  • When we say all natural and organic, we mean it. Since 1982 Soaring Heart Natural Bed Company has been making mattresses and bedding using time-tested techniques, honed and polished over three decades. Soaring Heart makes everything by hand and uses only the highest quality, certified organic, materials available.

    Soaring Heart works closely with our suppliers.  We travel to their operations, getting to know them and their materials.  We collaborate with our suppliers so we can meet and exceed our exacting standards. We take huge pride in our products and in all the people behind them.

    It's because of these special relationships with our suppliers and their wonderful organic wool, organic latex, organic cotton and their commitment to upholding organic certifications that we aren’t forced to spoil our products with chemicals or synthetics. No Soaring Heart product has any chemical-based foam or synthetic fire retardants whatsoever.

    Our latex is made from pure rubber tree sap.  We use organic wool as our fire barrier, and it is selected from only the finest sheep farms in New Zealand.  Our cotton is 100% organically grown in the cotton fields of Texas. Nothing but good, honest organic materials provided by good, honest people.

    We are very proud that our latex used in mattresses, pillows and more is >95% organic; GOLS certified.


  • Caring for a Soaring Heart Organic Latex Mattress is easy.

    • Keep your mattress on a slatted bed frame off the ground. This provides proper ventilation, stopping moisture buildup.

    • Flip your mattress every 3 to 6 months.

    • Always use a mattress pad. The mattress pad protects the mattress from body moisture, spills and accidents. You can clean a mattress pad, you can't clean a mattress.

    For more care instructions and tips, visit our Care page.

  • Does the mattress need to be on a slatted frame?

    Our 100% Dunlop Latex Mattress needs air circulation. Whether that is in the form of a slatted frame/ foundation or Tatami Mats, we ask that you keep the mattress off the floor and prevent it from getting wet and staying wet.

    How long does the mattress usually last?

    Not only is Dunlop latex extremely resilient and flexible, it is also designed to be sturdy for long periods of time. Most of our mattresses really do last for 20+ years without taking an impression and customers are overjoyed with their purchase.

    When you say “Firm”, what does that exactly mean?

    Our Firm Latex Mattress has an ILD range (Indentation Load Deflection) of 28-32. This is the industry standard for a Firm Mattress. Most average size adults find the Extra Firm Mattress to be too firm and the Soft to have too much of a sinking feeling which is why suggest adding a topper to the mattress to find your perfect comfort zone.

    How often does the warranty get exercised by customers?

    It is exceedingly rare for our latex to leave an impression in the 20 year period in which it is warranted. Our Logistics Manager, Jeff Greenwood, has been working at Soaring Heart Natural Beds for 10 years and has rarely seen a mattress take an impression.

    “In the time I have spent here, I can only point to a handful of times in which the warranty has ever been exercised on a firm latex mattress and in those times the issue was either very small or undetectable”  - J. Greenwood

The Rowan in size twin

Excellent product. I had a 30-year-old soaring heart futon that needed to be replaced. Since getting this product my neck pain and hip bursitis has resolved. No more Advil. Gotta love that.

The BEST Rest!

I found my bed at Soaring Heart BEFORE I even had my apartment secured after moving to Seattle. The Ballard store staff - Sierra and Lith - are amazing. They let me try the different mattresses and worked with me when I had housing delays. I am so supremely happy with my mattress and frame. It is so restful and healing to have an organic natural sleep system. Thanks Soaring Heart.

Sleeping in Tacoma

It has been almost 20 years since we have slept well and on a new mattress. I have slept deeply on our latex mattress with topper and protective cover. No more electric mattress heat either. The bed warms up so quickly, reflecting body heat, so well. I love the mattress and the side sleeper pillow!
