Yes I would call it light canvas/ fairly heavy material, no haven’t loosened up at all. I could have put the back seat bottoms on better but I did it after knee replacement, still need to go back and fix it but isn’t bad or hard to put on
Living in the South I do not like neoprene seat covers , swamp ass
they are decent quality , lighter nylon material over seat backs but I have-not had any issues with them for the cost
My wife got me these seat covers in kryptek gray camo but they have all sorts of colors , fit decent have lasted a good 1.5 years with dogs and still look brand new , for the price could always try a set and test the look...

I have a Sport and added Rubi shocks , spring and 1 " spacer in front got almost 2 " of lift in front , still have .5 " of rake and have .75" spacer for rear if feel it needs it.
To answer your question no they are not needed. Good assumption is anything under 2" of lift and you will be fine...
So me and a friend started this conversation strictly around clearance and thought that 33's @ 25 psi vs 37's @15psi would have pretty close to the same ground clearance with same 2" lift on a trail or are we missing something?
