Absolute rubbish, if Wayfair didn't want £16 to return I would have sent straight back.  What a total rip off.  They are not grey, they are brown and white polyester, I have seen better in a supermarket, shocking quality.   These are off to landfill, over £60 down the drain.
Wayfair returns policy is an outrage, long distance trading rules state I am entitled to return for FULL refund including postage.   But you have to use Wayfair delivery methods only for the return and they charge what they want.
