My number one sofa buying tip:
Leather is not leather! You think you're getting cow (or similar) skin, but instead the leather have been treated with chemicals to make it expand, and then it's been been sliced into 10 pieces like wafer thin ham - or you get the off-cuts, which have been stuck in a machine and minced up with glue and then sprayed onto a sofa. You can look online about the naming standards for these 'leather' options.
Worst sofas I've ever bought were some 'leather' ones from Furniture Village. The 'leather' just fell off. I googled it and saw plenty of others with the same problem. Terrible company IMO.
Interesting. I pointed the OP to M&S or JL. Are their cheaper leather sofas also "leather" too?
