It is well designed to match the style and shape of the passenger's seat/backrest. Installs easily - just 4 screws - and mounts easily after installing the base mount. It does provide a great relief for an old back (74 yo) that usually gave out after a couple of hours riding. It is nicely padded and matches the seat color perfectly. Removal isn't too hard with an under seat release but be sure to lubricate the base mount holes deep inside the seat.The bottom of the mount holes are rubber and really grip the seat posts which makes it very difficult to lift up and unmount. I used spray lithium grease applied deeply in the mount sockets. Lithium type grease doesn't dry up and get hard with heat or cold. Use very little.I am 6'1" and would like to have had some forward-aft adjustability but mounted with the comfort seat (back 2") it fits ok. Be sure to order the correct one for the "standard" vice the "comfort" seat.
