Sofa book folding mechanism: types and methods of replacement

Repairing a sofa with your own hands is not as difficult as it seems at first glance. Even high-quality upholstered furniture becomes unusable after a while, because the springs are often deformed, and the wood frame can crack due to heavy loads. Yes, you can buy a new sofa, but such a purchase can significantly affect your budget. But don’t despair, because many damages can be corrected by repairing and reupholstering the sofa.

Sofa repair at home

Below we will look at the main problems that require repair work to restore the sofa.

Frame and transformation mechanism: step-by-step instructions

First of all, you need to check the condition of the sofa frame. To do this you will need to disassemble the structure.

Step one: you need to disassemble the sofa, remove its upholstery and filling. After that, you should carefully remove dirt and dust that accumulate inside the structure over time. In some designs, the transformation mechanism is attached to the seat and back, and in this case there is no need to remove the upholstery.

Dismantling the sofa

Step two: now you need to inspect the condition of the frame beams. They are often deformed due to various impacts. If they are cracked or broken, it will be necessary to prepare the bars exactly to the size of the structure and install them. A cracked beam can be fixed using a metal angle and screws. As you can see in the photo, a fairly large number of fasteners will be required for the grip to be reliable.

We connect the parts of the beam with a corner

Step three: in some cases it becomes necessary to replace the plywood part of the sofa. The damage occurs because the springs push through the thin plywood.

Any cracked pieces of plywood will need to be removed.

Now we need to cut out a piece of plywood exactly to the size of the damaged part (in this case we use a diameter of 4 millimeters)

We prepare small bars and make holes in them for self-tapping screws

Now, using self-tapping screws and wooden blocks, you will need to secure the plywood part

Repair of the transformation mechanism will differ depending on its type:

1. Book. A common problem with this mechanism is the breakage of the rivet on the guide bar. To make repairs, you must disassemble the structure, secure the mechanism with clamps, and then remove the rivet and replace it. If several parts become unusable at once, then the entire bar is replaced.
2. Accordion. There are many miniature parts in this system, so it will be very difficult to carry out repairs yourself. Most often it is necessary to change the roller or its wheel; the lamella fasteners also often become unusable, so they are replaced with purchased ones.
3. Click-clack. Damage to the housing occurs in the seat areas, causing the lock on the transformer to stop working. It cannot be restored, so you will need to install a new one.
4. Roll-out. In this model, rollers are usually replaced, because they are often made of low quality materials. This mainly applies to plastic products that rapidly deform under pressure.

Very often, budget versions of sofas are equipped with a roll-out mechanism

There are cases when the fittings of the transformation mechanism have not lost their original appearance, but the spring requires replacement. It usually becomes deformed when there is too much load on the sofa. If there are deformed parts in the design of the mechanism, they must be removed and replaced. Let's look at the repair process using a clear example.

Step one: remove the spring from the transformation mechanism.

Step two: now we need to disassemble the latch.

Next, take the bolt and clamp it with a vice.

Spring block repair: step-by-step instructions

During operation, it is the spring unit that often fails. It consists of twisted metal elements connected at the top and bottom. The first sign of a breakdown is a characteristic creak that can be heard when trying to sit on the sofa.

Important point! Restoration of the spring block is carried out by replacing the connecting parts.

Step one: in this case, you will have to remove the upholstery and all the soft part using a special tool called an anti-stapler.

Step two: now you need to determine the type of breakdown and fix it:

1. If the metal elements are disconnected from each other, they can be secured with wire. It is important to remember that the pointed parts of the wire will need to be bent inward.
2. If the entire spring block has become unusable, then there is simply no point in repairing it, because after a while it will begin to creak again. Therefore, in this case, all that remains is to purchase a new one.

You can connect broken springs together using wire or a spring. In this case, a dowel was used as additional reinforcement.

If, during operation, creaking is observed only in a certain place of the structure, then it makes sense to secure the lining between the metal elements. Of course, this is just a temporary measure, so if possible, the block will still have to be replaced.

Replacing filling and upholstery: step-by-step instructions

Over time, not only the frame elements and springs become unusable, but also the soft part of the sofa, and then it will also need to be replaced. We tell you how to do it correctly.

Step one: we need to evaluate the appearance of the fabric that is placed under and on top of the spring block - this can be either felt or batting. Thanks to the presence of such a lining, the springs will not push through the foam rubber and rest against the plywood parts. When dismantling old structures, craftsmen in most cases see the following picture. The batting layer has become deformed and lost its original appearance, so it will not be possible to leave it. Once you have removed this material, it is recommended to vacuum the structure to remove any remaining dust.

Old content

Step two: First, material should be placed under the spring block. It is not necessary to buy a new piece of fabric for such purposes, because you can even take an old, clean blanket.

We lay the fabric under the springs, and then secure the block to the frame

Step three: now we also have to put material on top of the spring block. We will use felt for such purposes. If this is not available, you can use unnecessary carpeting.

It is advisable to roll it in two layers, then cut it exactly according to the design parameters. Now we need to attach this material to the springs using a thick needle and thread (some craftsmen use an awl in such cases). Between stitches you should leave a step of 35 centimeters.

Attaching the material to the spring block

Step four: now we have to lay down the foam. If the old one looks normal, then you can leave it. Replacing foam rubber involves performing the following steps:

1. You need to purchase filler about 40 centimeters thick. The better the quality of the foam, the faster it returns to its original shape when you press it, so it is advisable to choose an option with a dense structure.
2. Now you need to cut a piece of foam rubber to the size of the structure and attach it using a stapler and staples.

We carefully fix the foam rubber on our structure

Step five: now you need to put a padding polyester on top of the foam rubber; if necessary, it can be replaced with another soft material. As an alternative, you can use holofiber - this material is durable and has a long service life. The synthetic winterizer is also secured to the structure using brackets. At the same time, it is recommended to glue it to the foam rubber, because during use it can slip. Now the structure must be left for several hours until the glue has completely dried, and only then can you proceed to another stage.

Applying padding polyester

Step six: we have to secure the upholstery fabric. You can use the old one if it looks normal. However, many craftsmen prefer to make new upholstery to update the sofa.

If you plan to use old upholstery, you will need to wash it.

At this stage we have to choose the material from which the upholstery will be made. To do this, we will look at the features of the most popular types.

Table 3. Types of upholstery

To cut out new upholstery, you need to remove the old covers, rip them apart at the seams, and then iron them, after which new upholstery should be made from them

Now we have to secure the upholstery on the sofa using a stapler. The fabric should be slightly stretched.

Fastening the upholstery

In order to preserve the upholstery of the sofa, it is recommended to sew a set of removable covers - they can be removed and washed at any time
