Where to get heavy duty plastic seat covers?

I need heavy duty plastic seat covers for my 2002 Tundra with a bench seat. The old covers are tearing after 20 years of use. Don't know where the originals came from but I can't find any anywhere. Any ideas?

 

I don’t about heavy duty plastic but I’ve heard great things about the coverking rhino hide ones and katskinz

 

Is it the original covering that is tearing, or an old aftermarket cover?
If it’s cloth and you don’t care much about the aesthetics, you can use iron on patches.
They won’t last forever, but I did that in my T100 on the cloth bench seat and it worked pretty well for many years.

 

I have Coverking Rhinohides. They are decent. I would only ever buy them on sale though. Regular price is too much for what they are.

 

I haven't seen any plastic covers, I won't ask why you need them out of fear

 

shooooot do they do like black friday or whatever?
