The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.

Our editors have researched and slept on dozens of soft, organic mattresses — these are our top selections for side sleepers or anyone looking for extra cushion.

Side sleepers, rejoice, for it’s finally your time to shine. 🪩💤

While stomach and back sleepers normally opt for firmer mattresses, side sleepers (this editor included) can benefit from softer mattresses. The same goes for those with joint pain in the shoulder, hips, or back, or lightweight individuals — mattresses that contour to your shape and provide relief are invaluable for good sleep. With that in mind, you’ll want a soft mattress that offers spinal alignment, cushioned top layers to alleviate pressure points, and any sort of memory foam, innerspring, or hybrid combo. 

Why choose an organic mattress?

Many conventional mattresses are made with polyurethane foam (a petroleum-based material), chemical flame retardants, and other additives that can release volatile organic compounds (VOCs) into the air over time. Considering we spend nearly a third of our lives in bed, regular exposure or inhalation of these compounds can raise concerns for both health and indoor air quality.

That’s why choosing an organic mattress can make such a difference. Certified organic materials — like natural latex, organic cotton, and wool — are nontoxic, biodegradable, and sustainably sourced. They’re crafted without harmful glues or synthetic dyes, offering a cleaner, healthier sleep environment.

Beyond being better for you, organic mattresses are also kinder to the planet. The natural materials are responsibly harvested, often renewable, and processed using eco-friendly methods that reduce waste and chemical runoff. Plus, because these materials are inherently durable and resilient, organic mattresses often outlast their synthetic counterparts, maintaining comfort and structure for years to come.

How to choose the right firmness (or softness) for your sleeping style:

When choosing the right firmness for your sleeping style, think about how your body naturally rests and where you need the most support. Most experts agree that medium-firm mattresses promote the best comfort and sleep quality — so if you prefer a soft mattress, materials can make all the difference in how comfy your mattress feels to you.

If you’re a side sleeper, a softer mattress made with materials like organic latex, organic cotton, or nontoxic memory foams can gently cradle your shoulders and hips, relieving pressure while keeping your spine aligned. Back sleepers generally do best with a medium-firm mattress that combines comfort and stability — think natural latex or hybrid designs with a supportive coil base and a slightly softer top layer. This setup helps maintain proper lumbar support without feeling rigid. For stomach sleepers, a firmer mattress crafted from dense organic latex or innerspring coils is ideal to keep the hips from dipping too low, which can strain the lower back. These materials are naturally resilient, offering the lift and structure that stomach sleepers need.

What is our review process?

Eight out of these nine mattress brands on this list has been personally reviewed by one of our editors. Unlike other review sites, we bring these mattresses into our homes and sleep on them for months (sometimes years!) to see how they hold up and feel over time. Our top considerations are health and safety, comfort, environmental impact, durability, and long-term value. In addition to hands-on testing, we tour factories, investigate certifications, interview brands, scour online reviews, and survey our own readers for your preferences. We’ve got your back when it comes to finding the softest nontoxic mattresses for your home!

Our criteria:

We’ve found nine of the softest mattresses on the market from organic and sustainable brands. Our editors have personally tested these products, spoken to the brands, and/or scoured online reviews to select the absolute best, and this guide is updated regularly with new favorites. Plus, all of these brands also offer generous warranties, financing plans, and customer service support to ensure you’re happy with your new super soft purchase.

  • SOFTNESS | Most bedding companies use a scale of 1 to 10, 1 being the softest. We’d consider anything under a 4.5 to be on the softer side, with most of the options below ranging from 2–3.
  • ORGANIC | Each of these brands uses organic, sustainable, and nontoxic materials, including organic cotton, organic wool, plant-based BioFoam, and natural latex. Any additional organic certifications are mentioned alongside the brand below.

If a new mattress is out of the budget — or your current mattress still has a lot of life left — but you’re hoping for a softer experience, consider our list of the best organic mattress toppers. And if you are in the market for a new mattress but have particular preferences, our guides to the best natural latex mattresses, fiberglass free mattresses, cooling mattresses, and our top organic mattresses can steer you in the right direction.

Our Editor’s Review | “I laid down on my new bare mattress and immediately noticed that well, there was nothing to notice — no smell, no stiffness. Lying on my new mattress, I had the sense of being gently held while also supported, kind of like how it feels when someone puts a comforting hand on your lower back — reassurance without pressure.” – Trinity Wilbourn, Contributing Editor at The Good Trade [Read the full review.]

Avocado’s Organic Mattress in Ultra Plush may actually redefine luxury. With a whopping 17 (!) premium layers and thousands of individually encased coils, this mattress is about as top-of-the-line as you can get. Here’s how it breaks down: The Ultra Plush model comes in at 19” high, including multiple layers of organic latex, cotton, wool, and alpaca fibers, plus a 3” box top comfort layer. That translates to an impressive seven ergonomic zones for support — so side sleepers seeking relief in their hips and shoulders will easily find it. Plus, it’s loved by our editors — for more deets, check out our in-depth review.

With the most eco-friendly certifications we’ve ever seen on one mattress, Avocado’s commitment to minimizing its footprint and maximizing sustainability is unparalleled.

In-home delivery is required starting at $249, but thanks to the impressive warranty, customer service, and 0% financing, we think this one is worth the investment if you’re looking for luxury.

Our Editor’s Review | “First things first, I needed to test the plushness. Being a regular human and not a mattress expert, I did what seemed right: I felt for the Goldilocks balance of just enough cushiness that I would sleep like a baby, without so much cushiness that I would, like a baby, not be able to get out of bed by myself.” – Trinity Wilbourn, Contributing Editor at The Good Trade [Read the full review.]

Our Editor’s Review | My first night sleeping on the Oceano was truly unlike any night of sleep I’ve ever experienced. The Oceano is medium soft, rated a 4.5/10, but with reinforcement from springs and edge protection. It was so comfortable. I woke up twice throughout the night, once to turn off the AC unit and another to use the bathroom. I’ve never been so happy to wake up in the night.” – Ashley D’Arcy, Senior Editor at The Good Trade [Read the full review.]

Our Editor’s Review | “This mattress is luxe, in all the best and most rewarding ways. For instance, I had been worried that the Euro top would be too squishy as we have not been a fan of the bed we slept on with a pillow top. My worries were unfounded as the Birch Luxe Euro top was just enough to gently hug all the right spots without making you feel like you’re sinking into the mattress. ” – Randi Donahue, Contributing Editor at The Good Trade [Read the full review.]

Side sleepers who run hot will want to pick up the Bear Elite Hybrid Mattress in Soft. This hybrid mattress leverages copper-infused memory foam, zoned coil system, and thermoregulating fibers to keep you calm and cool all night long — while simultaneously offering relief to your joints. It’s so cool to the touch, you can say goodbye forever to tossing, turning, and waking up sweaty. Bear has been named a top mattress by numerous publications — and we certainly agree. This award-winning bed is made in Arizona and ships to you for absolutely free. (Returns are free, too — but we sense you may not need that!) Bear also provides a lifetime warranty and 120-night trial to ensure you enjoy this mattress for the long-term. Breathable, sustainable, and durable. Ahh. (That’s a sigh of relief.)

Our Editor’s Review | “Is the Bear Elite Mattress comfortable? In short — ask the drool stains on my pillow. But the longer answer here is that the Bear Elite is certainly firmer than previous mattresses I’ve owned, but the cushy top offers softness without sacrificing stability. I’ve noticed that I stay asleep more consistently throughout the night, and even stopped waking up anxious before my alarm.” – Emily McGowan, Editorial Director at The Good Trade [Read the full review.]

I sleep on both my side and my stomach throughout the night, and I’m happy to report that the mattress felt comfortable in any position — firm, but not too firm for side sleeping.” – Paula K.
