Choosing the Best Adjustable Pillow: Customized Support for Restful Sleep

What is an Adjustable Pillow?

An adjustable pillow works by allowing you to modify the amount of fill inside the pillow to achieve your desired level of support and comfort. This adaptability is particularly beneficial for individuals with specific comfort preferences or those who switch between different sleep positions.

Why an Adjustable Pillow?

One of the most important factors in having a comfortable, restful sleep is the alignment of your head, neck and spine. Remarkably, your pillow is responsible for 30% of your overall spinal alignment. With age, injury or painful conditions like arthritis, neck and spine alignment becomes increasingly important. 

 

 

To complicate matters, very few people stay in one position all night long. In fact, a study by the American Sleep Disorders Association and Sleep Research Society found that most of us change positions between 10 and 40 times per night. This means that in order to keep you comfortable, an adjustable pillow must be rejigged — frequently. If that isn't super easy to do, you either won’t adjust it at all (and possibly end up in pain), or will wake right up to make the adjustments, which will mess with your delicate circadian rhythm. 

How Does an Adjustable Pillow Work?

 


 

There are many different types of adjustable pillows, but they all are designed so you can modify the amount of internal fill within the pillow to achieve your perfect fit. The process typically involves the following steps:

  1. Unzip or open the adjustable pillow’s access point: Most adjustable pillows have a zipper or other opening that allows you to access the fill inside. 
  2. Add or remove fill: Depending on your preferences, you can add more fill to increase the loft and firmness or remove fill to create a softer, flatter pillow.
  3. Adjust the fill distribution: Once you have the desired amount of fill in your adjustable pillow, you can manipulate its distribution within the pillow’s cover to ensure even support and comfort. 
  4. Close the adjustable pillow’s access point: After making your adjustments, secure the zipper or opening to keep the fill in place. 

By following these steps, you can customize your adjustable pillow to suit your specific needs, whether you prefer a firmer, more supportive pillow or a softer, more malleable one.

What Kinds of Adjustable Pillows Are There?

There are various types of adjustable pillows available on the market, each with its own unique features and benefits. Some common types include:

Water Pillows: 

  • Adjustment is achieved by adding or removing water through a chamber. The water level directly affects the pillow's firmness - higher water levels result in a firmer pillow.
  • Adjusting the water level in a water pillow takes time, which can disrupt sleep patterns, and these pillows tend to be heavy.

Air-Adjusted Pillows:

  • These provide precise adjustment using an internal or external pump. Some models feature separate chambers for head and neck support, allowing for even more customized comfort.
  • Like water pillows, adjusting air pillows with a pump can be time consuming and complex, and air pillows often require a foam pad for additional comfort.

Shredded Memory Foam Pillows:

  • Shredded memory foam pillows, like the Parallel Pillow, allow you to add or remove filling by unzipping both the outer cover and the inner lining so you can achieve your perfect level of loft and support.
  • This system is fast and easy, plus it allows for more shaping of the internal fill as you sleep through the night. The Parallel Pillow arrives generously stuffed, and if you ever happen to need extra fill, we'll ship an extra bundle for free.

So, What Is the Best Adjustable Pillow for Me?

When you’re searching for the best adjustable pillow, we know the Parallel Pillow will stand out for its innovative design, eco-friendly materials, and commitment to providing a personalized sleep experience. Here are more reasons why the Parallel Pillow is an excellent choice in an adjustable pillow:

  1. Convenient Adjustability: The Parallel Adjustable Pillow features a quality side zipper that allows for easy removal or addition of fill, enabling you to fine-tune the loft and support whenever necessary. And, once you find your perfect fit, Parallel's unique blended fill can easily be sculpted to provide the ideal level of support, promoting proper spinal alignment and reducing pressure points. 
  2. Two Height Profiles: Instead of stuffing the heck out of a thin pillow or removing most of the fill from a thick one, the Parallel Pillow comes in High Profile and Low Profile versions. If you spend most of the night (or all of it) on your side, the High Profile Adjustable Pillow is right for you. If you spend most of the night on your stomach or back, go with the Low Profile Adjustable Pillow.
  3. Blutech Fusion Fill (BFF): The pillow’s proprietary adjustable fill blend consists of downy, hypoallergenic fibers and precision-cut gel visco foam, offering twice the airflow of conventional foam fills. This ensures a cool and breathable sleep environment throughout the night.
  4. Eco-Friendly Materials: The Parallel Pillow’s outer cover is made from TENCEL™, a sustainable and exceptionally soft material derived from renewable wood sources. The downy component in each Parallel Pillow's adjustable fill is made from the upcycled material of up to 23 plastic bottles. And we use plant-based ingredients in our precision-cut visco memory foam.

Investing in the right adjustable pillow is about prioritizing your sleep comfort while making a responsible choice for the environment. With its infinitely adjustable pillow design, high-quality materials, and focus on sustainability, the Parallel Pillow is an excellent option for anyone seeking a personalized and eco-friendly sleep experience and the best adjustable pillow, regardless of their sleep position.

We’re often surprised at the lengths to which people will go to find their perfect pillow. Some have closets filled with various pillow types they’ve tried, only to resume their quest after a few disappointing nights with the latest one.

And we’re delighted every time we hear that another buyer’s search has ended after discovering the Parallel Pillow. Sometimes that’s because they are finally sleeping at the right temperature, without pillow-flipping. Most often it is because they are finally getting exactly the support they need, even when they change positions.

The Parallel Pillow works for them because it’s different from all the others. It's not just adjustable, but infinitely adjustable. And our uniquely breathable, sculptable fill is easily tailored in loft, shape and level of support. We could say it’s the most adjustable of all adjustable pillows — but what exactly does that mean?

People’s Needs In a Pillow Vary. A Lot.


Those are real reviews. From real people like you.
The differences can be mind-blowing, especially for a pillow manufacturer! 
Making a fixed-thickness pillow that is right for everyone isn’t just hard to do.
It’s plain impossible.

One person’s “insanely overstuffed” is someone else’s “ridiculously thin.”
Our solution is to fill the Parallel Pillow generously — and to ship extra fluff for free to any customer who needs it. (We’ve got the numbers, and most do not.)

And while this can be a little hands-on, we have come to know it is the very best way too achieve absolutely perfect support, uniquely for you!
