Our Everynight Road Deluxe is the economical semi-truck mattress, which provides a comfortable night's sleep while on a long haul. The heavy-duty nylon cover is designed to last longer than a traditional mattress cover, and offers an easy cleaning surface using mild soap and water. We have created the medium-firm foam to have the convenience of dual-sides, meaning either side may be used as the top for extended years of use! This truck mattress is made to fit semi-truck models.
