Ever wonder what’s actually inside your mattress? At Big Fig, the answer is simple — no fiberglass, no fillers, no question marks. We believe what’s under the surface matters as much as how it feels on top. Every Big Fig fiberglass-free mattress is engineered for comfort, safety, and strength that lasts. Because you deserve a bed built with integrity, not shortcuts.
What makes fiberglass such a problem in the first place? Let’s take a closer look at why some mattresses still use it, and why skipping it altogether is the smarter choice for safer, longer-lasting sleep.
What is Fiberglass and Why is it Used in Some Mattresses?
Fiberglass is a synthetic material made from tiny glass strands. It’s lightweight, inexpensive, and heat-resistant, which is why some mattress manufacturers use it as a fire barrier beneath the fabric cover. It helps them meet federal safety standards — but it’s not always the safest choice for sleepers.
So, why do mattresses have fiberglass? The simple reason is cost. Fiberglass is cheap and effective at slowing the spread of flames, so some companies use it instead of investing in safer, higher-quality materials. The problem is that those same fibers can escape if the mattress cover is removed or wears thin, causing potential irritation and contamination throughout your home.
If you’re comparing brands, it’s worth knowing which ones take a safer approach. Explore which mattress brands don’t use fiberglass in their beds to see how Big Fig stacks up.
The Hidden Risks of Fiberglass in Mattresses
A fiberglass mattress might check the box for flammability, but it can create bigger problems in daily life. Countless investigative studies and reports prove that if those glass fibers escape into the air, they can irritate the skin, eyes, and lungs, and once released, cleanup is challenging. Fiberglass particles cling to fabrics, carpets, and air vents, spreading quickly and settling deep into your home.
Even small amounts of fiberglass can cause itching, rashes, and respiratory discomfort — especially for those with allergies or sensitive skin. Because these particles are nearly invisible, you may not realize they’ve circulated through your space until irritation begins. Removing them often requires professional cleaning or, in severe cases, replacing household items.
Do All Mattresses Have Fiberglass?
Thankfully, no — but many still do, especially in lower-cost or mass-produced models. Fiberglass is an inexpensive way for some manufacturers to meet flammability standards, which is why it often appears in mattresses that prioritize price over long-term quality.
The good news is that more consumers are asking questions, and that’s driving brands to be more transparent about their materials. Before you buy, take a moment to review the construction details and verify whether fiberglass is listed. It’s one of the simplest ways to protect your health, your home, and your investment.
If you’re comparing durability as part of your research, you may also want to understand how long a quality mattress should perform. Our blog post on how long mattresses last explains what affects lifespan — from material density and coil strength to overall build quality — so you can shop with confidence and choose a bed that’s made to hold up for years.
Benefits of Choosing a Fiberglass-Free Mattress
A fiberglass-free mattress gives you a cleaner, stronger foundation for better sleep. Every layer is built with purpose, using high-quality materials and solid construction instead of hidden fillers or shortcuts.
You’ll often find denser foams that resist sagging, supportive coil systems that keep their shape, and sturdy edges that help the mattress stay stable year after year. Those qualities translate to consistent comfort and reliable performance — especially for plus-size sleepers who need a bed that’s as resilient as it is comfortable.
A fiberglass-free mattress also supports a fresher sleep environment. Without fine glass fibers that can break down over time, there’s less particle buildup in the air and fewer irritants trapped in fabrics or surfaces. It’s a cleaner kind of comfort, one that lasts as long as the mattress itself.
And beyond the physical benefits, there’s reassurance in knowing exactly what’s inside your bed. Transparency matters, and when a brand is open about its materials, you can feel confident that your mattress is safe, durable, and designed to perform — that’s the Big Fig standard.
Why a Fiberglass-Free Mattress is Worth It
When you bring a mattress into your home, it becomes part of your daily life. You sit on it, sleep on it, and sometimes even work or read on it. That’s why it’s worth investing in mattresses without fiberglass — because every moment you spend on your bed should feel safe and supportive.
Fiberglass-free models are a smart choice for families, allergy sufferers, and anyone who values a healthy indoor environment. They’re easier to maintain and more resistant to breakdown, meaning you won’t have to worry about particles, odors, or hidden wear affecting your comfort over time.
