Have plate glass tops cut for the tops of the nightstands if they require protection.

Using mats or doilies kind of went out of style back in 1950

What is the purpose of the mats (i.e. why do you need them at all)? What do the tables look like? What does the space look like?

How about just a coaster or small tray?

I have glass on mine, made by a local glass/mirror company.

I just use a coaster if I feel the need to have a drink nearby. I really try hard not to eat or drink in the bedroom, for some reason I feel like I sleep better when I don’t spend time lounging or reading in bed.

Vintage linen placemats are often the perfect size for nightstands. If you have a collection of vintage linens, try some out.

Glass, of course, can be cut to fit.

For thirty dollars, have a piece of glass cut at any auto glass shop . At 3/8 thickness, it's forever protection and a simple swipe with glass cleaner. Use a coaster for water glasses and condensation. No need with a plastic water bottle.

Nobody is old enough, for a place mat.....save that for your kitchen, please?

I use these small tempered glass cutting boards..you can get round or square…Amazon

thnx for input, just want to avoid wear and tear when I put things on top of table

A precisely cut beveled edge glass top would be the simplest cleanest solution.

You could even put favorite pics / other ephemera under the glass.

Cloths or place mats will be less desirable,as they get dusty and may even slide off ,taking other items to the floor.

Good point, rosiembog.
