Choosing between Polyurethane Foam, Memory Foam and Latex Foam


Choosing between Polyurethane Foam, Memory Foam and Latex Foam

          Latex foam is a foam produced by vulcanizing liquid latex into a solid foam. The vulcanization process cross links latex particles with sulfur through the application of heat and accelerators such as zinc oxide.  Latex foam can be produced with natural latex, which is harvested from rubber trees or synthetic latex, which is produced from petrochemicals.  All of the latex foam we sell contains only natural latex and never contains any synthetic latex.  

          Latex foam provides exact pinpointed support and reacts instantly to your every move.  Latex foam does not “sink in” and “bottom out” as the night goes by.  It maintains constant support and does not get softer when warmer.  This makes it extremely easy to move throughout the night without any sleep interruption.  The pinpointed, contoured support allows certain areas of the body to sink further into the mattress while others are supported.  This is especially helpful to side sleepers, as they require more give in their shoulder and hip but more support in their midsection.

         Latex foam is one of the most durable types of foam available. Latex mattresses and mattress toppers long outlast those made with memory foam and polyurethane foam.  We often hear stories from customers that have had latex mattresses last over 20 years.  Latex foam scores highly on all foam durability tests which simulate long periods of use.     

 

        It is very common for natural latex foam to have emissions certifications.  All of the foam used in our Pure Green 100% natural latex mattresses and 100% natural latex toppers isecoInstitut and Oeko-tex class 1 (their most stringent class) certified.  While synthetic latex foam can sometimes have certifications, it is not as common.     

       We strongly believe that latex foam is, by far, the best type of foam to use in mattresses.  Latex foam offers several significant advantages over Polyurethane foam and Memory foam.  Because of this our products never contain any foam other than 100% natural latex foam.  Because we place such a high priority on selling high quality products at fair prices, you will find that our products do not actually cost much more than others made with much lower quality materials such as memory foam and polyurethane foam.

       Polyurethane foam, memory foam and latex foam are the three most common types of foam used in mattresses.  While latex foam has seen a bit of a resurgence in recent years, most mattresses only contain memory foam and polyurethane foam.  Interestingly, latex foam was very commonly used in mattresses prior to the introduction of polyurethane foam in the 1950’s.  

      We get a lot of questions about why we offer latex foam products but not offer polyurethane foam or memory foam products. We only sell latex foam products because we have a strong belief that latex foam is the best type of foam to use in mattresses and mattress toppers.  Latex foam offers several significant advantages over memory foam and polyurethane foam.
