OK, let's get this out of the way: this futon has seen better days. It's gotten a lot of use over 4 years, and it shows. The fabric needs some cleaning. There are a couple of soft dips in it where the springs in the bottom have popped out. Said springs have also ripped through the fabric lining in the bottom.
However, it is somehow still comfortable. It still clicks into three positions: upright, flat, and halfway in between. Your guests will sleep on it comfortably—I still do sometimes.
