Desk to tall or Chair to short? Mouse Movement Friction

[Elite Knight]

I am currently having issue where my mouse seems to be getting to much friction on my mouse pad.

I use an

G903 Hero Wireless Logi

And a speedtype Mouse pad.

At some positions it seems less sticky as I say.

 

Haha my crude paint skills.

But this is mostly how I sit and thinking it is my position since at some angels the mouse seems fine. 

I sit with my arms and hands tad below the desk. So I think my chair it to small. And I sit with a slant foward where I should sit straight.
