How the chuff do I dry memory foam?

[CreeperSutherland]

DS peed on DDs fold-out chair bed thingy, so I washed the foam pads in the bath.

Now I can't get them dry!
They seem to be a really dense memory-type foam.

Too heavy to hang.
To big for the machine.

Help! I need the bed for the weekend!

With a hairdryer?

Prop it against a heater with some towels underneath?

Thanks for the replies.

I have tried a variation of that, COG, to no avail.

Maybe a combination of the two will do it.
