Engineered for back pain relief

Ever tried a standard pillow between your knees to tackle hip or back pain? Then you know it doesn’t work. Regular pillows aren't designed for targeted joint support. They can't maintain the correct distance, meaning you wake up in pain with the pillow tossed aside.

The Groove X Pillow is a specialist hip alignment pillow. Crafted with an ergonomic groove, it cradles your thighs and keeps them in their natural position. The comfy elasticated loop wraps around one leg, ensuring the pillow stays secure all night long providing relief from back and hip pain.

Supreme support, coolness, and comfort

The pillow is crafted from the same high-quality materials as our best-selling Original Groove® Pillow.

Made with bamboo-infused memory foam, it boasts natural anti-bacterial properties to keep it fresh. With a 50D "Goldilocks" density, it's the perfect balance between support and softness - just right! Wrapped in a cozy jersey lining and Luxury quilted cover, it's soft to the touch and easily machine-washable.

Try it completely risk-free for 100 nights

We have 100% confidence in our pillow and its power to alleviate lower back, hip, and thigh pain. With our unbeatable 100-night sleep guarantee, if the Groove® X Pillow doesn't meet your expectations, we'll refund the full price. So go ahead, put it to the test, and experience the difference for yourself.

Product Information

Material

The Groove® X Pillow is created using bamboo charcoal infused memory foam, with a jersey lining, soft luxury cover, and a recyclable zipper.

Size

Dimensions: 10.2 in × 6.3 in × 8.1 in

How do I use it?

Without any knee support, the top hip swings over the bottom to rest on the bed, and the spine is taken out of alignment. This is a prime cause of morning back pain.

Place the Groove® X Pillow between your thighs at the top of your knees, with the loop around one of your legs. This way your spine is aligned, and the pillow stays in place even if you decide to swap sides.

You can also place the X-pillow under one knee whilst sleeping on your back to alleviate any knee pain.

How does it work?

The key to sleeping with proper posture is to keep your spine in a more natural, neutral position.

The Groove® X Pillow sits comfortably between the knees, providing firm support to the knees and lower back. This reduces stiffness, aches, and pain by correctly aligning your hips and pelvis as you sleep.

The pillow is suitable for sleepers with arthritis, knee pain, sciatica, and lower back pain.

Product Care

To wash the cover, simply remove it and wash it with your whites in the washing machine in 30 degrees.

Do not wash the pillow itself, as this will ruin the memory foam.

Frequently Asked Questions

Does it work for back and side sleepers?

Yes. The Groove® X Pillow works best for side sleepers, cradled between the knees during sleep. However, back sleepers who want additional support can rest it under their knees at night.

Won’t it fall out as soon as I fall asleep?

No! We’ve designed the Groove® X Pillow with a comfy strap that wraps around your legs as you sleep. This holds the pillow firmly in place, even if you toss and turn.

How should I use this pillow to achieve the best results?

It’s easy. Before sleep, slip it between your thighs at the top of your knees, with the loop around one leg. The strap ensures the pillow remains securely in place, even when switching sides at night. You can also place the pillow under one knee while sleeping on your back to alleviate knee pain.

What are the dimensions of the Groove® X Pillow?

The dimensions are: 10.2 in × 6.3 in × 8.1 in

Can the pillow cover be removed and washed?

Of course! The Groove® X Pillow comes with a removable cover that's machine-washable, so you can keep your pillow clean and fresh for a long time. Just remember not to wash the actual pillow, as it can damage the foam.

How long does the memory foam last, and is there a warranty?

High-quality memory foam pillows like the Groove® can last for several years with proper care. The Groove® X Pillow also comes with a 2-year warranty, covering manufacturing defects and other quality-related issues.

    Hugely helped my lower back pain

    I’m 30 and am on my feet a lot and do quite a bit of exercise and have been experiencing an ache in my lower back for the past year. Thought I’d try the groove lower back pillow as I already have their neck pillow and it’s been really helpful. I sleep on my side a lot and with the pillow I can feel the relief in my back and less aching during the day. Would really recommend it.

    Amazing pillow !

    I ordered 2 of these for me and my husband . I was prepared to be disappointed as every pillow I have purchased before has never lived up to their promises . However this one is fantastic !

    My husband and I both love them ,they are very comfortable, stay in place all night and have relieved joint pains from side sleeping . Highly recommend.

    Thank you so much 😊

    Great knee and hip pain reliever

    Just what I needed. Much more convenient and comfier than pulling excess quilt between my knees. Hips and knees feel much better as a result.

    Helps lower back

    I wasn’t sure how much the knee pillow would help a long-standing issue with my lower back, but I have been delighted with the difference it has made.

    When I use it, I no longer wake with a stiff, sore back.

    I tried not using it to see what would happen, and the sore back returned.

    It seems to align your hips in such a way that the lower back can stay relaxed.

    I’m very glad I bought it, and would recommend it to anyone suffering with a sore back after a night’s sleep.
