Sparkability is an online shop started in 2003 in an effort to make available “better things for babies and kids”. They carry a good selection of quality furniture as well as some toys, decor, and bedding. I found one line of items, made by InModern, that are especially Ponoko-esque: easy construction and made from solid birch plywood.
Prices on these items are all around $100. They’ve got lots of eco-cred and lifetime construction guarantees. See these designs and more at the Sparkability online store.
