The AlignaFit Orthopaedic Knee Pillow takes the pressure off your hips and lower back at night, so you stop waking up with that nagging ache that started after years of sleeping on your side.

Side sleeping is the most common sleep position, and the most common cause of hip and lower-back pain you didn't realise was coming from your sleep. When your top leg falls across your bottom leg, your spine twists, your hip rotates, and your lower back compensates all night.

How the AlignaFit Knee Pillow fixes that

  • Hourglass contour. Slots between your knees and stays in place, no more kicking it out by 2am.
  • High-density memory foam. Holds shape all night without flattening (cheap pillows compress in the first hour).
  • Removable washable cover. Hypoallergenic, breathable, Australian-climate friendly.
  • Designed for adult side sleepers. Works for petite to taller frames, the contour adapts to leg width.
  • Also useful for back pain recovery, pregnancy, and post-surgery hip alignment.

Many customers find their morning hip and lower back stiffness noticeably reduced within 1 to 2 weeks. Some take longer if the underlying posture issue has been building for years.

What's included: 1× AlignaFit Orthopaedic Knee Pillow with removable washable cover.

Trusted by 5,000+ Australians. Free AU shipping. 30-day sleep guarantee.

If your daytime lower back pain is also a problem, see the AlignaFit Lower Back Brace. Complete your sleep alignment with the AlignaNeck pillow.

How to Use the AlignaFit Knee Pillow

Three steps to a side-sleeping position that doesn’t leave you sore in the morning.

1

Roll Onto Your Side

Lie on your preferred side with your knees gently bent. Don’t over-curl — keep your spine long.

2

Slot the Pillow Between Your Knees

Position the contour so your top knee rests in the dip. Your top leg should sit roughly hip-width above your bottom leg.

3

Settle In and Sleep

Your hips, pelvis and lower spine should now be in a neutral line. Most users feel the difference within the first night.

Wash the cover weekly: zip off, cold machine wash, air dry flat. The foam core does not need washing.

    Why a Pillow Between Your Knees Helps

    Side sleeping is the most common sleep position — and the most common cause of overnight hip and lower-back pain. When your top leg falls across your bottom leg, your spine twists, your hip rotates, and your lower back compensates all night. The AlignaFit Knee Pillow holds your knees hip-width apart, keeping your spine in a neutral line so you wake up without the ache.

    Frequently Asked Questions

    Where exactly does the AlignaFit Knee Pillow go?
    Between your knees, with your top knee resting in the contour dip. The goal is to keep your top leg roughly hip-width above your bottom leg so your spine and pelvis stay in a neutral line.
    Is it suitable for back sleepers?
    It’s designed for side sleepers, but back sleepers can place it under their knees to take pressure off the lower back. Either way, it supports the natural curve of your spine.
    How do I clean the cover?
    The cover is removable and machine-washable. Cold water, gentle cycle, mild detergent. Air-dry flat. Don’t wash the memory foam core — spot-clean only.
    Will it work for taller or shorter people?
    Yes. The hourglass contour adapts to petite and taller frames. The pillow sits between the knees regardless of leg length, so the support stays consistent.
    How long until I notice a difference?
    Most customers feel hip and lower-back relief on the first night. Morning stiffness typically reduces noticeably within 1–2 weeks of consistent use. Long-standing posture issues may take longer.
    What if I don’t sleep better with it?
    AlignaFit offers a 30-day sleep guarantee. If it’s not right for you, reach out and our Australian-based team will sort it — refund or replacement.
