Have you visited a traditional furniture store lately? If not, let me tell you what has been going on for the past few years. Furniture is getting ridiculously gigantic. Tables that don't fit in the average eat-in kitchen, dining chairs heavier than full-grown St. Bernards, sofas as big as Buicks, headboards that dwarf 8' ceilings. An article in The Columbus Dispatch published earlier this year suggests this trend to the Brobdingnagian is the fault of the McMansion. Makes sense. All that space needs to be filled. Which, when you think about it, seems counterproductive. I mean, huge furniture takes up space (aka square footage) which diminishes the navigable space in a home.
If we approach this as a chicken or egg question, I'm guessing the McMansion came first and retailers responded in kind. Now even those of us who don't live in McMansions are stuck with it.
