Wolf Corporation's Truck Eurotop mattress is a 9" thick 39" x 80" innerspring mattress that is designed and engineered using layers of natural cotton, CertiPUR fire retardant foam, a unique heaty sta-rite cotton inner quilt, and a 6", 288 high profile innerspring unit. Wolf's combination of steel coils, foam and our own fibler cotton blend provides one with a unique balance of comfort and support that offers one a feel that conforms to your body and breathes better than most Truck mattresses available today. Meets both MVS 302 and CRF 1633 fire standards. This Truck Eurotop mattress is compressed, rolled and boxed for easy shipping and installation. Proud to say Made in USA by Wolf Corporation, one of the oldest mattress manufacturers in the USA under continuous family ownership!
