Latex vs Polyurethane vs Springs
Have the leading brand name mattresses companies invented a new way to build a bed? In a word, no. They are working hard to provide more of the same: bigger beds that require different sheets, sometimes even different headboards. Yet still they are using the same spring construction, with more layers polyurethane foam. Sometimes they add a layer of latex. But in order to keep profits up, you will usually find lots of poly-foam going by the name super-soft foam, upholstery layer, extra plush pillow top
Polyurethane Foam
Polyurethane foam, or poly-foam, is a petroleum product designed to imitate latex derived from the rubber tree (foam rubber). It weighs about one fourth the weight of latex, and lasts about one fourth as long (3-5 years instead of 20 years for Talatech Latex). Poly-foam is like a sponge. Because of its open cell structure, every time you move on your bed you are sucking into the bed dust, moisture, old skin, pollens and whatever is in the air. Wool and latex don’t do this.
Springs
Innersprings do not have the issues that polyurethane foam does. They can be gauged to different firmnesses. Probably the best thing going for them are they are incredibly inexpensive compared to natural Talalay latex, but do not last as long without losing their ability to support.
The FloBeds Talalay Latex Mattress
Natural Talalay latex is naturally conforming and supportive. The FloBed invention allows you to change the firmness on either side of your 100% natural latex mattress anytime for the 20 year life of the mattress.
We don’t use any poly-foam for added plushness in our beds.  Instead, we use wool. Naturally better. Our covers are not as “fluffy” as the “high-profile” mattresses sold in many stores, just better.  Our covers unzip, so you can easily hang your mattress-top in the sun. We suggest sunning your mattress-top a couple of times a year. Sunning will kill dust mites. Latex is dust mite resistant. If you suffer from severe allergies, with the top off, you can vacuum your mattress components to remove allergens. That, combined with your sunned mattress top will provide you with the cleanest and most comfortable mattress possible.
