I suppose one should make allowances when reviewing a product that is at the less expensive end of the market and, taking that into consideration, this is not a bad buy by any means.
As a bed it is very comfortable. As a sofa it is pretty so-so, mainly because if you lean on the backrest it gives way and you risk ending up on your back with your legs in the air. The secret is not to use the backrest.
But the main shortcoming is the weedy air pump - but again, it is built to a price. It takes a long time to inflate, making the pump feel very hot, but even longer to deflate for some reason. And it will never deflate sufficiently to get it folded and back into the carry bag the way it came out.
Still - as a bed and an occasional 'sofa-bench' it does its job.
