The cross brace over the landing gear was extended up about two inches with a plywood and balsa wood brace/flange for the front of the seat to rest on.  This was glassed over and the locking mechanism for holding the seat bottoms down will be placed in it.  The hinge for the rear of the seat bottom was also raised about two inches to maintain the same angle for the seat bottom.  

The result should be a seat that is high enough to make it comfortable for most adults without causing problems with head room.  A very nice sized area is available under both seats for storage of valuables under lock and key.  The full rear seat will fold forward for access to the luggage area.  One additional modification which is not easily seen is the center console section is removable to provide access to the flap control connections.

Memory foam in three densities was used to fabricat the seat bottom padding.  The lowest level is green and is the most dense.  The blue layer is the thickest and is a medium density.  The top, pink layer is the softest.  The seats were shapped to provide a comfortable and firm seat.  The initial impression when you sit on the memory foam is that it is way too hard to be comfortable.  However, after sitting on the seats for a short time you will find them very comfortable because they tend to warm and shape around you.
