A knee pillow for side sleepers can help keep your hips, pelvis and lower back properly aligned while you sleep. Simply place the Sloomio Memory Foam Knee Pillow between your knees so they stay apart, reducing pressure and keeping your spine in a neutral position throughout the night.

The pillow is crafted from responsive memory foam that moulds to the shape of your legs before gently returning to its original form. An adjustable strap holds it firmly in place all night long – even if you shift position. The breathable cover zips off and is fully machine washable.

Who is it for?

  • For side sleepers who experience pressure on their knees or tension in their hips.
  • For anyone looking for an ergonomic sleep pillow that stays put throughout the night.
  • For those who want a more comfortable night's sleep without overhauling their entire sleep routine.

Frequently asked questions

What does a knee pillow for side sleepers actually do?

A knee pillow for side sleepers sits between your knees while you lie on your side. This keeps your knees separated, which can help maintain proper alignment in your hips and lower back. The Sloomio pillow features contoured cutouts that cradle each knee for a stable, comfortable fit.

Will the knee pillow stay in place all night?

Yes – the pillow comes with an adjustable strap that wraps around your thigh. Fasten it snugly and the pillow stays put even if you change position during the night, so you can sleep without thinking about it.

How big is the Sloomio knee pillow?

The pillow measures approximately 24 × 22 × 13 cm – compact enough to sit comfortably between your knees without feeling bulky or getting in the way.

Can I return the knee pillow if it's not right for me?

Absolutely. Sloomio offers a 90-night trial period. If you're not happy, simply send an email to [email protected] and you'll receive a full refund – no hassle, no questions asked.
