I first heard about Edgar Blazona when he released the incredibly affordable plans for his MD 100 modular dwelling. Since then he has released several other affordable DIY modern spaces and started up a furniture company True Modern that has simple modern affordable bedding and furniture. It looks like he is branching out and getting ready to do some lovely upholstered pieces like the sofa renderings shown here.
While they are not in production yet, based on other offerings from Blazona you can expect the couches to be relatively affordable and well constructed. He is planning three different style and having them available in 5 different colors. If they turn out anything like the renderings I have a feeling I'm going to love them.
