Every Thanksgiving, my husband and I drive eleven hours from Phoenix to see our daughter Sarah in Denver.
I love her more than anything. But I dread going.
Not the drive. Not the cold. The sleeping.
I'm a side sleeper. Always have been. But three years ago the shoulder pain started, and it's gotten worse every single year.
I always slept on my left side. Then the left shoulder got so bad I had to switch to my right.
It was probably only a matter of time before the right one went too.
Most nights I can fall asleep fine. It's staying asleep that's the problem.
I'll wake up and my shoulder is killing me. Deep, aching pain in whatever side I'm lying on.
Sometimes my arm goes completely dead. Pins and needles from the shoulder all the way down to my fingertips.
I'll flip to the other side, get comfortable for a little while, and then that shoulder starts aching too.
I haven't slept more than four hours straight in years.
On the bad nights I give up and move to the La-Z-Boy in the living room. Sitting upright is the only position that takes the weight off my shoulders.
At home, it's just another bad night. Nobody's watching. Nobody's asking if I'm okay.
At Sarah's house, I'm a guest. I don't want to be the mom who can't sleep, who's miserable all morning, who ruins Thanksgiving because she's exhausted and hurting.
THE FIRST NIGHT
We arrived around 7 PM. Hugs, dinner, catching up. By 10 I was exhausted from the drive.
I laid down on my right side around 10:30 and closed my eyes.
I woke up and looked at the clock... 6:47 AM.
I had slept through the entire night for the first time in three years.
On my side. On the same shoulder. Eight straight hours.
"You didn't get up once," my husband said. He looked confused. He'd heard me shuffle to the La-Z-Boy for years.
"Must've been the drive," I said. "I was exhausted."
But that wasn't it. Because the second morning I woke up... and realized again... I slept through the entire night.
No tossing. No flipping to the other side. No 3 AM walk to the living room.
I lifted my right arm above my head. Full range of motion. No stiffness. No catching. No pain.
That hadn't happened in three years.
THE DISCOVERY
That morning, I stripped the pillowcase off and looked at the pillow underneath.
It didn't look special. No weird contours. No fancy memory foam shape. Just a pillow.
There was a small tag hanging off the zipper.
"Nuzzle."
I'd never heard of it.
I pulled out my phone and googled it right there.
First thing that came up: Trustpilot reviews. 4.7 stars. Thousands of reviews.
I started scrolling...
WHAT MY DAUGHTER TOLD ME
I found Sarah in the kitchen.
"That pillow in the guest room," I said. "Where did you get it?"
She laughed. "I wondered if you'd notice."
Sarah's an ICU nurse. Has been for twelve years.
"You know Dr. Reeves? The orthopedic surgeon I work with?"
I shook my head.
"His wife had a total reverse shoulder replacement last year.
"After the surgery, sleeping was impossible. She's a side sleeper, same as you, and the pressure on the joint was so bad she'd be up every two hours.
"He tried every pillow, every positioning trick. Nothing worked."
"Then he found this pillow and it was a game changer. She started sleeping through the night within a week.
"He wouldn't shut up about it. Kept telling the nurses, 'If your patients have shoulder issues from side sleeping, tell them about this pillow.'
"So a bunch of us ordered them."
"Why didn't you tell me?"
"Mom, I've tried to help your shoulders for years. You've tried everything. I didn't want to push another pillow on you."
She was right. I had tried just about every cream, tincture, and pillow out there.
Back home in Phoenix, I have a closet full of different pillows that all claim to be "the best."

Coop Original Pillow

MyPillow Premium

Cervical Neck Pillow from Amazon

Tempur-Pedic Cloud

Purple Harmony Pillow

Derila Ergo Pillow

Miracle Bamboo Pillow from Costco
Not one of them solved the shoulder pain. Not one.
I really didn't have much hope left that anything would help.
WHAT MY DAUGHTER EXPLAINED TO ME
"Mom, let me show you something."
Sarah sat down next to me. She grabbed one of the old guest pillows from the closet.
"Lay on your side for a second."
I did. She pointed to the space between my neck and the mattress.
"See that gap? Between your shoulder and your neck?
"That's about four to five inches of empty space that your pillow is supposed to fill."
She pushed the old pillow under my head. My head sank. The pillow compressed. The gap was still there.
"That's what I call the pillow hole. Your pillow is too flat, too soft, or just the wrong height. So it doesn't fill that space. Your neck hangs. Your head drops."
"And when your head and neck aren't supported..."
She put her hand on my shoulder, pressing lightly downward.
"...your shoulder is left driving into the mattress. Bearing all your weight. All night."
She let that sink in.
"Eight hours of your body weight crushing into one shoulder joint.
"That's why you wake up with a dead arm. That's why the shoulder aches.
"It's not a shoulder problem, Mom. It's a pillow hole problem."
"And here's the thing. Even if you've got arthritis in the shoulder, a torn rotator cuff, whatever.
"It doesn't matter what's going on in that joint if you're driving it into the mattress for eight hours every night.
"It can't heal. It can't recover.
"You're just re-aggravating it in your sleep and wondering why nothing gets better."
That hit me.
I'd been taking Advil every morning. Trying pillow after pillow.
But the whole time, it was the gap that wasn't getting filled.
And my shoulder was paying for it every single night.
"So why doesn't any pillow fix this?"
"Because everyone's gap is different," Sarah said.
"The distance between your shoulder and your neck isn't the same as mine.
"Most pillows are one height. Your gap isn't."
She picked up the Nuzzle pillow and unzipped it.
"This is a 2-layer system. Thicker layer, thinner layer.
"You stack them to fill YOUR gap.
"Broader shoulders like you, keep both. Smaller frame, pull one out.
"That's how you find the right height. So the pillow hole actually gets filled."
"Okay, but I've had thick pillows before. They just felt like bricks."
"That's the other part."
She pressed her hand into the pillow. The surface gave way. Her hand sinking in deep, naturally.
"These are Nanocoil fibers. They're not memory foam.
"They let your head and neck settle in first, then they cradle. All night.
"So your head is supported, and that takes all the pressure off your shoulder."
She released. The pillow rebounded instantly.
"Support your head. Take the pressure off your shoulder. And it feels totally natural. That's it."
That's when I understood why nothing else had worked.
Every other pillow either left the gap open or filled it with something so rigid my shoulder got crushed underneath it.
This was the first one that filled the hole AND let my shoulder breathe.
I ORDERED TWO BEFORE WE LEFT DENVER
The pillows arrived three days after we got home.
I left both layers in, just like I'd used it at Sarah's. I naturally have broader shoulders, so I need the extra height to fill the gap between my shoulder and my neck.
My husband sleeps like a rock on anything...
But out of curiosity, he pulled the thinner layer out. Said it was perfect for him.
THAT WAS 8 WEEKS AGO
The first few nights, I figured it was wishful thinking. I've been disappointed by pillows enough times to know not to get excited.
But by the end of week one, something hit me. I hadn't woken up once to switch to the other side. Not once. I'd sleep the whole night on one shoulder and wake up fine.
After the first week, I'd say the shoulder p…
