Seriously, I like Stokke, and I like the Hippo. And it's totally their call if they decide not to produce or carry it anymore. ergo:design in Germany picked it up, and it still rocks.
But Wolfgang Rebentisch, the man who designed the Hippo in 1993--or at least who won a bunch of design awards for it in 1993, including a Best In Show at the Nurenburg Furniture Expo, which, oddly, included 800 Marks and an all-expenses-paid trip to Paris to meet Philippe Starck--really deserves to be known for more than inadvertently saving Bugaboo from giving its double stroller an even more off-the-wall name 17 years later.
