Really wanted to love these
Size: Queen(Pack of 2)
I really wanted to love these but they gave me a stiff neck. I haven't slept with a pillow since buying these. They are firm except where you lay your head. It just deflates there. I expected it to sink in to match the curve of my neck but it was more than I could handle. My head ended up in a valley between the two ends of the pillow. The price was good, zipper worked fine, it looks as advertised and the pillows are good quality. The cooling part works, its just not what I needed.

best pillow I have ever bought.
Size: Queen(Pack of 2)
most comfortable pillow I have ever bought. It seems very well put together so I believe that it will last a long time. Very happy with the purchase. I do think the weight of the pillow will surprise many people because while it is quite heavy, it is very firm and extremely comfortable. Great value.

I paid for the product and it’s GOOD 👍🏽
Size: Queen(Pack of 2), Size: Queen(Pack of 2)
Honest review to help your decision. These are a bargain at two for one. I paid almost $30 for one at a local retailer and it’s already flattened after 7 months. This product arrives vacuum sealed with the cooling pillow covers separately (separate so you can wash before using). They are loaded with memory foam which I found pleasing. I chose to leave all of the foam in because I’m sure it’ll flatten sometime in the future. I’ve been using these for TWO MONTHS now and they have not flattened. Easy to mold and fluff, soft and they are added support for my back up pillows. I cannot attest to any type of pain relief because I have not experienced that with these personally. I do feel my sleep is better so my tension headaches have lessened. The cooling hex layer is on the cover NOT the actual pillows. I’m sure everyone knows that memory foam gets really hot 🥵 but the cooling covers on these help minimize that. It actually feels cool to the touch like a gel product. I find the quality to be exceptional. All in all, give it a shot.

More soft than firm
Size: Queen(Pack of 2)
Not firm but more soft, would I be returning probably not but if you were already on the fence this is your confirmation that it’s not as described, ( well to my standards at least ) it does feel of good quality but I was looking more a sturdy firm that soft and cushion feeling .

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.
