Plastic mat in stairs, asbestos?

[DonCorleone]

I have an old plastic mat on our basement stairs that is damaged in one spot. This is not something we did; rather, someone tried to tear away a piece a long time ago.

Has anyone on the forum sent in an analysis of a mat with a similar appearance and confirmed that it contains asbestos? The light foam/cardboard-like layer looks suspicious.

We are going to renovate the stairs and have never thought about this before.

Don't see anything in the picture that looks like asbestos.
Asbestos has fibers like small needles.

I would like to borrow the thread, I have a staircase as shown in the image below. I haven't torn up the carpet yet; is it plastic or linoleum on the steps, and do you think there is asbestos? The house was built in 1976.
