Best fluffy but firm pillows
Size: King(Pack of 2), Size: King(Pack of 2)
These pillows are worth every penny! They started off pretty flat but after three days they plumped up well. In addition to them being plump, they are also firm. Exactly what I was looking for. You can shake up the internal stuffing if you want them softer too. They were a bit pricey but I’m going to repurchase and replace all my home pillows with these. I do sleep hot and the cooling side is perfect to lay on. Kept me cool and comfortable. I haven’t had any neck or back pain after switching to these pillows too. Absolutely recommend these for your home. The photo shows how full the pillows are. I have four pillows in the picture plus two smaller other brands. These are definitely fluffier.

Great Quality
Size: King (Pack of 2)
Great quality and definitely worth the money. The cooling effect actually works with the pillow. Extremely comfortable, not too squishy and not too firm. To me, it feels very supportive.

Very comfortable, luxurious, and affordable.
Size: Queen (Pack of 2)
Great pillow. Feels soft enough for comfort while being cool and cozy. There could be more filling to make it slightly more firm but otherwise a great pillow.
