I found a nice light wood collection at Land of Nod. There is a Cargo Bed and matching dresser.
Cargo Kids Twin Bed (Natural) | The Land of Nod The pieces have the same modern vibe as that darling chair.
Land of Nod also has some pretty Jenny Lind beds in various colors, if you want a more eclectic look.
I might want a grayed green for the walls, especially if you use the natural wood colored furniture. You can pick out so many color possibilities from that chair! I'd use that pink for lots of accents. Have fun!
