we originally ordered the colour Stone as although called ‘stone’ the reviews pictures and the advertised pictures made stone look more of a pale grey compared to the darker ‘grey’ option. 
The colour of the sofa we received was more of a pale brown and looked green in some lights. We were disappointed and arranged a return.. through filing the return It took off £50 from the sofa price for collection of return however after calling Wayfair and explaining the situation they were super helpful and offered a full refund and free collection. Overall the customer service was great, super fast refund. It said refund between 3-5 days and received mine within 1 day. The delivery is super fast too. This one arrived within 4 days and after we returned this one and ordered the grey one instead (which I’m super happy with) the grey one arrived within two days. Sofa of the colour stone and in grey will be attached for comparison. We are super happy with our grey sofa, gorgeous and comfortable!
