The product I bought is excellent, no fumes, right thickness, a little darker than the one in the picture, but still, I love it.  
There was a problem though, I ordered two Eco Plush 0.375" Felt Rug Pad but received only one.  Therefore, I phoned Wayfair and asked what had happened.  The customer representative I spoke to was EXCELLENT: highly professional but with humanity and sympathy; in fact, all the Wayfair customer representatives I contacted were SuperDuper. Phone them if you need to find out what a great representative is. 
They sorted out the problem immediately and I received the other felt rug a week later.  I wish they had been able to have control on what was being sent, but, I was told they can’t until the shipment arrives.  Hence the 4 star instead of 5.  
Because of the way I was treated by the Customer Representatives, I know I can trust the seriousness of this company.
