6 Benefits Side Sleepers Love About the CloudAlignâĸ Pillow
Are you a side sleeper who feels stiff in the morning? Your pillow may be why.
Try Risk-Free for 30 Days
01
No More Crushed Shoulders or Numb Arms.
The side wings give your shoulder room while keeping your neck elevated at the right angle. No more bunching, pressure, or waking up with a numb arm.
02
Wake Up With Less Neck Stiffness.
The contoured center cradles your head and supports your neck while you sleep. So youâre less likely to wake up with that stiff, âslept wrongâ feeling.
03
Keep Your Spine Aligned While You Sleep.
The contour design and supportive lift side were made with chiropractors to keep your head, neck, and spine in a more neutral position while you sleep.
04
Cloud-Like Softness. Real Support.
CloudSoftâĸ slow-rebound memory foam gently cradles your head without sacrificing the support underneath. Soft enough to sink into, supportive enough to stay comfortable all night.
05
Keeps Its Shape. Never Needs Fluffing.
CloudSoftâĸ memory foam quickly bounces back to its original shape instead of flattening under your head. The loft you start with is the loft you wake up with â and it stays that way night after night.

Two heights in one. Flip between 3.5â and 4.3â to find the loft that feels right for you. One side is softer and lower. The other gives you more lift.

How to Use
Unbox and let the foam expand. It takes 24 to 72 hours to reach full loft.
Pick a side. The 3.5â soft side works for nasal pillows and nasal masks. The 4.3â lift side gives full-face masks more chin clearance. Flip whenever you want.
Get Comfortable. Get on your side with your head between the raised wings in the central cradle. Your shoulder drops into the lower zone.
First few nights. Most people need 3 to 5 nights for their body to adjust. Donât judge it on night one.

FAQ
What makes CloudAlignâĸ different for side sleepers?
The side wings give your shoulder room while the contour design keeps your head and neck supported. Your head rests between the raised wings and your shoulder drops into the lower zone.
Which side should I sleep on?
Try the 3.5â soft side for a lower, gentler feel or the 4.3â lift side for more height and support. Flip the pillow to switch.
How do I position my head on the pillow?
Get on your side with your head between the raised wings in the central cradle. Your shoulder drops into the lower zone.
Will it flatten over time?
No. CloudSoftâĸ memory foam holds its shape and loft instead of flattening under your head.
How long until I notice a difference?
Give it 3 to 5 nights. The foam takes 24 to 72 hours to fully expand, and your body may need a few nights to adjust.
Will I stay cool while I sleep?
Yes. CloudCoolâĸ cooling fabric gives you a cool-to-the-touch feel, while built-in airflow channels help keep the pillow cool through the night.

Is it safe for sensitive skin?
Yes. The OEKO-TEXÂŽ certified cover is tested against more than 1,000 harmful substances.
Is the pillow machine washable?
The foam isnât machine washable and doesnât need to be. The pillowcase is fully machine washable and dryer safe.
Does the foam smell?
A slight ânew foamâ scent is normal at first. It fades in 24 to 72 hours. Air it out in a ventilated room to speed it up.
Do I need to fluff or adjust it during the night?
No. CloudSoftâĸ memory foam is shape-retaining, so the loft you start with is the loft you wake up with.
