The Problem
Side sleeping puts your knees, hips, and lower back to work all night
If you sleep on your side, your top knee can press straight down into the bottom one for hours. That's the ache you feel in your hip, the stiffness in your lower back, or the pressure on your knees when you wake up and try to roll over. A regular pillow between your legs often slides out of place, flattens out, or just doesn't sit right. This memory foam knee pillow is shaped specifically to sit between your knees and hold that position steady, so you're not readjusting it every time you shift.
How It Works
Shaped to cradle your knees, not just sit between them
Most people just grab a spare bed pillow, but a bed pillow isn't built for the shape of your legs — it's too big, too flat, and it slides. This pillow has a compact, contoured triangular shape with a center cutout that lines up with your knees, so the memory foam holds its form instead of compressing flat like loose filling can.
The Detail That Matters
An elastic strap keeps it from sliding away mid-sleep
A loose pillow between your knees is fine — until you move. The elastic strap wraps around your leg and moves with you, so the pillow stays in position through the night instead of ending up on the floor or slipping down toward your feet.
Materials & Care
Memory foam inside, a removable cover on the outside
The pillow core is memory foam that shapes itself to your legs and holds that shape overnight instead of packing down. The soft knit cover unzips fully so you can take it off and wash it, which matters for something you use every night against your skin.

FAQ
Common questions
What is the pillow made of?
The core is memory foam, wrapped in a soft, removable knit fabric cover.
Can I wash the cover?
Yes. The cover unzips off the memory foam core so you can wash it separately.
How do I use it?
Lie on your side and place the pillow between your knees, then wrap the elastic strap around your top leg so it stays in position as you move.
Does the strap fit any leg size?
The elastic strap stretches to wrap comfortably around the leg and hold the pillow in place through the night.
Is this a medical device?
No. It's an ergonomic sleep support designed for comfort, not a medical treatment device.
Memory foam knee pillow with an elastic strap that keeps it in place between your knees all night. The contoured shape holds up better than a regular pillow, and the cover unzips off for easy washing.
