While adults park their butts in $700 Aeron chairs, kids still sprawl and slump and fidget and dangle their way through the day in school furniture designed to meet or beat a $40 price point.

For school districts with deep pockets, there are choices — a tricked-out Node chair from IDEO and Steelcase can be had for $599."
