yeah the way its made, the metal support poles for the center are perfectly straight, and they are secured to the vinyl cover at the sides and they have a felt like material wrapped around the ends so that when it is all the way unrolled, the felt wrapped ends sit on the metal tracks and dont make any noise or squeeks. when you roll them up, the poles just roll right up with it. there are 2 straps that hold the rolled up cover from unraveling. while unfolded, there are no bows or lines indicating any support for the center but rest assured, they are there. this in my opinion is the perfect tonneau. its in about 1/2 inch above the rails and thats it.

 

I have the Lorado roll-up cover that is made by the same company as the Vanish roll-up. I had a decent amount of snow on it last winter and it holds up well. It is very easy for one person to roll-up and roll back out. It is also very well made. I would recommend it to anyone.
