Contour Legacy Leg & Knee Foam Support Pillow review

Despite the “leg” in its name, the Legacy is a compact hourglass that sits between your thighs and knees. It doesn't run down to your ankles. Contour lists it at 10 inches tall, 9 inches wide and 6 inches deep, tapering to 2¾ inches at the edges (about 25 × 23 × 15 cm)^[1]. The law tag on the original model gives a finished size of 9.9 × 9.9 × 6 inches^[2]. The 6-inch depth is the number that matters most. It's how far apart the pillow holds your knees at its thickest point.

Three details set the shape apart from a plain foam block. Contour describes a center incline that follows the slope of your thighs to keep the pillow in place, a curved end that fits against your pelvis, and tapered edges so your knees can bend without catching on the sheets. It also says the Legacy is 20% longer than most traditional leg pillows^[1]. The law tag lists US patent 10,893,762^[2], which describes the same idea in more detail: a concave end that leaves room for the groin, and a rounded knee end that leaves your knees free to bend, so you can curl into a fetal position without pressure points^[3].

What the Legacy doesn't do is hold up your shins and feet. Below the knee, your top leg is on its own, so your top foot can still drift toward the mattress. Contour's answer is a second pillow: it sells a two-pack that it says keeps your hips and ankles aligned^[4]. In a clinical review of outer hip pain, Alison Grimaldi and Angela Fearon suggest pillows between both the knees and the shins^[5], so a second Legacy, or any firm pillow lower down, follows the same logic.

The Legacy is memory foam, so it molds around your knees and gets a little softer as it warms. The law tag lists the filling as 100% polyurethane foam, 14.8 ounces (about 420 g) of it^[2]. Contour sells it as ventilated memory foam that responds to body heat and weight^[1]. That's how this foam behaves in general: the Polyurethane Foam Association notes that many memory foams soften with heat and recover their shape slowly after you lift your weight off^[6].

Descriptions of its firmness don't agree. Contour's Amazon listing calls it soft^[7]. In a 2019 hands-on review, The Sleep Captain's reviewer found the core had a rubbery feel and called the foam the “perfect degree of firm to support both legs”^[8]. Our research-based firmness rating is 6 out of 10: firmer than the 5 STARS UNITED, softer than the ComfiLife.

Heavier legs will press the center down further than the 6-inch spec suggests. Soft memory foam without enough density or thickness can bottom out^[6], and Contour doesn't publish a foam density, so there's no number to judge that by.

The vent holes are the Legacy's main defense against heat, and nobody has measured how well they work. Contour says air holes in the foam promote airflow and move heat away from your body^[7]. The Sleep Captain's reviewer, who had been waking up hot with a full-length body pillow, found that the holes run side to side straight through the core. They judged the thin quilted cover as breathable as claimed, but left the cooling question to a longer test^[8]. We found no lab test of the pillow's temperature.

The original cover is a quilted blend of 62% polyester and 38% lyocell^[2]. If you run hot, Contour also sells a Legacy Cool version in the same 10 × 9 × 6 inch shape. It adds a gel layer that Contour says is cool to the touch, plus a cooling nylon cover^[9]. As with the vents, we found no independent test of how much cooler it sleeps. Our cooling guide covers fixes that work on any pillow, such as a cooler bedroom and breathable bedding.

For an average frame, probably. If you're tall or broad-hipped, check the fit before the return window closes. The aim is a top thigh that runs roughly level with the mattress, so your top hip isn't pulled down and inward^[5]. The Legacy holds your knees up to 6 inches (15 cm) apart at its thickest point, less toward its tapered edges^[1], and less again once the foam compresses under your legs.

The Sleep Captain's reviewer found it “quite a bit smaller than we anticipated, even for a knee pillow”^[8], which matches the size complaint in our summary above. If you're about 6 feet or taller, or your hips are wide for your height, the Cushion Lab Large is built for sleepers about 5′8″ and up. Our knee pillow guide explains a quick photo check that tells you whether any pillow is thick enough.

The Legacy relies on its shape, not a strap, to stay between your legs. Contour says its crescent shape contours to your legs so you can move freely, and it describes straps as circulation-restricting^[7]. The center incline is there to stop the pillow sliding out as your thighs slope toward your hips^[1].

That works best if you mostly stay on one side. When you roll over, you either carry the pillow with you or lose it. Bending your knees a little more helps your legs grip it, and Mayo Clinic's advice for back pain already suggests drawing your legs up slightly toward your chest with a pillow between them^[10]. If it still ends up on the floor most nights, a strapped pillow or a body pillow is harder to lose.

Wash the cover, never the foam. The law tag says the cover can go in the machine on a gentle cycle, with non-chlorine bleach if needed, then air dry or tumble dry on low. The foam core should not be washed, bleached, ironed or dry-cleaned, only air dried^[2]. Contour sells replacement zip covers in the same quilted polyester and lyocell blend^[11], so a worn cover doesn't mean a new pillow.

How long the foam keeps its shape is an open question. We found no long-term durability test, and Contour publishes no foam density, the spec the foam industry links to durability^[6]. Contour's Amazon listing promises a one-year warranty^[7]. Its own policy covers defects in materials and workmanship, not normal wear and tear. It gives a full year on orders from contourliving.com, but only 90 days on orders from authorized retailers unless you register the pillow within 30 days of purchase. The policy also says warranties don't extend to reseller sites such as Amazon unless Contour itself sold the pillow new^[12]. Register it wherever you buy, and keep proof of who sold it. The 45-day comfort guarantee applies only to orders placed directly with Contour, and you pay the return shipping^[1,13].

Buy it if you sleep mostly on your side and your hips, lower back or knees complain about it. Without support, your top leg pulls forward and twists your torso. A pillow between your legs stops that and keeps your hips and spine aligned^[14]. Our knee pillow guide covers the evidence, which rests on biomechanics and clinical advice rather than trials of knee pillows themselves.

• Outer hip pain (bursitis or gluteal tendinopathy): a good match. Pain at the point of the hip is typically worse at night when you lie on that side^[15], and the top hip is compressed too when the leg drops^[5]. Because the Legacy reaches up the thighs, it holds the whole upper leg level, not just the knee. Add a pillow at your shins if your foot sags.
• Sciatica: an NHS specialist hospital recommends a small, firm cushion between the knees^[16]. The Legacy is small but not especially firm. If it squashes flat under your legs, the ComfiLife is the firmer choice.
• Pregnancy: the NHS suggests a pillow between your legs for pelvic pain in pregnancy^[17], and Contour markets the Legacy for pregnancy^[1]. Later on you may also want belly and back support, which a U- or C-shaped body pillow adds.
• After hip replacement: follow your surgeon. Precautions usually apply for about the first six weeks and depend on the surgical approach^[18]. Hospital for Special Surgery tells posterior-approach patients to keep at least two firm pillows between their legs so they never cross^[19]. One memory foam Legacy doesn't meet that rule, and Contour itself says the pillow is not a medical device^[1].
• Bony or arthritic knees: keeping your knees from pressing together is the simplest benefit of any knee pillow. Pressure-care guides for people at risk of sores recommend pillows between the knees and ankles so bony points don't touch^[20]. After a knee replacement, though, Hospital for Special Surgery says not to put a pillow under the operated knee^[21], so ask your team before you use the Legacy in any position.
• Back sleepers: the Legacy is shaped to sit between your legs, and The Sleep Captain's reviewer doubted back sleepers would get much use from it^[8]. On your back, Cleveland Clinic suggests a small pillow under your knees instead^[14].
• Skip it if you need more than about 6 inches between your knees, if you flip sides many times a night and hate fishing a pillow out from under the covers, or if you want one pillow that supports your whole leg down to the ankle.

Point the curved end toward your pelvis, keep your knees near the thick middle, and bend them slightly.

1. Put the cover on first. In 2019, The Sleep Captain's reviewer found the core shipped in a plastic bag with the quilted cover packed separately, and noticed no strong odor on unboxing^[8].
2. Lie on your side and draw your knees up a little toward your chest^[10].
3. Slide the pillow between your thighs with the curved end up near your pelvis and the tapered edges toward your knees^[1]. Your knees should rest on the thick part, not on the thin outer edge.
4. If your top foot drops toward the mattress, put a second Legacy or a firm pillow between your shins^[5].
5. Give it a week or two. Judge it by how your hips and back feel at night and on waking, and send it back within the return window if it isn't helping.

The Legacy is our pick for thigh-and-knee coverage. The others win on firmness, softness or size.

• ComfiLife: a firmer, shorter hourglass at 9.8 × 7.9 × 6.3 inches^[22], with no vent holes listed. It costs less and suits the firm-cushion advice for sciatica. It doesn't reach as far up your thighs.
• 5 STARS UNITED: about the same footprint as the ComfiLife at 9.8 × 7.8 × 6 inches, and listed as soft^[23]. It's the one to try if your knees are bony or tender and firm foam feels like a brick between them.
• Cushion Lab Large: the choice if the Legacy's 6 inches leaves your top knee angled down.
• Body pillows such as the Coop body pillow or Snuggle-Pedic: better if you also want to rest your top arm, or if you need your whole leg supported. A knee pillow is smaller and takes up less of the bed.
