You might be surprised to learn that a significant amount of engineering is involved when designing modern sofas. Particular attention needs to be paid towards the cushions themselves.
Not only should they be able to stand up to a significant amount of wear and tear, but other issues such as resistance to odours and moisture are just as important.
When we then take into account substances that offer a cost-effective edge, it is clear that numerous variables are analysed. What is the best type of foam to use within a typical sofa cushion and what benefits does it have to offer?
The Benefits of Polyurethane
Polyurethane is the most common substance found beneath modern sofa seat covers. There are two factors behind this observation:
Density refers to the physical amount of material within a given cubic foot or metre of foam. Compression is defined as the amount of force required to "squeeze" this volume by no less than 25 percent.
One of the pain reasons why polyurethane is often the preferred material arises from the fact that it can be engineered to accommodate various densities and compression rates.
This is important when dealing with different types of sofas; some customers prefer hard cushions while others are in the market for a more plush design.
The Cost-Effective Edge
Another reason why the majority of manufacturers prefer to employ polyurethane arises from the fact that it is one of the most cost-effective materials on the open market (it is a by-product of the petroleum industry).
Additionally, it offers a high return on investment thanks to its inherent longevity. Available in different grades, some variants of polyurethane foam can last for more than 15 years before needing to be replaced. This is an attractive quality to the average customer who does not wish to spend a great deal of money on repairs. So, there is indeed much more than initially meets the eye when referring to the internal workings of a sofa.
