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.
Why choose this pillow
5 Reasons Side Sleepers Wake Up Feeling Different
Knees stop grinding all night
The ergonomic shape sits between your knees and keeps them separated — so your hips stay aligned and you stop waking up stiff and tangled every morning.
Stays in place when you switch sides
Contoured design hugs your legs and moves with you — no repositioning at 3am because it slipped out from between your knees again.
Waking up stiff is a position problem
Most people blame the mattress. The real issue is knees stacked without support all night — one small change in position makes a measurable difference by morning.
Removable washable cover
Zip it off and throw it in the wash. Something between your legs every night should be easy to keep clean.

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.
