These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.

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!)
