I just installed the Iggee beige seat covers in my 91 Legend sedan Type F and am very happy with them. The color blends in well enough. So much so that I did not even use the headrest covers, especially since my headrest do not touch the seats. The fit is tight. They took me about one and a half hours to install by myself. 2 people would be much easier, but I have no friends...kidding...I did this at 9pm after the kids went to sleep. The driver side is harder than the passenger side. I would suggest Installing on a sunny day or have the heat blasting in the car to keep the "leather" supple (this was my option). The "leather" is only the fronts/tops of the seat. The sides and rear of seat covers are a spandex type of material. The seats are comfortable, feel nice, and the tops have a real leather look, too. The only faults are that you lose some of the contours of the seat when you are not sitting on them due to the tightness and the seat controls are covered, but they can still be used through the material. It does look a little wierd having the base of the seat and controls covered, but you only see this part when getting into the car. You can not see these parts when driving or peeking in through the windows and it looks SO MUCH BETTER than ripped or cracked leather and they only cost $84 delivered.
The directions are a little off, but you can figure it out. The directions called for cutting the holes for the headrest with scissors before installation and tucking the material under the headrest buttons...impossible for me to do this, so I installed the seatcover first. Then felt for the holes and drilled a small hole half the size of the headrest hole (careful not to bind the material), then jimmied the headrest thru the holes. Much cleaner look when done and can still use the headrest button thru the material, not that you should need to once you get the height right.
UPDATE to original post- I have since modified the covers to make the base and controls visible
