Ontwerpers Nu is a Netherlands company that creates really useful multifunctional furniture. They've got designs like the 'Bright Table,' which has a built-in 'bowl.' Although you can't eat directly out of the table because the dip is a little too deep, their website has ideas on it about what would work best for your space.
The 'Light Up' (shown in the gallery) is also useful. It's a chair with a built-in overhead light. No more scrounging around in your drawer to find that tiny book lamp -- just sit down!
