There’s a common misconception that thicker carpets are better. That's not always true. If sustainability is what you’re looking for, then you definitely need to opt for thinner carpets.
To decide on the thickness of your new carpet treads, take a look at your stairs. If each step is short, you should opt for thin ones as thick carpets will cause accidents when they wrap around a step’s edge. For stairs that are high or lengthy, you can opt for any type of treads.
