Quick Answer
A knee pillow is a specialized ergonomic cushion designed to be placed between the legs for side sleepers or under the knees for back sleepers. It is best suited for individuals seeking to improve their sleeping posture and spinal alignment during rest. While highly effective for many, a key limitation is that it may feel restrictive for active sleepers who frequently toss and turn throughout the night.
What Are Knee Pillows?
Knee pillows are ergonomic support tools typically crafted from high-density memory foam or cooling gel-infused materials. Unlike standard bed pillows, they are shaped to fit the contours of the legs, often featuring an hourglass or semi-cylinder design.
