While we recognize the brilliance of Jasper Morrison's Crate Series, we also recognize that the price tags are ridiculous. That's why we were super-excited to see IKEA's addition of a plain pine box to their IVAR series of simple storage...
Perhaps the images of Jasper Morrison's Crate for Established & Sons will help inspire you?
IKEA's solid wood IVAR box is untreated wood. It is ready to be painted, waxed or stained (or left alone). It can be cut, screwed into, or added onto (maybe casters?).
Solid pine sides with pine plywood bottom, the box measures 30.75 " wide, 19.25" deep and 11.75" tall. An IVAR pine box will set you back just $35.
