My wife asked if I could build a hanging/swinging bed next to our fire pit.

So I sunk two 12’ 6×6 PT about 42” down (hardpan), filled about halfway with concrete mix and back filled with the very clay/stone soil (see picture below). They are 9’ 3” apart outside edge.

I know, I know…I should have had a plan BEFORE sinking the posts.

I have a vision (albeit quite blurry) of a 2 post pergola type structure.

Possible putting a 6’ 6×6 across the tops of the vertical posts with 2×8 connecting them?

Maybe a knee brace (45 degree about 2’ out from the vertical post) to further support the 6’ 6×6?

Maybe an angle brace of some sort between the 2×8 pieces and the vertical post?

Then holes in the 6’ 6×6 to run cable or rope down to the bed platform?

Sure would appreciate any advice/help/suggestions.

Thank you!

At this point I think I’d put a 6X6 across the top BETWEEN the uprights. Then put 6×6’s as a “T” at the top of each one, just a bit shorter than whatever bed you’ll be hanging. Put supports on both sides like in the picture you posted. Then build the bed and hang with chains.

What were the diameter of the holes for the posts?

As a pergola structure/shade structure, there are no issues. However, once you attach a hanging bed attached at the ends of 3 or 4’ arms and put 300lbs on the bed (2 people), you have created a giant compound lever. I would be worried that the poles will not be stable and they are going to twist and rack. I would want to see a four post design or com type of angle bracing to the ground to prevent poles moving as the bed shifts/moves.

Putting a 6×6 across the posts makes a lot of sense—much more stability.

I wonder if entirely doing away with the “T” at the top will improve the stability also.

The holes were made with a mini-excavator, so they are about 22-28” diameter. 5, 80lbs bags of concrete in each.

I drew these up in Sketchup (I’m a beginner at both Sketchup and woodworking).
