Summer Side vs Winter Side
On some two-sided mattresses the winter side uses wool or a thicker, warmer quilted fabric, while the summer side uses cotton, bamboo or a cooling fabric; labels and stitching usually mark the side. Our 4 seasons mattress aims for the same comfort all year without flipping, thanks to its breathable build and washable top.
