Customer photo review of Onyx AeroMatrix™ Pillow

This was certainly one of the more unusual pillows that I've ever seen and used, but that being said it's also been one of the best. The comb structure does do a surprisingly good job of keeping the pillow cool for quite a while before it normalizes in temperature throughout, and even then it still remained cooler than every other pillow I've used except for a buckwheat hull pillow. The material is a has a nice soft and springy texture that isn't too hard or too mushy, just enough to be supportive. Normally I sleep on my stomach, but with a recent hernia injury I have been sleeping on my back which has been extremely comfortable with this pillow. I use the shallower side for a lower loft. Probably my biggest problem is trying to keep my cats off it since they enjoy it as much as I do lol.

Whoa it's bigger than I expected but unusually comfy to sleep at as a side sleeper. Wish it was more lighter tho but no biggie :)

Waited five months before leaving this review because I wanted to see how it held up. Well, I was not disappointed.

Customer photo review of Onyx AeroMatrix™ Pillow

first two nights were rough ngl. felt too firm and i was annoyed. left it in the corner of my room for like four days and then gave it another shot. something about it just works once you adjust. i think my old pillow had my neck in a bad position for so long that the correct position felt wrong at first lol. anyway i'm glad i didn't return it.

Customer photo review of Onyx AeroMatrix™ Pillow

My friend mentioned it in a group chat and I impulse bought it at midnight! Did not expect it to become my best purchase of the year so far but here we are. Great support which doesn't flatten through the night. I also how cool it gets. I've been a notoriously bad sleeper my whole life, like the kind of person who wakes up three or four times a night, but it has been less and less with this pillow.

Onyx AeroMatrix™ Pillow

Customer photo review of Onyx AeroMatrix™ Pillow

I used the Purple Pillow for months and wanted to love it, but it just never felt right for my back The Onyx Pillow feels more supportive and comfortable, especially for side sleeping. I don’t wake up sore anymore, which honestly surprised me. Tbh, I was skeptical about the ads on it at first but it's lowkey an underrated product.

Onyx AeroMatrix™ Pillow

Customer photo review of Onyx AeroMatrix™ Pillow

It's almost perfect. I really like the cooling and the shape of the pillow. It took a few nights to get used to, and the support could be slightly firmer, but once I adjusted, my sleep quality definitely improved. I'm actually planning to gift one for my wife!

Onyx AeroMatrix™ Pillow

Customer photo review of Onyx AeroMatrix™ Pillow

I’ve tried a few memory foam pillows before and always hated how they either felt too stiff or sank too much. This one is on another level. It supports my neck without that “stuck” feeling, and it doesn’t lose its shape overnight. Way better experience overall. No regrets so far

Onyx AeroMatrix™ Pillow

Customer photo review of Onyx AeroMatrix™ Pillow

I've been seeing ads for this pillow and finally took a leap of faith to order it. I used to own a Purple Pillow so my expectations were already high. Safe to say, it did not disappoint. It feels really cool at night and I'm glad I don't have to wake up anymore flipping my pillow over and over again. I guess the only downside is that the support isn't that great but everything else about this pillow makes up for it.

Onyx AeroMatrix™ Pillow

Customer photo review of Onyx AeroMatrix™ Pillow

This pillow has done wonders for my neck pain. Used to go to go to bed every night dreading the moment I wake up but since using the Onyx Pillow, the area behind my neck has gradually improved. It wasn't a magic pill that erase the pain away, btw. It was a gradual process but well worth the price.

Onyx AeroMatrix™ Pillow

Customer photo review of Onyx AeroMatrix Pillow

Finally a pillow that doesn’t trap heat. My old ones used to get so warm it woke me up. Ever since using the Onyx Pillow my sleep score has actualy gone up. Super happy with it.

This thing feels super cool to lay on and it supports your neck really well. My girlfriend liked mine so much she took it, so I ended up buying another one lmao.

Customer photo review of Onyx AeroMatrix Pillow

My chiropractor kept telling me to get a better pillow and I finally listened. Honestly should’ve done it earlier. My neck doesn’t jam up anymore and the cooling is actually real not just marketing speak.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

Working remotely totally destroyed my posture. This pillow has helped SO much. My neck pain is wayyy less than before and I sleep more comfortably without tossing around as much.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I could feel the differance after the first couple nights. My neck feels aligned now and my shoulders aren’t tense when I wake up. Defenitely recommend if you’ve got neck or upper back issues.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I sleep on my side and this is the first pillow that actually feels right for that. It’s soft but still holds my head up properly. Cooling is legit too. Probably the best pillow I’ve bought tbh.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

As a mom I’m always tired so anything that helps me sleep better is a win. This pillow is super comfy and supportive. I don’t wake up with neck aches anymore and I for sure notice I sleep deeper too.

Customer photo review of Onyx AeroMatrix Pillow

Since working from home my neck has been a mess. I bought Onyx kinda out of frustration and didn’t expect much but it actually helped. After like a week the morning stiffness was basically gone. Wish I got it sooner lol.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I tried soooo many pillows trying to fix my neck pain and nothing worked until this one. The support feels strange at first but then you get used to it and it feels amazing. No more waking up with knots in my shoulders either.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I’m a runner so recovery matters to me and this pillow actually made a noticeable differance. My neck feels less tight in the mornings and I’m not tossing around trying to get comfy. Pretty impressed honestly.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I used to constantly flip my pillow cause it got too warm, but this one stays cool without me doing anything. Honestly didn’t expect much but wow it helped my sleep alot. I fall asleep faster and stay asleep longer.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I sleep on both my back and side and this pillow works great either way. The contour actually holds my neck in a good position so I don’t wake up all crooked. Way better then anything I bought from Amazon before.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I get headaches pretty often and someone told me my pillow might be the problem. Turns out they were right lol. After using Onyx for about a week the morning headaches pretty much stopped. Super comfy and doesn’t flatten like other pillows.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

I switched from a cheap memory foam one and wow, this thing is on another level. I used to wake up with my neck feeling tight and stiff but now it feels way loser and relaxed. Cooling is definetly real, no more sweating on the pillow.

Onyx AeroMatrix Pillow

Customer photo review of Onyx AeroMatrix Pillow

The Onyx Pillow honestly surprized me. I didn’t think a pillow could make such a big diffrence but after a few nights my neck pain was almost gone. The cool grid feeling is super nice too, it stays chill even when I sleep on one side for too long.

Onyx AeroMatrix Pillow

Overall it's a comfortable pillow however I feel like it could use a more ridged outer structure with it being as loosely contain it shifts a lot and that leads to a feeling of lack of support and a most like it flattens and doesn't support around the edges

Onyx AeroMatrix™ Pillow

I love this pillow finally something that's innovative and does what I want , I don't fight this pillow and it's always cooler than any other pillows I've owned.i have 8 different pillows but it's just for decoration now I use this for sleeping. I wish anyone reading would just give it a try we deserve to sleep better

Onyx AeroMatrix™ Height+ Inserts

it s a little low in lift. 5 winches would be good for me.

Shipping protection

Very heavy and hard to adjust. It felt ok the first couple of days but by the third day I had some serious nick pain.

Onyx AeroMatrix™ Pillow

Extremely susprised by how comfortable it was. I thought it was going to be a floppy mess with no support but it hugs all the right places. I have the pillow case on it and two height adjusters.

Onyx AeroMatrix™ Pillow

The pillow is very comfortable and supportive. First pillow i haven't had to stick my hand under my head. The only problem im finding is the pillow is starting to stain the pillowcase. Thats very alarming and would like that addressed asap.

Onyx AeroMatrix™ Pillow

I'm sleeping okay so far without an increase in neck pain. I ordered the pillow, a cover, and the 2 inserts. The inserts are a waste of time as they are so thin they don't make a noticeable difference and are so flimsy they move around and don't stay on the bottom of the pillow. In frustration, I've removed them and they will probably be thrown away.

Onyx AeroMatrix™ Pillow

It's comfortable and cooling, though I didn’t expect it to be heavy. I sleep well on it and don't need to flip it. Overall, a very good purchase.
