Top Wave 12"Soft waves ripple through the Top Wave 12", a 6. 75" x 6. 5" topper that prioritizes movement and texture over length extremes. This Jon Renau piece lands in the middle ground of the product line: the base is small enough for easy blending, the 12" length is accessible for many styles, and the pre textured wavy synthetic fiber requires minimal styling effort. At 2. 9 oz, it's lighter than many fuller toppers, making it comfortable for extended wear.
