Hi whispar1,
“Toxic” is a term for poisonous substances produced within living cells or organisms, although the term is often used in the mattress industry (and often part of some “fear-mongering” campaigns), but I think I understand your point. Most people that are looking for “non-toxic” (toxicity is dose-dependent) materials are usually concerned most with “safety”.
As there is quite a bit of confusing information available online about toxicity, safety and organic, there is more about the different types of organic and safety certifications such as Oeko-tex, Eco-Institut, Greenguard Gold, C2C, and CertiPUR-US in post #2 here, and more about some of the differences between organic and safety certifications in post #2 here and there are also some comments in post #42 here that can help you decide whether an organic certification is important to you for environmental, social, or personal reasons, or whether a “safety” certification is enough, and what those certifications can mean to determine whether the contents of any particular mattress are “safe enough” for you.
CertiPUR-US isn’t a guarantee of something being “non-toxic”. You can see what CertiPUR-US certified foams are certified for here. There is also a link on that page to see if a mattress brand or foam fabricator is listed as providing or producing foams that are CertiPUR-US certified. Realize that being on this list only means that the manufacturer or foam pourer produces products that have met this certification – it does not mean that everything they product or sell is necessarily CertiPUR-US certified. You’d need to confirm that with your mattress manufacturer or retailer.
As for all of the mattress models you listed, you need to take the time to refer back to the information I provided in my previous reply to you and find out the information listed here so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase. Having this information will assist you in eliminating products using lower quality and less durable materials.
Specifications on the Love & Sleep Mattress and the Tuft & Needle are listed already in the simplified choice thread here. Nest Bedding is a site member here, which does mean that I think highly of them, their knowledge and their products.
I see you also added in another post that you’re considering the Dreamfoam Arctic Dreams (Dreamfoam is also a site member here). The Arctic Dreams, along with the Love & Sleep, does represent one of the better “value” options on boxed-bed products.
The Nolah, Brentwood Home and Nectar have been discussed previously on the forum and you may use the forum search tool here to search for more information/discussions about them.
Regarding some of the mattresses you are considering, I would also read post #6 here about mattresses imported from Asia or China and which may have been compressed for long periods of time in either shipping or storage before being purchased. Being sourced in China can make these somewhat of a risky purchase IMHO.
What I focus on here in the forum is to assist people with “how” to choose, as it’s not possible to make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort”, firmness, or PPP (Posture and alignment, Pressure relief, and your own Personal preferences) or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress), sleeping positions, health conditions, or “theory at a distance” that can possibly be more reliable than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
If you have more specific questions about the specifications of any of the mattresses you are researching, feel free to post them here and I’ll do my best to comment upon them.

Classic Brands
Unfortunately, there is no meaningful information about the material used in this mattress on the Classic Brands site or Amazon. You can read more about the Dormia / Classic Sleep bankruptcies and their purchase by their supplier and their change into Classic Brands in this article and a more detailed history yet in this article. A forum search on Classic Brands (you can just click the link) will also bring up more comments and feedback about them as well.
Their factory in China currently manufactures mattresses under several different names and makes private label mattresses as well. There are some comments about Chinese mattresses that are shipped compressed from overseas in post #6 here that would be worth reading. I’m not sure if all of the foams, some of the foams, or the entire finished mattress ships from China.
Live and Sleep
Unfortunately, there is little meaningful information listed on their web site or amazon, although on amazon Live and Sleep states the memory foam is 3 lb density (which would be a lower density than I would recommend), and they don’t answer about the density of the polyfoam core. These are manufactured overseas (per their web site), so my concerns about products being compressed for a longer period of time, as I mentioned in post #6 here, would be worth reading. A customer on amazon claims the mattress is made in China, but I’m always cautious about information provided by customers on the amazon site, as there is entirely too much inaccurate information there.
Perfect Cloud
While there are no meaningful specifications listed on the web site or on amazon, in the comments section the memory foam is listed as 3 lb density, which would be below the density I would recommend.
Dura Global is an import and marketing company that imports many types of products and they certainly don’t specialize in mattresses. These mattresses are made in China, and there are some comments about Chinese mattresses that are shipped compressed from overseas in post #6 here that would be worth reading.
Brentwood Home Cyprus
This is listed on the amazon site as using a 6.5" polyfoam base of 2 lb density, a 2" layer of 2 lb polyfoam, and a 2.5" layer of 4 lb memory foam.
Nolah
The Nolah is comprised of:
2" 2.75 lb polyfoam
1" 4 lb Avena polyfoam
7" 1.8 lb polyfoam support core
This product would raise no “red flags” for someone in a more “normal” BMI range, but I would advise a slight caution for someone in a higher BMI range (30+).
Nectar
I’d recommend you read a bit about Nectar on the forum here (just click on the link).
Overall, I would be very cautious about buying any mattress where you can’t find out the specifics of the materials inside it so you can make sure there are no weak links in the mattress and make more meaningful comparisons to other mattresses. Outside of how well a mattress matches your specific needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and your own Personal preferences), a mattress is only as good as the quality of the materials inside it regardless of the name of the manufacturer. If you are able to find out the type and quality of the materials in either of these mattresses and you list them on the forum I’d be happy to make some comments about the quality of the materials.
