H&M Executive Chair: Age? Made?

Attachment 6530 Attachment 6531 Attachment 6532 Attachment 6533 Attachment 6534

I just bought this H&M Executive Chair, and the seller didn't know any of the details. Does anyone know the approximate age or what the make and leather are? I can still smell the leather (it smells great)! I searched the H&M site and couldn't find this model. Also, I know it looks like there is a cut in the leather on the back, but that's just a mark in the hide.

I have no plans of selling it, but any idea what it's worth?
