Disappointed...this is a Beauty Rest brand supposedly (quality & dependability?) ...the size for a standard full mattress is 54' x 75"  The mattress I received is 52.5 X 72.5...This leaves a considerable gap once all around once it's placed in the bed frame, not too mention too "short".   The frame is the perfect dimensions 54 X 75, so I know it's not the frame.  This is a lousy excuse for cost savings.  Too big to return so I will live with it but not happily...
