Be sure to ask the right vetting questions on the person coming out to assemble your products.  First time I used the service, the handyman damaged my table by using an electric hand tool when the instructions clearly noted "not to use."  However, the handyman to responsibility for damaging my table and reported it himself to Handy and Wayfair.  Wayfair immediately refunded the cost for the assembly service, shipped me another table and sent another handyman out to assemble it.  Wayfair has just what I need.  Great customer service.
