Some companies cash in on the buzz around the word “latex” by pairing a synthetic blended latex (combining natural and petroleum-based latex, and who-knows-what chemical additives) with other relatively cheap materials like polyurethane foam, polyester, rayon, conventional cotton, etc.
Simply containing some latex does not necessarily make a mattress comfortable, natural or healthy – so ask a lot of questions and give it the 20 minute test ride before making a purchase. Watch out for companies that “green wash” by making broad health and environmental claims while “cutting corners” on the actual materials and construction of the products.
The current trend is to make health and environmental claims for products that contain polyurethane foam that contains 15-20% bio-based (e.g. soy or castor oil) ingredients, but which are still 80-85% petrochemicals and include flame retardants. From our perspective, this is like putting an organic lettuce leaf on a fast food burger and proclaiming it a “healthy eco-burger”.
Look for retailers that specialize in healthy mattresses.
