"MC Interiors was great! They walked us through the fabric selection process, and told us exactly how and when the effort would be completed. Everything went as planned and the job was done several days earlier than expected. So we had our sofa back in time for the holidays, and the men who delivered it to us were very conscientious and pleasant to deal with."
