A rather simple idea, with the Caspar adjustable table for kids by Perludi growing as your child grows.
A sharp design in its own right, this birch wood desk has legs that can be easily adjusted as your child gets bigger/older. You can also slant the desk for drawing if you prefer too. All in all, a desk for the long haul.
Just as well really, as even in discounted form, the desk is 380 Euros.
