What kind of coasters do you use?

I bring some back from holidays, so I have a colourful selection. Mostly cork.
I don't have any sticking problems at all.

I don’t have any, my table is a scrubbed wood one and anyway it’s never used as no one comes for a meal anymore

These are mine.
Slices of mineral/rock with irregular edges.

Very heavy.
Don't seem to "stick" - probably too heavy to do it!

Avoid wet bottoms.

Good advice!

I had some cork ones in a holder but they kept tipping out so they went to the charity shop.

Mine are square wooden ones, bought from Woolworths many years ago.

They stack in a wooden holder.

Yes, glasses stick to the bottom, but I am ready for them!

Mine are slate, I’ve had them for a long time and they still look good, but I think marble ones would also be non stick, and they are in vogue at the moment.

I can't abide coasters and there aren't any in my house because of the way they stick to the bottom of glasses etc. All the surfaces where anyone might put a glass or a mug and leave a ring are well-varnished wood, laminate or glass and so easily wiped clean.

Mine are slate , no sticking to the glasses

Mine are mostly cork. Sometimes I use anything lying around...!

My Christmas ones are lovely

I have slate , wood turned (by my now-departed brother), glass , slate and plastic, and custom-made plastic coated done with GS son’s hand writing (don’t ask me how )

Square cork, always dotted around on side tables

I have a vast and varied collection, bought over the years with some lost along the way so none match. Mainly cork with pictures on the front.

Wooden ones, bamboo ones, laminated ones, glass ones.

Coaster City here 😁

I have Beatles album cover ones. Cork with plastic fronts.

Cork and rush ones seem to work for me. I think the secret is to try and avoid mugs, glasses or whatever having a wet bottom when they are put down.

I have glass ones but they do what you describe maybe cork might work.
