To make the next section a little easier to discuss, I will call the blend of natural latex and synthetic latex, Syntex. Syntex is another form of foam used in mattresses and toppers and is passed off simply as “latex foam”. Syntex has the same properties of natural latex when it comes to support, firmness and quality, but it does excel in one two areas: consistency and life. nem cao su kim cuong The chemicals added during the manufacturing process allow for better dispersion, and thusly, better consistency throughout each individual piece of foam. This gives control over the feel and the density of the foam. These chemicals also cause a strong cell structure within the foam giving it increased durability and longer life without sacrificing comfort. On the downside these chemicals do irritate those sensitive to allergies and can leave a particular odor. Thankfully, the smell does fade over time.
A true organic latex mattress uses 100% natural latex with no blending of synthetic latex. This makes for a consistent, high quality latex. Also, an 100% organic cotton cover and/or quilted organic wool for enhanced comfort. This is important to insure the feel and performance of the mattress. Organic cotton and wool make for a breathable, antimicrobial fiber that is also eco friendly. Some of the popular leading brands are Talalay 100% Natural, using the Talalay process and Naturaluz, using the Dunlop process.
The Talalay process uses a 6 step procedure that includes compounding, whipping air into the foam, pouring the foam into a mold, pulling a vacuum, freezing, injecting CO2 gel into the foam, heating, de-molding, washing, drying, and lastly inspecting for quality and fabricating. Whew! Sounds like a lot doesn’t it. Well, some say this process makes for a more consistent cell structure. This also makes the latex less dense to allow more air dispersed into the product. This process however is fairly new so not enough time has passed to determine just how long these mattresses last. With that being said, The Talalay process is said to be the premium way that organic latex mattresses are processed today.
The Dunlop process is similar to the Talalay process with the exception that there is no vacuum or freezing, and the mold is filled all the way. This makes for a denser firmer mattress, but less consistency in cell structure. The Dunlop process has a long standing history however, dating back to the 50’s and is known to be very durable and stand the test of time. Deciding between the two is a personal choice. Both process make for a wonderful reliable organic mattress. The choice is yours.
