Help with bed sheet measurements

[mywifeandkids]

So I've ordered one of those adjustable beds, hoping it will help my awful back pain 🤞
It's two single mattresses which togther make a super king, the mattresses are 3ft across each. What size bed sheet would I need for these ?

Surely you buy two single mattress sheets?

If they zip up/join together, then presumably a superking.

Well I thought that but there is 2.5ft singles and 3ft ones and I'm not sure what measurements are for the 3ft. Sorry I'm probably being thick, autistic and numbers make my head go blank

Have a look on the website you ordered the bed from.

It should have dimensions on it, including mattress depth.

If the measurement has 2.5/3ft in it then it will be the measurement pre individual mattress, but otherwise it should be the total width/size.

That should give you a start point 👍🏻
