***BEST SELLER*** Enjoy the slow response foam as you sink down with absolutely no pressure points, making for a blissful night’s rest. The Polo Club Dr is the softest of the Latex/Gel Hybrid series, and is made with a proprietary plant based EcoGel, which is made from renewable soybean and castor bean oil extracts. Regenerative Celliant fiber between the Gel and Latex will help increase your oxygen level while you sleep. Supporting the gel is a Firm All Natural Latex support core. Latex is naturally ventilated, which allows for the mattress to breathe, and is far superior to the generic base foam used in most memory foam mattresses today.
