This "Tree" Stacking Cabinet by Landscape Products is designed to "grow" in height with you child. A stunning profile and colour palette for any room and for any age. I'd be a little terrified of stacking them more than two tall, though.
Bulego Writing Desk, designed by Abad Diseño, is set off by the scissor shape of its steel-&-wood legs. Materials for the desk structure & optional trays include wenge, oak, teak, or walnut, & an extensive range of lacquers.
