Cinderblock bench. This is my first and super easy bench. Placed the cinder blocks, measured the L-shapes, both inside and out, and attached them with Simpson Stong Ties in the bottom. Much heavier than expected!! Which means, this baby is ain't movin' :). Oh, the color is Ikea Varda brown. The floor is also from Ikea. Lesson learnt: not all 4x4s are the same size. It will be a little more expensive, but you are better off cutting each line from the same piece.
