Soaring Heart makes an unusually focused group of natural beds: a 6-inch latex mattress, two foldable futons, and a 3-inch shikibuton. Prices currently start between $1,149 and $1,899, depending on the model and size. The materials stay simple—organic latex, cotton, and wool—but the feel changes considerably across the lineup. The latex mattress offers the strongest all-night support, the latex-core futon is the most forgiving multipurpose option, and the fiber-only designs suit people who genuinely prefer a firm, low-profile bed. All four sleep cool, but none delivers the deep cushioning of a plush foam or thick hybrid mattress.

Which Soaring Heart Bed Should You Buy?
Organic Latex Mattress. This is the clear choice for everyday use. It kept the hips level, responded quickly when we changed position, and held less heat than dense foam. Back and stomach sleepers will get the most from its firm, flat support. Side sleepers with sensitive shoulders will probably need a topper.
Organic Cotton Latex & Wool Futon. Choose this for a room that shifts between sitting and sleeping. Its latex core adds enough give to feel more like a compact mattress than a stuffed pad, and it handles a sofa-frame crease better than the fiber-only futon. It remains heavy and has a less defined edge than a conventional mattress.
Organic Cotton & Wool Futon. This model makes sense for a guest room, lounge, or sleeper who actively wants a very firm surface. It feels stable and breathable, but the frame underneath has a strong effect on comfort. For regular side sleeping, a topper is the most direct way to make the surface softer.
Organic Cotton & Wool Shikibuton. The thinnest model works best as compact guest bedding or a minimalist bed on a breathable raised base. It folds more readily than the thicker futons and transfers very little movement, but its 3-inch profile leaves little room for pressure relief. It is not our pick for daily side sleeping or for heavier sleepers.

How We Evaluated These Beds
Marcus Reed, Mia Chen, and Ethan Cole used each model for overnight sleep and daytime lounging. Their different builds and sleep styles helped expose where a bed's feel changed: Marcus runs hot and carries more weight, Mia is a pressure-sensitive side sleeper, and Ethan changes position frequently. Along with comfort notes, our process for testing mattresses included loaded sinkage, surface-temperature change, movement at the opposite side of the bed, recovery after weight removal, and edge compression. We also used our standard pressure-relief checks. Every category uses the same 5-point scale.
Soaring Heart Mattress: Our Testing Experience
Organic Latex Mattress
Our Testing Experience

The Organic Latex Mattress felt firm from the first night, but the support was even rather than rigid. Our sample measured 6 inches and landed at 8 out of 10 for firmness. Under a 200-pound simulated load, the center compressed 1.4 inches, enough to settle the hips without letting them drop below the torso. That balance worked especially well for back and stomach sleeping. Mia felt concentrated pressure at her shoulder on her side, while Ethan could turn without pushing off with his arms; the latex returned to 90% of its original height in 0.7 seconds. After 30 minutes, the surface temperature rose 4.1°F, a modest change that matched Marcus's cool-sleeping impression and a familiar advantage when comparing memory foam with latex.

Latex-Core Futon
Our Testing Experience

This was the easiest futon in the group to use as both a sofa and a bed. Our sample had settled to 6.4 inches and felt like 6.5 out of 10 for firmness. A 150-pound load compressed the center 1.7 inches, giving the ribs and hips more room than the fiber-only futon without creating a deep cradle. The fold line was noticeable in sofa mode but did not remain as a hard ridge after the bed was opened flat. Recovery to 90% height took 1.2 seconds, so Ethan could change positions without fighting the surface. The temperature increase after 30 minutes was 4.6°F. Mia still wanted more shoulder relief, but this was her preferred futon by a clear margin.

Cotton & Wool Futon
Our Testing Experience

The Cotton & Wool Futon has the dense, flat feel people expect from a traditional fiber futon. It measured 6 inches and registered 8.5 out of 10 for firmness. With a 150-pound load, the center sank 1 inch; that limited give kept our hips steady on our backs but created pressure at the shoulder during side sleeping. The surface warmed by 5.1°F after 30 minutes, still a good result for a tightly packed bed. Recovery to 90% height took 2.7 seconds, noticeably slower than either latex model. The frame mattered just as much as the futon: closely spaced, rigid slats felt stable, while wider gaps became obvious under the torso.

-
What we liked

Feels stable when paired with a rigid, closely spaced base
-
Uses breathable fibers without a foam component

Cotton & Wool Shikibuton
Our Testing Experience

The 3-inch Shikibuton was the most sensitive to its support surface. On a breathable raised base it felt even and secure, but it offered almost no buffer against an uneven foundation. Firmness measured 9 out of 10, and a 44-pound load produced just 0.6 inch of sinkage. That explains both its steady back-sleeping feel and Mia's quick buildup of shoulder pressure. In the motion test, vibration faded in 0.5 seconds, the best result in the group. The surface temperature rose 4.8°F after 30 minutes. It folds into a smaller package than the two thicker futons, but it is still a full-size, densely filled bed rather than a lightweight mat.

-
What we liked
-
Has the lowest profile and smallest folded footprint in the group
-
Controls movement exceptionally well
-
Cotton and wool keep the surface from feeling clammy

-
Who it is best for

-
Its thin profile creates pressure quickly for side sleepers
-
Heavier sleepers get too little cushioning for nightly use
-
It needs ventilation underneath and should not stay directly on the floor

Performance Scores
| Mattress | Overall | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness |
|---|---|---|---|---|---|---|---|
| Organic Latex | 4.3 | 4.7 | 3.8 | 4.4 | 3.9 | 4.7 | 4.5 |
| Latex-Core Futon | 4.0 | 4.1 | 3.7 | 4.2 | 4.0 | 3.8 | 4.1 |

The Organic Latex Mattress is the strongest all-around performer, led by support, durability, and fast response. The Latex-Core Futon gives up some long-term stability but is the better choice for a room that needs a foldable bed. The two fiber-only models are more specialized: both stay cool and limit motion well, but their thin, firm builds trail the best pressure-relief mattresses.
Finding the Right Soaring Heart Model
Start with sleep position and your preferred mattress firmness. Back and stomach sleepers benefit most from the flat support of the Organic Latex Mattress. Side sleepers need more surface give, which makes the Latex-Core Futon the better match among these four, though a topper may still be necessary. Body type matters as well: the thinner fiber beds bottom out sooner and reveal more of the base underneath.
Next, decide whether the bed will stay flat or switch into a sofa. For a primary bedroom, the Organic Latex Mattress is worth the higher cost because it has the most consistent support and the best durability score. For a sofa frame, the latex-core futon manages the fold better than the cotton-and-wool version. The Shikibuton is the most compact choice, but it still needs a ventilated raised surface rather than prolonged direct contact with the floor.

How Soaring Heart Compares
Soaring Heart stands apart through simple, foam-free or all-latex builds and foldable formats. Its models suit buyers who want firm support, breathable natural fibers, and fewer layers. They are less suitable for shoppers who want a plush surface, a reinforced perimeter, or the taller feel of a modern hybrid.
Avocado Green Mattress. Avocado's Green is the stronger latex-hybrid alternative for someone who wants organic latex and wool with an innerspring support unit. It is taller, has more pronounced edge structure, and comes in several comfort levels, including a pillow-top Plush option. That broader feel range is better for couples with different preferences and side sleepers who need more cushioning, while Soaring Heart's Organic Latex Mattress feels simpler, flatter, and easier to move on.
Naturepedic Latex-Free Serenade. Formerly called the Chorus, this mattress replaces latex with microcoils and encased support coils under organic cotton and wool. It offers more contouring and the kind of perimeter stability associated with the best edge-support mattresses, while preserving a buoyant, foam-free feel. It also includes a 100-night trial and 25-year limited warranty. Choose it if latex sensitivity or a conventional mattress shape matters more than Soaring Heart's foldability.
Care and Setup Tips
-
Use a rigid, breathable platform bed or frame. Closely spaced slats reduce sagging and keep moisture from collecting underneath.
-
Do not leave a cotton or wool futon directly on the floor. If you place it there temporarily, air it thoroughly and return it to a raised base.
-
Flip and rotate the futons and Shikibuton regularly. The brand recommends weekly care during the Shikibuton's first month, then every other week.
-
Add a topper rather than a pad for side sleeping instead of expecting a fiber bed to soften dramatically.
-
Use the latex-core futon for a sofa frame; it recovers from the fold more cleanly than the fiber-only version.
-
Protect the surface with a breathable mattress pad that can be washed and dried completely.
FAQs
Is the Organic Latex Mattress too firm for side sleepers?
For many side sleepers, yes. It supported the torso well, but its 8-out-of-10 feel left limited room for the shoulder to sink. A pressure-sensitive side sleeper should plan on a topper or consider a softer mattress.
Which futon works better on a sofa frame?
The Organic Cotton Latex & Wool Futon. Its latex core reduces persistent creasing at the fold and gives the bed a faster, more even recovery when it is opened flat.
Can the Shikibuton work for everyday sleep?
It can work for a lighter back sleeper who genuinely prefers a very firm, low-profile bed. Most side sleepers and heavier sleepers will need more cushioning. It also requires a breathable raised surface and frequent flipping and rotation; leaving it directly on the floor increases the risk of trapped moisture.
