My husband moves a lot and keeps me awake, how can I solve it!

I have a Sealy Superking divan bed with a Posturpaedic Ultra luxury Supreme mattress, which is nice and soft.

The problem is that my husband who is much heavier than me (18st against my 10 st) moves around a lot in the night which can keep me awake.

I have been looking online at the zip & link mattresses.

Can you advise me if this would work with our divan base which is 7 years old.

We both like a soft to medium mattress.

Thanks.

Anne.
