What Are Memory Foams?
Memory foam is made from various polyurethane foam renowned for its unique properties. Like other foams, it compresses when subjected to pressure. However, what sets memory foam apart from regular polyurethane foams is the addition of specific chemicals that enhance its viscosity and elasticity, earning it the name “viscoelastic foam.”
When the pressure is applied, memory foam can stretch and conform to different shapes. Once the pressure on the latex foam is removed, it gradually returns to its original form. This distinctive quality enables memory foam to absorb energy and provide much-needed pressure relief.
Initially, memory foam was developed by NASA during the 1960s as a means to cushion against vibrations and potential crashes. Later on, the material found its application in preventing bedsores for patients who were immobile for extended periods. It was in the 1990s that Tempur-Pedic introduced the first memory foam mattress to the world.
Due to its responsiveness to body heat alone, memory foam easily conforms to the body’s contours, offering personalized relief and support. Additionally, memory foam effectively minimizes motion transfer between partners during sleep. Advancements in memory foam technology have resulted in newer generations of the material incorporating elements to reduce heat retention and promote more effortless movement atop the mattress.
What Is Memory Foam Made Of?
Memory foam comprises various ingredients, although the specific components may vary among manufacturers. However, all the flexible memory foam and polyurethane foams typically consist of a few fundamental elements:
Polyols: Polyols are organic compounds that contain multiple alcohol groups, known as hydroxyl groups. They serve as the building blocks for polyurethane foam and can be found in various products, including food, fibers, and other items.
Diisocyanates: These chemical compounds react with polymers to form polyurethane memory foam safe. Toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI) are the most commonly used diisocyanates in memory foam production.
Blowing agents: These agents aid in creating the chemical reaction that results in foam formation. Most contemporary companies use water as a blowing agent, which is less toxic than traditional chemical-based alternatives.
While many of the substances employed in memory foam compress manufacturing are derived from petroleum, some individuals express concerns regarding the potential toxicity associated with their memory foam mattresses.
What Makes Memory Foam Potentially Toxic?
The process of manufacturing memory foam involves the use of various substances that can potentially pose health risks. For instance, diisocyanates, which are chemical reactants utilized in the production of polyurethane foam, have the potential to cause respiratory irritation. Toluene diisocyanate (TDI), a commonly used reactant in memory foam production, is known to be a carcinogen and can lead to skin and respiratory problems. Moreover, certain blowing agents to make memory foam, including CFCs, can be harmful to inhale and adversely affect the environment.
Nevertheless, it is important to note that most of the chemicals used in mattress manufacturing, including TDI, primarily emit vapors during production. By the time the mattress reaches the consumer, the majority of these fumes have dissipated, leaving only trace amounts behind.
In recent years, the Federal Trade Commission has implemented specific criteria for labeling mattresses as non-toxic and environmentally friendly. According to these regulations, companies must provide reliable scientific evidence to support their claims of a product being non-toxic to humans or the environment.
Furthermore, the Environmental Protection Agency has banned using several blowing agents that were found to contribute to ozone layer depletion. Although not all mattress manufacturers utilized these particular chemicals, the regulations have encouraged companies that did to seek alternative blowing agents that are less harmful. Nowadays, manufacturers employ water-based or other approved blowing agents to achieve a distinctive form of memory foam.
Potentially Toxic Materials
Memory foam mattresses may contain the following chemicals:
- Methylbenzene: Methylbenzene, also known as toluene, manufacturers of memory foam mattresses utilize this solvent in producing polyurethane. However, it is crucial to note that inhalation of large quantities or rapid exposure to this chemical can lead to neurological damage, skin irritation, and respiratory issues.
- Formaldehyde: Formaldehyde substance, commonly used as an adhesive, can potentially cause respiratory problems, as well as irritation of the throat, eyes, and nose. However, it is unlikely to be found in recent mattress productions.
- Methylenedianiline: Often referred to as MDA, methylenedianiline is a component mixed with polyols to create polyurethane. Ingestion or inhalation of this substance may pose a potential carcinogenic risk.
- Methylene Chloride: Widely employed in various manufacturing processes, methylene chloride is a blowing agent and adhesive in the mattress industry. It is important to note that significant inhalation of this chemical can cause dizziness and nausea, and it is classified as a potential carcinogen.
While the abovementioned chemicals may appear concerning, it is essential to note that they are typically present at harmful levels during manufacturing. Furthermore, some of these substances are no longer utilized in mattress production due to regulations and restrictions. Many mattress companies have also shifted towards incorporating eco-friendly and organic materials.
Flame retardants play a vital role in ensuring the safety of mattresses sold in the United States, as mandated by the Consumer Product Safety Commission (CPSC). To comply with these regulations, mattress manufacturers utilize various materials to make their products resistant to fire. Some materials inherently possess fire protection qualities, while others incorporate chemicals.
In the past, polybrominated diphenyl ethers (PBDEs) were widely used to make memory, as flame retardants, despite their harmful effects on human health and the environment. However, after 2004, the use of PBDE compounds in foam was phased out, indicating that memory foam products manufactured after 2005 are unlikely to contain PBDEs.
Another commonly employed flame retardant is Boric acid, which is a familiar household cleaner. While not recognized as a human carcinogen, boric acid can cause skin and respiratory irritation and potential infertility. Melamine is another compound found in chemical flame retardants and utilized in certain laundry detergents and construction materials. Insufficient evidence suggests that melamine poses a cancer risk to humans.
While the CPSC oversees and regulates the use of flame-retardant chemicals in cheap foam mattresses, individuals who wish to avoid such substances can select non-toxic alternatives. For instance, many natural or organic mattress manufacturers incorporate layers of wool as a fireproof barrier. Additionally, one can opt for a mattress that incorporates silica-treated rayon or Kevlar, which are non-toxic and possess natural fire-retardant properties.
What Types of Memory Foam Products Are Potentially More Toxic?
Although many companies have made efforts to eliminate hazardous chemicals from the memory foam manufacturing process, some unscrupulous companies may still employ them to save costs. Be cautious of low-priced memory foam mattresses that seem too good to be true, as they are more likely to contain higher levels of harmful chemicals. Additionally, it’s essential to consider the potential presence of these chemicals when contemplating the purchase of a used new foam mattress, even if it is offered at a discounted price by a friend.
While it may require a higher initial investment, the best approach to avoid potentially toxic chemicals is to purchase from a reputable company that maintains transparency regarding its manufacturing practices. Look out for third-party certifications, inquire about the type of flame retardant used in the mattress, and prioritize mattresses manufactured in North America or Europe. These regions typically enforce stricter regulations concerning product safety.
