The Best Adjustable Pillow

Finding the right pillow can feel like a never‑ending quest. One night it is too flat, the next too thick.

An adjustable pillow solves that by letting you add or remove fill until the loft and firmness match exactly how you sleep.

Whether you are a back, side, or stomach sleeper, the ability to customize support can make a real difference in your sleep quality.

In this guide, we have researched the best adjustable pillow options on the market, evaluating each against consistent criteria, specifications, expert review consensus, and verified buyer feedback, to help you find the perfect fit for your needs.

Below are our top picks.

Best Adjustable Pillow Buying Guide

Fill Material and Composition

Most adjustable pillows use shredded memory foam, which provides a balance of contouring and support. Higher‑density foam tends to hold its shape longer, while cross‑cut or “crescent” foam pieces offer a softer, more pliable feel.

Some pillows combine shredded foam with microfiber or polyester fill for a plusher touch. When comparing materials, look for CertiPUR‑US certification to ensure the foam is free of harmful chemicals.

GREENGUARD Gold certification adds an extra layer of assurance for low emissions.

Adjustability and Ease of Use

The whole point of an adjustable pillow is the ability to change its loft and firmness. Most models feature a zippered cover that allows you to remove or add fill.

Some brands provide a separate bag of extra fill, so you can start with a little and add more if needed.

Pay attention to the size of the zipper opening and the texture of the foam, pulling out fill from a dense pillow can be messy. Pillows with a dual‑chamber design or separate inserts make customization even easier.

Loft and Sleep Position Compatibility

Your sleep position dictates the ideal pillow height (loft). Side sleepers generally need a higher loft (4, 6 inches) to fill the gap between the ear and shoulder.

Back sleepers usually prefer a medium loft (3, 5 inches) to support the natural curve of the neck. Stomach sleepers need a low loft (2, 3 inches) to avoid straining the neck.

An adjustable pillow lets you experiment with different amounts of fill to find your sweet spot. Many brands offer sizing guides based on your sleeping position and body type.

Cooling and Breathability

If you sleep hot, consider a pillow with cooling features. Some adjustable pillows incorporate gel‑infused memory foam, which draws heat away from the head. Others use ventilated foam or breathable cover fabrics like bamboo rayon, cotton, or Tencel.

A few models come with a separate cooling cover that can be removed and washed. While no pillow can keep you completely cool all night, these features help reduce heat retention compared to traditional memory foam.

Certifications and Safety

When choosing an adjustable pillow, look for independent certifications that verify material safety. CertiPUR‑US ensures the foam meets standards for content, emissions, and durability.

GREENGUARD Gold certification indicates the product has low chemical emissions, making it safer for indoor air quality. Some pillows also use OEKO‑TEX certified covers. These labels are especially important if you have allergies, asthma, or chemical sensitivities.

Frequently Asked Questions

How much fill should I remove from an adjustable pillow?

Start by sleeping on the pillow with the fill as‑is for a few nights.

If you wake up with neck pain or feel your head is tilted too far up or down, remove a handful of fill at a time.

Many brands include a storage bag for the extra fill, so you can easily add it back later if needed.

Are adjustable pillows good for side sleepers?

Yes, adjustable pillows are ideal for side sleepers because you can add fill to achieve the higher loft needed to keep your spine aligned.

Look for models that come with extra fill or have a high starting loft, like the Coop Home Goods Original (King) or the Sidney Sleep curved pillow.

How do I clean an adjustable pillow?

Most adjustable pillows have a removable, machine‑washable outer cover. The foam fill should not be washed, spot clean it with mild soap and water if needed, then air dry completely before returning to the cover. Check the care instructions for your specific pillow.

Do adjustable pillows go flat over time?

Shredded memory foam can lose some loft after months of use, but you can often restore it by fluffing the pillow or adding back fill that you saved.

High‑quality foams with higher density (like those from Coop Home Goods) tend to hold their shape longer.

What is the difference between shredded memory foam and solid memory foam?

Solid memory foam provides a uniform, contouring feel but cannot be adjusted. Shredded memory foam is cut into small pieces, allowing air to flow more freely and enabling you to change the loft by adding or removing fill.

This makes shredded foam more breathable and customizable.

Can I use an adjustable pillow with a cervical pillow shape?

Yes, some adjustable pillows have a contoured or curved shape designed to support the neck curve (like the Sidney Sleep Adjustable Curved Pillow). You can still adjust the fill inside, but the overall shape is fixed.

These are especially helpful for side and back sleepers with neck pain.
