A 2017 cross-sectional Danish study revealed that 54.1% of the participants preferred sleeping on their side.
Sleeping on one side — on a pillow and mattress, which provides firm support — promotes even spine alignment, unlike lying on your stomach or back.
Side-sleeping also alleviates various sleep disorders, for instance, obstructive and central sleep apnea. If you’re a side-sleeper, Sleep Reviews‘ top picks for the 5 best side-sleeper pillows in 2021 will go a long way in helping you enjoy a peaceful night’s slumber.
Tips to Finding the Perfect Pillow for Side-Sleepers
A side-sleeper will typically need a thick, firm pillow to cushion the curvature between the head and neck to achieve the most suitable side-sleeping position.
Finding the perfect pillow for a side-sleeper can be quite tiresome. Don’t worry,; we’ll help you find the best model to accommodate your unique needs.
When purchasing a good side-sleeping pillow, consider the following attributes:
- Firmness — A pillow with mid-level firmness will provide the best support. One that’s too soft or firm will be uncomfortable and may lead to alignment issues.
- Loft — Medium to high thickness (loft) provides just the right amount of head and neck support that a side-sleeper needs. Consider buying an adjustable pillow that gives you the power to custom make your perfect loft level.
- Pressure relief — A good pillow will ease pressure points in the shoulders and hips, which (possibly) developed due to using the wrong pillow and mattress.
- Price — Pillows constructed from materials like memory foam, down, and latex are usually expensive, while more affordable options tend to use polyfoam or feathers.
- Quality materials — The materials used in a pillows’ filling and cover will impact its temperature regulation, shape retention, and longevity. A model constructed using high-quality materials and advanced technology will almost always outperform other pillows on the market.
- Shape — Every pillow loses its shape and needs to be fluffed out regularly. Materials such as latex and solid foam require less maintenance and fluffing.
- Support — Spine alignment is vital for a side-sleeper. Therefore, you’ll need a pillow that doesn’t raise or sink your neck but instead provides the perfect neck curvature support.
The side-pillows below are the best in their category, having performed brilliantly in several research tests and received rave reviews for their firmness, durability, and washability.
Always follow care instructions to prolong the lifespan of your pillows.
