Questions about zip and link mattress

Hello Wondering if you can advise. My husband is a real fidgeter, so much so that we've been sleeping separately for the last few months (since our baby came along!). We both want to rectify this and are considering a zip and link bed. Would you recommend a particular one?

We tried a zip & link mattress but to be honest it was fairly cheap and didn't help. Our budget is up to £1,000. Any help much appreciated!

Thanks >
