I'm visiting the Jersey shore and staying in the world's tiniest house. Here, less is more, and the most important seat in the house is the one I'm planted on most of the day, writing. I needed more support for my back and, well, backside, and less area to support my notebook since I keep all of my clutter on my virtual desktop rather than scattered on my physical work surface.
The solution: The Dave (where do they come up with these names?) laptop table by Ikea ($25) and Seatflex task chair by Balt ($120, the best price I found from TigerDirect.com).
Dave looks like a lightweight, and he (?) is -- but thankfully the adjustable height allowed me to park one edge on the window sill to the right to augment its stability. The Seatflex chair (which I'm thinking of renaming Flo), provides weirdly floating-in-thin-air comfort and good positioning for mostly correct posture and keep-cool airflow (hence the likely renaming choice).
Got an interesting workstation combo -- especially for tiny places? Share, and we'll compare notes.
