how do I get the water out of my seat cushions?

[JasonG]

We have a 5 year old boat that got it with rain heavy while the cover was off. The seat cushion foam got wet in many cushions. Shy of cutting the seat apart, how do I get the water out of the foam?

The seats are in fantastic shape, so I am not keen on opening them. I let them drain on a seam which helped get water out.

thanks!
