So, how can we maintain the sofa to prevent it from collapsing?

Tools needed for sofa repair: air pump, air gun, spray gun, electric drill, screwdriver, wrench and supporting repair materials.

When buying a sofa, consumers can push the sofa left and right to see if the overall structure of the sofa is solid. If it feels shaky or makes noises, it means the structure is not solid. When pushing the sofa, check whether it slides freely and whether the screws are full.

If the sofa is made of decorative panels or plywood, you need to carefully check whether the two materials are firmly bonded and whether there is any damage.

Especially for sofas with steel pipe structures, the weld is a key point. Try to open the openable parts and take a close look to avoid loosening and collapse after sitting for a long time. If it is a fabric sofa with wooden structure, the main frame part generally adopts mortise and tenon structure. If you find that the internal frame is assembled with nails, you must not buy it.

When listening to furniture merchants introduce their products, in addition to the other party's introduction of their own strengths, there are some things that are avoided, such as the sponge of the sofa. If it feels uneven or has no elasticity when sitting on it, you should be careful when buying such a sofa. Secondly, pay attention to some details, such as whether the exposed metal accessories have metal burrs and sharp corners, whether the armrests of the sofa are uneven, etc.

In terms of sofa filling, sponge is generally the main material, but only high-resilience sponge can extend the life of the product. Secondly, down is also often used in sofa cushions and backpacks. It feels fluffy and comfortable. High-end fabric sofas usually choose down as filling. In the past year, natural latex has also been used to fill cushions. Its low-carbon and environmentally friendly, strong resilience, natural and odorless, antibacterial and anti-mite functions are also favored by many consumers who pursue quality of life.

The reasons for the collapse of the sofa are nothing more than the weakening of the sponge's resilience, the sinking of the sponge, the deformation and breakage of the bottom spring, the looseness of the bottom bag, the breakage of the bottom wood, etc. There are problems with the elastic parts of the sofa. Generally, the sponge deformation is less common, and the springs fall off and the wood is broken.

Therefore, when using the sofa, we must be careful not to jump on the sofa, not to sit on the sofa suddenly, not to always sit in the same position on the sofa, and try to make the sofa evenly stressed.

1. The seat leather is wrinkled

If the leather seat is wrinkled, just remove the sofa base fabric and tighten the handles on the seat.

2. The sofa backrest collapses

First, prepare the needle and thread and four buttons, unzip the sofa cushion, take out the stuffing, and then use the needle and thread to sew the buttons to the sofa cover. The four buttons should be positioned like this, with the front and back facing each other, one up and one down, as close as possible. Then stuff the stuffing into the sofa cover, and you're done.

This way, the sofa will look like new and cost virtually nothing.

3. The sofa base collapses

(1) Turn the sofa over and check whether the canvas or nylon straps are broken. If they are broken, replace them.

(2) When replacing the belt, both ends should be nailed to the wooden frame, the ends of the belt should be folded into three parts, and the nails should be nailed in a cross shape. Use 5 cm wide wooden strips along the bottom belt to nail to the seat frame.

(3) If the spring is broken, it must be replaced with a new one. First, nail the spring to the wooden beam with a small nail according to the diagram, and then use hemp rope or nylon rope to tie the springs together in a "M" shape. The tied spring should be high in the middle and low around, with the front higher and slightly lower at the back.

(4) When replacing the sack cloth, put in the filling materials such as felt and foam plastic in turn, and then cover it with the fabric. Fix each layer with nails, and pay attention to the stitching and shape.

Other common sofa problems and how to fix them

① The sofa's solid wood parts are loose. Some of them are too long or too big. When installing, the sponge pad is raised to prevent the joints of the solid wood parts from being screwed up, so sometimes they are not tightened too much. After a period of use by the customer, there is a loose phenomenon. Some of them are loosened due to the force during transportation.

② The solid wood legs of the sofa fall off mainly because the wood planks where the solid wood legs are installed are too small, or because the wood planks crack during installation.

③ If the solid wood is loose, just tighten the loose parts. If the solid wood is falling off, add wooden blocks where the feet are installed and then install it.

①The four-seater sofa and the five-seater sofa are both made up of two sofas. The main reason for the unevenness is that the sofa is squeezed and deformed by heavy objects during storage and transportation, resulting in the uneven height of the two sofas.

② If the deformation is not too serious, you can put the sofas together first, pat and press the deformed parts until they are at the same height. After being squeezed tightly by the two sofas, the sponge inside will slowly recover.

③If the deformation is too serious, remove the deformed screen, flatten the deformed area, and then put it back together until the heights are the same.

④ If it cannot be closed and is inconsistent, it is likely caused by the breakage of the wood or plywood. First, restore the broken plywood and nail it, and then add wood or plywood to the broken part and nail it firmly.

①The main reasons why the sofa makes noise when sitting on it:

1. The wooden frame of the sofa is loose and not firm;

Second, the spring at the bottom of the sofa seat rubs against the wooden frame and makes a sound;

3. The friction between the leathers makes a sound.

② If the wooden frame is loose and makes noise, first identify the source of the noise. If the wooden frame is loose and not firm and makes noise, identify the source of the noise and add nails and wood blocks to the source of the noise.

③ If there is a sound caused by friction between the spring and the wood at the bottom, you can pull the spring apart at the place where the friction occurs, or use a knife to cut off a little bit of the wood until there is no sound when you sit on it.

④ When leather rubs against each other and makes noise, you can apply leather protector on the friction area to make the leather soft and smooth, so there will be no friction noise.

①The main reasons for the sofa to become loose are:

When installing the sofa, the screws in some stress-bearing places are not tightened enough, causing the sofa to become loose after a period of use; or the holes in the sofa are too large, causing the screws to sink and cause looseness; or the sofa may be squeezed or bumped by heavy objects during transportation, causing it to become loose.

② If the problem is caused by the screws not being tightened , tighten the screws or reinforce them with self-tapping screws.

③If the hole is too large and causes looseness , first loosen the sunken screws, use a 9mm plywood or wooden square to drill a smaller hole, place it on the sunken hole, add a gasket and tighten the screws.

①The main reasons for sofa deformation are:

The sofa was not stored as required during warehousing; the loading was unreasonable during long-distance transportation, too heavy products were placed on the sofa, and it was deformed due to long-term squeezing by heavy objects; it was caused by improper use by the customer.

② When storing, the sofa should be placed flat or stacked in layers on a metal rack, which can save space and prevent the sofa from deforming. When loading the sofa, the sofa should be placed on top of other products and not stacked too high, which can reduce the deformation of the sofa during long-distance transportation. When using the sofa, customers should not sit on the armrests of the sofa or press hard on the backrest to avoid deformation of the sofa.

③Repair methods for sofa screen deformation:

Sofas with deformed screens are generally wrapped with the screen. First, understand the installation structure of the sofa. The armrests are detachable, so remove the armrests first, and then remove the screen package. Pad the deformed area with sponge or spray cotton, and make the flattened area feel the same as other places. Then install the package in the order of disassembly.

④ Repair method for deformed handrails:

The sofa with the armrests covered is prone to deformation. First, distinguish the structure of the sofa. If the armrests are detachable, remove them directly. If they are not detachable, remove the seat or screen together. After removing them, pad the deformed parts with sponge or spray cotton to ensure a good feel after padding. After padding until it is full, cover it with the bag.

⑤Precautions for disassembly and assembly:

First, remove the solid wood legs with an electric drill, and then remove the bottom cloth with a screwdriver. Be careful not to tear the bottom cloth when removing it. Check the structure of the screen frame, how many screws there are, and whether there are self-tapping screws. If there are self-tapping screws, loosen the self-tapping screws with an electric drill, and use a wrench to remove the screws on the side of the screen first, and then remove the screws at the bottom. The method of disassembling and assembling the sofa with disassembled armrests is the same as that of the screen; for sofas where neither the armrests nor the screen are disassembled, pay attention to first removing the solid wood legs and bottom cloth, and then check the handle cloths on various parts of the sofa. Then use a screwdriver to remove the handle cloths on various parts (be careful not to tear the handle cloths when disassembling and assembling), flatten the deformed areas, and then touch them in the order of disassembly.
