Why Sidewell
Small pillow, big difference
-
Keeps knees apart
Stops your knees pressing together, so your top leg stays level and your lower back can relax.
-
Eases hip pressure
The contoured shape cradles your knees and keeps your hips level, not twisted.
-
Stays put all night
The leg strap keeps the pillow in place as you shift, so your alignment holds until morning.
-
Wake up refreshed
No more working out the stiffness each morning. Just get up and go.
Who is the Sidewell pillow for?
Anyone who sleeps on their side and wakes up stiff or sore, especially in the lower back, hips or knees. It keeps your legs stacked so your spine stays straight, and it cushions your knees so they aren’t pressed together all night. If you switch to your back during the night, it works under your knees too.
How do I clean it?
The cover unzips and comes off for easy washing.
Will it stay in place while I sleep?
Yes. The elastic leg strap keeps the pillow where you put it, even when you shift or turn in the night.
Which color should I choose?
Pick whatever suits your bedroom. Every color has the same shape, support and washable cover. Gray and Sapphire hide everyday wear best, while Blue, Sage and Pink are a softer look.
What if this isn't right for me?
Give it a few nights first, because your body may need a short adjustment to sleeping straight. If it still isn’t for you, you have 30 nights to return it for a full refund.
