Sofa Frame Construction: Its Significance in Upholstery

Sofa frame and general furnishings construction is an extremely essential factor in upholstery and upholstered furnishings. The majority of people take a look at a magnificently upholstered sofa or armchair and do not see what lies underneath it. The exact same is true of a human being. The external look of a person is identified by the muscles that lie below the skin. These muscles are no stronger than the skeletal bone structure upon which whatever else is developed.

The skeleton of a sofa or a chair is its wood frame. We are going over traditional furnishings here, not items made from tubular steel and synthetic foam cushions. A sofa frame need to be strong in order to bear the stresses and stress involved when it is used. For a sofa to be comfy, it must be able to endure these stresses without drooping.

Furniture Construction: The Sofa Frame

What applies to a sofa frame also applies to a chair. The sofa frame should be constructed from strong wood. The wood ought to not be so difficult that it can decline blue upholstery adds. Frames that are joined with nails or glue tend to be weak and have only a restricted life. The greatest wooden sofa frames are built utilizing traditional jointing techniques.

The main rectangle-shaped frame should be formed utilizing thick strong wood beams, joined at each corner with mortise and tenon joints. Dowel-reinforced butt joints will eventually split up, and dovetail joints disagree for this kind of thick structure. The wood needs to be thick for 2 factors: a) it needs to hold the weight of those resting on the sofa, and b) it should provide a strong base for tacking on the webbing holding the springs and the covers.

The sofa frame will function as the skeleton for the whole sofa, supporting the seat, the back, and the arms. It is typically crafted from oak or occasionally a dense kind of softwood such as certain types of pine. This structure is the most important element of furniture construction.

Sofa Seat

Seats on the sofa will typically be supported by a layer of woven webbing. Upholstery webbing strips of 2" or 5 mm width are tacked to the side, front and back frames and woven throughout and lengthwise. The lengths are fixed to the frame utilizing 3/4 inch upholstery tack. A web extending tool is required to get the webbing to the right tension.

Steel coil springs are then connected to the webbing utilizing upholstery twine. The tops of the springs are linked using lengths of upholstery spring twine tied to the top of each spring. Each spring is connected to its next-door neighbor utilizing the very same length of twine. They are tied eight methods, connecting all the springs together and the lengths of twine are tacked to the side, back, and front rails of the sofa.

A canvas cover is then put over the springs, extended, and tacked to the side rails. The layers of stuffing and padding are then included followed by a 2nd layer of canvas to hold everything together. The top upholstery cover is extended over and tacked onto the side rails.

You can now see the value of furnishings construction, and why the rails of the sofa frame need to be so strong and well jointed. They hold every layer of the seat, including the springs, and have a large number of upholstery tacks hammered into them. The rails then need to bear the weight of at least two people, or even more for a bigger sofa.

Sofa Back

At one time, the back of the sofa was built and upholstered in exactly the same way as the seat, however utilizing shorter springs. However, to conserve time, a box spring construction is now used. The springs are held in a metal structure that is nailed to the back frame. This approach can be used because the back has less weight to bear than the seat.

The upholstery layers are then added and added to the back frame as regular. The back frame need not be as strong as the seat, and the wood used is generally of lower measurements all around. The joints of the back to the seat and arms should be strong to avoid the back frame from collapsing back.


A sofa frame must be made from strong, thick wooden beams and crossbars. They must be correctly collaborated utilizing mortise and tenon joints since they have a great deal of weight to bear and likewise a great deal of upholstery adds to accommodate. The wood can not be too soft or the tacks will not hold, nor too difficult or the tacks will fail to penetrate. Oak, cherry, and specific types of pine are fine.

Furniture construction is very essential in upholstered furnishings. Unless it is adequately strong it will not have the necessary strength. The sofa frame must last over 100 years and endure numerous sofa reupholstery episodes. The springing, if properly carried out, should itself last over 100 years. Only the padding and leading covers must require replacing in a well-constructed sofa or chair.
