Care Instructions

  • Cleaning the cover: Machine wash: the pillow cover is removable and can be washed in a washing machine. Use cold water and a delicate cycle with a mild detergent.
  • Hand Wash: Without removing the cover, gently wash the cushion by hand using cold water and a mild detergent to avoid damaging it.
  • Drying: Air dry the cushion cover by laying it flat or hanging it up. Do not use a tumble dryer, as high temperatures can cause shrinkage or damage to the fabric.
  • Stain removal: In case of spills or stains, clean the affected area with a damp cloth and mild detergent. Gently blot ( do not rub ) to remove the stain without damaging the fabric.
  • Do not use bleach: Avoid using bleach or harsh chemicals that may damage the polyester fabric or affect its color.
  • Ironing: If the pillowcase is creased, it can be ironed at a low temperature, but this is not usually necessary for polyester. To protect the fabric, place a cloth between the iron and the pillow.
  • Dry cleaning: Dry cleaning of polyester fabric is not usually necessary. However, if necessary, always check the care label and follow any specific instructions.
  • Storage: Store the pillow in a cool, dry place. Avoid storing it in areas with high humidity or in direct sunlight to prevent damage or discolouration. When the pillow is not in use, store it in a breathable cover or bag to protect it from dust.
  • Fluffing the pillow: To maintain its ergonomic shape, gently fluff the pillow from time to time. This will help redistribute the filling and maintain comfort for a long time.

Most nights, it ends up on the floor.

Most knee pillows are just a flat block of foam. They don't follow the shape of your legs — so within an hour they've shifted, slipped, and you've woken up to adjust them for the third time. The SideRest is shaped around the natural curve between your knees and calves. It sits where it needs to, stays where it needs to — from the moment you lie down to the moment your alarm goes off.

Better position. Better rest.

When your top knee has nothing to rest on, your whole leg pulls downward through the night. You don't notice it happening — but your hips and lower back feel it by morning. The SideRest sits between your knees and holds your legs in a neutral position so everything stays naturally aligned while you sleep.

  • Premium zipper

    Heavy-duty zip that opens and closes smoothly every time — no snagging on fabric, no catching mid-wash, no breaking after three months of nightly use.

  • Breathable mesh vent

    Mesh ventilation panel keeps air moving through the core all night — so you stay cool even on warmer nights without having to flip or adjust the pillow.

  • Easy-off cover

    Unzip the cover, toss it in the machine at 30°C, back on in minutes. A pillow that sits between your legs every night needs to actually stay clean — this one makes it effortless.

Not just for side sleepers.

Pregnant and struggling to find a comfortable position after 20 weeks? The SideRest Pillow takes the weight off your hips and bump simultaneously. Just want to stop waking up stiff every morning? It works for that too. One pillow, every stage — from the first trimester to every night after.

Wake up feeling like yourself again

Side sleepers know the feeling — legs tangled, hips uncomfortable, alarm going off before you feel remotely ready. The SideRest Pillow sits quietly between your knees all night, holding everything in place so you stop waking up to readjust and actually get through to morning.

  • Pressure-free design

    Memory foam that cushions without squeezing — soft enough to forget it's there, firm enough to actually work. No compression, no restricted circulation. Just support that lasts all night.

  • Adjustable strap

    Elastic strap wraps around your leg and keeps the pillow with you whether you sleep still or shift sides ten times a night. Set it once before bed — forget about it until morning.

  • Compact dimensions

    25 × 23 × 13cm — compact enough to fit in a weekend bag, supportive enough for every night at home. Takes up less space than a standard pillow but does significantly more.

FAQ

Most customers notice a difference from the very first use — less tossing, a more settled position. Give it 3–5 nights to fully adjust, especially if you're not used to sleeping with leg support.

The adjustable elastic strap wraps around your leg and keeps the pillow in position — even if you shift or roll over during the night. No more waking up to find it on the floor.

Primarily designed for side sleepers, but it also works under your thighs for back sleepers, or beneath your calves for elevated leg support. One pillow, genuinely multiple uses.

Simply unzip the cover and machine wash on a gentle cycle (30°C). The memory foam core — spot clean only, then air dry. Takes about 60 seconds to put back together.

Unlike hollow fibre pillows, the memory foam core maintains its shape night after night. It's dense enough to provide consistent support — not the kind of thing you'll be replacing in six months.

Many of our customers use it throughout pregnancy — particularly in the second and third trimester when side sleeping becomes the most comfortable position. Lightweight and easy to adjust as your body changes.

Like most memory foam products, there may be a very mild scent when first unboxed. It airs out fully within a few hours — just leave it unwrapped for a bit before your first night.
