Was looking to buy a rug online from argos but didnt know whether it would be soft or not, prefer a soft rug here is the advert
Polypropylene is less soft to the touch then some other fibers like wool, nylon and polyester.
It's not as soft as wool, but it's nothing as bad as walking on sisal. One thing I don't like about polypropylene is that it becomes matted easily, and it doesn't pop back up when it's vacuumed, like nylon pile rugs do.. Rather, the threads seem to stick together, and if you have to scrub out pet vomit or spilled mashed potatoes, it seems to matt even more. It's a nice-looking rug, and most likely a great price, but I'd keep looking.
