How worth it is a sleeping pad?

[wanderlyst]

This has been sufficiently answered but you may still reply if you want.

I've seen a lot of emphasis on sleeping pads and how important they are for warmth and comfort, but i've never used them. I've camped in hot and cold, wet weather without them, and for an unfortunate winter had to sleep on a cement floor with only a blanket.
That all said, I don't quite see myself needing one, but I am also new to Thru-Hiking and I am completely open to hearing other opinions and perspectives.

Thanks for reading
