King size pillows are generously sized to give individuals ample room to sleep comfortably across a wider portion of the bed than a standard-size pillow allows. However, while king size pillows all have about the same measurements (usually 20 by 36 inches), they offer a variety of firmness options, fill materials, cooling properties, and support levels for different sleeping positions.

What to Consider When Choosing the Best King Size Pillows
As mentioned above, there are quite a few features to consider when choosing the best king size pillows. Continue reading to learn more about what to look for as you shop, including the fill material, cover material, loft and density, firmness rating, and temperature-regulating capabilities. You’ll also want to consider your preferred sleeping position and if the pillow will offer the necessary neck support and spinal alignment based on that position.
The material used to fill a pillow will have a significant impact on the overall feel and the support it provides. There are numerous fill types from which to choose:
- Down: Down pillows use the inner feathers from geese or ducks as filling. These feathers are very soft and lightweight. This means down pillows are not as firm as most other options, so they are a better choice for individuals looking for a softer pillow. Down is not recommended for individuals with allergies.
- Memory foam: Memory foam pillows are very supportive and can help keep the spine in alignment during sleep since they conform to the shape of the head, neck, and shoulders. However, memory foam can trap heat, causing individuals to become too warm when they sleep.
- Shredded memory foam: Shredded memory foam is an alternative to a standard memory foam pillow. These pillows feature tiny pieces—or shreds—of foam that offer the conforming properties of memory foam while allowing more air to circulate for a cooler night’s sleep. Many shredded memory foam pillows also allow individuals to add or remove foam to customize the loft and amount of support the pillow offers.
- Latex: Latex is contouring, like memory foam, but it doesn’t retain heat the same way. Latex is also more responsive than a standard memory foam pillow, so it may be a better choice for individuals who move around as they sleep.
- Synthetic: Synthetic filling offers a hypoallergenic alternative to down pillows. These pillows are typically made from polyester and are often firmer than some other pillow types.
- Cotton or wool: Pillows with cotton or wool filling will likely be rather firm since they don’t compress like the above-mentioned materials. Since these pillows typically feature organic cotton or natural wool, they may be a good option for individuals who suffer from allergies, as these materials aren’t susceptible to mold or dust mites.
In addition to considering the material for the filling, think about the material used to create the cover. Cotton and bamboo are two of the most common materials for pillow covers. Cotton is a very breathable material that can absorb sweat to keep your body cooler during the night. It is also soft and comfortable.
Bamboo pillows feature a unique cover referred to as casing. This cover is made by processing bamboo pulp into a woven material. The material still retains some of the viscous properties of the bamboo pulp, creating a plush cover.
Since bamboo is a natural fiber, it is less likely to cause an allergic reaction than some other materials. Bamboo is also antimicrobial; it can help keep bacteria from forming on a pillow’s surface to promote healthier sleep.
Loft and Density
Loft indicates the thickness of a pillow. It greatly impacts the amount of support a pillow offers and plays a big role in determining if a specific pillow will be a good fit for an individual’s preferred sleep position. Pillows typically fall into one of three categories related to loft: low loft (less than 3 inches thick), medium loft (3 to 5 inches thick), and high loft (more than 5 inches thick).
Density is closely related to firmness. High-density pillows will prevent an individual’s head from sinking too deep into the pillow, whereas pillows with a lower density will have more give and allow the head to sink in more. Individuals who need a more supportive pillow to relieve neck pain or shoulder tension should look for a denser pillow, as it will help keep the spine aligned.
The firmness of a pillow can range from very firm to very soft. Some pillow manufacturers will measure firmness using a five-point scale of firm, medium-firm, medium, medium-soft, and soft.
- Firm: Firm pillows provide the least amount of give and the most support for the neck, back, and shoulders of side-sleepers. Most back- and stomach-sleepers will find that a firm pillow does not offer enough contouring for comfortable sleep.
- Medium-firm: Medium-firm pillows are still firm, but they offer more cushioning than purely firm pillows. They can be a good choice for back-sleepers and some side-sleepers who need the support of a firm pillow but still want some contouring to their head, neck, and shoulders.
- Medium: Medium pillows are popular among individuals who change sleep positions throughout the night. They can offer adequate support for most sleepers.
- Medium-soft: Medium-soft pillows can be ideal for stomach-sleepers and some back-sleepers. They are not as supportive as firmer pillows and may be too soft for many back-sleepers, especially heavier individuals.
- Soft: Soft pillows are generally too soft for most side- and back-sleepers. However, many stomach-sleepers find that soft pillows are ideal for scrunching under their head while they sleep.
As we’ve alluded to in previous sections, your sleeping position can greatly impact which king size pillow will be best for you. The best pillows for side-sleepers are typically firm or extra firm. These pillows create more of an even surface to keep the neck and spine in alignment.
Back-sleepers generally sleep more comfortably with a medium or medium-firm pillow. These pillows offer sufficient support to keep the spine aligned, while also contouring to the sleeper’s head, neck, and shoulders for all-night comfort.
Stomach-sleepers require the softest pillows. A pillow that is too firm will elevate a stomach-sleeper’s head and neck too much and misalign the spine during sleep. Softer pillows, on the other hand, allow the head to sink into the pillow at an angle that keeps the spine aligned.
Some people don’t have a fixed sleeping position and may switch between two or three different positions overnight. In most cases, a medium pillow will be the most adaptive and comfortable option for these individuals.
Support and Spinal Alignment
Choosing a pillow that offers the proper amount of support will help to keep you comfortable overnight and reduce aches and pains in the morning. As mentioned above, different sleep positions require different amounts of support.
Side-sleepers require the greatest amount of support, followed by back-sleepers. Stomach-sleepers don’t require as much support. Memory foam and latex are materials that offer more support, while down pillows provide less support.
Keeping the neck and spine aligned during sleep is important, especially for individuals who suffer from back or neck pain. Selecting a pillow that offers the right firmness level for your sleep position can position the head at a comfortable angle to ensure the spine stays in alignment and reduce morning pain and stiffness.
Finally, consider the temperature-regulating capabilities of the pillow, especially if you tend to become warm when you sleep. Cooling pillows often feature gel, graphite, copper, or phase-change materials that pull heat away from an individual’s head to keep them cooler as they sleep.
Cooling pillows also typically include a moisture-wicking cover made from either bamboo, cotton, or wool. These materials wick away sweat from an individual and also dry quickly to prevent the pillowcase from becoming wet from that sweat. Temperature-regulating pillows also use more breathable materials that allow for maximum airflow for a comfortable sleep.
