The best you can do to get the right chair for your workspace is to understand everything that makes your office furniture work. Chair legs, for example, are different depending on the chair design you pick.  

Getting chair leg extenders, chair leg protectors, or any other accessory will change your product’s features too.  

Even if you don’t notice it, the legs of your chair play an essential part in everything it can do for you. That includes boosting your productivity or making the whole chair more comfortable.  

Here, you can read all the information you need about chair legs. Dive into this page before buying new chairs for your office! 

What Are The Most Common Types of Chair Legs?

There are several different types of chair legs, and all of them offer different things. 

However, not all chair legs are useful for work purposes, so you can’t get a random option just because you like its design. 

These are the most common types of chair legs you can get: 

Swivel Legs

If you’ve bought office chairs in the past, you may already know what swivel legs are. This is the type of leg you want in an ergonomic office chair.  

These legs consist of a single central leg that supports the chair and lets it rotate in the direction the user wants.  

That leg is also the center and support of the other five legs that often have casters. You can put chair leg glides on the chair’s casters to protect the floor.

Fluted Legs

Unlike swivel ones, fluted legs are not often used for heavy-duty office chairs. They don’t allow you to move throughout your office, so you will have to stand up to get to move around.  

Fluted chair legs are long and tampered with. People get chairs with this type of leg because of their appeal. That makes them great for home furniture.  

The chair legs often have grooves carved on them.

Trumpet Legs

People who get chairs with trumpet chair legs often get them as house decorations too.  

This type of leg has the shape of a horn. They have the flared end of the chair up and the smaller one on the foot.   

Why Do Office Chairs Have Five Legs with Casters?

Swivel chairs are one of the most common options you can buy for your office, and they are also an optimal one. 

Regardless of that, many people have questions about the design of the chairs. Why are their legs like that? Is there a reason swivel chairs have five wheels with casters? 

The answer is that chair developers have a reason for everything in a chair’s design, and that includes their legs.  

Having five legs makes chairs more stable and gives them more balance. The central shaft of the chair carries all its weight, which lets you keep your balance while moving around your office.  

Apart from making the chair stable and balanced, swivel chair legs let office furniture companies come up with all kinds of designs for them.  

That design variety ensures you have plenty of options to choose from for your office.  

Swivel chairs improve your legs’ blood flow while maintaining more comfort than other options on the market.  

The main benefit of having a swivel chair is the casters, though. You can save tons of time by using the chair’s casters to get to other places in your office. 

You may think it’s an exaggeration, but standing up from your chair every time you need to ask something to a workmate takes a lot of time when you analyze how many times you did it throughout the day.  

Moreover, it’s difficult for some people to focus again after they get out of their workspace. They feel like they are stopping to work, so they have trouble going back to what they were doing.

Here’s our FAQs section! Read it if you still have some concerns about how chair legs work or what you can do with them.  

How can I secure chair legs?

You can do many things to secure your chair legs and make sure you don’t have any problem with them in the short term.  

If the chair has a loose joint, for example, you can make a pocket hole in an unnoticeable part of the chair, put wood glue on its loose parts, and use a pocket screw to lock the joint together.  

Even if the chair doesn’t have a loose joint yet, people often do that to keep it from loosening in the future.  

What can I use for uneven chair legs?

Sitting on uneven chairs is annoying. Fortunately, in the evening the chair is not as difficult as people would think it is. If you want to go with the simple way, you can just put chair leg risers on its loose legs. People often use napkins for that matter, but use the risers if you have them. 

You could also cut the other legs of the chair to match the smallest one, but that would take more time and make the chair shorter.  

How long should chair legs be?

The truth is everything depends on your taste and how tall the desk you use to work is. You want the chair to match the desk’s height if you want it for office purposes.

Nonetheless, if you want it for an office, we recommend you buy an ergonomic chair. They let you adjust their height in seconds and have special features to relieve back and neck pain. Ergonomic chairs are an excellent fit for standing desks.

Standard chairs for a coffee or dining table are often from 15.5 to 20 inches.

What do you put under chair legs to protect floors?

You can put chair leg glides under your chair’s legs to protect the room’s floor from it. Although not many people notice it, chair casters are a huge threat to hardwood floors. When they wear out, they damage the floor and make it look worse over time.  

Buying chair leg protectors for your office chair will keep the floor looking neat even if you move around on your chair all day. You won’t need to do that if the ergonomic office chair you buy has casters made for hardwood floors or get a desk chair with no wheels.                       


One of the main reasons people return the office chairs they buy online is that they don’t pay any attention to the chair’s specs.  

Chair legs are an essential part of any kind of chair, so you need to pick the right one to make sure it matches your needs. Regardless of that, make sure to also get chair leg glides for swivel chair casters to keep them from damaging hardwood floors.  

You don’t need to worry if your desk is shorter than you thought since you can use chair leg risers to get them to the height you need. However, it’s better to get a height-adjustable option.
