What Are the Best Firm Pillows for Side Sleepers?

Firm Pillows for Side Sleepers

Side sleepers are best using firm, high loft pillows.

When on your side, your pillow’s job is to fill the space between your head and your mattress while keeping your body in a neutral sleeping position — your neck and back should be in a straight line without any upward or downward bends in your spine. Neutral alignment keeps all the bits and pieces in your back in in their ideal positions, preventing unnecessary pressure on your discs, muscles and nerves. Stay neutrally aligned and you’ll avoid discomfort (or worse).

Side sleepers get the best rest on thick, firm pillows.

Side sleepers will be most comfortable on a firm or extra-firm pillow. Softer pillow types like down tend to collapse under the weight of your head during the night. This loss of support will cause your head and neck to bend downwards, resulting in unnecessary strains that can lead to neck or back pain.

Additionally, side sleepers are advised to use a high loft (thick) pillow. This is simply because there is more space to fill between your head and the mattress when on your side than when on your back or stomach.

What are the best firm pillows for side sleepers?

No single pillow type works for all side sleepers. Fortunately we have lots of choices. Many different types can provide the comfort you need as long as they’re relatively firm and thick. Your side sleeper pillow should:

  1. provide enough loft (height) to keep your spine straight, but isn’t so thick that it bends your neck upwards out of alignment.
  2. provide consistent support throughout the night. The fill does not collapse on itself, allowing your neck to bend downward.
  3. be comfortable. Ultimately, it’s best to trust your instincts. If a particular pillow works well for you, stick with it.

Bonus Feature: Adjustability

Some pillows are adjustable and allow fill to be added or removed from a zippered case. Adjustable types are most often filled with buckwheat hulls or similar materials that are easily removed or added to a pillow’s case (this won’t work with most latex or down pillows). If you’ve decided on an adjustable pillow, you’ll be able to dial in the loft (thickness) exactly to your preference. With non-adjustable types you’ll need to be a little more discerning in your purchase to be sure you’ve got the proper loft to suit your preferences.

Sleep on it!

Squeezing a pillow inside plastic packaging at the store isn’t the way to find your ideal pillow. You really need to test drive them in your own bed. There is no substitute for literally sleeping on it.

Check the manufacturer’s return policy and make sure that you’re able to try it for at least a week. If it’s not right for you, toss it back in the box and return it. You spend a third of your life with your head resting on a pillow, so a little shopping and experimentation is absolutely worth it.

A side sleeper needs a firm pillow with enough loft to support their neck and head while keeping their body in a straight, neutral sleeping position. Above all, your side sleeper pillow should be comfortable – trust your instincts! Experiment with different pillow types and find what works for you.
