Hackers Help: Do you know the name of this IKEA arm chair /single sofa from 1999?

anon1

I am trying for a while to find out what is the name of an arm chair/single sofa I bought in about 1999.  I searched online, in forums, Ikea fans etc, but could not find an answer. I am aware that arm chair is discontinued model but would like to try to find to buy on-line a new sofa-cover (would appreciate if you suggest what websites to look at for it?)

Could you please let me know the name of this arm chair/ single sofa model on photos?
