4x6 Version

I made a few modifications that I think people starting this project may want to know. 1. 4x4 box gets a little tight for more than one kid. I chose 4x6 so that the bench dimensions would scale up to 3 slats per section correctly, but the length of 1x4 boards would not have to be lengthened, which would required additional support. 2. As a rule of thumb, any outdoor lumber that may have prolonged exposure to water (IE. Touching the ground) should be pressure treated. I couldn't find 1" thick treated boards, so the box uses 2x10 boards. 3. Used a redwood semi-transparent stain.
