This firm pillow has a 233 thread count and is available in two different sizes. This white pillow from Serta is made to provide ultimate comfort and neck support. The 55-percent Tencel / 45-percent cotton construction makes the pillow durable without sacrificing a cloud-like softness. Dimensions: Down and feather-filled products are packaged tightly during shipping. Upon receipt, remove this item from its packaging, fluff gently, and allow several hours for full loft recovery. In addition, products sealed in plastic packaging sometimes have a disagreeable scent because of concentrated natural fibers. A few hours of airing typically removes the odor.
