If you’re searching for the best chair mat for your workspace, then you’re most likely to be confused by the sheer number of different types of chair mats in the market. 

You’ve probably heard that tempered glass office chair mats are incredibly smooth and durable. And they allow the office chair wheels to roll around smoothly. But, the issue is that a lot of people have safety concerns when it comes to tempered glass. 

Now, the question is, are tempered glass mats safe? Chair mats made of tempered glass are remarkably safe and you can use them without any hesitation. As this type of glass mats are  made out of reinforced glass, they can definitely take a beating and hold up to 1000lbs of weight. Even an exorbitantly high amount of force/pressure cannot break or shatter these glass mats. 

In this article, I will be taking a deep dive into all the integrated details about tempered glass chair mats. We’ll talk about all the safety concerns related to tempered glass chair mats. 

Hopefully, by the end of this article you’ll get to know just how safe tempered glass chair mats really are and should you really get one? So, without any further ado, let’s begin! 

Can You Use Tempered Glass As a Chair Mat? 

The tempered glass used to build the glass chair mats are highly durable, smooth and scratch resistant. That’s why they are easy to clean and they are compatible with almost all types of surfaces such as tiles, hard floors, carpets, marble or hardwood. 

The most crucial feature of the tempered glass used in the construction of glass chair mats is that they can support up to 1,000 lbs. of direct stress. So, even if you take a piece of tempered glass, you won’t be able to use it as a glass chair mat. 

If the tempered glass you’re using has less stress-resistance, then the glass could break and lead to an accident. 

However, if you do manage to get to hands of tempered glass with a maximum weight capacity of around 1,000 pounds, then you can cut it up at a size of 48”x60” and use it as a chair mat. 

Will Glass Chair Mats Break?

You probably haven’t realized it as of yet, but tempered glass is actually unexpectedly strong and durable. That’s what makes them scratch-resistant and guarantees that they won’t break. 

Although sometimes tempered glass chair mats get scratched when gritty substances (like sand) get stuck between the wheels of the chair and the mat, they won’t break that easily. 

You have to expose the glass mat to a pressure of over 1,000 pounds in order to break it. So, there’s no need to worry about your glass chair mat breaking.

How Much Weight Can a Glass Chair Mat Hold? 

As we’ve mentioned before the popular glass chair mats in the market are capable of holding a maximum of 1,000 lbs. However, that figure is not set in stone. The maximum weight capacity of a glass chair mat can vary from 500 lbs. up to 1,000 lbs. 

The manufacturers of glass chair mats put the chair mats under 10,000 psi of pressure while testing the products.

In real life, a glass chair mat is expected to face a weight of around 250-400 pounds. 

Is Tempered Glass Toughened? 

A lot of people get confused between tempered glass and toughened glass. Just to clarify, these two words refer to the same thing. Regular glass is toughened in order to make it five times stronger. 

This toughness is achieved by heating the regular glass at the extremely high temperature of 650°C. After that the molten glass is cooled down very quickly. 

In other words, tempered glass and toughened glass are the same and they both refer to a type of safety glass that is processed by controlled thermal and chemical treatments. This is done to enhance the strength of the glass by many folds. 

What Are Chair Mats Made of? 

Actually, glass mats are made out of various different materials and each of them has its own merits and demerits. The most commonly used materials in the construction of chair mats  are plastic, rubber, polycarbonate plastic (PVC) and of course tempered glass. 

While PVC is best suited for carpets, tempered glass chair mats are so versatile that they can be used on any type of surface. 

What Is the Purpose of a Glass Chair Mat? 

The principle purpose of a glass chair mat is to protect your hard floor/carpet from the scratches and damage caused by the wheels of your office chair. Furthermore, glass chair mats are much stronger than cheaper plastic options and they are built to last. 

Finally, they are just so comfortable to use. The smooth surface of the glass chair mat lets you glide over it with ease. It doesn’t even bend, crack or warp! 

And the important part is you don’t need to worry about flattening the glass chair mat like you need to do on a plastic chair mat. 

Can you Use a Tempered Glass Chair Mat on Carpet?

You can use tempered glass chair mats on carpet. Tempered glass chair mats work really well on carpets. Tempered glass chair mats work and look even better than plastic mats and give better smoothness and mobility for rollable office chairs on carpeted floors.

However, for high pile carpets, thicker tempered glass mats are a better choice. We have written a whole article on using glass chair mats on Carpeted floors. You can check it by clicking here.
