Wider chair alternative to Vertagear SL4000 ?

[somewhatdamaged]

Hi

I sit around 16 stone with quite big thighs from years of squats / gym

The above chair is what i have currently, and it's far, far too narrow

My thighs go past the edge of the seat, and i end up with bruises on the side of my thighs

(God knows how small you have to be to fit into it!)

Is there an alternative gaming chair that would suit me better? It's getting pretty uncomfortable when gaming for hours

thanks
