Best pillow I've ever owned
Color: Cut-out White, Size: Queen
While the pillow looks anemic when it first comes out of its packaging, it puffs/firms up beautifully after time in the dryer. I haven't had any odor issues. I'm mostly a side sleeper and at first I thought there wasn't enough of the extra fill, so I put it all in. I've ended up needing to take at least half back out to keep my head at the correct angle. While this can fit in a standard pillow case, it just barely fits and keeps coming out - at least at my fill level. Queen pillow cases are much better. This is so much more comfortable than any of my previous pillows. I don't need to stack multiple pillows to get the right support. I'm no longer waking up with neck or shoulder or arm pain. I'm recommending it to pretty much everyone and I've purchased a second pillow to keep at my parents for when I visit!

So nice your wife will steal it for herself
Color: Original White, Size: Queen
This, this is the god of all pillows I’ve ever purchased. It’s the perfect balance of firm and soft and it’s easily adjustable using the added filler. I’m a side sleeper so having a primary pillow is a must. Combined with a decent secondary pillow this one provides a perfect amount of support. This pillow is so nice, my wife ‘borrowed it’.

Favorite pillow!!
Color: Original White, Size: Queen
Absolutely love this pillow! Bought my husband one a year ago after he was waking up with neck pain. Just recently bought myself one, we both love them! Very comfy and comes with a bag of extra foam to add/remove from the pillow. The zipper on the side of the pillow cover is hidden but durable. We take it with us wherever we go, and always sleep so good.

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!
