Netherlands-based bERT&dENNIS (that's Bert van der Grift and Dennis van der Burch) strive for "Simplicity, fluidity, angularity, utility; organic forms vie with subtle references to Bauhaus, kitsch, traditional Japanese." Below is their new Fold lounge chair, followed by DotShop. Click here to see more of this Dutch dynamic duo's work.
Alan Heller's ergoErgo "combines the health benefits of an exercise ball with the comfort of a cushioned seat;" perching atop the constantly swaying stool forces you to engage your legs and back to stay upright. (Having used an exercise ball as my desk chair for approximately two years, I can see one clear advantage of the ergoErgo--it won't get thoroughly dirty like exercise balls do, since the only part of the ergoErgo that comes into contact with the floor is the bottom.)
