Has anyone tried these pillows out yet? Currently on sale for $39 each. $10 off.

I've been dying to replace my old pillows.

I noticed this new pillow: https://www.costco.com/.product.1804267.html

However, that pillow has the exact same name and almost identical description as an older pillow: https://www.costco.com/serenity-by-tempur-pedic-cooling-memory-foam-pillow.product.4000205431.html

Despite the similar names and descriptions, the pictures look very different, with the older version having a gusset around the edge.

My 6-year old pillow is flat as a pancake, so I've been eyeing these products. Does anyone have any experience with them, and do you know what the difference is between these 2? I asked Tempur-Pedic what the difference was, but they gave me a dubious answer, saying one of them was higher than the other. The description states that both are medium support.

Update: I saw the first pillow I linked, the new one, in the warehouse today so I bought it. The first things that popped out at me were that it was pretty small, so my pillow cases and pillow protector are going to have a couple of inches of loose material on 2 sides. Also, that it was giving off a strong smell after I removed the airtight plastic wrap. Lastly, my hand sinks down further than I expected when pressing down on it. For now, it’s sitting on the couch off-gassing. Hopefully that only takes a day or so. Right now, I’m estimating a 60% chance that I’ll end up returning it.
