher

The Launcher, located in the Launcher Room, is how the Numberjacks travel from the sofa to the outside world and vice versa. From the outside, a hatch opens and closes.

The Numberjack wishing to go outside goes down a slide and is scanned first and then jumps into the correct pod, before being launched by a button situated in the Control Room. The technology in the sofa is somewhat restricted, however, as after the Numberjack has been launched, another Numberjack in the Control Room has to find one of their numbers to land on. For example, Five would have to land on a number five. An inability to find an eligible number in time resulted in them being dropped somewhere close to "where they should have landed".

Brain Gain

The sofa also has the ability to make Brain Gain, a power that is created using the Brain Gain Machine, located at the other end of the Control Room from the screens. It is created by a Numberjack jumping around inside the machine; the energy created by everybody's thoughts is then transported from the sofa to the outside was another Numberjack uses it to combat meanies. There are also screens inside the machine so that agents can also help with the process. Three once clarified "The Brain Gain Machine joins up the thinking of all the Numberjacks, the agents, and you." (as heard in All About the Brain Gain Machine)
