Sleeping Organic Mattress Review

Sleeping Organic is a Charleston, South Carolina maker. It sells one fully customizable natural-latex mattress in three builds: the 7-inch Sprout, the 10-inch Leaf and the Tree, with up to four layers. You get GOLS-certified Dunlop options, organic cotton-and-wool covers and split-firmness setups for couples. A 20-year warranty backs it. It's best for chemical-conscious shoppers who want adjustable latex. Its brand site was unavailable when we checked in September 2026, so prices come from an older archived copy.

If you sleep on your side, choose the Leaf or Tree with a soft Talalay comfort layer for shoulder and hip relief. If you sleep on your back, Medium Leaf setups suit average-weight sleepers. The Sprout or firmer Dunlop stacks suit you if you want less sink. If you sleep on your stomach, a firmer Sprout or firm Dunlop-heavy build is the closest fit.

The brand positions the latex plus a wool-and-cotton cover as breathable and moisture-wicking. Wool covers can't be machine washed. Heavier sleepers fit thicker Tree builds with firm Dunlop support layers, but the brand doesn't publish weight guidance (checked September 2026). Couples can split any layer for different firmness per side.

The wool fire barrier meets FR 1633, and the brand claims no chemical retardants. If you have chemical sensitivity, consult a clinician and confirm certifications before you buy.

An archived copy of the brand's site from January 2025 listed Twin builder base prices of $965 for the Sprout, $1,295 for the Leaf and $1,595 for the Tree. Larger sizes cost more. King and California King values reached up to $2,000. GOLS-certified Dunlop upgrades ran from free to $250, depending on the build.

That copy also listed free continental-USA shipping and free shredded-latex pillows with the mattress. The brand doesn't publish current 2026 prices, discounts, financing or checkout totals (checked September 2026). Confirm live prices at checkout.

Comfort layers are 100 percent natural Talalay latex, usually on top for pressure relief, and 100 percent natural Dunlop latex in Soft, Medium, Firm and Extra-Firm. The brand offers GOLS-certified Dunlop. It says GOLS Dunlop is free of harmful chemicals, and that GOLS certification is only available in Dunlop.

The zip-off cover is organic cotton quilted with cotton batting and natural or organic wool for temperature regulation and the fire barrier. Vegan, wool-free covers are made on request. The wool batting meets US law FR 1633, and the brand claims no chemical flame retardants.

The brand doesn't publish layer thicknesses beyond total heights, latex ILDs, densities, wool weights, adhesive details, or GOTS and OEKO-TEX certificate numbers (checked September 2026).

The 20-year warranty runs 10 years of full coverage, then 10 years pro-rated at 10 percent per year. It covers latex cell-structure breakdown showing visible indentation over 1.25 inches not caused by a foundation defect, plus splitting defects. The brand positions latex as resisting premature breakdown for about 20 years.

The zip-off cover lets you rotate, rearrange and replace individual layers. That's a practical way to extend life. The brand doesn't publish independent long-term test data or sag-rate figures (checked September 2026). Use a supportive foundation that meets the slat and frame requirements in the warranty, and add a protector.

The brand's reviews page showed an aggregate rating of 4.6 out of 5 with TrustSpot-verified reviews. Praise covers comfort, pressure relief, no chemical or off-gassing smell, helpful phone guidance and happy couples on split-firmness setups.

Complaints include a heavy build that's hard for one person, or anyone with back issues, to move. Some mention an initial wool cover smell that fades. One pillow-fulfillment issue was resolved by service. We found no Google, Yelp, BBB or Trustpilot counts. Verify current reviews before you buy.

You can buy direct online at sleepingorganic.com. Call 1-800-625-4042 or email cs@sleepingorganic.com. You can also try one at the Charleston-area showroom in South Carolina. The warranty contact address is Sleeping Organic, 804 Meeting St, Charleston, SC 29403.

The brand doesn't publish showroom hours, appointment rules or third-party retailers (checked September 2026). GoodBed lists the brand as a Mount Pleasant, SC maker with the same toll-free number, but with no models or prices.

An archived copy of the brand's site from 2025 promised free shipping anywhere in the continental USA. The mattress is hand-made in the USA and assembled and inspected in East Coast or West Coast warehouses. It ships direct for do-it-yourself assembly. You unbox the layers and insert them into the zip cover.

That copy stated 10 business days standard, with a then-current average of 21 business days. Orders with an assembled foundation or adjustable base ship palletized by freight in about 7 to 10 business days, with a delivery appointment. The brand doesn't publish room-of-choice placement, white-glove setup or old-mattress removal (checked September 2026). Confirm current timelines at checkout.

The 365-Day Comfort Program lets you buy additional layers at a deep discount within 365 days. You can also exchange or rearrange layers.

The brand doesn't publish whether full-mattress returns or refunds are offered, nor return shipping, restocking fees, condition rules, per-swap limits or refund timing (checked September 2026). Confirm written trial, exchange and refund terms before you buy.

The 20-year limited warranty covers the original buyer in the continental USA. It isn't transferable, and resale is as-is. The first 10 years are full coverage. The second 10 years are pro-rated at 10 percent per year.

It covers latex cell-structure deterioration causing visible indentation over 1.25 inches not caused by foundation defects, plus splitting defects. It excludes improper installation, abuse, neglect and misuse. Your foundation must have adequate slats and proper frame legs.

Claims need proof of purchase by phone at 1-800-625-4042, by email at cs@sleepingorganic.com or by mail to 804 Meeting St, Charleston, SC 29403. Confirm the current full exclusions and remedy before you buy.

Against natural-latex specialists like Avocado, PlushBeds, Savvy Rest and Sleep On Latex, Sleeping Organic stands out on per-layer customization and free split layers for couples. You choose Talalay or Dunlop for each layer, and the warranty runs 20 years. The brand claims to be more affordable than other popular latex companies. The brand doesn't publish head-to-head specs or price comparisons (checked September 2026).

Against conventional hybrids and memory foam, latex plus wool targets chemical-conscious shoppers. Mainstream rivals typically offer longer published home trials and white-glove delivery networks.

We read the brand's own product, policy and warranty pages, then checked retailer listings and public complaint sites like the Better Business Bureau. We last checked everything here in September 2026. Prices and policies change, so confirm them on the seller's page before you buy. You can read more in our methodology and editorial policy.
