When something like memory foam or latex is mentioned as a component of the mattress, it is often the case that the material mentioned is only part of the mattress. The industry does have all natural 100% latex mattresses, but those mattresses average more than $5,000 retail. Make sure you ask the salesperson whether the mattress is made with natural or synthetic latex, and what percentage of it there is. A word to look for is Talalay. This is the name of the process of turning natural latex into a foam. Avoid “dunlop” which is a way of making latex foam from a combination of natural latex and other materials, most of which are based on petroleum. If you are looking for a mattress that is specifically designed to be better for the environment, I recommend looking into the Nature’s Rest brand. The latex mattresses at IKEA should fall under the $1000 mark, and Nature’s Rest should be at least $2000. In the spirit of full disclosure, I must let you know that I have not worked with Nature’s Rest, but I have worked with the Spring Air brand, whose manufacturer also makes Nature’s Rest. Spring Air has been in the business since before our grandparents were born, and I was very impressed with their non-latex product when I worked with them. Ikea, on the other hand, is a furniture retailer at the end of the day. I am always wary of furniture retailer’s in-store mattress brand (that is all IKEA offers) as it seems to me that they would make aesthetic or economic choices, rather than choices that would actually benefit their customers.
