The 5 Softest Mattresses From Organic Brands (2023)

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

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. 

But bear in mind, many mattresses out there are made with polyurethane (derived from oil), chemical fire retardants, and hazardous VOCs (volatile organic compounds). Considering we spend a third of our lives in bed, the risk of exposure and/or inhalation of these compounds runs high. That’s why we’re focused on the best organic mattress — the materials are nontoxic, they’re more sustainable, and they often last longer than synthetics. 

We’ve found five 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.

Our criteria:

  • 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.
