The Diamond Mattress Sage Organic 1 comes from a family-owned company that has been building mattresses since 1946. It is an organic latex hybrid priced at $2,299, discounted from a listed $2,599, and it carries a 120-night trial plus a 20-year warranty. This page lays out the documented facts so you can decide whether the Sage Organic 1 fits your sleep needs, or whether a different mattress is the smarter buy.
This review is part of our guide to the best organic mattresses, where the strongest models are compared side by side.
Before anything else, here is the short version: buy the Sage Organic 1 if you want organic cotton, wool, and Talalay latex in a coil hybrid, made in the USA, with a 20-year warranty. Look elsewhere if you want a full year to try the mattress at home, or if you want white-glove delivery and old mattress removal included.

Who is the Diamond Sage Organic 1 for?
The Sage Organic 1 is built for shoppers who care about what the mattress is made of. The brand lists unbleached organic cotton with no harmful chemicals or dyes, ethically sourced wool with natural temperature regulating and antimicrobial properties, and Oeko-Tex 100 certified sustainably sourced Talalay latex. If a natural, breathable sleep surface is your priority and you are comfortable with a 120-night trial window, this model is aimed at you.
It is also aimed at people who value domestic manufacturing. Diamond Mattress states the Sage Organic 1 is made in the USA, ships from a US factory, and is backed by a 20-year warranty that the company describes as twice the industry standard. The medium firmness option is the only firmness listed for this model, so it targets sleepers who want a single, balanced feel rather than a menu of choices.
Who should not buy it: shoppers who need more than 120 nights to adjust, people who want in-room delivery and removal of their old mattress, and buyers who insist on multiple firmness options. Those gaps are covered further down this page.
What does the Sage Organic 1 actually contain?
According to the official specifications, the Sage Organic 1 layers organic cotton, wool, and Talalay latex over an individually wrapped coil system. The brand describes these materials as breathable and comfortable layers with naturally antimicrobial and temperature regulating properties. All foams are CertiPUR-US certified, and the mattress holds GREENGUARD Gold certification for low chemical emissions.

The coil system is described by the brand as providing edge to edge support across the mattress and reducing motion transfer for a still and restful night. The cover is a breathable quilted organic cotton that the brand says promotes airflow for a cooler night. The foam is described as high-density, long-lasting, and CertiPUR-US certified.
How does the Sage Organic 1 feel and support you?
The Sage Organic 1 is offered in a single firmness: medium. That means there is no Plush or Firm version of this model to choose between, so your decision rests on whether a medium feel suits your sleep position. The brand does not publish a numerical firmness rating or a sleeper-weight range for this model, so check the official product page for any updated guidance before ordering.
Support comes from the Sage Organic Dynamic Edge Coil System, which uses individually wrapped coils. The brand states these coils provide support that adjusts with you, edge to edge support, and reduced motion transfer. Above the coils, the Talalay latex and wool layers provide the comfort and pressure relief portion of the feel. The latex is Oeko-Tex 100 certified and sustainably sourced, and the wool is ethically sourced with natural temperature regulating and antimicrobial properties.
Because the medium feel is the only documented option, combination sleepers who rotate between positions should confirm on the official page whether the medium works for stomach sleeping, which typically needs a firmer surface. Lighter sleepers often find medium mattresses too firm, and heavier sleepers often want more support than a single medium can give. Those are general buying principles, not claims about this specific model.
Does the Sage Organic 1 sleep cool?
Cooling is a common question, and the documented facts show the Sage Organic 1 relies on breathable materials rather than any branded cooling technology. The brand lists breathable quilted organic cotton that promotes airflow, naturally temperature regulating wool, and breathable Talalay latex. The coil layer also allows air to move through the mattress.
If you sleep hot, check the official product page for any updated temperature claims and read recent verified reviews for real-world reports. Who this matters for: hot sleepers, people in warm climates, and anyone who shares a bed with a partner who runs warm. The materials list is promising on paper, but the brand does not publish a cooling performance rating for this model.
How is motion transfer and edge support on the Sage Organic 1?
The brand states the individually wrapped coils reduce motion transfer for a still and restful night, and that the coil system delivers edge to edge support across the mattress. Those are the only documented claims about motion and edges for this model. The brand does not publish test scores or numerical ratings for either.
Who this matters for: couples, where one partner gets in and out of bed at night, and anyone who sits on the edge of the bed to put on shoes or get up in the morning. Check the official page and recent customer reviews for current reports on how the edges hold up over time.
What does the Sage Organic 1 cost, and what do the policies cover?
The Sage Organic 1 is listed at $2,299, marked down from $2,599, for a stated savings of $300. The price is shown as a regular price for the model, and the brand notes that the Manufacturer’s Suggested Retail Price shown as a crossed-out reference price may not represent actual or future prices. Check the current price on the official site before you buy, as pricing can change with promotions.
The trial is 120 nights, starting from the day the mattress arrives. The brand recommends trying it for at least 30 nights to allow your body to adjust, and states that returns or exchanges are easy within the 120-night window. Trial terms are linked from the product page. The warranty is 20 years, which the brand describes as twice the industry standard. Shipping is free, and the mattress ships in 3 to 5 business days via FedEx.

Who should buy the Sage Organic 1, and who should not?
Buy the Diamond Mattress Sage Organic 1 if organic and certified materials are your top priority, if you want a medium feel in a latex and coil hybrid, if you prefer a product made in the USA from a family-owned company with nearly 80 years of experience, and if a 20-year warranty gives you confidence in the purchase. The listed price of $2,299, down from $2,599, positions it in the premium organic tier, and free shipping with a 3 to 5 business day dispatch keeps the buying process simple.
Do not buy the Sage Organic 1 if you need more than 120 nights to decide, since the trial is 120 nights and the brand recommends at least 30 nights of adjustment before judging the feel. Do not buy it if you want in-room delivery and old mattress removal, because the documented shipping method is FedEx to your door. Do not buy it if you want a choice of firmness levels, because medium is the only firmness listed for this model. Do not buy it if you want a lifetime warranty, because the Sage Organic 1 carries a 20-year warranty.
Also skip it if you are on a tight budget. The brand’s own lineup includes lower-priced options, and the Sage Organic 1 sits at $2,299. Check the current price on the official site and compare it against other organic hybrids before committing.
How does the Sage Organic 1 compare to the Saatva Classic?
The Saatva Classic is the natural alternative for shoppers who want a longer trial, full-service delivery, and a lifetime warranty instead of a 20-year one. Both are coil-based mattresses with organic cotton in the cover. The differences that matter most are trial length, delivery service, warranty term, and firmness choice.

Who should buy the Diamond Sage Organic 1: shoppers who prioritize organic cotton, wool, and Talalay latex by name, who are comfortable with a 120-night trial and FedEx delivery, and who want a single medium feel backed by a 20-year warranty from a family-owned US manufacturer.
Who should buy the Saatva Classic: shoppers who want a full year to try the mattress, free in-room delivery with setup and old mattress removal, a lifetime warranty, and a choice of three firmness levels and two mattress heights, including a design focused on lumbar support.
Verdict
The Diamond Sage Organic 1 earns its place for organic-material shoppers who are fine with a 120-night trial and FedEx delivery. If you want a 365-night trial, white-glove setup with old mattress removal, three firmness choices, and a lifetime warranty, the Saatva Classic is the stronger buy. Check the current price on the official site for both before ordering.
World Sleep Almanac score: 7.3/10
The World Sleep Almanac editorial score is our own rating, written from the documented facts on this page and scored against five criteria. It is not a lab test and not a hands-on evaluation. The criteria and how the Sage Organic 1 scores on each:
- Materials and construction: 9/10. Named organic cotton, ethically sourced wool, Oeko-Tex 100 Talalay latex, GREENGUARD Gold and CertiPUR-US certifications, made in the USA.
- Warranty: 7/10. A 20-year term that the brand calls twice the industry standard, though it is shorter than a lifetime warranty.
- Trial and returns: 6/10. 120 nights with a recommended 30-night adjustment period, which is shorter than the 365-night trials common at premium rivals.
- Price at equivalent size: 7/10. $2,299 marked down from $2,599 is competitive for a named organic latex hybrid, but check the current price on the official site.
- Public customer reviews: not scored. The dossier does not include a published review count or rating for this model, so this criterion is excluded from the average rather than guessed.
The score reflects strong documented materials and certifications held back by a shorter trial and a 20-year rather than lifetime warranty. If a future update changes the trial length, warranty term, or certification list, the score will be revisited and the reason stated here.
