You've been sleeping wrong for years. This fixes it tonight.
When your knees have nothing between them, your top leg pulls your hip forward and your spine rotates out of alignment. You don't feel it happening — but you feel the result every morning. The contoured shape holds your legs exactly where they need to be all night, so your hips, knees and lower back finally get to rest the way they were meant to.
Soft enough to forget it's there. Supportive enough to feel the difference.
Hypoallergenic, odourless, and gentle against skin — the knit cover feels like it belongs in your bed from night one. No breaking-in period, no adjustment phase. Just place it between your knees and let the memory foam do the rest.

Works Your Way
Most people start on their side and wake up on their back. The knee pillow works in both — between your knees for side sleeping, under your thighs for back sleeping, beneath your calves when your legs need elevation. You don't have to sleep perfectly. It adapts to however you actually sleep.
Built to Support, Made to Last
Most knee pillows feel great for the first two weeks — then the foam compresses and you're back to where you started. The high-density core in the Restella Knee Pillow is rated for years of nightly use. The support you feel tonight is the same support you'll feel in six months. No replacing, no readjusting, no starting over.
-
Ergonomic Contour Design
The hourglass curve follows the natural gap between your knees and calves — so the pillow sits securely without you having to hold it in place or readjust through the night.
-
Washable in Minutes
Unzip the cover, toss it in the machine at 30°C, back on in minutes. A pillow you sleep with every night needs to actually stay clean — this one makes it effortless.
-
Responsive Memory Foam
Slow-rebound foam that takes your shape within minutes and holds it until morning — so your legs stay supported whether you move once or ten times through the night.
