Upgrade your sleep quality with our King Size Plush Mattress Topper. Its outer cover is woven of 40% viscose made from bamboo and 60% polyester, delivering outstanding cooling performance and great moisture‑wicking ability for cozy rest. Important material clarification: this blended fabric is only for the outer cover, while the inner filling is high‑density polyester, which creates soft pillow‑top cushioning to reduce pressure points and soothe back discomfort. Designed with 8‑21 inch deep pocket, the stretchable skirt firmly wraps your mattress to prevent shifting. Ideal bedroom bedding for improved comfort without replacing your mattress.
