Is there any cushioning that is resistant to sweat?

It's exactly as the title says~ Is there a cushion that is resistant to sweat?

It started raining overnight yesterday and continued raining all night until dawn, and today it is cloudy all day. This muggy weather is tough.

I feel like I'm sweating more in this muggy weather.

I'm wondering if there is a cushion that holds up even when you sweat. I hear the rainy season is starting, and I dread the sticky, humid days. This too shall pass, right? Everyone, please take good care of your health in this sweltering weather.
