I am fantasy shopping a little, I only own cheap furniture (ikea/muji/made- maybe not mega cheap but definitely not ££££) so I probably could not bring myself to spend this!

My set up in my reception room is that we never had a sofa, we have a sofa dining bench and a Muji Dining table and chairs. We currently have this. My DH likes leather sofas but not the really bulky ones (which is why we opted for sofa benches which are slimmer). We think we have space for the 160cm 3 seater and the existing sofa bench would just be on the other side. We only have two extra chairs and those are usually tucked in on the left and right side of the table.

It seems crazy expensive to me, but then it is full leather... I hate PU leather! I don't need everything to be matchy matchy so it doesn't bother me having two different benches.
