Buying Guide for the Best Pillow For Side And Back Sleepers
Choosing the right pillow for side and back sleepers is essential for a good night’s sleep and may help prevent neck, shoulder, or back pain. Both sleeping positions need support that keeps the spine aligned; a pillow’s height, firmness, and materials all play important roles. Knowing what to look for means you’ll rest more comfortably and wake up refreshed.Loft (Height)Loft refers to how high or thick the pillow is when it’s lying flat. This spec is important because a pillow with the right loft supports the natural curve of your neck and keeps your head in line with your spine. Low-loft pillows are flatter, mid-loft pillows have moderate height, and high-loft pillows are quite thick. Side sleepers often need a higher loft to fill the gap between the neck and shoulder, while back sleepers usually do best with a medium loft that keeps the head from being pushed too far forward or backward. If you switch between these positions, a medium to slightly high loft can be a good balance, but pay attention to how your neck feels in the morning to help you decide.
FirmnessFirmness is about how soft or hard the pillow feels when you put your head on it. It matters because a pillow that's too soft may let your head sink too much, while one that's too firm may not let your head settle in comfortably. Pillows range from soft (which compress easily), medium (a good mix of support and comfort), to firm (which holds its shape and lifts your head more). Side sleepers usually benefit from a medium-firm pillow to adequately support the gap between head, neck, and shoulder. Back sleepers often prefer medium-firm for stability without pushing the head too far forward. If you change positions at night, medium-firm offers balance for most people.
Pillow Shape and SizeThe shape and size of the pillow can affect how well it supports your sleeping posture. Regular rectangular pillows fit most sleepers, but some pillows are contoured or designed with a dip in the middle for neck support, which can be helpful if you have neck stiffness or pain. Sizes generally include standard, queen, and king. If you move a lot in your sleep, a larger pillow can give you more space to adjust, while a contoured pillow might help you keep your head and neck in a more stable position, particularly if you’re working on better posture.
Fill MaterialThe fill material is what the pillow is made from inside, and different materials affect softness, support, breathability, and hypoallergenic properties. Common fillings include memory foam (which shapes to your head and gives steady support), latex (which is supportive and stays cool), down or feather (which is soft and squishy), and synthetic fibers (which can mimic down and are often more affordable). Memory foam is good for stable support, which appeals to both side and back sleepers. If you’re sensitive to allergies, synthetic fills or latex are often suitable. If you like adjusting your pillow's shape, down or shredded foam can work better for you.
AdjustabilitySome pillows let you remove or add filling to adjust their loft and firmness, which is helpful if you’re not sure what feels best or if your preferences change over time. This spec makes a pillow more versatile and personalizable, creating a better fit for your comfort needs. If you shift between side and back sleeping, or if your comfort needs change seasonally, an adjustable pillow can be a convenient solution.
Breathability and CoolingBreathability refers to how well the pillow allows air to move through it and how well it stays cool overnight. This feature is important if you tend to sleep warm or sweat during the night. Materials like latex, gel-infused foams, and certain synthetic fibers help keep the pillow cooler. If you often feel hot at night, look for a pillow described as cooling or breathable to keep you comfortable.
