Hi Bren, a few years ago IKEA had a super special offer on pinewood chests, there was a total run for them, I managed to get two of them, wanted them for the kitchen, but never got around putting them together, they don't fit in our new kitchen and we also don't have any other place to put them, so there catching dust in the cellar. If you like you can have one of them (for free of course), I want to give the other one to a friend.
Not sure about the special hinges though, it wasn't a very pricey thing, so probably nothing special.
You can also try
Baby-Walz - they have a shop near Gänsemarkt in Hamburg (Caffamacherreihe).
Or check out websites of chains like Ikea or Dänisches Bettenlager and search for Spielzeugtruhe or Spielzeug-Truhe.
We bought a nice chest from Dänisches Bettenlager and I think they have a shop near you.
Another option:
Baby-Dorf Halstenbek GmbH
Gärtnerstraße 150
Telefon: (041 01) 47 99-0

It's easy to get to from Wedel, it's right next to the A23 junktion Halstenbek at the Wohnmeile Halstenbek, or you can drive via Schenefeld center (which might also be an option to have a look for a nice chest).
The Wohnmeile is generally a good idea, there's loads of furniture shops there (Schulenburg, Möbelkiste, Dänisches Bettenlager, Richter, SB-Philip...)
Just let me know if you want to have a look at the chest we have in the cellar.
