CROSS-REFERENCE TO RELATED APPLICATION
 This application claims the benefit of Korean Application No. 10-2011-0009279, filed on Oct. 19, 2011, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
 The present invention relates to an office recliner, an office chair having the function of a recliner. The gas cylinder for adjusting the backrest's angle is placed in the chair's central frame. Such structure secures a space for the footstool, which is necessary to take a rest, to be inserted in the seat part. The backrest can recline backward up to 160 degrees. The footstool, which is necessary when taking a rest, can be pulled out of the seat part. When the footstool is pulled out, the unlocking mechanism of the footstool panel is automatically unlocked. As the footstool panel is unlocked, the gas cylinders under the footstool panel lift up the footrest, providing the user a comfortable angle for his or her legs.
 Generally, combining an office chair with the function of a recliner makes the chair very big, or the user may require a separate footstool which takes up extra space in the room. Such composition makes it very hard for the user to use such a chair in a small office or a small room.
SUMMARY OF THE INVENTION
 The present invention, which is to solve said problems, relates to an office recliner. The user can use the present invention as a normal office chair under normal circumstances. The footstool is hidden inside the seat part. Since the footstool is in the seat part, the user does not need to rush to get a footstool. Since the footstool is inside, the user can use the present invention as a normal chair without disturbing the office environment. Since the footstool's place is in the seat part, the user can save the space for an extra footstool.
 As stated above, the present invention achieves the following effects: first, the backrest angle is undetermined and the user can set the angle to any angle of the user's choice; and second, with one simple action of pulling, the footstool is pulled out and the footstool panel is lifted up. The present invention, an office recliner, can be turned into a recliner from an office chair with said two simple actions. While working, the user can sit comfortably on the office chair, the present invention in the form of an office chair. When the user wishes to rest, he or she can enjoy the second form of present invention, the recliner, with two simple actions.
 The present invention, the office recliner, relates to an office chair with a combined function of a recliner. Normally, the present invention is used as an office chair. When the user wants to rest, the user, with simple operations, can turn the present invention into a recliner. The backrest reclines back up to 160 degrees with a push of a button. The footstool is hidden in the seat frame when the present invention is used as an office chair. It can be pulled out easily by its sliding system. The said system allows the user to use the present invention normally as an office chair and as a recliner when needed. And when the user requires a full rest, the user does not have to stand up to get a footstool to stretch his or her legs, since the footstool is already there. All the user is required to do is to pull out the footstool and push a button to recline.
 When the user wants to take a rest, all the user needs to do is just push a button and recline back. When the user wants a footstool, the user is just required to pull out the footstool. A resting environment is set by just two actions. When the user wants to resume working, the user is required to do just the reverse of those two actions.
