Selecting a foam based on just softness is outdated. Modern manufacturers need to consider regulations surrounding comfort, durability, and safety. Daily use and safety compliance are critical for the materials used by furniture brands, automotive manufacturers, makers of healthcare equipment, and commercial interior design.
Flame-retardant (fr) foam is essential for safety design. Compared to conventional foam, FR foam decreases the risk and spread of flame. This makes it the preferred foam for use in safety-regulation-intensive, fire-risk foam applications for seating, transportation, and healthcare environments.
Flame-Retardant (fr) Foam Benefits
- Flame retardance
- Performance compliance with fire safety regulations
- Integrity of structure is maintained with foam use
- Foam is available in varying densities and firmness
- Reduced replacement costs due to improved durability
Prioritizing Safety Over Comfort Foam
There are different levels of importance when it comes to safety and comfort. Foam that has safety (in this case, fire safety) as a primary focus is referred to as flame-retardant foam. There are other applications, however, that focus on pressure relief and ergonomics. There is a need for these types of supportive materials in seating and mattress systems, as well as in various orthopedic products. These materials need to be able to adapt and contour to the body and also be able to recover.
Fire remains the most impactful safety concern globally. The World Health Organization (WHO) estimates that burns from fire cause 180,000 deaths annually and are the most extreme injuries l sustained in daily use environments.
When differentiating between safety-first and comfort-first foam, one has to consider the environment the product will be used in. Product safety will more likely address fire safety compliance if the product is a commercial product. On the other hand, if the product is a consumer sleep product, it will focus more on pressure relief and comfort. Manufacturers usually employ a combination of foam layers to address both concerns.
Things to Consider When Choosing Foam
- Fire safety standards
- Pressure relief
- Density
- Durability
- Temperature responsiveness
- Application-specific standards
If appropriate foam is chosen to begin with, manufacturers have less of a chance to face challenges related to performance and compliance later on. According to Fortune Business Insights, the flexible foam market will continue to grow over the next decade due to increases in demand from the furniture, bedding, automotive, and packaging industries.
When Memory Foam Sheets Might Be Best
Memory foam sheets have some unique benefits for applications prioritizing comfort. As opposed to standard foam, memory foam uses the heat and pressure applied to it to take the shape of the user. This characteristic helps it distribute force evenly across the surface and helps eliminate pressure build-up. This can come in handy when designing a mattress, cushion, or medical aid.
Popular Uses of Memory Foam Sheets
- Mattresses (and mattress toppers)
- Cushions in ergonomic office chairs
- Cushions in wheelchairs/medical chairs
- Inserts for car seats
- Orthopedic/medical supports
- High-end hotel bedding
Before settling on a memory foam sheet option, manufacturers must check a few critical features first to ensure they achieve their desired result.
What needs to be Checked First
- Density consistency
- Compression recovery
- Pressure-relief performance
- Surface finish quality
- Durability testing results
- How memory foam interacts with other foam layers
Conclusion
When considering various types of foam, the most important factors are safety, comfort, durability, and adherence to applicable regulations. When designers understand the advantages of the various types of foams, they are able to select the most appropriate foam technology for a given application.
