Heavy! When they tell you you need 2 people to install you do it weighs 98 pounds. Design is sleek and modern and only 2 issues. The supplied screws to attach the toilet to the plastic piece(sorry that's what the part is called) were too short so I need to purchase larger screws but in the picture the plastic piece is shown on a 90 degree angle but the part is actually on a 45 degree which makes the screws too short. 2nd issue is the toilet can move since there are no bolts to hold it from moving side to side as in a regular install where the bolts come up from the floor.  Simple solution was to install 2 pieces of wood behind the toilet and up against the wall.  This secures the toilet from moving side to side.
