I bought this bed a few months ago, and stored it for the duration of a bedroom remodel.  The finished bed is sturdy and very attractive, no nicks or dents in the finish.  The area provided for a full-size mattress is generous, so even the widest ones should fit easily.  I contacted Wayfair customer service prior to purchase, and they confirmed this bed frame is not intended for use with a box spring.  There is about a 8-9" clearance for under-bed storage access.  The only negative comment I could make about this frame is that it took significantly longer to assemble than the 45 minutes suggested by the manufacturer.  Your mileage on that account may vary, if you have assembled similar projects, or are particularly good with diagrams.  I am very pleased with my purchase and can easily recommend this frame to others who like the style and price.
