Sleep Without Pain, Wake Up Refreshed, and Enjoy Better Days

When did you last get out of bed without an ache in your hip or lower back? If you can't remember, you're far from alone.

When you sleep on your side, your top leg slowly drops toward the mattress. That pulls on your lower back, twists your hips and presses your knees together, so you wake up stiff and sore. Night after night, it can turn into constant lower back pain, sciatica that shoots down your leg, and aching joints that stay with you all day.

X-ray style view of a woman sleeping on her side: without Klyvexo her top knee drops, her hips roll forward and her lower back twists; with the Klyvexo pillow between her knees, her knees stay stacked, her hips level and her spine straight.

There's a simple fix. Slip the Klyvexo™ Knee Pillow between your knees: it holds your legs in line, takes the pressure off your back and hips, and keeps your sciatic nerve from being squeezed.

Klyvexo™ helps protect you against:

  • Broken sleep from hip pain
  • Waking up stiff with achy joints
  • Sciatica pain and pinched nerves
  • Spine misalignment and pressure
  • Sore knees rubbing bone on bone

Relieve Hip Pain & Sciatica While You Sleep

Physical therapists and doctors point to one common cause of hip pain and sciatica in side sleepers: sleeping without the right support between the legs. Without it, your spine twists out of line and your back and hips stay misaligned all night.

Slipping the Klyvexo™ Knee Pillow between your knees works on that root cause. Its contoured shape keeps your knees, hips and spine lined up, and its soft strap holds it in place all night, so your body can rest, recover and wake up feeling better.

Designed Around What Health Experts Recommend

Physical therapists, chiropractors and doctors have long advised side sleepers with hip, back or knee pain to sleep with a pillow between their knees. The Klyvexo™ Knee Pillow was designed around that exact advice, then given a soft strap so the position holds all night.

Side sleepers who use a knee pillow commonly report less hip, lower back and leg discomfort, deeper sleep and easier mornings.

Frequently Asked Questions

Is this pillow good for sciatica and back pain?

Yes. A pillow between the knees is one of the most common recommendations for side sleepers with sciatica and lower back pain. Klyvexo holds your hips, spine and legs in line all night, which takes pressure off your lower back and the sciatic nerve.

Will it really stay between my knees when I roll over?

That's what the strap is for. It loops around your top leg just above the knee, so the pillow moves with your legs, not the sheets. When you turn over, it turns with you instead of staying behind. Give yourself a night or two to find the strap position that feels right.

Is the firmness right for me?

The core is [TO CONFIRM: material, e.g. memory foam, and density]. It's designed to support your top knee [TO CONFIRM: firmness/height retention]. If the feel isn't right for you, you have 60 nights to send it back.

Can any sleeper use this pillow?

It's designed for side sleepers. On your back, slide it under your knees for a gentle bend. If you sleep on your stomach, a knee pillow isn't the right tool, and we'd rather tell you now.

Will I overheat with this pillow?

Klyvexo only touches the inside of your knees and lower thighs, not your whole body like a body pillow. The open center means less pillow against your skin, and the cover is a soft knit [TO CONFIRM: fabric composition]. It's a lot less pillow than you're used to wrapping around.

How long does this pillow last?

It's made to keep its shape night after night [TO CONFIRM: material and expected lifespan from the supplier]. The zip-off cover can be washed whenever you like, so it stays fresh.

Is the cover washable?

Unzip the cover, slide it off and machine-wash it [TO CONFIRM: e.g. cold, gentle cycle, air dry]. Keep the inner core out of the washer and just let it air out [TO CONFIRM: core material + care]. The dark heather gray hides everyday wear between washes.

Is this pillow travel-friendly?

Yes. It's compact enough to pack in a suitcase or a carry-on, so you can keep sleeping aligned in hotels and guest rooms.

Will I get used to it quickly?

Give it a few nights. If you've slept twisted for years, sleeping aligned can feel strange at first. Try it a little higher or lower on your thighs until it feels right. Judge it by your mornings, not by the first night.

When will my order arrive?

Orders are processed in 1–3 business days. Once your order ships, US delivery takes 7–12 business days. Shipping is tracked and insured: $2.99 on orders under $50, FREE on orders of $50 or more. You'll get a tracking number by email.

What if the pillow doesn't suit me?

Then you don't keep it. You have 60 nights from delivery to decide. Email us at support@klyvexo.com and we'll walk you through the return and refund. [TO CONFIRM: return conditions]
