We use this underneath a carpet in the laundry room to help with fatigue. We love it.

Excellent mat. Great material very durable.

It looks amazing with my bamboo curtain...really ties the look together!

smells of chemicals and needed to be aired out but seems to work ok

Like this mat because it is sturdy and yet fairly lightweight and flexible. It does a great job of protecting my carpet, and my recumbent bike never slips or slides on it. (By the way, I made sure to measure my spinner when it was set up so that I would get the right size mat. Genius move, yes?) I've only been using it a month-plus, so I cannot as yet speak to the mat's durability. So far, I think it's a great buy.
