i Sleep Seven Koco Foam Double Bed Mattress 4 inch | Reversible Coir Mattress for Double Bed Size 72 x 48 x 4 inch Size:Double 72x48x4 inches   A mattress really matters. We spend around 1/3rds of our lives on a mattress, unless you are an insomniac, in which case, you should really consider investing in the perfect mattress that will give you a good night's sleep. We at Sleepsutraa, bring to you a comfortable mattress that combines the natural fibre of a Rubberised Coir mattress, with the body contorting ability of a Memory Foam mattress, all of it, at an affordable price. Rubberised Coir mattresses are manufactured by processing coconut coir fibre with latex solution. Rubberised Coir is a natural fibre & is relatively airier in design. Also, coir is a naturally hygroscopic material & hence it absorbs moisture from the air. Memory Foam Mattresses are sensitive to body temperature & molds itself to support all your body contours. Memory Foam redistributes body weight & provides support to your neck, back, shoulders, knees, & legs. Memory Foam improves circulation & reduces spinal pressure.
