Does Casper Mattress Have Fiberglass?

No, their mattresses don’t contain fiberglass!

Casper avoids using fire-retardant chemicals in their mattresses. That’s why the material has a silica sock.

Does Casper Mattress Have Fiberglass? The answer is no

Main Components Of Casper Mattress

Casper mattresses are made entirely of polyurethane foam. Its hybrid versions will include springs, latex foam, and polymer gel.

CertiPUR-US-certified foam and non-toxic adhesives are used to make the mattresses. Thus, you can rest assured that the Casper beds don’t contain formaldehyde and other potentially harmful compounds, including lead, mercury, ozone depleters, and heavy metals.

As mentioned, they employ silica in their mattresses rather than fiberglass. Under the cover of each mattress is a silica sock. The sock will melt whenever the mattress catches fire.

All materials in Casper mattresses are safe and have been certified to meet the US’s highest safety and quality requirements.

Are There Other Casper Products That Contain Fiberglass? 

No. All Casper products are meant for sensitive skin and are fiberglass-free.

Still, many mattress brands use fiberglass in their products. Some brands have fiberglass: Zinus, Olee Sleep, Lucid, etc.

Fiberglass is often used as a low-cost flame retardant. If your mattress catches fire, the substance will cause it to melt rather than burst into flames. 

Because of the barrier established by the melted particles, the spread of the fire is slowed and does not reach combustible items inside your mattress as rapidly.

In 2007, the Consumer Product Safety Commission established a flammability standard for mattresses. According to the Standard for the Flammability of Mattress Sets, mattress sets must meet the federal safety standard for open-flame fire resistance.

Mattress manufacturers frequently utilize fiberglass to meet these safety standards. It can be found in mattress foam and covers.

Is This Product Really Better Than The One With Fiberglass? 

Yes, of course. 

Fiberglass is a controversial ingredient in terms of safety. In fact, it has been proven unsafe for direct exposure. Thus, many high-end mattresses avoid using this material for their items.

Meanwhile, the silica in Casper mattresses is the least poisonous natural ingredient that will create any health difficulties.

About Casper Mattresses

Casper, founded in 2014, is one of the most popular bed-in-a-box manufacturers today. Original, Original Hybrid, Element Pro, Element, Wave Hybrid, and Nova Hybrid are the six lines of their mattresses. 

In addition to mattresses, the company sells pillows, bed frames, bedding, a dog bed, a weighted blanket, and many accessories, such as mattress toppers. 

Casper products have a 10-year warranty. The warranty is only available to original purchasers in the United States, excluding Canada and U.S. territories. It also applies only to mattresses purchased through Casper or one of its partner shops. 

The guarantee covers flaws in the mattress caused by manufacturing or normal use. It does not protect mattresses that were improperly installed or overused.

General Features

The Casper brand is chosen as the top mattress with high quality and satisfied customer experiences thanks to some highlights in the product lines, such as its motion isolation, pressure relief, edge support, and other features. 

Let’s explore these advantages in the information below!

Motion Isolation

Casper’s all-foam structure effectively isolates motion. Its two-layer system absorbs motion rather than distributing it across the bed’s surface. 

The polyfoam on the top layer provides a gently bouncy feel while decreasing motion transmission and the memory foam layer soaks in more motion.

This high level of motion isolation may lessen overnight disruptions when moving about on the mattress, which may be especially useful for sleepers who easily wake up frequently in the night.

Pressure Relief

Pressure points near the shoulders and hips are common among sleepers. Because these parts are often heavier and wider, they exert greater pressure on the mattress. If the bed lacks contouring, this might lead to pressure buildup.

The Casper products can conform closely to the body, aiding weight redistribution and pressure point relief. The third memory foam layer adds additional support around the core to keep the hips from sinking too far in. 

People with pains and aches may benefit from this mix of pressure relief.

The medium feel of the Casper may be suitable for people weighing less than 230 lbs. Most people in this weight range can sink sufficiently for comfortable contouring and balanced support. 

The Casper product may be too soft for sleepers weighing more than 230 lbs. If this foam overcompresses, they may feel extra pressure spots.

Temperature Control

The product traps less heat than other all-foam mattresses. The polyfoam layer on top circulates air, allowing heat to escape from our bodies.

To avoid sinkage, the comfort system’s second layer employs zoned memory foam that can be firmer in the center. This substance has a better breathable capacity than other high-density foams. While the 2-layer comfort system fits the body of the sleeper, it cannot trap heat as well as many rival products.

Edge Support

The majority of all-foam variants lack reinforced edges. 

If the sleeper approaches the bed’s perimeter, the foam compression may cause the edge of the bed to feel insecure, making it more difficult to sleep or sit near the perimeter.

The deeper support core of the Casper provides the edge with a sturdier feel than many all-foam mattresses. However, sleepers may still experience sagging if they sit or sleep toward the edge of the bed. 

Individuals weighing more than 230 lbs are more likely to sink than those weighing less.

Ease of Movement

The Casper is slightly more responsive than some other all-foam variants. This may make moving across the surface and changing positions easier at night.

When weight is removed from memory foam, it will respond slowly.

This might give the sensation of being “stuck in bed,” making it more challenging to change positions. The manufacturer addresses this issue with a top layer of polyfoam, which can spring back faster than regular foam. 

What Are Safety Concerns of Silica Casper Mattresses?

Although silica has been proven to be a better choice than fiberglass, people with sensitive respiratory systems or asthma may experience some nasal discomfort from this material.

The main issue with silica is its interaction with other chemicals utilized in the production of most foams used in mattresses. 

Polyurethane has become the main ingredient for many mattress manufacturers since the rise of the mattress-in-a-box trend. 


Does Casper mattress have fiberglass? No, this brand uses silica instead of fiberglass. 

Although it can reduce many health risks, you still need to take care of the mattress. An old and worn-out item can affect your respiratory system after a long time exposing directly to the mattress. 


Are Casper mattresses healthy?

Yes, it is. Casper mattresses’ foams are CertiPUR-US certified, which means they are free of dangerous chemicals, metals, and other materials. For example, the foams are free of ozone depleters, mercury, lead, formaldehyde, and other harmful chemicals.

How do I know if my mattress contains fiberglass?

The most common way is to read the mattress label. Look for a percentage of “fiberglass” as a stated material on your mattress label. The marking should also state explicitly that the cover should never be removed since doing so can result in fiberglass particles being liberated and exposed to the air.

Which mattresses do not have fiberglass?

Some brands that don’t use fiberglass in their products include Saatva, Puffy Lux, Amerisleep, Idle Sleep, etc.
