1. A mattress arrangement comprising:
a mattress base having a length, a width, and a top surface having a mattress base area defined by the mattress base length and the mattress base width, the mattress top surface including a mattress base top fabric, the mattress base having a bottom surface having the mattress base area and including a mattress base bottom fabric;
a mattress topper having a length, a width, a weight, and a bottom surface having a mattress topper area defined by the mattress topper length and the mattress topper width, the mattress topper bottom surface including a mattress topper bottom fabric, the mattress topper configured to be placed atop the mattress base in a use position so that the bottom surface of the mattress topper rests on the mattress base;
a first friction enhancing fabric permanently secured to the mattress base top surface; and
a second friction enhancing fabric permanently secured to the mattress topper bottom surface;
a third friction enhancing fabric permanently secured to the mattress base bottom surface;
wherein the first friction enhancing fabric, the second friction enhancing fabric, and the weight of the topper are configured to cooperate to frictionally oppose sliding of the mattress topper relative to the mattress base when a lateral force is applied to the mattress topper solely and without requiring additional fasteners connecting the mattress topper and the mattress base so that the mattress topper is not removable from the mattress base without at least partially lifting the mattress topper off the base;
wherein a duo of the first friction enhancing fabric and the second friction enhancing fabric define a higher coefficient of friction than a duo of the mattress base top fabric and the mattress topper bottom fabric;
wherein the third friction enhancing fabric, the second friction enhancing fabric, and the weight of the topper are configured to cooperate to frictionally oppose sliding of the mattress topper relative to the mattress base when a lateral force is applied to the mattress topper solely and without requiring additional fasteners connecting the mattress topper and the mattress base so that the mattress topper is not removable from the mattress base without at least partially lifting the mattress topper off the base;
wherein a duo of the third friction enhancing fabric and the second friction enhancing fabric define a higher coefficient of friction than a duo of the mattress base bottom fabric and the mattress topper bottom fabric; and
wherein the mattress base has a first firmness when in a first orientation with the top surface facing upward to contact the bottom surface of the mattress topper and a second firmness different from the first firmness when in a second orientation with the bottom surface facing upward to contact the bottom surface of the mattress topper.
