Let’s dig into what makes the Birch Kids one of the most highly sought after Natural Mattresses for Kids:

Birch Kids Construction & Materials

Birch Kids Natural mattress layers
The Cover & Fire Retardant Layer

Birch Kids starts with a hypoallergenic ultra soft 100%All Birch Luxe mattresses contain organic cotton pictured in this cotton image certified organic cotton cover.  Cotton is one of the softest, most breathable and most comfortable fabrics available. It’s cool, wicks moisture and, better still, is more sustainable.  The cover is followed by a layer of Birch’s organic wool and naturally made rayon fibers for a completely chemical-free retardant layer.  Additionally, wool is naturally antimicrobial and wicks away moisture providing freshness and natural cooling properties.

Comfort Layers

Birch designed their Kids mattress to beBirch Kids is flippable for best comfort for growing kids flippable so different age groups can take the most advantage of the mattress.  This differentiation occurs in the comfort layer.

Ages 3-7 Side: This side is firmer for additional support and to promote proper spinal alignment.  Directly beneath the cover lies the natural wool fire barrier, free from any chemicals or fiberglass.  Below the fire barrier Birch puts down a layer of firm Dunlop Latex.  This durable latex provides ergonomic support and contour, designed to dampen motion transfer and allow further support for growing kids.

Age 8-12 Side:  On the flip side, beneath theBirch sources its latex from Indian rubber trees and the final product looks like the latex pieces on the right fire barrier, Helix lays down plush layer of Dunlop Latex.  By layering a plush latex the Birch Kids provides pressure relieving comfort Helix has struck the perfect combination to match the big kids’ sleeping style. Why latex? Latex naturally absorbs moisture and pulls away heat from the body. It keeps them cool throughout the night so they achieve the maximum benefits of sleep. Sandwiched in-between the comfort layers is Helix Kids coil support system.

Birch sources rubber exclusively from closely monitored plantations and the resulting latex foam is produced in the US. The latex foam is both GREENGUARD Gold and eco-INSTITUT certified to ensure high quality and safety standards. Additionally, the forests and plantations we source our latex from are also certified by the Forest Stewardship Council and Rainforest Alliance.

Support System

The robust 5 zoned spring coil support that comes with every Birch Luxe latex hybrid mattress will provide superior support throughout the life of the mattress.

Birch Kids’s support system employs 6″ triple tempered steel individually pocketed coils sandwiched in-between the comfort layers. This high grade steel provides superior support throughout the life of the mattress.  Helix uses stronger gauge steel around the perimeter to ensure greater edge support.

Finally, a second fire retardant base layer made of organic wool and rayon keeps your little one safe while providing stability and durability to the entire mattress.


Tufting is the process where the individual parts of the mattress are either sewn or glued together to prevent slippage.  In Birch’s case, they chose top tufting, where the cover is sewn into the latex layer.  Tufting helps keep everything nice and together.  This is just another example of the little details Birch takes care of so you can rest easy.

Does Birch Kids Sleep Cool?

Yes!  Birch Kids has several mechanisms to give your littleBirch Kids has two sides providing different comfort for growing kids one a cool, dry and comfortable night sleep.  Feeling cool at night is all about feeling dry.  Birch Kids starts with the ultra wicking cotton cover and moisture absorbing wool which not only wicks moisture, but they improve airflow.  Latex is naturally cool and Birch perforates it to increase airflow.  And finally, the hybrid has springs which further promote air flow.  The result, a cool dry sleep all night long.

How about Edge Support?

Very Good: Birch reinforces the outer edge of the spring support system with thicker coils on every mattress.  This results in a stronger edge support allowing kids to sleep all the way to the edge with no worry of sliding off.  

Birch Kids Comfort & Feel

Birch Kids mattress is specially designed for kids age 3-12.  But as kids age, their sleep support system needs change.  Birch took that into account when building the Kids mattress, making it durable and flippable for when the time comes for a comfort change, without sacrificing the support growing bodies need.  We’ll detail out how the two sides feel below.

No matter which side, your child will start off on a soft yet breathable hypoallergenic organic cotton cover.  This cooling, naturally anti-microbial fabric ensures that your child will be sleeping on a soft comfortable bed.

Age 3-7 Side: This is the firmer side.  Ideally designed to support the spine and promote proper posture, the denser latex selection provides additional support where the child needs it most.  Shortly after laying down, your child will feel the springs begin to support and cradle their body.  While firm, the surface is not “hard” and they will be receiving plenty of support that they need.  Your child will sleep more “on-top” of the mattress as opposed to “in” the mattress.

Age 8-12 Side: Flip the mattress when your child is big enough to want more comfort from their mattress.  The plush latex layer adds a touch of sink.  As their body grows, their comfort needs change as pressure points develop if the bed is too firm.  The cooling latex helps relieve them and keep them cool so they get the rest they need.  They will still sleep “on top” of the mattress, but will definitely have a little sink to contour where they need it most.

Regardless of the side, your child will have 6 inch coils for enhanced support for years to come.  When they outgrow the 8-12 side, they can look towards the popular Birch  Mattress for additional comfort and support.

The sweet spot for weight is up to 100 lbs.

  • On Sandman’s Firmness Scale, we rate Birch Kids a 6.5 out of 10 on the firmer side and a 5 out of 10 on the softer side.
  • Designed to support growing kids, all sleep positions are supported.
  • Even with a little bit of sink, the superior airflow design and advanced cooling technology will keep your kid cool and dry all night long.
  • Edge support is excellent – no side sagging here!

Extra Safety Standards

How does the Birch Kids arrive?

Image of the Birch luxe mattress that is shipped and delivered in a boxBirch Kids comes in a box for easy shipping and moving to the bedroom. It’s crazy to think that a mattress with powerful springs and dense latex can be compressed, but it can.  And, with no sacrifice to quality and durability.  Some people ask if compressing the springs hurts their integrity.  Nothing could be farther from the  truth.  Springs are actually shipped compressed all over the world (to save space).  The springs integrity is damaged when they are pulled excessively or bent out of position.  But, the way Birch compresses its mattresses, they keep their shape and strength. 

The box arrives via FedEx.  Simply unbox the mattress.  Rest it on the bed frame and remove the plastic wrapping and the bed will decompress before your eyes.  Your child can begin sleeping on the bed and enjoying a restful night sleep that same day.  Moving most sizes will be a 2 man job, especially if going up stairs.  Check out the Dimensions below for more details.

What is Birch's Return Policy?

Every Birch Luxe Mattress comes with an industry leading 25 year warranty

Birch offers a 100 night trial period, giving your child over 3 months to test out the mattress.   You can either return it for a 100% refund, minus a $99 return shipping fee.  It truly is hassle free as Helix does all the heavy lifting.  Here’s how both systems work:

  1. The trial begins when you RECEIVE the mattress (the fedEx delivery day).
  2. Your child can sleep on it for 100 nights.  As there can be a slight break-in period, Birch asks that you not initiate a return during the first 30 days.  
  3. If it’s not the mattress of your child’s dreams, reach out to Birch via phone, email or chat (on their website), provide your name and order number and let them know if you wish to start a RETURN.  There are no questions asked!
  4. Birch coordinates a donation or recycling pickup on a day of your choosing.  They handle everything and there’s nothing you have to do besides letting them know the best pickup date.
  5. Full 100% refunds (minus a $99 return shipping fee!!) are issued within 5 days of the pick-up.
