Trev, Teak would be a great wood to use in your bed. The resistance to rot is great. The only problem I see is the 1/2 thickness of the boards. You have to cut the dado or grove for the metal strips to sit in. Those are in the 5/32" range. That would make the boards somewhat thin in that area. If you have any splintering or cracks in the boards in that area the board could fail. As strong as Teak is you would probably get away with using 1/2" boards. Also, the angle strips on the sides of the bed, are they already secured to the bed sides. Mine were, 1/2 boards would have left a small opening as the height of these strips were for 3/4" boards. Hope this helps! Frank
