Best pillow ever!
Size: King (2 Pack)
I love this pillow. I like a softer pillow and my partner prefers a firmer pillow. With these pillows you can adjust it to the comfort level you desire. For mine I took out quite a bit of the shredded memory foam (I call it fluff). I took out one 13 gallon trash bag of the fluff. After I slept on my pillow for a couple of weeks I found it was getting to soft so I took my saved bag of fluff and added it into the pillow. Now it's PERFECT! The cooling side works great. When you lay your head down on it you can feel the cool pillow. Helps falling a sleep easier. I would highly recommend this pillow!

Great Pillows for a Good Night’s Sleep
Size: Queen (2 pack), Size: Queen (2 pack)
These pillows are very comfortable and supportive. They keep their shape well and provide great neck and head support throughout the night. The material feels soft and high quality, and they helped improve my sleep. I wake up without neck pain and feel well rested. Definitely worth it.

BEST PILLOW EVER! - But you must follow these instructions
Size: Queen (2 pack)
This is literally the BEST pillow I've ever slept on! It is SO COMFORTABLE, and I can't believe it was $40 for TWO PILLOWS! I slept on a similar, much more expensive name-brand pillow at my friend's house and thought, "I just HAVE to have this pillow!" When I found this one on Amazon for just $20 a pillow, I was so stoked! However, I was turned off by the "paint-like smell" when I slept on it right out of the box the first night. (I was too impatient to try it out!) Do NOT buy this pillow if you're in a hurry, because to get the paint smell to go away, you MUST follow these instructions: 1. Take the pillow out of its case and wash the case. 2. Leave the case off for TWO WEEKS (yes, you heard right!) to let the pillow out-gas. After waiting for two weeks, the smell will be GONE! Yes, I know it's a long time to wait, but it's WORTH IT! As far as the firmness of the pillow is concerned, I took about five big handfuls of the stuffing out and put it in a ZipLoc bag, but my husband liked the pillow as-is. I personally didn't want it so stuffed and wanted a bit "softer" feeling. I also sleep on my stomach sometimes, so taking out five handfuls of stuffing was perfect. I LOVE MY NEW PILLOW! (One thing I wish, however, is that the pillow came in a standard size. My husband and I have queen-size pillow cases, but our kids have standard-size pillow cases. Darn! I want THEM to have a chance to have such a comfy and inexpensive pillow too!)

The cold side really works. It's nice ;)
Size: King (2 Pack)
The soft side aspect of it is really awesome. We like the whole cold pillow thing but personally I feel like it keeps my head too high up so I wake up with a neck pain. But for someone who likes support, this would be a perfect option.
