The Spindle Latex mattress is a 10-inch all-latex bed built from three 3-inch layers of organic Dunlop latex, wrapped in a quilted cover of organic cotton and wool. The core idea behind the design is adjustability: the layers ship in soft, medium, and firm, and you can rearrange them to change the feel of the surface. Shoppers who want an organic latex mattress with a documented, adjustable firmness range and published layer specifications will find a concrete reason to consider it.

What is the Spindle Latex mattress made of?
The Spindle Latex mattress contains 9 inches of organic Dunlop latex split into three 3-inch layers, plus a 1-inch quilted cover made of organic cotton and wool. The latex is manufactured in Sri Lanka, and the raw material source is also listed as Sri Lanka. The cover fabric is a circular knit organic cotton at 360 gsm, knitted in Canada from raw material sourced in the USA and India. The wool batting is listed at 1.8 pounds per yard and carded in California. The brand states the mattress is designed, quilted, sewn, assembled, and packaged in the USA.
The certification list on the official page includes GOTS certified organic cotton, plus Oeko-Tex Standard 100 and GOLS certified organic latex. The mattress type is listed as all latex, and the firmness is described as interchangeable from medium, rated 5, to firm, rated 7.5 on the brand’s own scale. Shoppers who care about what touches their skin at night will find the cotton, wool, and latex each accounted for, with a stated origin for every component.
How does the adjustable layer design work?
The mattress ships with one soft layer, one medium layer, and one firm layer, and the brand states you can position the layers in any order you like. If you sink too far, you rearrange the layers until the support feels right. The layer densities and indentation load deflection values are published on the official page: 3-inch soft layer: 20 to 23 ILD, 65 kg per cubic meter; 3-inch medium layer: 26 to 29 ILD, 75 kg per cubic meter; 3-inch firm layer: 34 to 37 ILD, 85 kg per cubic meter. The brand notes that firmness is subjective and depends on height, weight, body shape, and sleep position, so everyone experiences a different feel on the same mattress. The scale itself is described by the brand as unscientific and based on the opinions of Spindle and its customers.
Most mattresses ask you to commit to a feel before you have slept a single night on them, and a wrong guess means living with it or paying to send it back. Spindle’s approach treats firmness as something you tune over time. The three layers can be stacked in different orders, and the brand describes roughly three distinct feels available from the same set of materials. If the mattress ends up too soft or too firm after a few weeks of use, the fix is moving layers around rather than starting a return.
ILD measures how much force it takes to compress the foam, and the spread from 20 to 37 across the three layers is wide enough to produce a meaningful difference between configurations. The density figures climb alongside the ILD numbers, which is what you would expect: firmer latex is denser latex. Publishing these numbers is a level of transparency that many mattress brands skip entirely.
What does the Spindle Latex cost?
The official product page lists a price range of $1,199.99 to $1,999.99, with a crossed-out range of $1,749.99 to $2,599.99 shown alongside it. The available sizes are Twin (38 by 75 inches), Twin XL (38 by 80 inches), Full (53 by 75 inches), Queen (60 by 80 inches), King (76 by 80 inches), and California King (72 by 84 inches).

How does the Spindle Latex feel and support the body?
According to the official specifications, the latex has an open cell structure and the brand states that this, combined with wool, provides a cooler sleep surface than most mattresses. The brand also states that latex contours to the body gently and immediately bounces back into place when you move or shift your weight. The brand positions the mattress as having a traditional springiness that removes any sensation of being stuck, which it describes as the benefit of latex foam: a healthy bounce. The 10-inch model is described as having a balanced firmness of comfort and support, sitting between the softest option around 5 and the firmest closer to 7.5 on the brand’s scale.
What about cooling, motion isolation, and edge support?
The official page addresses cooling directly: latex’s open cell structure combined with wool is stated to provide a cooler sleep surface than most mattresses. That is the only cooling claim documented for this model. If these factors matter to your household, the 120-night trial gives you a window to evaluate the mattress in your own bedroom. Couples in particular should pay attention to motion transfer, since a latex bed with a healthy bounce behaves differently from foam in that respect, and the trial is the honest way to find out how it works in practice.
What are the trial, warranty, and comfort program terms?
The Spindle Latex comes with a 120 night risk free trial, a 10 year limited warranty, and a 25 year Comfort Life program. The brand describes the Comfort Life program this way: at any time during your ownership, you can exercise the option to modify the mattress by buying another layer of latex at a 30% discount from the then current prices. The brand frames this as a response to pro-rated warranties that cost money to settle a claim. Free shipping is listed on the product page, with an asterisk that the official page does not expand in the captured content.
The option to buy a replacement layer at a 30% discount for 25 years turns the mattress into a maintainable object rather than a disposable one. Over that span, replacing a single 3-inch layer costs far less than replacing an entire mattress, and the program keeps the rest of the construction in service. The 120-night trial is shorter than the 365 nights some competing brands offer, so it rewards shoppers who are ready to decide. Buyers who like long evaluation windows should factor that difference into the decision.
Who should buy the Spindle Latex?
The Spindle Latex suits shoppers who want an organic latex mattress with a documented, adjustable firmness range and published layer specifications. It fits buyers who value a 120-night risk free trial and a 25 year Comfort Life program that lets them buy replacement latex layers at a 30% discount. It also fits people who prefer a healthy bounce and a surface that bounces back immediately when they shift weight, per the brand’s own description. Finally, it suits shoppers who want GOTS certified organic cotton and GOLS and Oeko-Tex Standard 100 certified latex in the materials list. If you fall into one of these groups, the adjustable three-layer design gives you a concrete way to change the feel without replacing the whole mattress. Rearranging layers is a slower fix than a return, but it is a fix you keep rather than a transaction you undo. For all three, the Spindle design offers something most mattresses do not: a way to change your mind after the purchase.
Who should NOT buy the Spindle Latex?
Skip this mattress if you need a firmness choice that is fixed at checkout rather than adjusted by rearranging layers, since the Spindle design requires you to move the layers yourself. It is also a poor fit if you want a coil or innerspring construction, because the official specs list this as an all latex mattress with no coils. Shoppers who rely on published motion isolation, edge support, or durability test data will not find those figures on the official page, so check the current product page for any updated data before deciding. If you want a lifetime warranty instead of a 10 year limited warranty, this model does not offer one.
How does the Spindle Latex compare with the Saatva Classic?
The Saatva Classic is an innerspring mattress with a dual-coil design made of triple-tempered recycled carbon steel, a 3-inch Euro pillow top, and three comfort levels: Plush Soft at 3/10, Luxury Firm at 5-7/10, and Firm at 8/10. It comes in two heights, 11.5 inches and 14.5 inches, and carries a 365-night home trial with a lifetime warranty. Free white-glove delivery includes in-room setup and old mattress removal. Where the Spindle Latex makes you rearrange layers to change feel, the Saatva Classic lets you choose the comfort level before the mattress arrives. The Saatva Classic also carries CertiPUR-US certified foams, GREENGUARD Gold certification, and endorsement from the American Chiropractic Association.
Verdict
The Spindle Latex earns its place for shoppers who want organic Dunlop latex, published ILD and density figures, and a firmness they can tune by rearranging three 3-inch layers instead of returning the mattress. The 120-night trial and 10 year limited warranty are shorter than some rivals offer, but the 25 year Comfort Life program with replacement layers at a 30% discount keeps the bed serviceable for decades. Buyers who want a coil construction, a fixed comfort level at checkout, or a lifetime warranty should look at the Saatva Classic instead.
World Sleep Almanac score: 7.8/10
Price at equal size: 8/10, the $1,199.99 to $1,999.99 range sits below many organic latex rivals. Trial and returns: 7/10, the 120-night window is shorter than the 365 nights some brands allow. Warranty: 7/10, a 10 year limited warranty is solid but not lifetime, though the 25 year Comfort Life program softens that. Materials and construction: 9/10, GOTS cotton, GOLS and Oeko-Tex certified latex, published ILD and density figures, and stated origins for every component.

Frequently asked questions
Can I change the firmness after the mattress arrives?
Yes. The three 3-inch layers ship as one soft, one medium, and one firm, and the brand states you can position them in any order you like. If the surface feels too soft or too firm, you rearrange the layers until the support feels right. The brand describes roughly three distinct feels available from the same set of materials.
What ILD and density does each layer have?
The 3-inch soft layer is 20 to 23 ILD at 65 kg per cubic meter, the 3-inch medium layer is 26 to 29 ILD at 75 kg per cubic meter, and the 3-inch firm layer is 34 to 37 ILD at 85 kg per cubic meter. The spread from 20 to 37 ILD is wide enough to produce a meaningful difference between configurations, and the density figures climb alongside the ILD numbers.
Where is the latex sourced and manufactured?
The official page lists the organic Dunlop latex as manufactured in Sri Lanka, with the raw material source also listed as Sri Lanka. The cover fabric is a circular knit organic cotton at 360 gsm, knitted in Canada from raw material sourced in the USA and India. The wool batting is carded in California, and the mattress is designed, quilted, sewn, assembled, and packaged in the USA.
What certifications does the Spindle Latex carry?

What sizes are available?
The available sizes are Twin (38 by 75 inches), Twin XL (38 by 80 inches), Full (53 by 75 inches), Queen (60 by 80 inches), King (76 by 80 inches), and California King (72 by 84 inches). The official product page lists a price range of $1,199.99 to $1,999.99, with a crossed-out range of $1,749.99 to $2,599.99 shown alongside it.
How does the 25 year Comfort Life program work?
At any time during your ownership of the Organic Latex Mattress, you can exercise the option to modify the mattress by buying another layer of latex at a 30% discount from the then current prices. The brand frames this as a response to pro-rated warranties that cost money to settle a claim. Replacing a single 3-inch layer costs far less than replacing an entire mattress, and the program keeps the rest of the construction in service.
Is the cooling claim measured?
The official page states that latex’s open cell structure combined with wool provides a cooler sleep surface than most mattresses. No test figures accompany that claim, so shoppers should weigh it as a brand statement rather than a measured result. The 120-night trial gives you a window to evaluate the mattress in your own bedroom.
