How to Tighten Swivel Bolt on Bottom of Seat of Chair

One of the most common ways to tell how old a chair is, how often it has been used, and how much wear and tear it has gone through is by examining the swivel bolt underneath the seat. Over time, these bolts can become loose or even come out altogether.

If this happens to your chair, you need to replace them as soon as possible for safety reasons! In this post, we will show you how easy it is to tighten up that pesky bolt with just a few simple steps.


Steps to Tighten the Swivel Bolt

Step 1. Place your chair on an even, flat surface. Make sure it’s stable and won’t move around while you’re working on it!

Step 2. Remove any loose/broken parts that may be in the way of replacing a broken or missing mounting bracket (such as screws).

Step 3. Loosen the bolt on the underside of the seat by turning it counterclockwise with a Phillips head screwdriver.

Step 4. Tighten it up by turning clockwise to insert and tighten securely. If you have an Allen wrench, use that instead for more leverage! You can also try using pliers or vice grips for extra grip strength if desired.

Step 5. Recheck how tight your bolt is from time to time as they may come loose again over time due to wear and tear.


What is the knob under my chair for?

You are likely referring to the knob that you turn with your hand, located under your chair. This is how you can adjust how far or close the seat of the chair slides from one side to another as well as how quickly it moves.

If there is some wobbling and movement when turning this handle, disconnect/unscrew any loose parts on both sides (such as screws). The casters may need tightening up too!

It’s possible that if someone has been trying to pull their chair around by grabbing onto this knob then might have broken off a part connecting it. You will want to replace these pieces before anything else.

What do I do if my swivel bolt’s too tight?

Loosen the bolt by turning counterclockwise and loosen until comfortable.

How do you Adjust a evolving chair?

Adjusting a revolving chair is relatively easy. There are two ways that you can do this:

  • Loosen the nut on both sides of the armrests to make it easier to turn
  • Or loosen one side and tighten the other, for more stability in how your chair turns.



When adjusting these bolts, if they’re loose enough so there’s no pressure left on them then they will need tightening up with some new screws.

You might be looking at needing to replace those rusty old parts! It may not take much time or hassle but will save you from having problems down the road; even if it seems like nothing happened now.


What is the best way to sit at a desk all day?

Your desk should be at an appropriate height for you to work comfortably. You might need to adjust the chair height or your sitting position if those adjustments are not working well enough.

The best way to sit is usually how most people feel comfortable; there’s no perfect answer here! The key thing is that you’re relaxed and able-bodied, so can stay in this position as long as needed without feeling any discomfort.

You may want a footrest from time to time depending on how long of stretches you have been sitting in one place.

It will help with circulation and keep blood flowing through your feet which could make it easier for them later when they’ve had more exercise than they would otherwise have gotten all day!”

If resting your feet on anything, make sure it’s clean! If you’re watching TV or reading a book and just want to prop your feet up for any period of time – this is how chairs with footrests are usually used.

You might also find that if the seat height isn’t right then it can be uncomfortable too! A chair should generally come between 17-19 inches from the floor but we don’t all have the same build so there may need to be some adjustment made.


If you still feel pain in your back when sitting try these other tips:

Move as much as possible during periods at work where you’ll normally sit down; take regular breaks which will help keep your muscles active and blood flowing through them more easily; and make sure you’re sitting on a chair with good support, one that will help to keep your spine in alignment.


What is the best chair for sitting all day?

One of the most important things to look at when choosing a chair is how well it will support your back and how comfortable you feel in it.

The best chairs for sitting all day are those that allow good lumbar support, have armrests that go up high enough so they don’t dig into your armpits, and offer a seat height that’s adjustable with an easy-to-reach lever or knob on either side (or both).

Adjustable heights can be very helpful because we’re not all the same size! The lower the chair’s height, the more pressure there’ll be against your thighs which can lead to pain in them as well as creating problems for circulation.
