  • Lives up to its claims
Size: Side Cube
Pillows will always be incredibly subjective to each person but after trying many, many of them over the years, this one truly lives up to its billing and is a side sleeper's best friend. The key features for me are the rectangle shape which snugs up great against your neck and shoulders then the foam itself which is a single piece and the best I've personally experienced. My head settles into it but never bottoms out and is then cradled which results in excellent sleep and no sore neck. Money well spent. ... show more

  • My new favorite pillow.
Size: Side Cube
I’ve been looking for a pillow that is firm, cooling and provides the right amount of support for side sleeping. I thought a cube shaped pillow would be a gimmick but after watching their video, i decided to give it a try because it looked like it actually could do what they say it does. I ordered my pillow and it came flattened and vacuum sealed. After removing it from the vacuum seal, it plumped immediately. It did have a slight chemically smell but that dissipated quickly. After two nights sleeping with the pillow I realized I had ordered the wrong size for my height. I ordered regular size for individuals over 5’ 3”. I am 5’1” and I found that the pillow was too thick so I wasn’t getting the proper alignment. So when you order, be sure to make sure you order the correct size pillow for the height/size. I sized down to the thin, which turned out to be perfect. Upon opening the pillow, I did feel like the thin wasn’t has firm as the standard but it turned out to be fine. The pillow looks like a cute rectangular block. The pillow casing is very soft and cool to the touch. I will say that the pillow does stay cool for a very long time. When I’m ready to sleep, I tuck the pillow between my shoulder against my neck. Once I lay my head down on the cool pillow, I fall asleep pretty fast. The pillow is comfortable and most importantly, the firmness is giving me the proper support to keep my spine aligned. So far I’ve been sleeping on this pillow for about a month and I really love it. Most pillows lose their firmness and therefore lose the head and neck support. I have high hopes that this pillow will remain firm for a long time. I’ll try to remember to do an update after 6 months of using this pillow. For now, it’s definitely a recommend from me! ... show more

  • Really good for medium shouldered side sleepers.
Size: Side Cube
A really good pillow for side sleepers with medium to broad shoulders who don’t roll onto their backs. I thought I could use this to keep me on my side. It was well made, really comfortable and uniformly shaped. It doesn’t taper towards the edges. This was nice at first since you get uniform support anywhere along the pillow. Unfortunately I found myself rolling onto my back throughout the night so my head was really tilted forward. Somehow I never woke up from this and it made my neck pretty sore. Since this pillow was already a little too thick for me, this was really bad for my neck. If you don’t roll, this is a really supportive pillow. I gave it four stars since it’s such a high quality pillow. If you don’t roll at night this is worth the price. I ended up going with the Coop pillow as it allows you to add or remove filling to personalize your fit and it tapers towards the edges. That’s been much more comfortable for my neck when I roll on my back. ... show more

  • Will expand and smell
Size: Side Cube
The box pillow came in a 'small' box. It is a foam cube inside of a pillow case with zipper. After un wrappiig the plastic around the rolled up deflated pillow it will take on air and expand to the pillows intended size. What I noticed right afer this enlargement was a smell kind of like a hobby glue or maybe turpentine (we all smell things differently) that permeated the pillow cover which was around the foam. Took off the pillow case and discovered that the smell was coming from the foam inside. What to do. Return means findiing a larger box. So went to the product makers website through Amazon and this is some of the Chat, like chat because it gives a text to refer to at a later time. The answer shown here, surrounded by """, was right away so this situation must exist with other purchasers: """ System (Pillow Cube) Nov 3, 2023, 12:36 PM MDT (12:34:19 PM) *** John joined the chat *** (12:34:20 PM) John: Just opened up a pillow cube ordered through Amazon. Why does it smell. Washing out cover but the smell comes from the foam insert. Not wanting to sleep with the pillow if it continues to smell like a hobby glue. (12:34:45 PM) Aly: Hey John, All of the foam we use is of the highest quality. We've seen that if the pillow is packaged quickly after the foam is made, it will have a stronger smell. Luckily, the smell WILL go away. The easiest way to speed up that process is by setting the foam core out in the sun in the open air until the smell has dissipated. We'd also recommend washing the pillowcase and pillow cover. """ After two weeks of putting the foam out in the sun and later letting it sit out in the garage and then later in the house there is still a slight lingering smell. The pillow case hand washed out the smell after a couple of washes. Have not used the pillow as of this writing. Not sure what will do ultimately but wanted to pass on this information. ... show more

  • It works!!!
Size: Side Cube
I have had this pillow for about two months now, and I am no longer waking up with neck or upper back pain. (Thank you!!!). I am a side sleeper, and at first, the cube felt very uncomfortable, but after a few days, I got use to it and the pain was gone. Amazing! It’s the best pillow I have ever bought for myself. And, I have gone through a ton of them. ... show more
