Stacking bed by the Swiss design-legend Andreas Christen produced by H.P. Spengler in 1960.It is a stacking bed, which was produced as a single and/or double bed. The bed mainly came in the colors white and black, also in the color red, which is quiet rare.  And as far as I know of, only on in green. The unique about this bed is, that it was the first fiberglassproduct, that was that big and was able to hold the weight of a full grown adult. No one before Christen created an object that size.

New edition of the bed is still available at http://www.scobalit.ch/de/index.php
