ORGANIC COTTON STRETCH KNIT MATELASSE FABRIC
We love using only the finest materials in our mattresses, and that includes our fabric. After all, that's what you see and feel since it's the outermost layer of construction. There will be some manufacturers who say the fabric doesn't matter since you cover it with sheets. Well that may be true with a conventional spring mattress, but with a latex mattress the fabric really does make a difference.
Think of a fitted long sleeved button-up shirt made from stiff woven cotton. Now think of a fitted knit teeshirt that stretches and moves with your body. This is similar to mattress ticking (fabric) over latex. If the mattress fabric is quilted and covered with a woven material it will be more constricted, just like that button-up shirt. However, if you cover it with a quality stretch knit fabric, it allows the benefits of the latex to "give" and respond better to your body. Tight woven fabrics make the mattress firmer, while stretch knit fabrics provide the ability of the latex to do it's job.
CozyPure mattresses use a premium stretch knit matelasse made from GOTS-certified organic cotton and milled exclusively for us in the USA.
Because we deal directly with the mills we also know what they offer as "stock". Did you know that most so-called "organic cotton" fabrics advertised on mattresses are BLENDS of organic cotton and synthetic polyester yarns? Yes it's true! Most organic cotton knit fabrics feature only the top "face" as organic cotton, while the threads in the middle and back of fabric are 100% polyester.
IF THE FABRIC HAS A "SLICKNESS" THAT'S ALSO "SPONGY" IT'S USUALLY A SIGN OF POLYESTER
IT MAY SAY ORGANIC COTTON BUT THAT DOESN'T MEAN IT'S TRUE
MOST "ORGANIC" STRETCH KNIT FABRICS CONTAIN POLYESTER
Why is this so important? Adding synthetic polyester to the mattress, especially to the outer fabric, will conduct heat, and no one wants that because no one wants to sleep hot. It doesn't matter if there is wool in the mattress, if the outer fabric is not natural it won't disperse body heat properly. If any part of the mattress (inside or out) contains synthetic blends, there's a risk of heat retention (sleeping hot), moisture build-up (dust-mites), and possible off-gassing of chemicals (many of which are undisclosed and unregulated).
Remember to keep this in mind when selecting your mattress cover and linens, be sure to choose natural fibers. For instance, our mattress protector is actually made with the same exact fabric as our mattress. After washing it will get thicker (with a puckered texture) to help with surface stains and assist in protecting the actual fabric of your mattress. Since there is no polyester in our protector, it won't change the comfort. The same idea should be applied when choosing your sheets, make sure they're 100% cotton to keep that breathability throughout your sleep system. Don't add any synthetic polyesters which trap moisture and contribute to clammy, heat-induced sleeping.
