Why Do They Put Fiberglass In Mattresses?
Fiberglass is used as a fire barrier. All mattresses sold in the USA are required by federal law to contain some kind of fire barrier. This is because the foams and fabrics used inside a mattress are very volatile materials, and you can imagine the catastrophe and destruction a mattress fire could cause if there was nothing inside of it to try and mitigate the risk.
Fiberglass is a cheap option for mattress brands to use in place of potentially harmful chemicals (which are also cheap). The fiberglass fire barrier will consist of very thin shards woven into some kind of sock (either as part of the cover or a secondary cover) that will melt in on itself if a fire happens, with the idea that it will help put out a fire before the whole mattress can become involved.
Is Fiberglass OK In A Mattress?
Fiberglass inside a mattress is okay if it stays in, but if it gets out it can wreak havoc on your house and your health. If fiberglass particles get free from your mattress, they can embed themselves throughout your bedding and furniture, and will be pretty much impossible to remove.
So, the short answer is: it depends on the risk you want to take. Do you want to buy that cheap mattress and cross your fingers you don’t have a problem, or do you want to spend a little more and feel assured there’s no fiberglass in your mattress?
Basically, as long as the fiberglass does not get out of the mattress, it will be fine.
If you buy a mattress in the knowlege it has fiberglass, you can minimize your risk by not removing the cover and using a mattress protector to maintain the integrity of the cover.
BUT: the fiberglass does often get out. How?
- Fiberglass is often used in cheap mattresses, that have cheap covers. If the cover is not durable and rips or wears down, the fiberglass underneath could escape.
- Human error. A tell-tale sign of fiberglass in a mattress is a non-removable cover. The problem is, people don’t necessarily pay attention to this, and will unwittingly remove a cover and expose the fiberglass.
- This issue is exacerbated by some brands (I’m looking at you, Zinus) using a zip in the manufacturing process of their cover, which is not intended for the home consumer to touch. But it’s kind of tempting to open a zip if it’s there, right?
This short video shows you the risks AND benefits of fiberglass in a mattress. Watch to see exactly the sort of damage it can do, AND see how well it can actually stop fire.
Do Most Mattresses Have Fiberglass?
Most mattresses in general? No.
Most cheap memory foam mattresses? Yes. What’s cheap? Around $600 or under for a Queen/King size.
Remember, fiberglass is an inexpensive way to provide a non-chemical fire barrier, which is extremely important for highly flammable memory foam.
Here’s A List Of Some Common Brands That DO Have Fiberglass
This list is not every single mattress that contains fiberglass, but it’s some of the most common brands.
- Classic Brands
- Ashley Furniture
- Amazon Basics
Which Mattress Does Not Have Fiberglass?
Here’s a list of 5 great memory foam mattresses with NO fiberglass:
- Puffy. Puffy have a range of 3 awesome memory foam mattresses, all made in the USA. I talked with their customer service team to confirm there is no fiberglass inside their mattresses: instead they use a mixture of silica and wool. Learn more about the Puffy range here.
- Tuft and Needle Original. This is a great mattress if you’re looking to buy your memory foam mattress on Amazon. You get a 100 night sleep trial, which is actually quite rare for Amazon. I’ve seen their customer service reps guarantee in the Amazon questions that there’s no fiberglass in this mattress. Do note this is not the case for all T&N mattresses, I’m talking specifically about the ORIGINAL.
- Snuggle Pedic. Another great option if you’re looking to purchase on Amazon, Snuggle Pedic also offer free customizations if your mattress doesn’t feel exactly how you want it to. It’s my favorite of all the Amazon memory foam options.
- Tempur-Pedic. Can you even talk about memory foam without mentioning the original brand? Tempur-Pedic mattresses have removable covers and no fiberglass, but they do cost quite a lot more than others I’ve listed.
- Casper. Another well known brand that is sold on Amazon, this mattress doesn’t have any fiberglass. Hooray!
Here’s What You’ll Find As The Fire Barrier In Fiberglass Free Mattresses
- Organic cotton and wool (these tend to be the materials of choice in top end, natural mattresses)
