SIJO FlexCool Adjustable Shredded Memory Foam Cooling Pillow King

This is by far my favorite pillow! I love how cool it feels to the touch. I also love that the firmness is adjustable by taking out and/or adding more fill. It’s pricey but you definitely get what you pay for.

My in laws love these pillows. They have different preference on the firmness of the pillows - one likes it soft and low, the other likes it firm! Flexcool's adjustable filling is just perfect for them!

My flex school memory foam pillow is comfortable and I get a great sleep and I highly recommend it.

I have literally gone through dozens of pillows to find the right one. I have herniated and bulging discs in my neck. Even drove 2 hours to a hotel where I'd stayed to buy one of their pillows, but turned out not to be the same one. So I was back again hunting for a pillow that wouldn't keep me awake at night. Don't even remember how I got introduced to SIJO, but I took the risk to order my 8th pillow in the past calendar year. All of them are now stored in my basement. I read the reviews and decided to take the plunge and buy the FlexCool Memory Foam Pillow. I liked the idea of controlling the firmness by being able to add stuffing. When I received the pillow, I couldn't believe the feeling of finally putting my head down and not having to move a thousand times to get comfortable. It takes me sometimes hours to go to sleep. I was out in under 10 minutes. Couldn't believe I had FINALLY found the pillow of my literal dreams. I can now actually sleep without tremendous neck pain. I'm a side sleeper, too. I'm ordering an extra one just in case SIJO ever stops making this particular pillow. I can't live without it now. When I go on vacation, this pillow is going with me in my suitcase.

My main goal was to find a pillow that would be cooling. Pillow that I would not have to repeatedly turn in the middle of the night. It doesn't get hot. There is some increase in temperature but not to the point of overheating. The adjustable fiber insert feature is a great option. I had to remove a lot of the fibers but it's my preference to sleep low. The material of cover is nylon I think which is cooling, feels cold to the touch and it's also smooth. Great pillow!

My body naturally runs hot, and I've never found a pillow that actually stays cool to the touch UNTIL SIJO released its FlexCool pillow. I have two King size and one standard size. I used these pillows as my pregnancy pillow throughout my entire pregnancy AND brought them with for my hospital delivery and postpartum stay. I tell anyone and everyone about them.

It’s a good pillow, it is adjustable though I am afraid to mess with adding or taking foam in or out as it will never be as it came to me again and I don’t want to mess up a pretty decent thing. The cover on this pillow is fabulous.

Being able to adjust the thickness of the pillow is a game changer, and the cool touch on the skin is a wonderful experience.

Stays cold, keeps its shape, you can take stuffing out and it comes with extra to customize pillow to your liking

Awesome pillow with lots of fill. My neck is held in the correct position and I fall asleep much faster than with my flat, shapeless old pillow. Love the ability to fill to my preferred fluffiness.

My husband loves his pillow but I am still taking some time to get adjusted and we will see!

Great idea to provide extra filling to customize your firmness. Only complaint is the foam smells a bit funny, but not too terrible.

I love the flex cool pillow. My sleep is quite erratic and I value any improvements I can gain. Your pillow lives up to your claims and provides sleep improvement. Thank you.

Due to the 90/10 ratio of material inside it holds its shape incredibly well and the cooling feature is so good! Such a great choice. Found my pillow.

I am a hot sleeper and my head controls a big part of my body temperature. I've struggled with finding pillows that support my neck when on my back + on my side but also don't heat up when I'm watching my 30-60 minute show before bed. As a combination ADHD sleeper, this pillow stays cold. all. night. long. I'm so obsessed that I have since purchased two kind size and one standard size. I will never sleep on anything else than the flexcool - unless SIJO comes out with an upgraded version of it. lol

I was in desperate need of a pillow upgrade and these are so comfy. Like sleeping on a cloud! The perfect mix of firm and soft/cozy. Love these!!!

i constantly wake up with a stiff neck. ever since i started using Sijo's pillow, I haven't experienced any stiff necks. i actually look forward to getting into bed now because of this pillow. i'm amazed at how it really keeps cool throughout the night. cannot recommend it enough. i am obsessed.

This pillow is hands down the best pillow I’ve ever owned! I imagined it would be soft, but my goodness it’s more comfortable than I could have even imagined! So soft and cushiony and I love that you can adjust the stuffing on the inside to what you like. Get your best nights sleep and order one!

I didn't expect the product like this, it is really comfortable and provides a comfortable sleep, the sleep quality is excellent.
