According to my wife good furniture that fits your unique style and taste is hard to find. The Italian designed Modi Sofa may make things easier. Sort of like Lego, it allows for nearly infinite customization, using modules which you insert in the base to form different shapes and styles of sofas.
There are flat modules, back or arm rest modules, corner pieces, etc. They all fit neatly into the grid base. Finally, you can make your sofa how you want it. They even have a glass top to make an end table or coffee table if you like. Pretty neat. All furniture should be modular.
