As Leon says, the screw should have full thread depth in the wood; we
don't know what size the screw is nor pilot hole was drilled so can't
comment on what might be the actual installed strength of the connection.

"Safe" depends on what the maximum working load is going to be as well
from a purely practical standpoint without consideration of any
code-like rules...

And let's not even speak to the load capacity of the cord, the canvas
(?) seating, the weight of the occupant, the. .

Person I used to know made slings for people who engage in
"alternative lifestyles". His general rule was that if it wouldn't
hold a Hemi, it wasn't strong enough (yes, he had a large Chrysler
engine that he used as a test article).


Some people weigh more than a typical V* engine.
