Love the bed frame and head board. Quality and color is exactly as photographed and described. When I selected it, the description of the bed said that a 4 inch mattress was recommended. I am glad I ignored the 4 in and purchased a 6inch. However I think a 10/12 inch mattress would be best for us. The reason why is the slats of the bed are set deep into the frame. For example "4 inches deep!" My 6 inch mattress sits 2 inches above the hard wood frame. 
This makes the mattress lower than expected and described. Understanding it plat form bed that sits lower than a normal bed was acceptable. However the way our bed manufactured and set up by the Wayfair professional team the top of the mattress is extremely low to the ground. Lower than expected and described. I'm hoping to find a way to lift the mattress another 4 to 6 inches inexpensively and quietly to resolved the problem. Any suggestions ?
