Three layers. One job: the loft your neck actually needs. Add or remove fill until it fits. Free extra fill, forever.
Side sleepers need a higher loft to fill the shoulder gap. Back sleepers need a medium loft to keep the neck neutral. Stomach sleepers need almost nothing. Most pillows pick one height and force your neck to adapt. Stratum adapts to you.


Shredded visco-elastic memory foam at 45–50 kg/m³ density. Dense enough to cradle your neck in one shape all night — not dense enough to wake up with a crick in your jaw.



Unzip the outer cover. Open the muslin lining underneath. Add a handful of fill or take one out. Do it again next week. Do it again after a year, when your shoulders feel different.
First extra fill bag ships with your order. Every refill after is free.


No dramatic before-and-after. No transformation claim. Just a pillow that lets your neck meet the morning quietly.
Ordered after my chiropractor said to stop buying pillows. First morning in eight years I woke up without the headache. Four inches of fill was my number. Took two nights to find it.
Added the extra fill bag twice before I got the loft right. No more numb arm in the morning. The muslin inner lining holds everything together overnight. Most pillows in this category skip that.
PT said most pillows are too thick for post-fusion cervical recovery. Stratum goes thin enough. I pulled about half the fill out. First pillow I've kept past the trial in three years.
Thought 'adjustable' was a gimmick. Then my husband stole mine. We have two now and neither of us will give them up.
Paid more at the sleep store for a pillow that gave me five mornings of neck pain. The extra fill bag is the part that matters. They really do ship it free when you ask.
I run hot. Returned two memory foam pillows before for being warm. This one actually stays cool on the back side. Not arctic. But not a hot brick either.
Best pillow I've owned. That's the review.
Works.
Started with too much fill. Pulled a handful out every night until the chin tip stopped. It's not a one day adjustment. Once I got there, it stayed. Taking a star because the first few nights were rough.
Back sleeper. My old pillow pushed my chin into my chest all night. Stratum at 3 inches of fill keeps my head neutral. Ten nights in and the morning stiffness is gone.
I opened mine up to see how it's built. There's an actual cotton liner inside holding the fill, not just foam rattling around in the cover. You can tell they spent the extra dollar. Fill hasn't migrated in four months.
Solid.
Smelled like foam for about 36 hours out of the box. Aired it out on the porch for an afternoon and it was fine. Has been perfect since. No regrets.
Bought one for me. Then one for my wife. Her sister has one now. That's the review.
Woke up without reaching for the Advil. First time in a long time.
Had a rotator cuff repair last year. Could not get comfortable on any pillow. Added fill until my head stayed level with my spine. First pillow that doesn't make me adjust my shoulder all night.
Bought it for me. She made fun of the price. She's now sleeping on mine and I'm waiting on a second shipment. I accept this outcome.
Coop, Layla, Saybrook, Tempur, the blue one from Amazon, two my PT recommended, and one my wife's friend sews. This is the one I've kept past 30 days.
Neck pain gone. Will buy another.
No QR code. No pamphlet. No influencer postcard asking me to tag anyone. Just the pillow and a small bag of extra fill. Thank you.
It's better than my old pillow. I don't think it fixed my neck. I kept it because the return felt like too much hassle. If you're expecting the pain to vanish, keep expectations in check.
My chiro saw it and nodded. That's about the highest praise he gives any product. Two months in, my appointments are down to once a month.
Seven years of waking up stiff. Took about a week of adding and removing fill to dial it in. I sleep through the night now.
Six days to arrive. Everyone else delivers in three. Otherwise, great pillow.
He wrote the name down. Usually it's the other way around.
Fifteen years of morning migraines. Changed the pillow. Migraines stopped. I had accepted the wrong hypothesis for a long time.
Fibromyalgia. Flare-ups are less frequent since switching. Not a cure. But the mornings are softer.
Stage three cervical spondylosis. My ortho suggested the exact fill and loft control this pillow offers. He was right.
Bought one. Then one for the guest room. Then one for my daughter. She has arthritis too.
My neck hurt so much I dreaded sleep. Now I look forward to it. Seems like a small thing. It's not.
First week was too firm. Loosened up by week three. Fine now.
Every other 'adjustable' pillow is a gimmick. The fill range on this one is useful. 3 to 6 inches covers everyone I know.
TMJ pain. Started pulling fill. After two weeks my jaw stopped clicking in the morning. No promises but it worked for me.
The knots between my shoulder blades were daily. I can go a week now without needing to stretch them out.
I was going weekly for neck tension. Now I go twice a month. The pillow is the variable that changed.
CPAP user with cervical issues. The low loft works with the mask. First pillow that doesn't fight the equipment.
Followed the care instructions. Cover shrunk after two cycles. Now tight on the pillow. Customer service offered a replacement cover but I wish it hadn't happened in the first place.
The nerve on the right side of my neck used to go numb. Adjusted fill to the lowest comfortable setting. Haven't felt the tingle in six weeks.
He was right. This is the one I chose. Back of the head stays level, cervical curve supported.
6 foot 5, 260 pounds, broad across the shoulders. Loaded the extra fill bag in and added more. Finally a pillow that does not collapse under my head.
Measured my shoulder width finally. 21 inches. Added fill until my head stayed in line. That was the fix.
Used to wake up with pins and needles in my bottom arm. Not anymore. Worth every penny.
Site said 'a few nights to adjust.' Took me closer to two weeks. Got there. Keeping it.
Used to flip ten times a night. Now I fall asleep on my right side and wake up on my right side. That's the rubric.
Loaded all the extra fill in. Perfect for my frame.
Tall, big-shouldered, side sleeper. This is the first pillow in a decade that supports my head without a second pillow shoved under it.
First pillow that keeps up with my shoulder width. Lower back issues also improved, which I did not expect.
College swimmer, big traps. Stratum has the loft range I needed. 5.5 inches is my number.
Aired out in 48 hours. Four stars because it did not vanish immediately. But it did vanish.
He had been complaining about his pillow for a decade. Mine converted him.
Adjusted high enough that my shoulder wasn't bearing weight. The impingement pain stopped waking me up.
Finally.
5 inches is my number. Got there in three nights.
High loft held up. No complaints about loft loss after two months either.
Aired it out for a week. Still smelled like chemicals. Returned it inside the trial window and they did pay the shipping back, so that part was easy. Not for me.
Nobody talks about this. Broad-shouldered women need loft too. 4 inches, sorted.
Pregnancy forced the switch. This pillow followed me to the new position.
Trying to stop stomach sleeping because of neck pain. Low loft on Stratum made the transition bearable.
Rolled to my other side. The pillow rolled with me. Still worked.
I used to shove a second pillow under my arm for height. Don't need it now. Shorter bed-making routine.
Surgeon approved. Low loft. I pulled fill weekly for the first month.
Post-accident neck. Adjustable fill was the only way to find what worked. Still testing new heights.
Could not get comfortable post-op. Kept adjusting for two weeks. Got there.
Bamboo cover is nice. Would love a true cooling side though.
Low-loft setting. Minimal pressure on the cervical curve. Second month, no numbness.
Discectomy and fusion last May. This is my pillow now. I travel with it.
I don't disagree with $99.99, I just wish it was $79.
Used to sleep in the recliner. Moved back to the bed six weeks ago. Pillow was the difference.
I slept propped. Stratum at medium fill plus a regular pillow. Worked.
Works. I'm not sure it's three times better than a $30 pillow from Costco. Maybe 1.5 times. Keeping it though.
Thin setting. Pulled two-thirds of the fill out. Perfect for post-op.
The abduction sling plus Stratum got me through recovery sleep. Stratum stays.
Wish there were a second zipper on the opposite end. Would make adjusting faster.
Construction is legitimate. Real muslin liner, proper zipper, actual memory foam and not polyester fill pretending. The photos on the site are accurate.
Not plastic-tooth junk. It'll last. I appreciate the detail.
Dense enough to support, shredded enough to be moldable. They got the balance right.
Machine wash cold, hang dry. No pilling after three cycles.
Chemically sensitive. I check certifications. Stratum met the bar.
Outer cover slides around a bit. Not a dealbreaker.
First pillow I've seen nail the inner-liner concept. The fill stays homogeneous overnight. The cover decouples for washing.
No clumps, no cold spots, no lumps at 3 months.
Five. I returned five other pillows. This is the one I kept. My wife is considering a second.
Coop was my prior favorite. Stratum is better because the inner liner keeps the fill from bunching.
Despite the liner, my fill clumps to one side. I flip it. It keeps migrating. Disappointed.
Tried Saybrook first. Sent it back inside the trial. Bought Stratum. Kept it.
Bear was OK. Parallel was too firm. Stratum got the loft range right.
Dosaze was fine. The return was easy. But I kept Stratum because the extra fill bag actually made a difference.
I set a reminder to return it at day 95 just in case. Didn't need to.
Two other adjustable pillows went back inside the trial. Stratum stays.
Last pillow of 2025. Probably last pillow of the decade.
Came stuffed to the gills. Pulled about 25% of the fill out to start.
I emailed a hotel to ask what pillow they used. Their answer was worse than Stratum. Kept Stratum.
I trust a brand more when they don't oversell. Copy said 'adjustable.' Pillow is adjustable. Bar cleared.
I don't want a pillow subscription. This is a purchase. It's a pillow. Thank you.
He has opinions. Bought one for himself after two weeks with mine.
First for us. Then for the guest room. The in-laws have Opinions.
Even with most of the fill pulled out, felt firm to me. Returning.
Kids wanted them too. Cheaper than therapy for the teenager with neck pain.
He came for Thanksgiving. Bought one Monday.
Comfortable. Does not change my life. Kept it because I don't want to pack it up.
My 14 year old has been sleeping well ever since.
16 year old with football-size shoulders and neck pain. Adjusted fill to his build. No more morning complaints.
Extra fill bag could be bigger. Had to write in for more. They sent it free.
She bought one for when I visit. I never gave it back. Bought her a new one.
Can't blame her.
Commuted every week for work and slept on terrible hotel pillows. Stratum is better than any hotel pillow I've used.
Menopausal. I was waking up drenched. Flipping the pillow gave me 30 more minutes before I had to flip again. That is meaningful.
Both sides cool. Ten years of Tempurpedic and I never flipped it. Stratum is actually cool on the other side.
Two months in, I found small foam dust when I opened the liner. Quality issue. Warranty process is in motion. Will update if they come through.
I don't think this pillow would stay cool sandwiched between two space heaters. But in actual Georgia summers, it works.
I know I am one. This pillow passed the test.
Added. Added again. Perfect. The bag was bigger than I expected.
Kept going until my chin stopped tilting down. Worth the adjustment period.
Took one week to find it. I've kept it there since.
Helped my neck a little. Not a lot. Keeping it.
Measured, then filled. No adjustments needed after week 1.
I thought I was a side sleeper. Partner clarified I'm a back sleeper. 3 inches of fill, and I stopped snoring as a bonus.
8 nights of small adjustments. Now set. Not changing it.
No QR codes. No 'Follow us on Instagram.' No 'Tell a friend for $5 off.' Just a pillow. Refreshing.
Emailed with a question. Got a reply in 38 minutes. From a human named Maya. Thanks Maya.
Loft dropped about 10% in the first month. Added some fill back. Fine now.
I did return my first one because I bought the wrong loft expectation. They paid return shipping, refunded in 3 days, and I bought a second one.
Wrote in asking for more fill. Arrived on my porch a week later. No questions, no invoice.
I liked that. Two paragraphs. No life advice.
I asked because I wanted to over-stuff it. They sent another bag. Thank you.
Not really a complaint. But it's heavy. Full-size isn't a carry-on pillow.
10 out of 10.
Wife approved.
Husband approved.
Five stars.
The pillow is OK. The free refill bag is the best part. I know that's a weird review.
No notes.
Top-shelf pillow.
Better than my old pillow. Not a total fix. That is fair.
I bought my mom one. She called to thank me.
Yes, I am that person. Packed it down into my luggage. Worth the packing Tetris.
Great pillow, full stop.
10 year old. Used to wake up three times. Not anymore. I don't understand why but I'll take it.
Recommended by my orthopedic surgeon's wife, who also has neck issues. Took her advice.
He thinks it's 5 stars. I think it's 4. Averaging out.
Neck pain, back pain, all better.
Fill was more firm than I expected. Once dialed in, fine.
Most pillows say adjustable. You open the zipper, see that it's shredded cotton or polyfill, and return them. This one delivered on what the copy promised.

A Stratum for your side of the bed. A Stratum for theirs. Save $30 either way.

A natural cardboard box. One Stratum. One muslin bag of extra fill. One care card.
That's everything. No pamphlets. No QR codes. You bought a pillow. We sent you a pillow.
It depends on your shoulder width and sleep position. Side sleepers: start at 5–6 inches of fill. Back sleepers: 3–4 inches. Stomach sleepers: as thin as you can get without removing the lining (about 2 inches).
The outer cover comes off and goes in the washing machine. The inner muslin lining stays with the fill — it's what holds the shredded foam together as one pillow. Most pillows in this category skip the lining to save a dollar.
No. It's a pillow, not a medical device. If a pillow brand says they're FDA-cleared, they're making it up.
No. Return it inside 100 nights for any reason. We pay the shipping. Keep the extra fill bag either way — it's already yours.
Not on a label. We only say that when we're quoting a named, partnered chiropractor.
Free, 3–5 business days in the continental US. Tracking emailed the day it ships.
If it's the right pillow, you'll know by the second week. If it's not, we pay the return. Either way, the extra fill bag is yours to keep.
