  "description_excerpt": "The present invention relates to a mechanical connector and, more particularly, to a mechanical connector for furniture.\n\nLarge furniture pieces like club chairs, sofas, loveseats and such can benefit greatly from the ability to ship the furniture piece partially unassembled to allow the separated components to be nested tightly together and to ship in a much smaller carton than if it is assembled. There would be substantial cost savings in being able to ship almost twice as many units of furniture in a standard shipping container, both in shipping and in storage costs. Another advantage for single chairs would be the use of a smaller carton having the ability, over fully assembled pieces, to ship whole units by standard rate bulk-shipping methods at a much lower cost. This would be especially desirable to furniture retailers who are selling furniture primarily through catalogs or internet sites and are regularly shipping furniture over long distances. The furniture can then be assembled by the furniture manufacturer, the dealer or retail establishment and in some cases by the consumer in their home or place of business.\n\nAn additional benefit of separating the components is the cost savings associated with applying upholstery to several smaller pieces as opposed to upholstering whole assembled frames which require more hours to produce, higher skilled labor and large specialized work tables to facilitate handling and repositioning of the heavy frames.",
