You'll love the luxurious comfort of this mattress pad! Top-quilted rayon from bamboo blend fabric is silky to the touch and is extra plush for a more comfortable sleep. The rayon from bamboo fabric breathes extra well and can even help cool down those extra warm mattresses (perfect to counterbalance warm mattresses such as Tempurpedic). This is the highest-rated mattress pad on the market.
Top is 70% polyester/30% rayon from bamboo and is filled with plush, supportive synthetic cluster fiber.
Cluster fiber is a highly innovative polyester material that goes through an extra engineering process to create balls of fiber that "trap" air to allow the pad to keep its shape longer and allow more air flow than any other pad on the market. Backing is 50% cotton/50% polyester.
