Description

This invention relates to furniture, more specifically office type of furniture.
Hundreds of different chairs and office-chairs have been invented, which differ from their construction and design, but often taking up a lot of space and are uncomfortable to transport. Since many contemporary offices and people's apartments are often confined, in addition to comfort, saving in space and multi-functionality are becoming more and more important. Considering all these factors, this kind of invention can be handy in small offices, schools, shops, for disabled people or in industry where is important facilitating various devices or equipment nearby.
The main difference about this chair is the unique construction of the frame, which has space between its two levels under the seat, enable the chair to carry different kind of mechanical-, electronic- and digital devices or various equipment. It also has an adjustable, revolving seat, folding back, detachable armrests and footrests, shelf, and carrying strap. Three or more revolving wheels are fixed to the frame. The chair is compact, mobile and easy to transport. The idea of the multi-functional invention is economizing the space.
The removable shelf is preferably provided to support devices or equipment on the lower level of the frame. Footrests can come handy for a child or person who sits on the chair for a longer period of time. Carrying strap enables to lift the chair up and take it to upstairs, downstairs or somewhere else.

The seat of the chair 4, back of the chair 5 and armrests 9 are covered with fabric, leather or similar material. Armrests are attached to the openings 11 on the edge of the seat 4 with the leg of the armrest 10. There are buffers 19 on the inside of the frame to support removable shelf 20 or device. The strap of the chair 12 that is made of strong fabric, plastic or metal wires can be equipped with leather or similar material handle 13 and attaches to corresponding holes 15 on the frame 1 with the metal screw 14.
