Hybrids and innersprings might both have coil support layers, but they have very different feels. Hybrid mattresses always have a pocketed coil support core and at least two inches of either latex or memory foam in their comfort layer. Meanwhile, innerspring mattresses can have an open coil or pocket coil design and can feature other plush materials in their comfort layer, such as cotton, wool, fiberfill, or even down. If we had to give the edge to one mattress type, we’d have to go with the hybrid. Hybrids combine all the best features of foam beds with the best features of innerspring beds to create a mattress that’s cooling and responsive yet contouring with tons of pressure relief for stressed joints.
