Love the new pillows! Even though there smaller than my last larger pillows. I would recommend these pillows if you do just want a smaller fluffy ones.

The king size pillows do not offer the same firmness and comfort as the standard size.
Color: White, Size: King (Pack of 2)
I buy a lot from from Amazon and this is my first negative review as this was one of my biggest disappointments. I have bought 7 sets of this Basic pillow in the Standard size over the past 4 years, for my home and my boyfriends, using them both to sleep on and for my pillow shams. I love these pillows and my guests do too, best sleep ever and I have tried a number of expensive pillows prior to this. So when I recently purchased my first king size bed, I bought two sets of the king size pillow of this same brand, and I hate them. They are not the same as the standard size as they are flat, and no matter how much I tried to fluff them up, they fall flat in filling and firmness. After a few restless nights using my new king size pillows, I used the standard pillows I purchased in the past and there is definitely a difference. I see where there are different reviews/opinions on this, but this has been my experience. I will be complaining to Amazon, though not sure there is anything they can do since I used them.

Ok, not as good as before, put in dryer to fluff!
Color: Grey, Size: Standard (Pack of 2)
I have ordered these a few times in the past and loved them. This time they came rolled up and vacuum sealed. Doing that made the pillows flat and feel worn out. I was going to return them, but read that putting them in the dryer on low heat for about 15 minutes helps fluff them. I did that and it definitely improved the pillows. I'll keep them, but they're def not as good as they were a few years ago.
