Hello Everybody. I’m interested in building an outdoor structure with a suspended bed-like platform, along the lines of this image floating around the internet:

I wonder if anyone could help me to identify the wood used in this picture, mainly the big columns and joists. I know that this piece needs a weatherly outdoor wood as well as something with enough strength to support a lot of weight. Any help is greatly appreciated.

I would say that’s nothing more than treated posts that are finished with a stain. Nothing fancy about that….which would be fine in your case. It would be economical…..

Agreed: pressured treated SYP with a deck stain.

Holy cow! 16 4×4 posts? You could probably put a bus on that swing and the posts would hold… :)

In my part of the world that would be western red cedar and it looks kind of like it but it would help to know where the photo was taken.

The grain on the nearest post definitely looks like SYP, but I have my doubts whether it’s pressure treated. Definitely can’t get rough sawn treated around here. It looks rough sawn and with a band mill.

Those big, oblong knots you see on the left usually scream pine to me.

You could use any construction grade lumber for that, if the posts are not sunk into the ground. If they are, then use pressure treated rated for ground contact.

Looks like 2- 6×12’s put together for each post. I’d say Douglas Fir

compare the width of the stone trim around the pond to the thickness of the beams. I’d say they look to be 4”.
that’s where I come up with 6x’s for the beams
