Buying Guide

Choose the right shape for side sleeping

Knee-contour pillows keep knees separated and align hips and lower back; look for a shape that fits comfortably between your thighs without forcing your legs apart

Memory foam vs. standard foam

Memory foam molds to contours and can reduce pressure points for sciatica, while standard foam may offer firmer, quicker rebound—pick based on how much contouring you prefer

Consider thickness and loft

Thickness affects hip tilt and spinal alignment; medium lofts typically suit average builds, while taller or larger users may need thicker cushions for effective separation

Check cover material and washability

Breathable, removable covers simplify cleaning and improve comfort; look for machine-washable fabrics to maintain hygiene and longevity

Assess brand ratings and value

Use average customer rating and price to judge value—products with consistent ratings around 4.4 can indicate reliable performance relative to cost
