Recommended for people who like a firm, compact, energising mattress. The Latex Premium is a firm latex mattress. It promotes a robust and uplifted sleep posture. The pure wool in the quilted cover provides air circulation and disperses moisture for a dry, fresh sleep environment. The main support comes from the firm organic latex layer: a dense elastic foam refined from the sap of the rubber tree (Hevea brasiliensis). Latex is the ideal bed material – firm, supple and supportive – and 100% natural. The dense, firm latex we use in this mattress is extra resilient, and so will hold your body higher and firmer compared with other mattresses. Being pure latex it’s extremely durable: it will retain the same shape and density for well over 20 years. The organic cotton and bamboo quilted cover has quilted pockets full of 300gsm organic wool. Under the quilting wool is another 500gsm layer of organic wool that ensures air circulation while regulating sleep temperature. Loft: 130mm Latex:100mm high density firm 100mm core of firm density latex foam surrounded by 500gsm pure organic wool, encased in 300gsm pure wool quilted in organic cotton and bamboo blend cover. This latex mattress does not require turning because the latex and wool is durable. However, the quilted wool cover wraps all the way around, so this mattress can be flipped over (and turned head to foot).
