The new improved Dura-Beam Series version of the deluxe pillow rest raised bed offers ideal comfort and durability. The fiber-Tech Technology beams do not stretch over time, offering long lasting structural stability. The outer perimeter frame on the sleeping surface provides added edge support making the bed seem roomier and easier to get in and out of. The 16.5 (42cm) raised height provides easy accessibility and a closer feel to traditional mattresses, making it the perfect choice for house guests, dorm rooms and even camping trips.
