Where should i put my subwoofer?

Hi.
Intro: I would like to say sorry for my mistakes, i hope you can understand me.. I am bad in english language.

So this is my room plan:


My problem is that my subwoofer sounds much better(the bass is like thumper(that means that bass is deeper...)) in spot "s2" then in spot "s1". But problem is that i always am in spot "s1", but sound in "s2" is better when i stand up.
So maybe you can recommend where should i put my subwoofer to get same sound(in spot "s2") in spot "s1"?
Thanks.

I would try the edge of the wall between the bin and the table facing the lower left corner toward where you sit and the edge of the room and see it that works.

I don't think we can really give you that answer because we can't hear it. Just keep moving it around until you find a spot you like. If you don't have carpet put a rug under it.

Low frequencies, as produced by a subwoofer, are omni-direction once they leave the enclosure.

Avoid corners, unless the port is facing the corner(for reflective waves). The longer the waves can travel until refection, the better.
