A Table That Changes Gears It took 10 years, but the London designer Christopher Duffy thinks he finally got his MK1 Transforming Table right. "I was trying to design a simple coffee table but I wanted to make it more clever," Mr. Duffy said. Every part now does something: The sides come up and become the dining table top, the tucked-away legs extend, and we designed it so they don't need to be locked. It's a perfect machine. The handmade tables are available in two sizes and in oak, ash, walnut or steel. A plywood version (which will pack flat for easier shipping) is to be introduced soon. Finishes can be customized - Mr. Duffy offers powder-coating in various colors - but size cannot. "Every little millimeter has been worked out," he said. Prices start at about $1,300.
