The Platinum is by far the most comfortable of all the pads we offer. It has a 2 in. base layer of medium soft natural latex rubber topped with 1.5 in. of Energex which gives you a 3.5 in. thick pad. This combination gives you an unmatched level of support and comfort. There is no other pad on the market with this combination of quality, support, and comfort. A two-sided cover allows the user to have two options of comfort. The latex side is a firmer; more supportive sleep experience. The Energex side is a more plush sleep experience.
