The Marlowe sleigh bed by Restoration Hardware Kids would be a wonderful toddler bed. The proportions would really lend themselves to miniaturization. But it only comes in twin and full size ($999- 1199). There is also a crib that converts to a toddler bed, but both ends are enclosed ($999).

I also love the look of the plain white cotton sheets against the dark wood. It is a look that could be copied with a less expensive bed, and make a room look like a million dollars.
