We ordered two of these leather sofas to replace fabric sofas in the study. They are bonded leather but they have a high end look and feel and are very comfortable! The back section fits into the seat with two metal slides. The pillows are attached which I like.The nail head detailing gives it the feel of nice leather(not bonded) sofas we have owned in the past that cost much, MUCH more. The tale tale sign that makes me feel they are not actually more expensive is the 'wood trim" at the base - not terrible but not up to the quality of the rest of the piece. We shopped around for spfas like these and this is as good as it gets for this price.
