If it's open cell foam... you are right. It's basically a big sponge. Certainly not suitable for any machine washing or drying. If it HAD to be cleaned... I'd hand wash in a tub. As you push down it will expell water, when you release pressure, it'll draw water in. Rinse & repeat. Keep changing the water. Switch to dry tub or drainer... squeeze water out. You might have luck drying in air current like a fan, on a raised drying rack. Water will tend to move down from gravity. Probably still slow drying.
Can you substitute foam from an upholstery store temporarily? While it dries.
I keep a washable cotton towel or thicker bath mat on my favorite seats... as a layer to reduce risk.
