Land of Leather (if they still exist) would probably not be interested wishing to sell you a new recliner rather than supply a replacement part.
I don't know this chair but suspect the cable is a bit like a bicycle brake cable. If you can get the old one out of the chair and it is like a bicycle cable then take it to a good old fashioned cycle shop or a motorbike garage and see if they'll make one up for you - if they can't do it they'll probably know who can.
