Most of the assets have been really useful, but the furniture is not 'up to modern day design expectations'. For example, the red leather task chair is a big 'no no'. I've seen a lot of raised eyebrows when people open the furniture part of the library
I would suggest browsing through some design websites to get some inspiration.
We'd also be happy to give you a long list of manufacturers that make great looking pieces. Brand likes Muuto etc.
Perhaps even better, before you commit resources to model pieces, ask input from the community by voting here. Or if that is not feasible, perhaps get a design consultant to advise on which pieces to model.
