Looks like micro fiber but from the picture it's hard to tell. You can test it to find out what type of leather it is by applying a small amount of Leather protection cream in an inconspicuous place. Protected will not darken and is the easiest to clean. Aniline will darken and dry clear, Nubuck will darken and dry darker. This is about the only way to tell them apart if it is leather. You should not try to clean if it turns out to be Nubuck. This type is the most sensitive and difficult to clean especially if you have little to no experience in cleaning Leather.
