  • Not Weight-Inclusive: Designed for lighter weights, the Kids Purple Mattress features a soft, dual-layer comfort foam system ideal for children under 115 pounds. However, this weight limit may not be suitable for heavier children who might experience discomfort due to insufficient support.

Who we Recommend the Kids Purple Mattress for

  • Children Up to 14 Years Old: The Kids Purple Mattress is catered to the needs of growing children up to 14 years of age. It has a light and soft design that is designed to offer the perfect balance of support and comfort for your children’s smaller bodies. It has a dual-layer comfort foam system that ensures comfort and softness to your children’s sleep.
  • Parents Looking For a Safe Sleep Environment: This mattress includes a removable cover that can be machine-washed. This makes it easy to maintain a clean surface for your child, preventing the formation of mold or dust mites.

Unboxing the Kids Purple Mattress

The Kids Purple Mattress arrived compressed in a box. It did not feel as heavy as an adult’s mattress usually would, meaning you’ll be able to handle it and carry it on your own without external help.

We unrolled the mattress onto our sleep surface and monitored its expansion over time. The mattress expanded to its full size in around an hour. This is mainly because of the light design of the Kids Purple Mattress which only includes a dual-layer comfort system. The edges of the mattress expanded along with the whole mattress. Indicating great corner expansion.

Upon unpacking, the Kids Purple Mattress emitted minimal odor. Its Clean Air GOLD and CertiPUR-US certifications confirm it's crafted with non-toxic materials and produces low emissions. The off-gassing period lasted around 24 hours but could be shorter if placed in a well-ventilated space.

Firmness, Feel, and Comfort For Kids Purple Mattress

Kids Purple Mattress Firmness

The Kids Purple mattress has a medium-soft firmness, rating 5/10 on the firmness scale. This refers to the balanced feel that combines comfort and support.

This medium-soft profile allows the mattress to provide your children with the comfort and gentle plushness they need for their growing bodies. The GelFlex Grid adds a personalized touch to your child’s sleep experience by adapting to their body movements and pressure points. This mattress also includes a support foam that aims to maintain proper spinal alignment for a healthy sleep posture.

Kids Purple Mattress Feel

The top polyester cover of the Kids Purple mattress felt soft and cool against the skin. It’s made of cooling PE and polyester which together help maintain a temperature-regulated sleep surface.

The Kids Purple mattress is unique for its focus on providing a comfortable sleep experience for children. It includes Purple’s special GelFlex™ Grid which provides softness and a responsive sleep surface through its grid-like design.

Upon lying on the Kids Purple Mattress, we noticed the distinctive feel of the GelFlex™ Gird. We felt great body contouring and it adapted to the body’s pressure points, providing a personalized level of comfort.

Kids Purple Mattress Comfort

We ran a few tests to evaluate how comfortable the Kids Purple mattress is for kids of various ages and weights. Our aim is to understand how well the mattress provides comfort and support for a variety of kids, helping you make a precise decision for your child’s overall well-being.

In our tests, we noticed that the Kids Purple Mattress performed best for side sleepers, particularly those of younger age and lighter weight. The Purple GelFlex™ Grid provides exceptional support and comfort for side sleeping by relieving pressure in the hips and shoulders areas.

On the other hand, older children of higher body weights experienced less comfort, especially those who prefer sleeping on their back or stomach. Despite the support foam layer added to the Kids Purple mattress’s structure, its light design struggles to provide sufficient support for older children.

Here’s a table summarizing these results:

Later in this review, we will cover the pressure relief performance of the Kids Purple mattress.

Constructions, Materials, and Design

Materials and Design

The Kids Purple mattress is designed to offer a comfortable sleep experience for children. It is made up of multiple layers of materials, including the Purple GelFlex™ Grid, a hyper-elastic polymer material that features a unique grid-like design. This layer adjusts to your body movements, providing personalized pressure relief and a responsive sleep experience.

  1. Polyester Cover: This cover is made of a combination of polyester, cooling PE, and spandex. This set of materials helps provide durability, maintain temperature regulation, and give the cover extra stretch and flexibility.
  2. Purple Grid: This layer features Purple’s renowned Purple Grid which is a hyper-elastic polymer material. It is known for its distinctive grid-like design that offers support and comfort resulting in great body contouring. The Purple Grid also appeals to sleepers who enjoy a cloud-like or “on-top” feel. This top layer is coated in non-toxic polyethylene powder for enhanced durability and added protectiveness without compromising safety.
  3. Transition Foam: This middle layer is a density soft transition foam that offers a seamless and comfortable transition between the top comfort and bottom support layer. It also greatly contributes to the mattress’s responsiveness and movement adaptability.
  4. Support Foam: The base layer of the Kids Purple Mattress is a density medium support foam that serves as a foundational base and helps maintain the mattress’s structural integrity. In addition to enhancing the mattress’s durability, it also distributes the sleeper’s weight evenly across the mattress.

Performance of Kids Purple Mattress


The cooling effect of any mattress is crucial for a comfortable sleep environment for your children. This is particularly important for children who tend to overheat during their sleep.

We carry out our standard cooling test by lying down on the mattress for 20 minutes, allowing the bed to absorb body heat, and then measuring the mattress’s temperature.

reviewer sleeping in side position

The Kids Purple mattress did not showed any signs of body heat buildup and felt cool throughout the test.

This mattress features temperature regulation through the Purple GelFlex Grid which allows tons of airflow thanks to its open grid structure. This mattress comes with a cover made of polyester and cooling PE, making it highly breathable, moisture-wicking, and maintaining a cool sleep environment for your child.

The Kids Purple mattress scores 4.5/5 on our cooling performance test.


A responsive mattress allows for a more dynamic sleep experience. Your child should be able to comfortably enjoy their sleep without having their movement restricted.

During our responsiveness test, we used a 20-pound ball. Once fully rested, we measured how long the mattress took to recover and retain its original shape.

We noticed a fast response time of 0.4 seconds which is equal to the average response time of most of the mattresses we’ve tested.

The inclusion of the Purple GelFlex Grid in the Kids Purple mattress allows for high responsiveness by adapting to your child’s body movements. This will allow the sleeper to switch positions during the night without any trouble or stuck feeling.

The Kids Purple mattress scored a 4.8/5 regarding responsiveness.

Motion Isolation

Motion isolation is an essential aspect to consider in the Kids Purple mattress. This is particularly true for children who share the bed with their siblings, like in loft beds or bunk beds.

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 Kids Purple bed, the water did not move around much, which indicated that the mattress absorbed a sufficient amount of motion.

During our second test, we had one person lie down on the mattress while another person rolled and moved around on the other side of the bed. The person lying down on the other side reported that they felt a slight amount of movement.

The Kids Purple mattress is highly responsive, which means that it transfers a lot of movement. As a result, it can be challenging for the mattress to isolate motion effectively. If your child shares their bed with a sibling, this could have a negative impact on their sleep, as movements during the night are likely to disrupt their sleep.

We rate the Kids Purple Mattress a 3.5/5 in terms of isolating motion.

Edge Support

A mattress with supportive edges is designed to maintain its structural integrity and prevent any roll-off sensation on the sides of the bed. This feature is particularly important for kids' mattresses as children have a tendency to fall off the side of the bed more frequently.

For our edge support performance test, we applied firm pressure to the edges and were able to push alittle more to feel slight counterpressure from the sides of the bed. When we released pressure, the edges took some time to retain their original shape.

The Kids Purple mattress may not have the best edge support among other mattresses, mainly because it is a memory foam bed with a light and soft design. However, the GelFlex Grid enhances the support level across the mattress, providing your child with a consistent sleep surface.

For edge support, we give the Kids Purple mattress a score of 3.8/5


Noise performance is important in a kids’ mattress as children tend to be more light sleepers as opposed to adults. A quiet sleep environment is just what they need for restful sleep.

Our standard 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 Kids Purple mattress did not make any noises and we heard no squeaks at all. This mattress is a memory foam bed, meaning that these results were expected as hybrid mattresses with coil systems are more likely to produce noise and cause disturbances during sleep.

We rate the Kids Purple mattress a 5/5 for noise performance.

Pressure Relief

We evaluate the pressure relief performance of the Kids Purple mattress based on how it performs in different sleeping positions.

Our pressure relief test involves using a pressure mapping system to measure pressure levels throughout the body when lying on the bed. The results are summarized in the image below, where blue indicates lower pressure levels.

Kids Purple mattress pressure map

  • Back Sleepers: The pressure map showed moderate levels of pressure relief for back sleepers. It also displayed even lower pressure relief in kids of higher body weights. This is a result of the insufficient amount of support provided by the design and structure of the Kids Purple mattress for the lumbar region.
  • Stomach Sleepers: The pressure map showcased average levels of pressure relief. The Kids Purple bed’s soft design makes it a challenge to effectively elevate the hips and maintain proper spinal alignment for heavy children.
  • Side Sleepers: The pressure map revealed excellent pressure relief for side sleepers. The Purple GelFlex Grid contributed to these results by allowing the mattress to perfectly adapt to the child’s body shape and pressure points. It relieved tension in the hips and shoulders, eliminating any pressure points in those two areas.
