The Story Behind This Sofa
Not all leather is the same, and the differences are worth understanding before you spend this kind of money.
Full grain is the outermost layer of the hide with its natural surface intact - the strongest, the most breathable, and the only kind that develops a genuine patina over years. Top grain has that surface lightly sanded and corrected to remove blemishes, making it more uniform but slightly less durable. Split or bonded leather comes from the lower layers or from reconstituted fibre, and it is the material that cracks and peels within a few years - which is what most people are actually remembering when they say leather does not last.
Upholstering leather is also a different craft from fabric. Hide comes in irregular shapes with natural variation, so panels must be cut around imperfections and matched for tone across a sofa - a large set may need hides from the same batch. And leather cannot be eased and gathered the way cloth can, so every panel has to be cut precisely; there is no correcting it on the frame.
