When it comes to your child's sleep, they shouldn’t have to settle for good enough. We’ve gone above and beyond to provide the age-appropriate comfort they deserve.
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
The firmer side is great for younger kids (suggested for 2-7 year olds) when they need additional support to aid proper development of their growing bodies.
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 & up) that still provides excellent support.
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.
"A mattress may not be exciting to a
kid, but they will thank you when they
sleep like a baby (no pun intended).
And, parents will love it too."
"Helix has a new kids mattress
and you're going to want to check it out!
It has all sorts of thoughtful features that
help facilitate a good night’s sleep."
"New & Notable: The Helix Kids Mattress
sports a dual-sided design so your
kid can switch it up as they grow and
their preferences change."
Trusting us to help your kids get a great night's sleep is a big deal, so we turned to experts and professional caregivers to test our mattresses. That's right, in addition to kids and parents trying out the Helix Kids Mattress, we've also turned to medical doctors, pediatric sleep specialists, and child & family sleep consultants to test this mattress.

Who knows best? Moms and dads, of course! But because we designed this bed for kids, we knew we had to also ask them what they thought about the Helix Kids Mattress. So in addition to our mattresses getting tested by medical doctors, pediatric sleep specialists, and child & family sleep consultants, we also got real kids and real families to try out our mattresses too!

What makes a child’s mattress different from a crib mattress?
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.
Is this child’s mattress actually comfortable?
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.
Does the Helix Kids Mattress have any safety certifications?
The Helix Kids Mattress is GREENGUARD Gold certified and made with CertiPUR-US® certified foams, 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.
Why are there two sides to the Helix Kids Mattress?
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 2-7. 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 & up. Learn more.
