We moved from furnished rental to an empty house and our new sofa was a few months in the making. I found this product and bought it...
We've been using it for 2 weeks now with another 2 to go, it is comfortable enough to not make us dread the coming days. I had to inflate it two times in the 2 weeks, but it could be I couldn't close the vents tight enough.
The only point that might need some caution is when you open it as a bed it becomes a single layer and it feels like an inflatable sea mattress, not great for multiple consecutive nights of sleep in my opinion. At least for an average weight adult. Kids will not cause it to flatten when it is in bed mode.
