I did mine this time last year, and purchased pressure treated 2x4's. They have held up great. No need to treat them w/ sealer. MUCH cheaper than cedar. I go them @ Lowes and they also had the marine grade carpet as well. Better quality and less expensive that the pre-cut Bunk Carpet offered @ Cabela's and BassPro.Good Luck!!!
