Birch by Helix: It is a Bed in a Box
The 11-inch-thick Birch model is a “bed in a box,” which is a popular concept for a good reason. Essentially, bed in a box means that it is available only online and ships directly to your home.
The chief benefit here is that you have time to try out the Birch Organic Mattress in what is called a “sleep trial” over a series of nights in your home, rather than only a couple of minutes in a mattress showroom. Furthermore, there are no salespeople hovering over you as you test out the bed.
For Birch, the sleep trial is 100 nights, which is a generous amount of time to see if it’s the right bed for you. In the unlikely case that you’re not happy with it, simply ship it back and receive a full refund.
In other words, there is no risk in trying this mattress to see if it can provide you a deep sleep. It even comes with a lengthy 25-year warranty.
Firmness of the Top Rated Organic Mattress
This Birch Organic Mattress has a medium-firm feel, according to several reviewers online. On a scale of 1-10, where 10 is the firmest, many users rate it as 6.7 or 7.
A medium firmness provides the best of both worlds in many ways; it is both comfortable and has resiliency. Firstly, the firm feel offers support as you rest on it, which is terrific if you have sore points, such as an aching back or shoulder.
Secondly, the comfort comes from the bouncy quality of this all-natural mattress. It has enough spring that it is cozy, all without bouncing so much that it’s hard to get off and on. As one reviewer explains, it is like resting on a cloud that has a bit of spring to it.

A Hybrid Mattress: What Does That Mean?
As a “hybrid,” the bed features memory foam overtop core of individually wrapped coils. The comfort discussed earlier comes from the top layer of natural and organic wool, as well as the layer beneath that of natural Talalay latex that comes from a tree source.
This latex is what provides that bounciness we described in the last section of this Birch Organic Mattress review. As for the wool, it is naturally flame retardant for one of the safest fibers available if a fire were to occur in your residence.
Not only that but the wool also provides a spring to help the mattress retain its shape for a mattress with a long lifespan. The fibers are quite durable.
Below the cozy layers are supportive coils; Birch has both lower-gauge and higher-gauge coils. This hybrid style is terrific for side, back, and combination sleepers, all of whom provide positive web reviews for the bed.
The lower-gauge coils help prevent the mattress edges from sinking with use and time, so that it is longer-lasting and durable. Meanwhile the higher-gauge kind sit directly underneath the body, gently supporting your pressure points, such as hips, shoulders, and lower back.
Finally, at the base layer is wool batting that is both organic and natural. This batting is highly sustainable and is made dense to provide great support.
Tip: Birch offers a long up to 25 year warranty plan. Check it out.

All This and Sleeps Cool Too
In addition to having several green certifications to its name, the Birch top rated organic mattress also is highly breathable. The design and type of materials enable a cool sleep for a deep slumber.
The New Zealand Wool within the mattress naturally wicks away sweat, which is great for a hot sleeper. Otherwise, you might sweat during the night and a rise in body temperature often is enough to wake you up if you’re like most people.
This wool is a natural temperature regulator. Not only that but the top layer is highly breathable to encourage a cool sleep surface against your body.
All of which adds up to an uninterrupted sleep. A good rest makes for a feeling of satisfaction and alertness the next morning as you take on the new day.

From the durable wool fibers to the supportive coils and soft organic cotton, this model is among the leaders in our eyes for the title of top rated organic mattress. Whether you are an environmentally-conscious shopper or seek a mattress that is cozy while also supportive, the features of the Birch model are sure to appeal. We recommend it highly.
