How the Helix Kids Mattress is Made

The Helix Kids mattress is made with comfort and safety in mind. From the hypoallergenic cover to the contouring and support layers, you can read the construction details below.

Hypoallergenic Cover With Antimicrobial Shield (Firmer Side)

The entire mattress is enclosed in a breathable, hypoallergenic cover. The soft TENCELTM fabric is treated with a plant-based water-repellent finish and AEGIS antimicrobial shield..

Non-Fiberglass Fire Retardant

A flame-retardant layer provides crucial protection while kids sleep. The material is fiberglass-free and certified free of toxic chemicals.

Helix Responsive Foam Support (Firmer Side)

This layer of dense, sturdy foam provides support on the firmer side of the Helix Kids mattress. The Helix Responsive Foam supports the spine with a slight amount of cushioning.

Body Shape Coils

A 6” layer of individually wrapped coils offer support and pressure relief. Hundreds of coils adapt to your child’s shape, creating a cradling effect and limiting motion transfer. The two reinforced sides provide edge support and help keep your child safely on the mattress.

Gel Memory Foam (Softer Side)

On the softer mattress side, gel memory foam cushions and contours to the body. It’s one more layer of pressure relief and plush comfort.

More Fire Retardant

Once again, nontoxic, fire retardant layer provides protection against flammability. The side panels of the mattress are also protected by this fiberglass-free material.

Hypoallergenic and Water Repellant Cover (Softer Side)

The soft side of the Helix Kids mattress has the same hypoallergenic, antimicrobial cover as the firm side and the entire mattress. The water-repellant TENCEL fabric keeps the mattress surface fresh and stain-free.

Choose a Size to Fit Your Child

The right mattress size will provide a comfortable sleep surface as kids grow. The Helix Kids mattress is 8” thick and is available in two standard mattress sizes:

  • Twin: 38” x 75”
  • Full: 54” x 75”

Check Sizes’ Price

Helix notes on their website that dimensions may vary up to 2” on any side because the mattresses are handmade.

Two Firmness Levelsin One Mattress

The Helix Kids mattress has two firmness levels in one mattress to accommodate a child’s evolving sleep preferences. The firmer side of the mattress has a rating of 6-7 on a scale of 1-10, with 10 the firmest. The softer side of the mattress is rated 4-5.

Helix Kids Mattress Review: Pros and Any Limitations

Now that you know what goes into the Helix Kids mattress, let’s take a closer look. After our research and review, we share what we believe are its pros as well as any limitations.

Choice of Two Firmness Levels

With two firmness levels, the Helix Kids mattress is designed for a child’s changing sleep needs. The Helix website recommends the firmer side for ages 3-7 years and the softer side for ages 8-12 years.

Personal preference is often the deciding factor for the ideal firmness level, no matter what age. If your child sleeps on their side, the softer surface is a good option. For stomach and back sleepers, the firmer side prevents the midsection from sinking too low.

Pressure Relief

A layer of gel memory foam provides a plush, cozy feel on the softer side of the mattress. It contours to your child’s body and provides much needed pressure relief after an active day.

We think that side sleepers will especially like the cradling effect for the shoulders and hips. As it contours, the memory foam helps support helps keep the spine in proper alignment.

The individually wrapped coils add support and more pressure relief as they adapt to a child shape and changing sleep positions.

Support

On the firmer side, high-density Helix Responsive foam provides the support needed for a younger child’s growth and development. The wrapped coils add just enough pressure relief to maintain comfort. For back and stomach sleepers, the firmer side supports the spine by preventing a child’s midsection from sinking too low.

Hypoallergenic and Antimicrobial

The Helix Kids mattress cover offers hypoallergenic protection. And that not all. The TENCELTM fabric is made with a plant-based water repellent treatment and antimicrobial shield. Plus, the fabric is breathable to keep things cool and comfortable. You and your child can rest easy as this innovative cover keeps stains, moisture, allergens and odors away.

Temperature Regulation

Thanks to temperature regulating features, the Helix Kids mattress won’t overheat. It starts with the soft, breathable cover and continues with the individually wrapped coils. Air circulates throughout the mattress, carrying away body heat. That means your child can wake up cool and dry instead of hot and sweaty.

Nontoxic Flame Retardant

A non-fiberglass flame retardant shields the mattress from flammability. The Helix Kids mattress passes dual flammability testing and is certified free of harmful chemical flame retardants. You can have peace of mind knowing that your child is protected from fire without the use of toxic chemicals.

Certified Free of Harmful Chemicals

Your child’s safety is the first priority, so we think you’ll appreciate that the Helix Kids mattress meets safety certification standards. It’s Certi-PUR-US and GREENGUARD certified, which means that the foams do not contain harmful chemicals or heavy metals such as formaldehyde, mercury or lead. The mattress is specifically tested to ensure that it is free of lead and phthalates. Its low emissions make it safe for indoor air quality, too.

Mattress in a Box

With today’s busy schedules, convenience is a definite plus. When you buy a Helix Kids mattress, it’s compressed, rolled and shipped in a box to your door. Even if you’re busy taking the kids to soccer practice or piano lessons, the mattress will be waiting at your door when you get home.

The mattress takes up to two hours to fully expand after unboxing, so it’s not immediately ready to use. You may want to air out the mattress due to a slight, harmless odor that should dissipate within a week.

100-Night Trial

It’s hard to know immediately if a mattress is right for your child. That’s why the Helix Kids mattress comes with a 100-night trial. Your child can try the mattress at home for more than three months to make sure it’s a good fit. If the mattress just isn’t working for your child, you can return for a full refund it within 100 days, after a 30-day break-in period.

Limited Lifetime Warranty

The Helix Kids mattress comes with an impressively long Limited Lifetime Warranty that covers damage from manufacturer defects. Even the best mattresses for kids can have occasional issues. The company will repair or replace a mattress that is found to have defects covered by the warranty.

Always check the warranty terms before you buy a mattress, as coverage can change at any time.

Concluding Thoughts on the Helix Kids’ Mattress Review

The Helix Kids mattress is built to accommodate a child’s sleep needs. With two firmness levels in one mattress, it can keep up with growth and evolving preferences.

For developmental support, Helix recommends the firmer side of the mattress for younger children and the softer side for older kids. The two firmness levels can also accommodate a child’s changing sleep preferences at any age.

Your child can sleep cool and comfortable as the breathable cover prevents the mattress from overheating. The cover also has hypoallergenic, water-repellent and antimicrobial properties.

We applaud the safety features of this mattress, including CertiPUR-US and GREENGUARD certifications. The mattress has a nontoxic flame retardant and passes dual testing for flammability.

The mattress is conveniently shipped in a box, which is helpful for busy parents. A minor inconvenience is the 2-hour wait for the mattress to expand, and the odor that usually dissipates within a week.

We like the 100-night trial and Limited Lifetime Warranty that come with the Helix Kids mattress. When shopping for the best mattress for kids, it helps to know that a company stands by their product in this way.

After our research and review, our team believes that the Helix Kids mattress offers value. In our opinion, it is a quality mattress for children.
