Love these pillows!
Size: Queen (2 pack)
I’m a side and stomach sleeper. I’ve bought so many pillows recently trying to find one that doesn’t kill my neck or shoulder. I felt like I was looking for a unicorn. For some reason this pillow just works. It has a higher loft, which I prefer, but it’s also super squishy, which I also prefer. It somehow has the best of both worlds. They feel high quality, are adjustable in terms of density since you can remove as much filling as you want, they actually fill my pillowcases so they’re not flopping around the pillow, and they maintain their shape after a full night of sleeping on them, the price point for two pillows is just right, and best of all, they actually stay cool. I am a hot sleeper so that last point is worth the cost of entry all by itself. I have no neck or shoulder pain after getting a full night’s sleep on these pillows. The only negative is the initial smell of the pillows. It’s pretty strong, but I’m sure this will lessen over time.

As advertised for once! Lol
Color: Cooling Blue Cover, Size: Queen (Pack of 2), Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Queen size set of 2 pillows, I'm giving it 5stars first bc it has a good length and width!! If you've ever bought memory foam pillows before you know some are small!! Anyways after having it for 5nights, we loved that me and my huddy could adjust the Thickness amount we had in it to our needs, me needing a thick pillow and my husband needing a flatter one. So this was perfect for that. So far its nice to sleep on, stays cool, doesnt get hot. I would say its on the frimer side but softer the more foam you take out! Really its just good for the amount you spend!! Will it last 10years probably not but what does now a days. This is the only time my huddy n I bought the same pillow and both love it so I'm just still in shock it worked out so well!!

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.
