The present invention relates to foundation process and means, for upholstered and/or cushioned furniture, wherein at least un upright or the like, erecting, from the base to pierce the padded and cushioned reclining place and providing a frame to the stringer and/or vertical members, may be itinerated, in a continuous or stepwise way, within the furniture plan. More particularly, the present invention relates to furniture obtained with such process and means.

In the present state of the art, furniture and particularly upholstered and/or cushioned furniture are manufactured in series and used, as manufactured, without any liberty for the user to modify it. Such liberty was limited to the choice of a particular upholstery or to place in any different way the pieces of furniture. This situation dictates numerous and frequent decisive and critical choices, destined to fall in crisis as soon as the the planned events change, i.e,, in case of changes in family composition, in suit of rooms or use of same furniture in places different from those chosen. Another chance never considered was that to modify or arrange each piece of fumiture to the power of circumstances of the particular moment. The till now devised arrangements were limited to move the seat and/or the back, according to a design strictly provided by the manufacturer, for a range of potential users or costumers, who could operate changes only if provided by the designer, but this did not affect the structure of upholstered and/or cushioned furniture as designed and made.

The invention, as claimed, is intended to remedy these drawbacks. The inventors, with ingenious perception have conceived a foundation process and means, for upholstered and/or cushioned fumiture such as chairs arm chairs divans,

settees and the like, providing, according to a stepwise embodiment, a base, substantially in the form of plinth, including a series of seats, each adapted to receive, at least an upright or the like, standing to pierce the padded and cushioned reclining place and providing a frame to the stringer and/or vertical members, such as the back, the amis and the like.

According to a preferred stepwise embodiment of the present invention, the base of the piece of furniture has conventionally consistency of substantially parallelepipedic housing and is provided with at least a member, extending horizontally, including, in a number of positions, distributed over at least an important section of the fumiture plan, a number of seats in the form of dead vertical holes, having suitable shape, size and depth, to receive the bottom end of at least an upright or the like, standing to pierce the padded and/or cushioned reclining place and to provide a frame for the stringer and or vertical members and/or frame members.

In accordance with a continuous itinerating embodiment of the present invention, itineration is dynamic, and is provided to uprights, comprising the frame, by at least a generally, but not exclusively, crosswise guide, for sliding at least a chariot, including at least a seat adapted to receive the bottom end of the upright, comprising the frame of the cushioned furniture. Of course, these devices are at least two for the back. In other words, instead of itinerating the uprights in fixedly distributed seats the same, at a base level, are made itinerant by placing each of them on a slidable chariot

Some ways of carrying out the invention are described, in detail, below with reference to drawings which illustrate specific embodiments thereof, in which: .
