Hi Natalie
I'm not sure if this info will be of help, as Land of Leather isn't one of the two companies we had info on re the problems leather furniture has had with some people.
Argos stores and a company called Warmsley's (branches throughout UK) both sold suites imported from China. The supplier was a company called Linkwise. It might be worth checking where Land of Leather have their suites made and who the supplier is. They may well have several suppliers, but as with most big companies, no matter how much you as a customer might pay, they get it made as cheaply as possible. Their buyers drive a hard deal with suppliers, who may in turn look to cut corners or use "inappropriate materials or methods" in its construction. Not sure IO can be of any more help, but would love to know if you get any success. Hope you and y7our husband can eventually sit back and enjoy your furniture. It you are successful, and do get some redress, and perhaps even a refund if the goods are "not fit for purpose etc", you might take a look at the Furniture Village company, nearest store to you is possibly Solihull - but worth the trip I'd say. Or check out a smaller retailer locally that is part of a buying group called AIS. I can give you more info on this if you need it.
Best wishes
