Hi electricrelish,
I don’t have any personal experience with any of the pillows you mentioned and a quick search didn’t turn up any feedback on the forum about them either but hopefully any of the members that have used any of them will see your post and share their comments and feedback about them.
The Sensorpedic pillow sounds more like it uses one of the newer generation of polyfoam materials (see post #2 here) and doesn’t sound like memory foam at all.
I checked the Totillow site as well and clicked on the order now button on this page but it just leads to the same page and I also don’t see any prices anywhere on their site. It also says “Totillow Down Synthetic Posture Pillow now offered at AMAZON.com” but it’s not currently available there.
According to the cached Amazon page here and the Kaboodle site here they were selling for $79 when they were available.
