Pu or Fabric ?

[Vogon]

Hi guys, looking to get a comfortable and supportive chair for gaming and general pc use.
I am a larger guy, at 1.88m and 141kg with a 112cm waist and when gaming in warm weather I do get sweaty.
I thought fabric might be better, but as many are manmade, maybe its no different to PU ?
I have my eye on a chair I won't mention as OC don't sell them unfortunately, but any recommendations for a budget of £300 ?

The only downside with fabric is absortion and cleaning, I don't know if either will benefit "operator temperature", but at least the pu is easy clean
I asked the supplier about the fabric material, but the answer doesnt help much, "cotton based fabric" could mean anything !
