For small room, there's always the Ikea's Tromso loft bed and desk is only $220 (http://www.ikea.com/us/en/catalog/products/S59872897/). It' is not as elegant as the kickstarter bed but it is cheap and easy to assemble. The downside of ikea bed/desk is that when you invite your date/GF over for the first time, it is definitely not going to make any positive impression.
