So today we’re going to look at two specialty foams, natural latex and Memory Foam. Memory Foam is a specialized polyurethane foam which was developed in the 1960’s. The chemistry of making it is complex. It is formed by reacting a PolyAll and a isocyanate in the presence of a catalyst.
On the other hand, natural latex, like ours, is made from the sap of a rubber tree and is commonly referred to as 100% natural. [00:00:36] While both are foams, but they have totally different feels. We’re going to take a look at the differences by doing a few demonstrations.
The first demonstration is responsiveness. We’ll place a weight on each piece and we’re going to test the recovery rates of both materials. Once the weight is taken off, the latex returns to it’s original shape instantly, while Memory Foam has a longer recovery time. [00:01:00]
The next demonstration is support. When we place a weight on the Memory Foam, it has a low resilience and easily adjusts to the body’s contours. The weight is totally enveloped by the Memory Foam, whereas, when we place the weight on the latex, it conforms to the weight, but pushes it back up. When we drop a weight on the foams, you’ll see the Memory Foam absorbs the impact, but offers little support. But when we drop the weight on the latex, the natural resiliency of the latex springs back, offering more support. [00:01:30]
Now with motion transfer, you’ll see with our glass of water test. Both are very good at dampening motion. When you place the glass on Memory Foam, the water doesn’t tip over, just like latex.
Our last demonstration is edge support. When we place the weight on the edge of the latex, you’ll see it doesn’t roll off, allowing you to sleep closer to the edge. When we place the same weight on the Memory Foam, it rolls off instantly. Those few extra inches can be important when your dog or child come into bed with you.
So those are just a few demonstrations that highlight the difference between Memory Foam and latex. [00:02:04] If you have any other questions, feel free to give us a call, send us an email. We’re happy to help.
