Quick Answer
A leg pillow for side sleeper is an ergonomic cushion designed to be placed between the knees or thighs to maintain pelvic alignment. It suits individuals who sleep on their sides and experience discomfort from knee-on-knee pressure or lower back strain. However, the key limitation is that they can be restrictive for active sleepers who toss and turn, often slipping out of place during the night.

FAQ Section
Are ergonomic pillows worth it?
Whether an ergonomic pillow is worth the investment depends on your specific discomforts. For many, the improved alignment leads to a more restful night, but they are not a universal solution and require a period of habituation.

How long does it take to adjust to a new pillow?
Most users require approximately one week to acclimate to a leg pillow. During the first few nights, it is common to wake up and find the pillow has been kicked to the foot of the bed.
