I think your beds are very nice. They look like they are going to last for a long time. I haven't found anyone around my area that gives pallets away. Thank you for the help.
I found a number of businesses that put out free pallets. Saves them money from paying to have them hauled off to the landfill and disposal fees on top of that. Anyways, the build is not specific to pallet wood per se. You could use salvaged wood, or new wood, to make the same design.
Over the years, I have tried a few different raised bed designs, and this pallet wood raised bed v 2.0 is my latest build with benefits of a stronger build and easier to put together. I don't expect free pallet wood will last forever, but the design makes it very easy to maintain and replace any boards that might rot out. Or, considering it costs me less than $2.00 for the screws and nails, I will just build a new one if/when the old raised bed needs to be replaced.
