We really love this sofa. We just put it in the room we purchased it for, and it fits perfectly in a small room, and it's SOOOO LIGHT! Most sleep sofas weigh a ton. This one is light, easy to move and of high quality. We haven't yet used it for a guest to sleep on, but so far, we are very pleased with it. It also arrived much sooner than expected. We were told it would be 2-3 weeks to ship and we got it in less than 2 weeks. All good!
I've had this sofa for over 3 years. I bought it 'cause it's a sleeper yet only weighs 75 lbs which is great for me 'cause I move a lot! I find that as a sofa it holds up very well; there's been a lot of sitting and laying on it and it's still firm and comfortable. The bed is not so hot. The real problem for me is the middle section of the bed which is shorter in height than the others. This makes for a slump in the bed right where your back would be if you were sleeping on your back, which is quite uncomfortable and also bad for your back. If the middle section were the same height and thus even with the back and front sections I think it would be just fine. If you have room in your place for an eggcarton type mattress pad you can use it on top of the bed to mitigate the problem. The only other problem is with sheets not fitting on the bed; you need to use a top sheet and hope it doesn't move around too much in the night.
