The funny thing was I used the Bedgear pillow tool to recommend this pillow. I had previously done the same and loved the pillow, but my wife did too, so we compromised, and she kept it. But I hated going back to my old pillow so I ran the pillow tool again which pointed me to this one. But the recent pillow is a 3.0 whereas the previously recommended one was a 2.0. The 3.0 is very, very thick and perhaps the stiffest pillow I have ever tried. After a few weeks, I determined that I liked it and was sleeping nicely. It does fill out my Bedgear pillowcases though.
