This latex is 100% natural, made from the latex from rubber trees. It is slightly firmer than memory foam and has about the same firmness as medium-firmness foam. Has a rich and luxurious feel. Good for the top of the bed as a pad, or as the top layer of the mattress if you build your own bed. Additionally, some people like all latex beds and you can combine several layers of latex to build your mattress to your desired height.
