Much of the credit for a good night’s sleep goes to your mattress, but your choice of pillow plays a big role, too. A great pillow offers enough support to comfortably cradle your neck while you snooze.

Just like mattresses, pillows can run the gamut of firmness options. What’s best for you depends on your personal sleeping position, body weight, and idea of comfort.

A firm pillow is usually most suitable if you spend much of the night on your side, because it keeps your neck and spine properly aligned.

Here’s what else to know about firm pillows, including our picks for the eight best.

In choosing the best firm pillows, we looked for those with high density and loft (or thickness) as an indication of firmness.

We also checked for features like:

  • adjustability
  • ease of cleaning
  • material quality

Finally, we reviewed customer feedback to make sure each pillow comes with rave reviews.

Best budget-friendly down firm pillow

Brooklinen Down Pillow

  • Price: $

Brooklinen offers a more budget-friendly down pillow that’s just as well reviewed as Parachute’s. More than 1,000 reviews describe this pillow as comfortable, supportive, and an excellent value.

Available in three densities based on the ratio of feathers to down clusters, this firm pillow is designed for full support of your back, neck, and head.

The company cautions that dry cleaning will shorten the lifespan of your pillow by removing the down’s natural oils, which causes clusters to break down faster. Instead, they recommend spot cleaning as needed.

Brooklinen also offers a 365-day return and exchange window.

There’s no universal standard for measuring pillow firmness. Generally, it’s a reference to how much “give” a pillow has when you put your head on it. Individual manufacturers often have their own scales as a reference point, so that’s a good place to begin.

If you’re unsure whether you’ll like a firm pillow, consider how you spend most of the night. Stomach sleepers should avoid firm pillows, which tend to have high loft.

Back and side sleepers can do well with medium-firm to firm pillows for proper alignment in the back and neck.

If you’re a combination sleeper, an adjustable pillow, or one that’s very responsive, will be a good option.

Pillow material also plays a role in firmness level. The firmest pillows are typically made with memory foam, latex, or buckwheat. You can also find firm options made with down or down alternative.

However, even the firmest down pillow may not be quite as firm as other types of pillows. A 2011 study of side-sleepers found that the cervico-thoracic spinal slope, or the tilt of the neck and upper back, varied the most when changing from a foam, latex, or polyester pillow to a feather pillow.

We spend a lot of time researching mattress options and what will work best for our body type, sleeping habits, and preferred sleeping positions. Applying that same logic to choosing a pillow is just as important.

A firm pillow can be a great choice for side sleepers. The greater density helps your spine and neck maintain a neutral position — the best way to ensure you don’t wake up with aches and pains.
