Definition of Fiberglass

Fiberglass refers fine fibers that are formed from combining plastic and glass. The material is first heated to a molten state and is then spun into a fine filament, which is finished as woven sheets. These fibers can be flattened into a thin sheet, woven into glass cloth, or randomly combined into different valuable glass fiber varieties. It is worth noting that the raw materials used for fiberglass are no different than those used to make kitchen glass and window glass. It is the production process that gives this substance the form you are familiar with.

Potential Harmful Effects of Fiberglass on the Human Body

Although the fiberglass is non-toxic, we cannot 100% promise this material would not be harmful to us. The manufacturer usually sews a tag with "Do not remove cover" to warn against removing the cover, because they clearly know that doing so would expose the fiberglass layer underneath. We can also search for approximately how many people were injured when the cover was removed because they did not pay attention to the tag or just wanted to clean the mattress. Many people do not expect the incident to happen. If you've ever touched the fiberglass insulation before, you would know how itchy it can be on your skin. The worst part is that once fiberglass comes off your mattress, it's almost impossible to get rid of. In fact, it can get to anywhere in your home - air, carpet, furniture, clothes, everything. It's everywhere, just like dust, except it's made up of tiny pieces of glass. This makes fiberglass cleanup both expensive and painful. One cleaning professional said that depending on the severity of the situation, it could take anywhere from thousands to tens of thousands of dollars to remove fiberglass from your home.

Why Do You Need Fiberglass-Free Mattress?

Why Do You Need Fiberglass-Free Mattress?

Breathe Easier And Sleep Better:

Fiberglass-free mattresses provide a healthier sleeping environment by not releasing potentially harmful particles into your bedroom. This means you can breathe easier and sleep better, knowing that your mattress is fiberglass-free. So, it's crucial to look for a mattress that is certified as fiberglass free.

Safer For Children:

Children are especially vulnerable to the risks posed by fiberglass-filled mattresses. A fiberglass-free mattress can help keep your little ones safe and healthy while they sleep, giving you peace of mind. Most parents usually select mattresses with certification mentioning the absence of fiberglass.

Reduce Skin Irritations:

Recent studies have found that exposure to fiberglass particles can cause skin irritations. If you have susceptible skin, you must be extra careful when purchasing a mattress. Also, ensure the fabric is fiberglass-free to avoid skin irritation and get a good night's sleep.

How To Spot a Mattress with Fiberglass?

Check the Label

Generally, the label would include the main materials used and their proportion of use. When we choose a mattress, we should pay more attention to the material of the mattresses. But there is a special case, due to strict laws, which vary from country to country, products need to have material labels. Some manufacturers would use ambiguous information on the label or make it very difficult for the buyer to access the information. Therefore, it helps to check and ask for the information before purchase.

Check the Manufacturer's Instruction

To avoid the situation mentioned above, we should carefully read the manufacturer's instructions carefully; if it says, "Do not remove the cover," it is most likely because the mattress contains fiberglass. Some mattresses have zippers on the cover despite the "Do Not Remove Cover" warning; such zippers do not invite you to remove the cover, but are part of the manufacturing process; therefore, if you encounter a mattress with a zipper or "Do Not Remove Cover" warning, you should avoid touching the zipper and opening it up.

What Should We Do If Our Mattress Has Fiberglass?

Never Remove the Cover

Never Remove the Cover

We already know there is a fiberglass layer under the mattress cover that acts as a flame retardant, removing the cover would expose the fiberglass to the air, carpet, and clothes. Exposed fiberglass is also prone to injury to our skin and is very difficult to clean.

Use Mattress Cover

Use Mattress Cover

As long as the fiberglass is inside the mattress, you can continue to sleep on your mattress. To keep the fiberglass being kept inside, a mattress cover can act as a protector, which can help contain any debris and loose materials inside the mattress, which helps the fiberglass from spreading.

Replace the Mattress

Replace the Mattress

If you’ve noticed your mattress is already worn and the fiberglass can leak through, replacing the mattress would be a safer option.We suggest that you consider how you dispose of your mattress so that it does not affect the health and safety of others. Many mattress recycling programs have been established to reduce the number of mattresses going to landfills, and parts such as steel springs can be repurposed into other items.

It is hard to recognize the mattress with or without fiberglass because the fiberglass is woven into the mattress, making it a challenge to identify it with the naked eye. When buying a mattress, you can also look for health and quality certifications that ensure that the material will not cause adverse health reactions or expose you to harmful substances. If you're on a budget, low-cost mattresses may be attractive, but they will inevitably sacrifice the quality of the mattress and the related certification. It is important to find a mattress that is nationally certified and eco-friendly on a limited budget.
