How to Identify Leather Type in a Showroom
The smell test: full-grain and top-grain leather have a faint natural, warm smell. Split-grain and bonded leather have a plastic or chemical smell, strongest near the underside of cushions. The bend test: fold a small section of the leather. Full-grain shows natural wrinkle lines consistent with skin. Bonded and PU leather show unnatural regular cracking patterns at the fold. The water test: one drop on full-grain absorbs within 10–15 seconds. On PU and split-grain with heavy coating, the water beads indefinitely. The reverse test: look at the reverse side of the leather. Full-grain and top-grain show a fibrous, suede-like reverse. Bonded leather shows a fabric or paper backing.
