The mattress was less than 6" though it's advertised as 8". In addition, it appeared stained with an attempt to clean the stains, but they still showed. It buckled on the left side when placed on the frame. In the picture, throw pillows are placed over that spot. Coincidence? I don't know. To Wayfair's credit, they are resolving the issue with a refund. The customer service is considerate.
