I might have to take you up on that.I'd be happy to give you a tour anytime. Let me know.
I have four 4x8' cedar boxes and a little 3' octagon box I bought as kits in 2017. I added a 2X16' cedar box I built myself in 2018 (the one with the snap peas, among other stuff). So, this is the 8th season of soil contact on the cedar and all the boxes are in pretty bad shape now. I'm holding them together with stakes on the sides and hardware cloth in some of the worst places. Some cedar planks have completely rotted and soil is leaking out at the corners in most of the boxes.
So, if I had it to do over, I'd go with a corrugated metal design. Something like @olegbabich posted looks good: corrugated metal boxes. Boxes can be built with longer lasting pressure treated 2x3 or 2x4 frames so that only the corrugated metal touches soil (and the soil doesn't touch the wood). This is an ideal design for long lasting boxes.
If I try to squeeze another season out of the cedar boxes, my raised beds will be piles of dirt and rotted wood. So, I'm looking at designs on YouTube (there are lots) and plan to build the replacement boxes this fall.
My YouTube guy is James Prigioni - comin to you live from Jersey! He's got a bunch of different garden beds. This was the latest
I like the boxes he can rest a cheek on, with a 2x6 or 2x8 ledge.
