Подушка для коленей Selene™ для сна на боку

When you sleep on your side, the top leg drops forward and turns the spine out of line for the whole night. Selene sits between your knees and stops that: its hourglass contour keeps your legs stacked, your pelvis level and your spine straight, with no knee resting bone on bone against the other.

The firm 50D memory foam keeps its shape under your legs and does not squash flat, and an adjustable strap holds the pillow in place however much you move. The breathable charcoal bamboo-blend cover unzips for washing.

26 x 20 x 15 cm, 450 g. Made for side sleepers who want their knees apart and their hips level through the night.

Take off the cover using the zip on the back. Machine wash it cold on a gentle cycle with a mild detergent; the bamboo-blend fabric stays soft with gentle care. Dry it flat in the air or tumble dry low. Wash every 2-3 weeks. Never wash the memory foam core. If it gets wet, blot it and let it air dry completely in a well-ventilated place. Spot clean with a damp cloth when needed. The elastic strap can be washed separately by hand; let it air dry completely before putting it back. New foam can have a slight odour, so air it for 24 hours before first use

Core: High-density 50D memory foam gives firm cushioning that keeps its shape under the weight of the legs (typically 8-12kg). It is firmer than a standard pillow (25D-35D) because a knee pillow must not compress in the night: if it does, the knees touch and the spine goes out of line. The memory foam shapes slightly to the leg for comfort and keeps its structure. Listed as CertiPUR-US certified (no harmful chemicals).

Hourglass Contoured Shape: The hourglass shape, narrow in the centre and wider at top and bottom, is designed to sit between the knees without slipping. An indentation in the centre (8cm deep) holds the lower knee, and the upper surface supports the top knee. With contact on both sides the knees stay a set distance apart (12-15cm), which keeps the hips level without pushing the legs too far apart.

Spinal Alignment Mechanism: Without a knee pillow, gravity pulls the top leg forward when you lie on your side. That turns the pelvis, twists the lower spine and loads the lower back unevenly. The CalmEden Selene™ prevents it by keeping the knees apart and stacked one above the other, so the pelvis stays level, the spine stays straight from neck to tailbone and your weight is spread evenly over the mattress.

Hip Separation: The 15cm thickness sets the distance between the knees and, through them, between the hip joints. That takes pressure off the bony point of the outer hip, a common pressure point for side sleepers, and stops the weight of the top leg pressing on the lower one.

Adjustable Elastic Strap: The 50cm elastic strap (stretches to 80cm) goes round the upper thigh and closes with a hook-and-loop fastener. It stops the pillow shifting or falling out in the night, which matters most for restless sleepers who change position often. It adjusts to thighs from 40cm to 70cm round. The elastic is soft and breathable and does not dig into the skin.

Cover: Charcoal grey bamboo-blend fabric (60% bamboo viscose, 40% polyester) is breathable and durable. Bamboo viscose wicks moisture away from the skin, helps keep an even temperature and is described as hypoallergenic. The polyester adds strength and reduces creasing. Charcoal grey is practical, since it hides stains, and suits a modern bedroom. The cover comes off with a hidden zip on the back.
