The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

It’s ridiculous…
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
When I got these pillows I was a little disappointed that they appeared to be a little lumpy. I fluffed and let them rest for a couple of days to see if they’d poof up. Finally figured this was as good as they were going to get. First night sleeping with them…my life has changed! I typically like a lot of pillows. I’m usually a restless sleeper. I fell asleep quickly and slept through the night for the first time since I can remember. No aches and pains as usual. It’s ridiculous that a couple of pillows could have made such a difference in my quality of sleep. Who knew?! I’ll buy these for every bed in the house.

Do not buy, I recommend looking for something else
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
I don't like the quality of those pillows. They don't have any support, super flat, it's like just using the pillow sheet without the pillow. I honestly don't get why this could even be a product. Amazon Basics brand is veryh nice but this one was a very bad one. I usually go with anything but this was worst than cheap airbnb pillows.
