Dual firmness mattress?

[WildFlowerBees]

Does anyone have a mattress where your side differs to your partners?

Dh wants something firmer, I prefer medium. I see that silent night now do a yours and mine but can't find any reviews.

Relyon and Milbrook also do them

I got one years ago but ended up returning it after a month. I suppose it depends how you and your partner sleep. If you both sleep on your own sides of the bed and never meet in the middle then it makes sense. But if either of you stray to the middle it is horrible. I had the firmer side and I would roll down the slope to his softer side in my sleep. Uncomfortable at the join.
