Have you ever used an annoying squeaky chair? It is a source of great disturbance for both the seated person and others in the room. Luckily, there's no need to buy a new one; by correctly diagnosing the source of the problem, you can easily remedy it.
Steps
Method 1 of 2: Oil the Metal Parts
Step 1. Inspect the nuts, bolts and screws
The first thing to do is turn the chair over and look at all the small parts. Get a screwdriver or wrench and tighten any loose items. you should try to tighten even those that seem to you in order. Over time it is very likely that the screws and bolts will move a little, causing friction between some parts that contact irregularly and emit the squeak.
Step 2. Grease the mechanisms
Apply lubricating oil to all nuts, bolts and screws to improve the action of the joints; just spray the product directly on the moving parts and pat them dry. You can also pour the lubricant onto a soft cotton rag and rub it on problem areas for greater control of the procedure.
Air humidity and air conditioners can promote rust formation; applying the oil regularly prevents this from happening and oxidation build-up
Step 3. Remove all hardware completely before applying lubricant
If the chair still squeaks after tightening all the bolts, screws and nuts, unscrew them and lubricate them with a light engine oil before putting them back in place.
Step 4. Ask a friend to sit in the chair as you go
To better identify the areas that emit the noise, a person should sit down and roll the seat a little from side to side. By creating pressure to purposely induce the noise, you can locate the source of the squeak more easily and apply the oil more accurately. Have the person move around in the chair every time you splash to see if you've gotten the right amount of weight.
Step 5. Repair the back springs
The chair may only creak when you recline, which happens when there is too much tension where the ends of the springs rub against their seat. To manage this problem, grease the tension springs located inside the adjustment knob; simply unscrew this knob, remove it and spray the lubricant inside.
Step 6. Move the chair back and forth to inspect the casters
Office chairs often have wheels that move a lot, and over time it is quite normal for their pins to need some silicone lubricant. Turn the chair over and apply the product on the wheels; then bring it back to its normal position and move it in different directions to spread the product evenly inside each wheel.
Step 7. Sit down gently
Leaning heavily on the chair could cause the squeak. This furniture is subjected to a lot of wear; to ensure that they remain "silent", you should treat them with care so as not to accelerate the aging process and prevent the joints from loosening.
Method 2 of 2: Repair a Wooden Chair
Step 1. Inspect the chair for loose screws, nails or legs
Check if the legs and the backrest move excessively by pushing and pulling them to quantify the "play"; in theory, they should be immobile.
Step 2. Turn the chair over
You can place it on a table or other chair, so that you have better access to the problem area; in this way, you avoid putting unnecessary pressure on your legs or backrest while you try to repair them.
Step 3. Apply glue to unstable joints
There are numerous types of strong wood glue that you can purchase and use to secure the chair legs. Once you find a loose joint, insert the adhesive into it and wait for it to dry completely before turning the chair over. Rub away any excess glue dripping from the area using a wet cloth.
To make the glue thicker, add a little wood putty; this compound stabilizes the legs better than a wobbly chair
Step 4. Expand the spikes with special liquids
To fix very loose components that seem to need more than a few drops of glue, you must first completely disassemble the chair legs and use these products; sometimes, the spines shrink and weaken the joints. When you apply liquids, they make the wood expand again, so that each joint fits perfectly, making the seat safe.
Step 5. Replace the nails or wooden dowels
If the small parts seem very loose or otherwise unusable, you need to replace them; Even if you don't want to remove the existing nails and screws, consider adding more reinforcement or applying brackets to stabilize the chair. When inserting more screws, make sure they are long enough to join the pieces together securely, but not long enough to stick out on the other side of the wood.
