F1 Cooling Pillow - Adjustable Air and Water Pillow for Neck and Shoulder Pain, Revolutionary Fusion, Customizable Support and AI Sleep Sounds for Ultimate Comfort

Companies who sell “cooling “ pillows are a JOKE, except for this one! I was VERY leery when I open the box! I was like I have to assemble a pillow? It sat in the box for two weeks, and my husband made me put it together. I had a cooling pillow for probably eight years. My puppy ate it. I tried to replace it with at least 10 different pillows, still could not find the same one. I ordered multiple ones off Amazon and bought from retail stores! If you are looking for COMPLETE COOLING comfortability and a good night sleep, this is it.!!! best pillow I’ve ever had in my life. You do have to fill it up with 14 or so bottles of water. It has a built-in air pump to pump up the other side, which can be pumped up at any time easily! It comes with a preservative tablet that keeps the water fresh for six months before you need to change it. I have had it for a month and a half And have a hard time sleeping without it. It seems like a pain in the butt, but it is so well worth it.

I rate any product that does not meet the product description with a maximum of 2 stars. This product fails to live up to at least two claims in the product description, and at almost $180 at time of purchase, cannot justify the price point on this pillow. Even without these considerations, I would probably rate this pillow at a 3 star overall for construction design. That said, I do enjoy sleeping with the pillow and find I gravitate towards it.False or misleading Advertising:1. The product description and images claim a silk covering material. Silk is not listed in the materials of the pillowcase tag, and as someone that owns a lot of silk, can confidently say the material in use is not silk. It's some sort of poly material, derived from oils.2. The product description claims "AI-assisted sleep sounds". The tag on the pillowcase includes a QR code that you can scan and have another device play the sounds. I find this description misleading at best, as nothing in the purchase gives you sounds. The QR code doesn't have authentication associated with it, so is no different from linking to a playlist on a generic streaming site. Anyone with the URL can access - no purchase necessary.Cost: This pillow consists of two (heavy duty) plastic bags, some velcro, a one-way air valve, a water-tight valve, and some spongy material. Admittedly, there may (emphasis on may) be some IP or research that's gone into optimizing the experience, though when considering the materials this pillow seems more appropriate at a $40 price point, although it's possible there are a few tricky bits in manufacturing. Perhaps a $60 or $80 price point is explainable if targeting a "luxury" market.Design: The pillow consists of two main plastic bags. An air bag and a water bag. The two are velcro'd together. The size of the bags is not the same, so one bag gets scrunched up to align the velcro with the other bag. There's a valve for each bag, though they don't align to the same corner of the pillow, so two of the corners have hard sections where the valve stems exist. The water bag has a valve that makes it difficult to get all the air out of the bag once you've filled it to the "fill" volume. This is important for two reasons: getting the air out of the water bag helps reduce sloshing and overall noisiness of the pillow while it is in use; and second the water is supposed to be changed every 6 months and a new purification tablet placed inside. It's the only aspect of the bag that needs a regular maintenance cycle, though it's the worst experience to get setup right.Setup: This pillow has some assembly required. Expect to need 15 - 30 minutes to get it up and running. A few tips: the built in air pump on the air bag is on a one-way valve of sorts. Leave the plug out of the valve when pumping up the air bag. If you need to deflate the air bag then you push in on the way way valve and it releases air. The water bag is easier to remove air bubbles if you submerge it, say in a bathtub - this helps you force the air bubbles out.General Thoughts: This pillow is basically a water pillow with some baffles. The water provides a passive cooling effect by acting as a big heatsink. There is no active cooling, and there doesn't appear to be any piping in the bag that would actively help circulate the water as a section warms up due to body heat.The pillow holds about 5 - 7 liters of water, or approximately 1.5 gallons. That makes the pillow just shy of 15lbs. My wife calls it a brick and has given up all hope of moving it wherever it happens to be on the bed.All said, I do enjoy sleeping with it most of the time, and it does keep me noticeably cooler in circumstances I would have otherwise been overheating in. The product design, marketing, and price point all just need some work to really bring this together.

This was a difficult review for me to write. While this pillow has some design flaws, I'm having a difficult time imagining how I'd have a good night's sleep without it: This is maybe the best compliment I can pay it. So on the one hand I believe The high price point and design flaws limit this pillow to two stars. However, in spite of the high price point and design flaws, this pillow has become an integral part of my sleep routine. My head has never been cooler. I've never felt the urge to flip the pillow over or move my head to a different section of the pillow to find a cool spot. For that reason, I'm giving the pillow three stars.Set Up ---------------------This is the first pillow I've owned that requires setup. Set up was time-consuming and awkward, compounded by instructions that were somewhat unclear. Filling the water pouch of this pillow was… interesting. The capacity of the water pouch is significant. Pro tip: Definitely DON'T set up the pillow on the bed or anything else you don't want to get wet with blue water. Pouring that much water into a smallish hole in the water pouch, while keeping the hole elevated enough to avoid spilling the now blue water from the included disinfectant tablets is difficult to say the least, especially as the pillow grows heavier with water. You then have to squeeze the water pouch to remove any remaining air, insert a foam plug, screw on a cap, and line up the Velcro strips to adhere the water pouch to the air pouch. With the air pouch inflated and the water pouch filled, you now have a rather awkward, probably 15-20 lb. pillow with a tendency to flip over. You have to then wrestle the included cooling pillowcase over the pillow, zip it up, and slip your own pillowcase over the pillow before carrying your toddler sized pillow to the bed. Position the pillow carefully before you go to sleep because repositioning the pillow is actually like dragging a 20 lb. baby across the sheet. My wife has to actually sit up and pick up the pillow to reposition it. Once it's set up though, you're good to go for a few months until you have to change the water and repeat the process.It Really Works --------------------The pillow works. Water has a high specific heat, meaning that it takes a good amount of energy to change the temperature of water, which is why water takes as long as it does to boil. The air in the bedroom has all day, presumably, to heat or cool the water in the pillow until it matches the ambient temperature in the bedroom. This is important. Since there's no internal heating or cooling source in the pillow, the pillow will only ever be as cool or warm as the air temperature in the bedroom, given an adequate amount of time for the temperatures of the pillow water and bedroom air to equalize. Since it's likely that your bedroom air is cooler than 98 F, the pillow will always be cooler than your body temperature. When you rest your head on the pillow, your head begins heating the pillow. However, your head is only heating a small portion of the pillow and the ambient temperature of the bedroom is continuing to cool the pillow, albeit at a rate slower than your head, which is warmer and more efficiently contacting the pillow. This means that for some, if not all of the night, the water in the pillow is going to be cooler than your head, even if it's only by a few degrees. The idea is genius really. The design execution is lacking some, though.Improvements --------------------I can live with a time-consuming setup and a heavy pillow, it's to be expected. However, I'd really like the water pouch to be thicker and softer, hugging my head just a little like a normal pillow. Between the weight of the pillow and the weight of my head, the pillow sinks into the bed. Not a lot, but it still happens. So to make the pillow thicker, I have to inflate the air pouch more, which makes the pillow firmer than I'd like it to be. Without air in the water pouch, the water pouch flattens out, and then I'm then left with what feels like laying my head on an innertube or a water wing with a very thin layer of water on top.

Love the cooling effect of this pillow plus it is comfortable!
