We have the Froli system. I was unhappy when I realized the couch would not stay in the pulled forward mode because the Froli increased the height of the mattress. This summer we removed the first row of the Froli, the row that is under our heads, this allowed us to push the mattress down enough when we wanted to pull the couch forward. My husband and I are both short, less than 5ft 5in so this may not work for everyone. We did not notice any difference in how comfortable our heads were during sleeping.
