It could be PU Leather ie it is just polyurethane and no leather at all or it could be bicast which is leather (usually just a thin poor quality leather) covered by polyurethane which is coloured and often textured to look like leather.
Bicast can seperate at the layers leaving a bubble like appearance, the PU can crack over time leaving a craze like pattern. It can like any synthetic tend to gas out so leaves a chemically smell in the room until it no longer leaches the chemicals out.
I have not come across the name before and it could just be vinyl (PVC).
The bottom line is it appears to be a synthetic, not leather. If it is a variation on what is called ‘PU (bonded) leather’ that is worse than a synthetic in my experience.
You apparently put a deposit on a synthetic product and can chose to keep your order or ask for a refund since you stated you referred to it as leather to the sales person, and if the sales person did not correct you that would be misrepresentation as a reasonable person would have accepted that as implicitly confirming it was leather.
I hope this is helpful. Please let us know how you go.
