We are very, very pleased with our first purchase here at Wayfair. We purchased the Zip it comforter set and the 10" memory foam mattress for our 8 yr old daughter. All items arrived on time and intact. My daughter loves her new comforter set and now I wouldn't worry about her making her bed each morning since it becomes an easy breezy task for her.  
I am so happy with the memory foam mattress. The quality is great and it did not have any bad smell at all, as what others are saying in some of the reviews. It also did not take long to get it into its shape after unpacking it. 
We will definitely buy from this site again :)
