Adding a Daybed/Bench to my deck

Hello Everyone, 1st post here….

So I recently added on to my deck and I’d like to add a daybed/bench for some seating and relaxation. The question is if it would be okay to mount the daybed/bench support to the outside of the beams. My deck is sitting on 2 pier blocks on that side of the deck and I used 2×10’s for the beams. I was planning on using 4×4’s as the main support for the daybed and using carriage bolts to secure the posts to the beam. I’ve included a picture for a little visual support.

The red lines would represent where the posts would be and attached.

I’m trying to avoid burying the posts into the ground with concrete, I like the look of them being attached to the deck.

I’m sure I left out some important info, ask away and thanks in advance!

Oh…and if anyone knows of any cool design plans for a daybed on a deck I’d appreciate that as well.

Thanks!
