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.

Super comfortable!!!!

Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow

They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.
