Purple PurpleFlex Mattress Overview


  • Excellent Cooling: The Purple PurpleFlex mattress has a great cooling effect as a result of the top layers of its structure. The SoftFlex cover and the GelFlex Grid, which contain gel material, draw heat away from the body and provide good temperature regulation.
  • Budget-Friendly: This mattress is manufactured with cost-effective materials that also aim to give you a great sleep experience. Its construction is simple, which puts the mattress at a lower price tag, making it available for purchase by most people.
  • Great Cushioning: This mattress provides excellent body cushioning as a result of the GelFlex Grid contouring to the body’s shape. It offers personalized support and adapts easily to your movements. This ensures the reduction of pressure points in areas like the hips and shoulders.


  • Available in Four Sizes Only: The available sizes of the Purple PurpleFlex mattress are limited to only four options, which does not cater to the various and diverse needs of all sleepers. This puts it at a disadvantage, as a lot of mattresses in the market offer a wider range of sizes.

Who we Recommend the Purple PurpleFlex Mattress for

  • Hot Sleepers: The Purple PurpleFlex mattress consists of a gel material that dissipates heat effectively. This mattress also comes with the SoftFlex Cover, which allows air to circulate due to its high breathability. These features, combined, contribute to a great cooling sensation, giving hot sleepers an enjoyable sleep experience.
  • Side Sleepers: The GelFlex Grid is known for its excellent pressure relief and body conformation. It is designed to contour to your body’s natural curves, especially around the hips and shoulders, allowing side sleepers to comfortably sleep without any pain.

Unboxing the Purple PurpleFlexMattress

The unboxing process for the PurpleFlex mattress was simple. It shipped compressed in a box, which we unpacked and started unrolling the mattress onto our sleeping surface. The mattress consists of a few layers, which are mainly memory foam, making it significantly lighter than most mattresses.

After unrolling the mattress, we left it for an hour to fully expand to its intended size. As for the edges, they inflated to their original shape shortly afterward. Indicating great corner expansion.

The PurpleFlex mattress did not give off a strong smell upon unpacking it. This is a result of the non-toxic materials used in making this mattress; the off-gassing period lasted only 2 days.

Firmness, Feel, and Comfort For Purple PurpleFlex Mattress

Purple PurpleFlex Mattress Firmness

The Purple PurpleFlex mattress scores an 8/10 on the firmness scale, which means it classifies as a firm mattress. This level of firmness will cater to the needs of various types of sleepers, which are mainly back sleepers and heavier side sleepers.

The PurpleFlex includes a base support foam that serves as the core support of the mattress, providing a base for the upper layers of the bed. This gives the mattress a more firm and supportive feel relative to Purple’s other mattresses.

Purple PurpleFlex Mattress Feel

The mattress has a distinctive and different feel with its grid-like design. This feeling appeals to some people and can be of great comfort to them. However, you get to try this mattress during your trial period to decide whether you like it or not.

Upon lying on the mattress, we felt the cool and soft surface of the mattress coming from the SoftFlex cover.

Purple PurpleFlex Mattress Comfort

The Purple PurpleFlex mattress provides exceptional comfort through its great ability to relieve pressure. It delivers great pressure relief, body contouring, and excellent cooling.

Sleepers of heavier body weights, especially stomach sleepers, will surely find comfort. The GelFlex Grid will seamlessly adapt to the body’s curvature, giving sleepers extra comfort and personalized pressure relief.

Later on in this review, we will be covering the pressure relief performance of the Purple PurpleFlex mattress.

Constructions, Materials, and Design

Materials and Design

The Purple PurpleFlex mattress features a layered design with its special GelFlex Grid, which is a gel-infused grid-like foam that effectively dissipates heat and provides pressure relief, helping you fall into deeper sleep stages.


Purple PurpleFlex mattress layers

  1. Soft Flex Cover: Purple PurpleFlex’s top layer boasts cool comfort with high breathability, lightweight materials, and stretchy adaptability. It conforms to your shape, enhancing GelFlex Grid performance and delivering a dynamic, cool sleep.
  2. GelFlex Grid: This layer contains a gel material that keeps the Purple PurpleFlex mattress temperature-regulated by dissipating heat away from your body. It is also known for its great ability to relieve pressure through its structure, which provides the perfect balance between support and comfort.
  3. Edge Support Foam: The edge support foam reinforces support around the edges of the mattress. This is great for people who like to sit or sleep on the side of the bed, preventing any roll-off sensation. It also enhances the durability and longevity of the mattress, allowing it to last a long time.
  4. Base Support Foam: This layer acts as the foundation and support core of the Purple PurpleFlex mattress. It provides a secure and stable base for the upper layers and evenly distributes weight across the mattress.

Performance of Purple PurpleFlex Mattress


The cooling performance of a mattress is crucial for hot sleepers or people who live in a warm climate. It will ensure the prevention of overheating during your sleep and will give you a more comfortable and restful night.

To perform our standard cooling test, we lie down on the mattress for 20 minutes, allowing the bed to absorb body heat, and then measure the mattress’s temperature.

During our test, we felt no notable amount of heat around the body, and there were no signs of heat buildup. The Purple PurpleFlex mattress features the GelFlex Grid, which contains a gel-like material that effectively withdraws heat away from the mattress. It also comes with the SoftFlex cover, which is made of a breathable material that allows for airflow.

We give the Purple PurpleFlex a score of 5/5 in our cooling performance test.


The responsiveness of a mattress indicates the time it takes for the mattress to adapt or adjust to your body’s movements, A mattress with a great response is important, especially for combination sleepers, as it will ease movement and prevent any stuck feeling.

For our responsiveness test, we use a 20-pound ball. Once fully rested, we measure how long the mattress takes to recover and retain its original shape.

While performing our test, the Purple PurpleFlex mattress reached complete recovery in 0.3 seconds, which is considered to be an excellent response time, knowing that the average response time is 0.4 seconds.

Overall, we give the PurpleFlex a score of 4.5/5 in terms of responsiveness.

Motion Isolation

A mattress that can effectively isolate motion is perfect for couples. This will allow you or your partner to get in or out of bed at night without waking each other up.

For the first test, we placed a glass of water on one side of the bed and dropped a 20-pound ball on the other to see how much the water moved around. With the PurpleFlex mattress, the water moved around slightly, which indicated the mattress did absorb motion, but not ideally.

In the second test, one person lay on the mattress while another rolled and moved around on the other side of the bed. The person lying at rest on the other side reported that they felt very little movement.

Although the GelFlex grid performs well at reducing motion on its own, it isn’t sufficient for the needed amount of motion isolation that most couples seek in a bed.

Therefore, the Purple PurpleFlex scored a 4/5 regarding motion isolation.

Edge Support

Edge support is crucial for a durable and long-lasting mattress. It increases its longevity and helps it maintain its structure for a long time. It is also a great feature for people who like to sleep or sit on the edge of the bed.

To test the edge support of the mattress, we applied firm pressure to the edges and felt great counterpressure levels from the mattress. When we released the pressure, the edges quickly sprang back into shape.

We also sat on the edges of the bed and could feel our weights sinking just slightly, but not too much. This is a great option for heavier sleepers and people who prefer to sit or sleep on the side of the bed. The PurpleFlex comes with Edge Support Foam, which reinforces the edges of the mattress and gives it more durability.

The Purple PurpleFlex scored 4.3/5 on our edge support tests.


A quiet mattress is essential for an uninterrupted and disturbance-free sleep experience. This is especially true for sensitive sleepers or partners who share a bed.

Our noise test is carried out by dropping a 20-pound ball onto the mattress. We then use sensitive microphones to listen for any noises or squeaks.

The Purple PurpleFlex bed excelled on our noise test by not showing any signs of noise, which is typical of an all-foam mattress. Mattresses with coils tend to make noise and squeak more compared to all-foam mattresses.

We rate the Purple PurpleFlex mattress a 5/5 on our noise performance test.


The sex performance of a mattress depends on its ability to provide edge support, good noise performance, responsiveness, and great bounce levels.

The PurpleFlex has a high level of bounce, which elevates the sex performance of this mattress. The edge support on this bed is good enough to not give you or your partner a roll-off sensation. It also maximizes the usable surface area of the mattress.

The GelFlex Grid, also known as the Purple Grid, is made of hyper-elastic polymer, which is highly responsive and will create ease of movement for more enjoyable intimate moments. This mattress has great noise performance, meaning it will not cause couples any kind of disturbance.

Overall, we give the Purple PurpleFlex a score of 5/5 in sex performance.

Pressure Relief

We carried out a pressure relief test on this mattress to see how it felt in different sleep positions.

Our standard pressure relief test is conducted by using a pressure mapping system to monitor the pressure levels throughout the body while lying on the bed. Below is an image that summarizes our results.

Purple PurpleFlex mattress pressure relief

The best results were showcased when performing the test on stomach sleepers. The pressure relief on the PurpleFlex mattress was good, and we felt great levels of pressure relief during our test. The GelFlex grid design helped contour the body’s shape, which helped relieve and eliminate pressure points.

However, despite the GelFlex Grid technology in the Purple PurpleFlex, we found that the mattress struggles to effectively eliminate pressure points for side sleepers, as opposed to its performance with stomach sleepers. This is mainly because the Purple PurpleFlex mattress is firm to side or back sleepers, especially lighter sleepers, potentially leading to discomfort during their sleep.

The GelFlex Grid Technology enhances pressure relief in the Purple PurpleFlex mattress by allowing it to effectively respond to pressure points where you need it most. The grid-like design helps distribute body weight evenly across the mattress surface. This eliminates pressure points in areas such as the shoulders, hips, and back.

The Purple PurpleFlex scored 4.5/5 on our pressure relief test.
