Bought the twin size.  Weight limit in the product description says 250 pounds and that feels accurate.  Very easy to assemble.  The fabric that goes around the frame had some wrinkles that smoothed out by the next day.  It completely encases the frame with a zipper closure. ***This sits taller than 16" high, NOT 14" as described because the frame is 9" + the optional wooden legs are 7", so take that into consideration when figuring how high you want your mattress to sit.
