Benefits of technology

The present invention provides a seat cushion that can be easily attached to a mesh seat member. The cushion has protrusions that fit into voids in the mesh, and a frame component with protrusions that fit into the voids on the opposite side. The cushion can also have engagement members with a distal tip and a shaft that fit into the mesh. The invention also includes a method of making a covering for a seating surface by adding moldable materials to a mold and forming a pad component that is bonded to a rim component. The seating structure also includes a support structure and a pad assembly that is secured to the support structure.

Problems solved by technology

While providing good aesthetic properties, mesh seating bottoms frequently suffer from limited comfort and cushioning qualities.
Although satisfactory in many regards, conventional seat cushions generally utilize a flat base member which does not conform to contoured seat bottoms used in many of today's office furniture.
It is often tedious and difficult to tie or otherwise secure such tie downs or snaps, and equally difficult to release them after use, in order to remove the seat cushion.
Furthermore, fire retardancy is an increasing concern for office furniture.

Embodiment Construction

[0027]FIG. 1 illustrates a typical chair 100 with which the present invention seat cushion is used in conjunction. The chair 100 typically comprises a seat back 110 and seat bottom 120 positionably coupled together by a frame assembly 115 extending therebetween. The chair 100 also comprises first and second arm members 130 and 132 engaged with the frame assembly 115 and / or the seat back 110 by support members 131 and 133, respectively. The sub-assembly of the seat back 110, seat bottom 120, frame assembly 115, and arms 130 and 132 is generally disposed and supported on a pedestal 140 extending between the frame assembly 115 and a base 150. The base 150 can be in a variety of different forms and arrangements, however, it is typical to utilize a plurality of outwardly extending support members each having a caster 160 or other rolling member disposed on their underside.

[0028] The seat bottom 120 of the chair 100 preferably utilizes a relatively thin supporting member such as a mesh o...
