The Side Cube Deluxe is a rectangular side-sleeper pillow from Pillow Cube, sized 28 by 14 by 5 inches to fill the gap under the neck and shoulder that side sleepers leave on a standard pillow. Its AeroPluff foam core has ventilation holes and air canals, and the removable stretchy cover is machine washable. It is larger than the original Side Cube, so it suits bigger frames and broader shoulders better than the standard model. Owners rate it well overall, though some find the foam too firm or too tall for their frame.
