I love it.  The one I bought, color Marmont Mocha, is almost like the softest corduroy, but nicer.  It also has piping which not all colors appear to have.  I love that it stays in place!  I've always had problems with futon mattresses, even if they are a nice thick coil, slip down and you constantly have to re-adjust.  This one basically snaps into place and stays.  The only downside to that is it's not reversible, but, like I said, it's worth it.
