Can you help me find a slip cover for horrid leathertte chair?

[blossombath]

We have a leathertte reclining chair, which is v comfy and useful for nursing (so don't want to get rid of it yet) but a bit nasty looking.

I saw something like this in a La Redoute catalogue but it's not available to buy in UK. Any ideas where I could get similar, and do you think it would work on on the armchair (I know it might not be exact fit, but close enough will do)....
