Help me identify this H&M chair/ottoman and the leather

First time posting here....hope I attached the files correctly. We found this chair/ottoman at an estate sale and we bought it as my husband loves how it sits, it is in really good shape, and it goes well with our current H&M sofa. I was interested as to the possible collection name and opinion on the type of leather. Last photo is the one color is most accurate.
Want to also thank Duane for providing such a great resource with the forum.
