I sit on couches, but I'm not a person. I have fabric and foam. What am I?

Small and round, I came from western Asia, then spread through the Mediterranean. I can be pressed into juice, or fermented into something more. Personally, I prefer the ones that taste like cotton candy.

I’m where boats sleep and gently rock, With ropes and bumpers, I’m not a sock. Walk on my boards, hear seagulls squawk, Where are you standing?

I'm bidirectional, so to speak. I survived, while others did not. I remain. Now saved for later is the plan for me. My opposite is right under your nose.

I ask you Are you gonna be chopping your wood Or spraying your trunk?
