The set is beautiful and sturdy. Very comfortable seating and the blue color is pretty. There is a lot of nuts and screws involved in the assembly. We used a power tool to assemble. We had no trouble putting the pieces together. It took us two hours to get it altogether, when done it will have been all worth it.

Ex Output:
positive

Fits perfect, my old door edge was in bad condition and glue was coming off,Bought the clear door edge guard for my new subaru. Went on like a charm. Just hold a length against the door, cut, push it onto the door, pulling the tape covering the adhesive as you go. Plenty to do all four doors. It is almost invisible.

positive
