5 reasons side sleepers wake up sore, and the one pillow that fixes all 5
If you’ve bought pillow after pillow and still wake up with a stiff neck, a numb arm or a sore shoulder, it probably isn’t you. Here’s what’s really going on under your head.
5 minute read | Written by the Avena Sleep Team
Your pillow is too low for the width of your shoulders
On your side, there’s a wide gap between your ear and the mattress. A regular pillow squashes down, your head drops toward the bed, and your neck spends eight hours bent sideways. You wake up stiff and blame your age.
The Cloud Pillow has a tall end made for side sleeping. It fills that gap, so your head stays level with your spine all night. Roll onto your back? Turn it around to the low end.
“I didn’t know my head was hanging all night”
“Broad shoulders, side sleeper, and every pillow I owned sank. The first morning on the tall end I turned my head to check for the stiffness. It wasn’t there.”
It feels fine at bedtime and gives up by 2am
Fluffy pillows squash under the weight of your head. By the middle of the night it’s half the height you started with, so you wake up folding it in half, stacking a second one, or punching it back into shape.
The Cloud Pillow is slow-rebound memory foam. It gives under your head, then holds its height until morning, so there’s nothing to fold, stack or re-fluff at 2am.

Side sleepers prop up a low pillow with an arm underneath it. Your arm carries the weight of your head for hours, and you wake up with pins and needles, shaking your hand until the feeling comes back.
The Cloud Pillow is already tall enough, and it has an arm notch on each side, so your arm rests in the notch instead of holding up your head.
“My arm finally stopped going numb”
“I’ve slept with my hand under my pillow my whole life and woke up with a dead arm most nights. Now it just sits in the notch. I didn’t even have to think about it.”
The neck pillow you bought felt like sleeping on a brick
So you tried a contour pillow. It was hard, too tall, or the wrong shape the moment you rolled over. You gave it a few nights, then it went in the closet with all the others.
The Cloud Pillow is medium-firm foam under a soft knit cover. Your head sinks in a little, then it’s held, and the rounded edges mean no hard corner pressing into your cheek.

You’ve seen why side sleepers wake up sore. Now see the pillow built to fix all five.
One bad night turns into three bad days
You wake up with a kink in your neck. By lunch you can’t turn your head to reverse the car, and it gets worse over the next two or three days. Just as it eases, another bad night starts it all again.
The Cloud Pillow keeps your neck level from the moment you lie down. It fits, sleep comes quicker, and you wake up rested, without the morning kink.
“Three days of neck pain, every single week”
“I honestly thought that was just my life now. Two weeks on this pillow and I realised I hadn’t reached for the heat pack once.”
Your neck didn’t get this sore in one night.
Here’s what your first two weeks look like:
It holds your head the moment you lie down
Lay your head down and it just clicks. Your head and neck settle into the shape and stay supported all night.
The morning kink starts to fade
No more waking up with a kink in your neck that gets worse over the next two or three days. Your neck stays level all night, which helps stop the kink before it starts.
Your body settles in
You stop reaching for your numb arm at 2am. You stop folding the pillow in half.
Falling asleep gets easier
You lie down, it fits, and sleep comes quicker. You sleep straight through and wake up rested, with no sore neck to stretch out.

Has anyone actually tried the Avena Cloud Pillow? I wake up every single morning with a stiff neck and I’ve bought like 6 pillows this year. Honest answers please 🙏
Melissa Grant · 3d
Stacy Moreno Yes! Got it in June. I’m a side sleeper and I was the biggest skeptic, I have a closet full of pillows. Put my head down the first night and it just fit. The stiff neck just stopped. I don’t fold my pillow in half any more lol
Stacy Moreno · 3d
Melissa Grant is it too hard? that’s my biggest worry
Melissa Grant · 2d
Stacy Moreno not at all. It gives under your head then holds. Mine was flat by 2am, this one is the same in the morning.
Donna Whitfield · 2d
Not gonna lie I rolled my eyes when my sister sent me this 😂 I have a closet full of pillows that went flat. This one hasn’t moved in 3 months and my neck feels better in the morning.
Kara Lindqvist · 2d
Donna Whitfield same here. We both use a different end, it works for both of us.
Dave Huang · 1d
Bought it for my wife after years of her waking up with neck pain. She says the little notch on the side is where her arm goes now, instead of under the pillow. Worth it for that alone honestly.

I was cautious because I’ve wasted so much on pillows, but the shape makes sense once you lie on it. Your head stays level instead of dropping down. Been on it 10 weeks, no complaints.

Renee Watkins thank you, that’s really reassuring. Ordering the 2 pack tonight

Week 3 here. I sleep straight through now, which I did NOT expect. Throwing out my old pillows this weekend 🤞
Your neck needs a pillow that holds all night.
Not one you fold in half at 2am.
The Cloud Pillow is shaped for side sleeping and made to keep its height until morning.

| At 2am | Holds its height | Half the height | Holds its shape |
| Your arm | Notch on each side | Under the pillow | Under the pillow |
| Back and side | Two heights, turn it | One height | Usually one position |
| Feel | Medium-firm, soft cover | Soft | Often hard |
