The PlushBeds Orthopedic Foundation is made of sturdy, heat-treated spruce wood. The decision to go with spruce wood as well as choosing heat-treated wood as part of our latex mattress materials was a conscious effort on the part of PlushBeds in keeping with our commitment to green manufacturing processes and green mattresses to provide families with healthy choices in bedding.
The proper foundation for your mattress is an important choice, just as choosing the right mattress is. The foundation not only gives the mattress height, but it also (and more importantly) serves to support the foundation. Just as your body needs support while it sleeps, your mattress needs proper support in order to maintain its shape and extend its usefulness to you.
Heat treating is a process by which the mattress foundation is exposed to high temperatures and “fixed” to avoid the shrinking and swelling that often happens with wood. It’s a green process for preserving wood that produces far less toxicity in the wood than typical chemical treatment methods.
It does more than preserve wood from swelling and shrinking with moisture and other issues. It also prevents the wood from rotting. That is a result of the conversion of sugar within the wood into an unusable form so that fungi known for causing rot cannot grow on the wood as easily.
Another way heat-treating wood prevents rot is by distributing the wood’s natural protection capabilities throughout the wood while it’s being heated.
In some instances, heat treating also changes physical properties of wood including its stability, durability, and mechanical properties. From a wood preservation perspective, heat-treated wood lasts longer without damaging the planet or bringing unnecessary and potentially harmful chemical wood treatments into the home.
Wood cannot be certified as heat treated wood by the International Standards for Phytosanitary Measures 15 (ISPM 15) unless it has been heated to 133 degrees F for a minimum of 30 minutes. The combination of temperature and time is necessary to destroy any pests that may be residing in the wood. Depending on the intended use, though, the temperature requirements may be higher.
In furniture, for instance, the preserving process may require temperatures of up to 392 degrees F for as many as 24 hours. Heat treating wood at higher temperatures for longer periods of time is closely associated with quality. Wood used in construction, for example, would be heat-treated longer than wood used for packing crates.
At PlushBeds, our Orthopedic Foundation is made of sturdy spruce that has been heat treated, not chemically treated. It is then covered with heavy duty cotton fabric and paired with your choice of one of our latex or memory foam mattresses so you can enjoy many years of high-quality sleep with superior support from both your foundation and your mattress.
