A pillow top mattress provides additional comfort by adding an extra layer of padding directly to the top of the mattress. This pillow-top layer is non-removable since it's stitched directly onto the top of the mattress. A pillowtop mattress is typically added to higher-end mattresses only since they will provide a softer and more luxurious comfort level. This can help side sleepers looking for a softer mattress that helps relieve pressure in the hips and shoulder areas. Check out our selection of plush and firm pillow top mattresses below.
