Kids Mattress Benefits
Flippable Benefits Icon
2-Sided Design for Growing Kids
8" hybrid mattress with 6" innersprings and custom foam layers to provide the right safety, comfort, support, and durability for growing kids with changing needs and preferences.

Firmer Side Benefits Icon
Firmer Side
The firmer side is great for younger kids (suggested for 3-7 year olds) when they need additional support to aid proper development of their growing bodies.

Softer Side Benefits Icon
Softer Side
As kids get older, they tend to favor mattresses with more of a comforting feel, which is why we created a softer side for older kids (suggested for 8-12) that still provides excellent support.

Sleep Safely Benefits Icon
Sleep Safely

To ensure your kid won’t be exposed to dangerous chemicals, this mattress was tested for lead and phthalate and all foams are CertiPUR-US® certified, which guarantees they were made without harmful chemicals. Made without fiberglass.

As your child outgrows their crib mattress, they’ll need a bit more space. The Helix Kids Mattress offers Twin and Full size mattresses that provide the perfect transition from a crib mattress for young children. Unlike a crib mattress, which is often made to be very firm, the Helix Kids Mattress also is designed with two distinct sides that provide optimal comfort and support for children’s growing bodies. 

Absolutely - the Helix Kids Mattress is kid tested and approved! Our softer side of the mattress is made with high-density memory foam that provides excellent contouring and comfort. Our firm side of the mattress is made with high-density Helix Responsive Foam for optimal support and cushioning. The Helix Kids Mattress is made to be great for both side sleepers who like a soft mattress and children who might prefer a firm mattress.

The Helix Kids Mattress is both GREENGUARD Gold and CertiPUR-US certified, ensuring our foam layers are constructed without the use of harmful chemicals including ozone depleters, PBDE flame retardants, mercury, lead, heavy metals, or formaldehyde.

The Helix Kids Mattress is also Lead and Phthalate tested, flammability tested, and includes a cutting-edge AEGIS® Microbe Shield treatment that offers optimal freshness and hygiene for the life of this Helix mattress. Learn more.

The Helix Kids Mattress is designed to provide the perfect support and safety for your child as they grow and their sleep preferences change.

One side features a firmer feel that provides more spinal support to aid proper development for younger kids in the estimated age range of 3-7. If it feels a bit too firm for your child, just flip it over and they can enjoy a bit more plush comfort and pressure relief which we suggest for kids in the estimated age range of 8-12. Learn more.

Unboxing Your Helix Kids Mattress
Helix Kids unboxing illustrations

Your Helix Kids Mattress will be delivered in a sturdy box and wrapped in two layers of airtight plastic. 

To get started, bring your boxed Helix Kids Mattress into the bedroom and open one end of the box. Lay the box on its side and remove the rolled up mattress, placing it directly on your child's sleep surface. Set aside the empty box to be recycled later. 
Helix Kids unboxing illustrations

To remove the outer layer of airtight plastic, pull on the tab and begin removing the entire outer layer. You are welcome to carefully use scissors to cut away the outer layer of plastic if necessary. Your mattress may begin to unroll or unfold on your child's sleep surface. 

Once the outer layer of plastic has been fully removed, please set it aside. It can be recycled with soft plastics if that service is available in your area.
Helix Kids unboxing illustrations

With the outer layer of plastic removed, fully unfold your child's mattress so it sits flat on your child's sleep surface, with only one layer of airtight plastic remaining. 

Carefully cut the inner layer of recyclable plastic (avoid cutting the mattress) and remove it. As you cut into the inner layer of plastic, the mattress will begin to rapidly expand.
Helix Kids unboxing illustrations

Flip the mattress so the age range that appears right side up (on top) is appropriate. 

Please give the mattress 1-2 hours to expand. Once fully expanded, your Helix Kids Mattress will measure approximately 8 inches tall. Then it's time to kick back and relax. Sweet dreams!
