Chair for the study desk unit for my son #2: day 3, attaching seat to the legs

Now I am already worried about using rustic logs for the chair… The logs are pretty much straight, I thought. But actually not, not at all. So for the 2 legs, the point where they attach the seat are not the same. The right one will be about 15 mm forward.

But I started, and that was the original idea…

Mortise and tenon are different from what I usually do, but it’s got to be good and tight one, need to make it strong. For mortises, it was an easy part. Just cut squares out from the seat. Made them 20 mm width.
Then I drew a line 460 mm away from a side on my workbench (which is the actual hight ofd the seat), then I put one leg fitting the bottom to the side. Then made straight slit with router using the line I drew, make it the same as the depth of the seat.

Didn’t have much time, so this is what I could have done on Day 3.
