If you have a garden where you have to follow the sun round throughout the day

[Rainbowshit]

How many seating areas and sets of furniture do you have? Or do you move the furniture with you?

I think we could do with three but worried it'll look ridiculous.

How big is your garden? Ours is about 80ft and south facing but narrow so we have a main seating area at the back of the house which gets sun for most of the day and a bench at the end of the garden to catch the last of the evening sun. Three would be overkill for us but might work for you.

I have a couple of designated areas with furniture that stays put (one area has a table and chairs and another area has a bench).

I also have some deck chairs and a little folding table that I can easily move if I want to.

Depending on the space you have, I'd think about using different areas for different things, which will minimise the 'duplicate furniture' effect. A table and chairs for eating meals al fresco in one spot, a bench for an evening G&T in another, a hammock for reading a book, a bistro set for breakfast or a cuppa... etc.
