Two 'Twin XL' toppers placed side by side form the same dimensions as a King mattress, so you can use them to customize both sides of a King to achieve each person's desired firmness. They would fit right up against each other and latex sticks to itself quite well so there's not usually an issue with them shifting at their "seam". They can be held together more securely on the mattress with a well fitting protector under the fitted sheet. Answer from Bill_K1 on reddit.com

can we stop pretending memory foam is some miracle? you’re basically paying $$$ for a swamp pad that hugs you to death. every dude in this sub is gonna say fam just get memory foam. yeah cool, if you enjoy marinating in your own body 💀 imo the stuff that actually works are cotton/down-alt toppers, gotta be breathable, washable, don’t turn your bed into a sauna fr. a lot of folks mention the sleep mantra cotton topper since it softens up firm beds without cooking you alive lol More on reddit.com

r/Mattress on Reddit: Is there such a thing as a one-sided mattress topper?
February 15, 2021 -
We are looking at a king. The debate in my household is plush vs. firm. I have been reading about how you can make a firmer mattress softer with a topper. If we go with the firm, can i purchase a king size topper to make one side more “plush”? I suppose i could buy a twin topper, but do they make such a thing in a one-sided king, so that it would fit snuggly and I would not have to worry too much about wrinkles/bunching or shifting? Thanks in advance.

I've never heard of a one sided topper -- but it would not be difficult to use a foam adhesive to glue two Twin XL toppers to each other.
