Immediately yes
Fill Material: Down Alternative, Size: King Size
I’m 50 and peri has been kicking my butt lately, so temperature management of my head (as that is the only thing effected by my hot flashes) has been an ever pressing project that I’ve been managing for the last 3-4 years. Hot sleeping has always been one of my curses, so adding perimenopause to the mix has been my own special hell. But Dyson fans, keeping the bedroom window cracked, and lots of all cotton gauze blankets have been imperative for me in the night. Pillows have always been pillowing, they just get warm and flipping them all night long is just finding the least hot version. I even keep 2 pillow choices on the bed while I sleep, and 2 more an arm’s length away on the chest at the bottom of the bed. Silk pillowcases are great for my hair and skin but they don’t keep cool. THESE PILLOWS, complete with the Beckham cooling pillowcases are chef's kiss. They feel like they’ve been in the fridge. Literally. Now do they stay that way, of course not. But they’re cool enough for me to fall asleep. And if I wake, I use the other side. And if I keep another on standby, I am literally finding the cool side of the pillow all night long. I’m not exaggerating either. These pillows are cool WITH the cooling pillowcases. You can’t use a pillow protector though, even if it’s cotton. It will ruin the effect. And you must use the cooling pillowcases. Do both, and you won’t be disappointed.

Terrible update to a good pillow
Fill Material: Down Alternative, Size: Queen/Standard Size
Purchased this as I was looking to replace tbe previous Beckham hotel pillows I had purchased before. When I saw "newer model available" I ordered it. Wish I had just ordered the same ones as before. First off this was only 1 pillow, not the 2 pack. Since I was only replacing 1 pillow I decided to use it. Huge mistake, my neck has been sore almost everyday. The support of this pillow is terrible, even with trying to added and remove some fill to adjust it. Nothing seems to make a difference. Avoid it and order a different model. Wish I had sent it back for a refund when I got it.

Best Pillow e
Fill Material: Down Alternative, Size: Queen/Standard Size
I’ve been using this pillow for 3 months now. It is, hands down, the BEST pillow I’ve ever had. It’s soft and supportive at the same time. As I noted, I’ve been using it for 3 months and it has maintained its loft unlike some of the other types of pillow I’ve tried. Well worth the price and I highly recommend it.

Absolutely Amazing!! Truly the perfect pillow!
Size: Queen / Standard, Color: White
I absolutely love these pillows. They couldn't be more perfect! I have spent years buying and throwing out pillow after pillow. I struggle with a lot of neck and upper back pain and I struggled even more trying to find the right pillow on top of spending several hundred dollars on pillows that just got tossed. If you want a great night of sleep and you want to wake up feeling refreshed and not struggling with fatigue and every day neck or back pain you absolutely MUST give these pillows a try!!! They are super easy to wash, made with great quality and have not once bothered my many allergies like most pillows do. I have not noticed any of the chemical odors moat pillows give off, easy to adjust does great with just occasional fluffing. So far has stayed fluffy for me although I did put it in the dryer a time or two as the instructions stated to help with extra fluff and also because I couldn't wait for them to air fluff when they first arrived, an Air B&B we stayed at had these and I ordered them before we even headed back home I loved them so much I had to order my own and was too impatient to wait!
