That's funny. I, too, have an old latex pillow from PCF...when they were making them for Sealy. It's several years old, and I still use it.
Just like an all latex mattress, there's nothing like a latex pillow.
Of the ones on this page, the one that feels most similar, is the Pure Bliss Soft Talalay...the first one on the page. I use this one, too...but sleep in all positions.
The second one, the Danican pillow, is a better choice of you are strictly a side sleeper.
