Here's my take on the Tryde Coffee Table. The only modification that I made was in the legs. Instead of untreated 4x4s, I used a 2x4, 1x4, 2x4 sandwich.
I also made the legs detachable for easy transport. This was done by drilling holes in the side piece and then screwing in these magic "screw/bolt" things [picture 5] into the leg. To assemble, I just pushed the legs through the holes, and then put a washer and nut on the bolts [picture 4].
