This are great no-slip pads. They’re easy to customize to the size of your rug and aren’t too much padding. I only gave it 4 stars because they smell horrible and take quite a while for the odor to dissipate. So just be prepared, you might get gassed for awhile waiting for this pad to stop off-gassing. Thankfully it’s been really nice here lately so I’ve had the windows open every day to help get the smell out.
