Weve had three guests use this couch and they love it. I ordered a twin 3 inch memory foam topper and keep the topper and couch mattress flat in a plastic bag under my queen bed. I think its helping to keep the couch mattress flat and not scrunched up inside the couch itself. Were very happy with our couch. The pillows are too large for the sleeper sofa but look great on our other couches!
