Does the full set of deluxe carpets sold here require any double sided tape etc to hold down?

[Alan Andrews]

Hello,

I'm looking at and thinking about buying the full set of deluxe interior carpets sold here.

But do the carpets stay flat and hold themselves down or will I need double sided tape around the edges?

I've bought carpets before (not for my Ocean or from here) that have tended to curl up at the edges.

Any tips will be appreciated.

Many thanks
