The first thing any kid needs in order to do her homework is a great desk, of course. (No, lying on the bed with a laptop and textbook won't do.) For the low-maintenance kid who pretty much just needs a flat space to do work, with minimal storage, this understated desk is a great option. Bonus: When your kid moves out, you can use the desk for your own purposes. It's that sophisticated.
