A worrying video from Tiktok prompted people to open mattresses and look for fiberglass driven by fear, but experts warned the public not to check it at the beginning.

Cody Jacob first recorded his fiberglass mattress journey in December 2022, attracting the attention of millions of people.

Jacob began to develop rashes and other health problems, and found that this was related to the fiberglass particles on his bed, as he shared on TikTok, which scattered on every surface of his room.

Jacob told the Insider website that when he opened the zipper of the mattress cover, the fiberglass inside the mattress scattered in his room, and he was not aware that this action would release particles into his room.

Jacob said in an interview with Insider website, "As long as you open the zipper and don't even remove the lid, the clothes will fly everywhere." "It spreads like tiny dust particles

Jacob also requested another mattress company he liked, Casper, to give him a mattress without fiberglass.

Experts from the sleep company Every Night say that fiberglass can irritate the skin, exacerbate allergies and asthma.

So why do so many mattresses have them on them? Experts say it can also prevent another danger: fires.

According to experts every night, fiberglass can serve as a "flame barrier" to prevent mattresses from quickly burning in a fire.

Glass fiber is very attractive because it is cheap, non-toxic, and also provides protection to save people's lives in fires, "the expert said in a press release about this material every night. However, fiberglass has been criticized as a material that is not entirely harmless

Eric Rodriguez, CEO of Insider Research, told Sleepopolis that fiberglass is safe to put in a mattress, but once people open the mattress for inspection, it can 'cause serious damage to your house and health'.

Jacob's TikTok made others wonder if the same situation existed, and other viewers desperately warned people not to check.

An audience member said, "Now I'm thinking, is it because my mattress is made of fiberglass that I have a rash all over my body? How sensitive my skin is

I'm glad I caught it before it spread everywhere. I'm 99% sure it made my son sick

Sleepopolis experts suggest that anyone curious about what is inside a mattress should read the label and not open it.

Jacob told his audience that Caspar reached out and gave him a different mattress - a mattress without fiberglass.

For consumers, understanding what they are buying is really important; but I also believe that the bigger issue is that such things could have happened already, "Cody said in an interview with the Daily Dot. Of course, being an informed buyer is one thing, but simply because I want to wash the detachable cover of the mattress and have it coated with fiberglass is unacceptable
