What is Purple Pillow?

Purple is a well-known sleep brand, popular for its unique Purple Pillow. Made with the company’s own proprietary hyper-elastic polymer grid, the pillow is designed to be firmer at the edges for added support and softer in the middle. The brand carries a range of pillows, from the original Purple Pillow to the Purple Harmony and the Purple Plush Pillow. Those wanting to customize the height of the pillow can use the two boosters that come with the pillow or purchase additional ones.

What to consider when choosing a pillow

1. Purple Pillow: Firmness and loft

When choosing a Purple Pillow, the firmness and loft qualities are important considerations to keep in mind. The firmness of the Purple Pillow is quite firm, providing great support and working well for larger-framed people. The Purple Harmony also features the company’s signature grid structure, but with more cushion, making it softer than the Purple Pillow. The Purple Plush Pillow is a more traditional pillow, filled with polyester fluff and providing a softer feel. By using the two boosters, customers can customize the height of the pillow and adjust its firmness. For back sleepers, the Purple Pillow is recommended, as it is firmer than the Harmony. For side sleepers, the Harmony is softer and more suitable. Stomach sleepers would prefer the Purple Plush Pillow, as it is quite soft and malleable. However, it’s important to note that this pillow does not feature the company’s smart comfort grid. Ultimately, the decision of which Purple pillow to choose depends greatly on body type, sleeping position, and preference.

2. Purple Pillow: Size and shape

When considering a Purple pillow, size and shape are important factors to keep in mind. The Purple Pillow is available in one size of 24” x 16” and has a 3-4.5” loft. Its shape is quite different from traditional pillows as it features a flat surface and steep edges, resembling more of a chicken nugget than a ravioli. The Purple Harmony Pillow has a slightly larger size of 26” x 17” and is available in 6.5” or 7.5” loft. It has a core of Talalay latex and a Purple Grid (Hyper-Elastic Polymer). The Purple Plush Pillow has a size of 24″ x 16″ and a 7″ loft, made with interlocking polyester fiber puff balls. The Kid Purple Pillow has a size of 18″ x 13″ and a 3.25″ loft with a Purple Grid (Hyper-Elastic Polymer).

Overall, the Purple Pillow is best for back sleepers, as it is thinner compared to the Harmony, and it is more expensive than other pillows for back sleepers.

3. Purple Pillow: Material and construction

When deciding on the right Purple Pillow for your bed, the materials used and the construction of the pillow should be taken into consideration. The cover of the Purple Pillow is a blend of 88 percent polyester, 9 percent spandex mesh, and 3 percent nylon, making it super stretchy and breathable. The core of the Purple Pillow is made up of the Purple grid, a hyper-elastic polymer that has a non-toxic polyethylene copolymer powder coating. This helps to prevent the grid from sticking to itself. To add extra loft and support, adjustable pillow boosters are made of polyurethane foam and covered in 100 percent polyester fabric.

Comparing the Purple Pillow to other pillows on the market, the Purple Pillow offers a plusher feel without sacrificing support. It contains 3″ of Purple’s hyper-elastic polymer grid, making it quite firm and providing great support, especially for larger-framed people. Therefore, when choosing a Purple Pillow, it is important to consider the materials and construction of the pillow to ensure that it meets your needs.

4. Purple Pillow: Comfort and support

The Purple Pillow is designed to offer contouring support and comfort for those in need of pressure relief. It has a low profile and firm feel which may not be suitable for stomach or side sleepers. However, back sleepers tend to find it more comfortable. The Purple Pillow is also known for its cooling effects and breathable cover, making it ideal for hot sleepers. Additionally, it is durable and comes with a warranty and a sleep trial period.

5. Purple Pillow: Breathability and ventilation

When it comes to choosing the best pillow for breathability and ventilation, there are a few factors to consider. First, the type of material used in the pillow will impact its breathability. Pillows with breathable fabrics and mesh covers, like the Purple Pillow, help promote air circulation throughout the night. Additionally, the Purple Grid technology used in the Purple Pillow creates open-air channels that allow for lots of airflow. The material should also be moisture-wicking, which helps prevent sweat from accumulating on the pillow.

Another factor to consider is the pillow’s firmness and adjustability. The Purple Pillow is adjustable with two removable polyfoam boosters, allowing you to find the ideal height and feel to suit your needs. The Purple Grid conforms to the contours of your neck and head to provide a better fit for your body. Firmness also helps prevent the pillow from becoming flat or lumpy.

Finally, it’s important to consider how well the pillow resists heat. The Purple Pillow helps to promote air circulation throughout the night and reduce heat retention. The breathable mesh cover and the Purple Grid’s open-air channels allow for maximum airflow, ensuring that body heat does not become trapped in the pillow.

All in all, the Purple Pillow is an excellent choice for hot sleepers and those looking for breathability and ventilation.

6. Purple Pillow: Softness and fluffiness

The Purple Pillow offers an innovative design that is unlike other traditional pillows. It is made from a hyper-elastic polymer material and contains a 3-inch grid layer and two boosters that can be removed or added to adjust the height of the pillow. The ultra-fine gel fibers and hypoallergenic properties of the pillow make it a great choice for those who need extra support and breathability. Its silicone-coated, down-alternative fibers help to reduce clumping and allergens. As for its softness and fluffiness, the Purple Pillow has a medium-firm feel and can mimic the feel of a feather or down-filled pillow. It is firm enough to offer support, but it is also flexible enough so that it can be adjusted to suit individual comfort preferences.

7. Purple Pillow: Adjustability

The Purple Pillow is adjustable, allowing users to customize the height and feel of the pillow to suit their individual needs. The two removable polyfoam boosters make the Purple Pillow adjustable, so it’s easier to find the ideal height and feel to suit your needs. The Purple Grid conforms to the contours of your neck and head to provide a better fit for your body. Additionally, the Purple Grid is designed to retain its shape, ensuring the pillow remains at its desired height and level of firmness.

8. Purple Pillow: Cost and budget

When it comes to choosing a Purple pillow, the cost and budget considerations are quite varied. The Purple pillow falls within a broad price range, with most models costing between $20 and $200. The flagship Purple Pillow costs less than the luxe Purple Harmony Pillow, while the Purple Plush Pillow is the most affordable option. The Kid Purple Pillow uses the same Purple Grid material but is smaller and lower-priced. The price for the Purple Pillow includes two removable boosters, with additional ones available for an extra cost. Finally, the Purple Complete Comfort Sheet Set, Purple Duvet, Purple Harmony Pillow, and Purple Mattress Protector can be purchased separately. It’s worth noting that discounts and offers are available through the manufacturer, so be sure to take advantage of those if you’re on a budget.

9. Purple Pillow: Supportive design

The Purple Pillow is designed with contouring hyper-elastic polymer, providing pressure relief and comfort for those who need it. Its unique shape and loft level make it highly supportive for back sleepers, while side sleepers may need to add extra boosters for neck support. The Purple Pillow is firmer around the edges for extra support and softer in the middle, but some customers have complained that it’s not ideal for side sleeping or stomach sleeping due to its low profile. However, back sleepers generally have better things to say about it and find it more comfortable. Thanks to its ergonomic neck support and cooling properties, the Purple Pillow is a great option for those with neck pain, larger-framed people, and hot sleepers.

10. Purple Pillow: Customizability

How customizable is the Purple Pillow? The Purple Pillow is made of a proprietary hyper-elastic polymer material that adjusts to the head and neck during sleep, with firmer edges for extra support and softer in the middle. It does not have the same customizable features as other pillows, such as being able to remove stuffing to find an ideal lift, but the Purple Plush pillow does have a zipper that can be used to make it slightly firmer or softer.

11. Purple Pillow: Temperature control

What features make the Purple Pillow temperature control feature unique?

The Purple Pillow features a breathable mesh cover and a gel grid to help regulate temperature. The breathable mesh cover allows for airflow, so it won’t trap body heat. The gel grid provides plenty of room for airflow, which helps keep the pillow cool and comfortable. Additionally, the pillow cover is moisture-wicking, so any sweat will quickly be absorbed and dissipate. Additionally, the hyper-elastic polymers used in the pillow’s construction help keep it responsive, bouncy, and comfortable while still providing the pressure relief and support needed. All of these features combine to make the Purple pillow a great choice for hot sleepers.

12. Purple Pillow: Warranty

The Purple Pillow offers a 1-year limited warranty. If the pillow is found to be defective, Purple will repair or replace it, but the customer may be responsible for shipping costs. Additionally, Purple offers a 100-night sleep trial period so customers can test out the pillow at home and if it’s not the best fit, they can return it for a full refund.

13. Purple Pillow: Odor potential

The Purple Pillow is designed with a polymer matrix grid and ultra-fine gel fibers which make it highly responsive while still being comfortable. The hypoallergenic fibers allow airflow, creating a breathable pillow with no risk of allergens or dust mites. Customers have also noted that when opened, the Purple Pillow does not have a strong odor, unlike bed-in-a-box mattresses that have a slight chemical smell due to off-gassing from memory foam. Furthermore, the Purple Cloud Pillow has won the Intertek CleanAir GOLD certification, meaning it meets standards for reduced volatile organic compounds (VOCs).

14. Purple Pillow: Weight and bulk

When it comes to choosing a Purple Pillow, weight and bulk considerations should be taken into account. The Purple Pillow weighs 10lbs, which is heavier than many other pillows, but still provides excellent pressure relief due to its contouring hyper-elastic polymer. Back sleepers should find that the 3″ layer of polymer grid is enough to provide the right amount of comfort and support without needing to add a booster. Side sleepers should also be able to maintain a neutral alignment on the Purple Pillow, as it won’t compress or sag overnight.

Stomach sleepers, however, won’t find the Purple Pillow suitable for their sleeping position, as it is too tall. For larger people looking for significant neck support, the Purple Pillow should work well – though they may need the .5″ booster when back sleeping. Heavier side sleepers may need both boosters in order to keep their ears in line with their shoulders.

Overall, the Purple Pillow is a great option for those looking for firm and supportive material that can retain its shape long term.

15. Purple Pillow: Sleep positions

The Purple Pillow is designed to work with all three sleeping positions — back, stomach, and side. It is firm, but still contours to the head and neck, so it is a great choice for combination sleepers who switch between multiple positions. Additionally, the Purple Pillow provides cool sleeping temperatures due to its breathable cover and the air-flow design of the Purple Grid. For back sleepers, the shape and loft level of the Purple Pillow offer the most comfort and support. However, stomach sleepers may find the feel of the grid against their face too much. Side sleepers will need to add extra boosters in order to achieve enough height for neck support. As such, the Purple Pillow is best for combination sleepers, hot sleepers, those with neck pain, and back sleepers. In contrast, it may not be the best option for stomach sleepers, those who don’t want to regularly fluff their pillow, and those on a tight budget. Furthermore, side sleepers with smaller frames may want to look for a pillow with more loft for better support.

16. Purple Pillow: Size options

What size options are available for the Purple Pillow? The Purple Pillow is available in one size option, 24″ x 16″ x 3″, while the Purple Harmony Pillow is available in two size options of 26″ x 17″ and 24″ x 16″. The Purple Plush Pillow is available in 24″ x 16″ size option and the Kid Purple Pillow is available in 18″ x 13″ size option.

17. Purple Pillow: Grid design

The Purple Pillow is an attractive option for people seeking the distinct feel provided by the Purple Grid. This grid design is beneficial because it responds to the weight of your head and neck and quickly springs back to its normal shape when that weight is removed. The Purple Grid’s ability to adapt to pressure makes it a perfect option for all types of sleepers, as it can provide more support to those who need it. Additionally, the Purple Grid is breathable and ventilated, which prevents heat retention and keeps the pillow cool. The Purple Grid also keeps its shape night after night, so it won’t flatten out like other pillows. All of these features make the Purple Pillow an ideal choice for anyone seeking a comfortable, supportive pillow.

18. Purple Pillow: Foam core

The foam core of the Purple Pillow is made of a hyper-elastic polymer Purple Grid. This polymer grid is designed to provide a unique combination of comfort, support, breathability, and temperature-neutrality. The Purple Grid is hypoallergenic and certified to be free from harmful chemicals. It also has a non-toxic polyethylene copolymer powder coating which prevents it from sticking to itself. The Purple Grid is extremely responsive and contours to the shape of the head and neck for added pressure relief. Additionally, adjustable pillow boosters can be added underneath the Purple Grid to increase the loft, providing further comfort and support.

19. Purple Pillow: Construction

The Purple Pillow is a great choice for construction because of its contouring hyper-elastic polymer material. This material is highly responsive, providing adequate support for the head and neck while still being comfortable. It also has firmer edges for extra support, which helps prevent the pillow from collapsing under the weight of the head and neck. Furthermore, it is breathable and resistant to odors, and it is fairly lightweight at 10lbs. All of these features make the Purple Pillow an excellent choice for construction.

20. Purple Pillow: Reviewers’ ratings

According to the reference information given, reviewers have given the Purple Pillow an overall score of 4.3, with high ratings in Support, Cooling, Durability, Warranty, and Sleep Trial Period. Mattress Advisor gave it a total score of 8.9 out of 10, while Sleepopolis scored it 3.80 out of 5. Finally, Mattress Clarity also scored the Purple Pillow 3.80 out of 5.

The Purple Pillow is a unique pillow made with a proprietary polymer material that adjusts to the head and neck during sleeping.

The grid is made of a proprietary Purple material that is coated with a non-toxic polyethylene copolymer powder to prevent it from sticking to itself. The grid layer is 3 inches thick and is firmer around the edges for more support and softer in the middle for comfort. The boosters are made of thin slices of polyurethane foam and are 1 inch thick and 0.5 inch thick. The cover is a blend of 88 percent polyester, 9 percent spandex mesh, and 3 percent nylon, allowing for breathability and stretch. The cover is removable and machine washable. The Purple Pillow is recommended for back sleepers, as it is thinner than the Purple Harmony Pillow.

What is the difference between the Purple Pillow and other pillows?

The Purple Pillow is unlike any other pillow on the market, with a unique design featuring a 3-inch layer of their proprietary squishy gel grid that creates a firm and supportive surface for your head and neck. The edges aren’t tapered or rounded but have more of a blunt drop-off, making it look more similar in shape to a chicken nugget than other pillows. It also includes two “boosters” – thin slices of polyurethane foam – so you can customize its height.

Compared to other pillows, the Purple pillow is more expensive, but customers have had mixed experiences in terms of how well it supports different sleeping positions. It is designed to be more supportive for back sleepers, while stomach and side sleepers may find it too thin or bulky. It is also recommended to use a pillow case with the Purple Pillow to ensure it stays clean and in good condition.

What types of pillows does the Purple Pillow offer?

The Purple Pillow offers a variety of pillow options, including the Purple Pillow, the Purple Harmony Pillow, the Purple Plush Pillow, the Purple TwinCloud™, the Purple Cloud™ Pillow, and the Kid’s Purple Pillow. The Purple Pillow is made of Purple’s proprietary polymer material and is designed to be firmer around the edges for extra support and softer in the middle. The Purple Harmony Pillow is a little more cushiony compared to the Purple Pillow and is designed for those who like a firmer feel from their pillow. The Purple Plush Pillow is filled with polyester fluff and looks more like traditional pillows. The Purple TwinCloud™ and the Purple Cloud™ Pillow use the brand’s signature grid structure, which provides great airflow and breathability. Lastly, the Kid’s Purple Pillow is specifically designed for children. All of these pillows are suitable for all three sleeping positions — back, stomach, and side — and are great choices for combination sleepers.

What is the Purple Pillow’s loft level?

The Purple Pillow has a loft level of three inches, which is on the lower side. However, it comes with two adjustable pillow boosters, one 1-inch tall and one ½-inch tall, that you can add to raise the loft up to four and a half inches or purchase additional boosters from Purple for a higher loft.

Does the Purple Pillow have adjustable firmness?

Customers have found that the Purple pillow is too thin and bulky for those who require more support and the firmness cannot be adjusted.

What is the best pillow for side, back, and stomach sleepers?

When it comes to finding the best pillow for side, back, and stomach sleepers, the Purple Cloud Pillow is a great option. It is designed to support all sleeping positions and can be molded for various needs and heights; it also keeps the head, neck, and spine aligned. Side sleepers will benefit from its adjustable loft, which helps keep the head and neck in proper alignment, while back sleepers should appreciate the low-to-medium loft level, which keeps the neck from becoming hyperextended. Stomach sleepers should look for a pillow that is not too tall and won’t put excessive pressure on the neck. The Purple Pillow is adjustable and can be supplemented with additional polyfoam boosters to achieve the ideal loft height. For lightweight stomach sleepers, the Casper Down Pillow is a great option since it is easily compressible. Ultimately, it’s important to find the pillow that is best suited for your body weight, sleeping position, and desired feel.
