Refresh your mattress with this dual chamber mattress topper with a plush 3-inch gusset for loft and comfort. The bottom chamber is filled with nano feathers, in which the feathers run through a process that removes the pesky quills from feathers to provide a poke free, down-like feel. The upper chamber is filled with a layer of polyester to provide an extra layer of comfort. The 233-thread count fabric one the face of the topper offers a soft, breathable feel and the down-proof polyester bottom keeps the nano feathers in place.
