Seat Cushions Help

[Mkliebert]

I recently bought a 2007 Maxum 1900 SR3 with the removeable seat cushions on the right that makes a walkway to the swim deck. The boat is missing one of the cushions the seat or bottom on the far right side. My question is if anyone has a similar size and configuration if I could get the dimensions of that seat so that I could try to get it rebuilt. TIA
