Best thing to stop rugs moving around on laminate flooring, without damaging floor?

[GuinevereWasHere]

What would you recommend for this?

I'm currently using Ikea Stopp Filt (the one that's grey and kind of sticky) and have read online that it can leave a residue on hard floors. Has anyone had this? Am now paranoid about it leaving an unremovable residue or somehow reacting with the floor and staining it grey!

I'm using rug underlay from John Lewis, it's not sticky but it is grippy, it works really well

I have the IKEA Stopp Anti-Slip Underlay cut to size of the door mats and rugs.cheap and cheerful and works well.
No experience of the one you have but if you're concerned, replacing it won't be too costly.

The IKEA stuff works well.
