I had pretty much the same issue with the seat on my 4300. The yellow foam separated from the black base. After a little research decided to purchase a grey one on ebay. They is one there now listed as item no. 150370231298 it is 140 bucks shipping included. I have had it for a year or so and still looks like new. They also have some on ebay yellow, not sure of the quality for 76 bucks and 14 shipping item no. 180471489853
Hope this helps
