Description

Experience The Comfort of Pure Green Natural Latex Foam! The Medium Firmness Topper adds pinpointed support to the mattress without changing the overall firmness level of the mattress. While this topper is most popular with back sleepers, it can be the perfect compromise for couples with different preferences. It can also be great for rejuvenating a firm mattress with a worn-out comfort layer. Many use our medium toppers in DIY mattress projects. We also offer Soft and Firm firmness versions of this topper. Natural Latex Foam is a comfortable, durable and breathable material that is the perfect addition to the top of any mattress. We designed the Pure Green Natural Latex Mattress Topper to capture and enhance the best qualities of natural latex foam. It is made with the purest formulation possible through a superior production process and is certified under internationally recognized health and environmental standards. In 2013 we introduced The Pure Green Natural Latex Foam Mattress Topper. We made the topper with natural latex (harvested from rubber trees), no synthetic latex (latex made from petrochemicals) and manufactured it to the highest aesthetic and performance standards. Over the years, we obtained several certifications to ensure and verify the safety of the topper. In 2019, we began sourcing our natural latex exclusively from certified organic rubber trees and became GOLS certified (Global Organic Latex Standard). The GOLS certification signifies our commitment to Organic agriculture and is a step towards a more sustainable supply chain. In 2021, we became Fair for Life Fair-Trade certified and established a network of fair-trade certified small farmers in Sri Lanka who we source latex from. The Fair for Life Certification ensures that all stakeholders are treated fairly and the communities that provide us with latex are supported. ‏‏‎ ‎ Comfort and Support - Natural Latex Foam reacts instantly to provide perfect comfort and support. Unlike memory foam, you'll never experience any sinking as the night goes by. Our topper will maintain contoured support throughout the night. Durability - Natural Latex Foam is more durable than most types of polyurethane foam or memory foam. Our mattress topper will probably last longer than the mattress you use it on top of. Breathability - Natural Latex Foam is heat neutral. It will not absorb body heat or change firmness depending on the temperature. Latex foam is an open-celled foam and contains tiny air chambers that run throughout the foam. These air chambers allow the air to flow freely through the topper. While a latex foam topper can not always make a bed cooler, a 2"-3" topper can serve as a great buffer between your body and a hot memory foam (or polyurethane foam) mattress. We produce our foam with natural latex harvested from organically grown rubber trees; we never use any synthetic latex in our foam. We also never use any fillers. The use of fillers lowers the cost to produce latex foam but comprises the foam's performance qualities. It is challenging to maintain cosmetic and performance consistency when manufacturing natural latex foam. Unlike synthetic materials, which always have the exact same composition, the composition of natural latex harvested from rubber trees continually changes slightly with the weather and seasons. Our manufacturing team works hard to continually adjust to the latex to provide the highest consistency possible. We make our foam in moulds through an enhanced version of the Dunlop Process, which results in foam that is springy but not "bouncy" like latex foam made through the Talalay process. We only advertise certifications issued directly to our company (Sleep On Latex). Anyone can independently verify these certifications through the certification bodies that administer the certifications. We undergo auditing and testing, which allows the certifying bodies to continually monitor our compliance. Each topper box we sell contains a GOLS label with a tracking number that allows us to trace the latex back to the field. Our 1" toppers are great for adding a subtle change to the surface of a mattress without adding much additional height. While it will not provide a drastic change a 1" topper can be used to tweak surface feel of the mattress. Our 2" toppers are the most popular topper height we sell. They are great for adding a significant change to the surface of the mattress while still retaining the general support of the mattress underneath. Our 3" toppers will provide a "mattress makeover". They dominate the feel of the mattress to revitalize and reinvigorate an old mattress. They can also be used to create large changes in the firmness of a mattress.

  • Works great! No Smell!
Size: California King Style: 1" Topper
I purchased a new mattress that turned out to be completely too hard. Bought a 2" foam topper. That topper only lasted under 2 yrs. I have terrible allergies and breathing problems. Did some research and turns out foam is the worst thing for it. So went searching and found natural latex is much better and no major off gassing. After searching for days for a 1" natural latex topper for california king bed I found this topper. Ordered it and it was delivered fairly quick. We opened it and spread it out. There was only a very slight smell. We left it for 24 hours then put it on the bed. It is easy to handle and move around. It has a few blemishes in it but nothing drastic. It made a difference immediately for both me and my hubby. The 1" gives just enough cushion without making the bed too soft. It's like anything else took a couple days to get used to it and now it's great. I never noticed any smell at all after putting it on the bed. I always use a mattress pad and sheets on top of the topper. With the foam I still noticed a chemical smell. With this natural latex topper I have not smelled anything since putting it on the bed. I recommend this product if you're looking for something better than foam. ... show more

  • Love these toppers
Size: Full Style: 1" Topper
I have a new Zinus memory foam bed. I like it, but found it hard to move around as I sank into the foam through the night and woke up with a stiff back which aggravated my lower back problems more through the day. I bought a 2" firm topper first, and it really helped at first. After a few nights, I found it to be a little too firm and my back was stiff again. I read a lot of the reviews that combined toppers, so I ordered the 1" medium to go on top the first, and I love It! Together they are soft enough that I can sink into a little plush feeling, but still firm to hold my spine in a line. I can move around and not sink into the mattress. No back pain in the morning. I also switched to a thinner pillow since my spine is now aligned correctly. There was a latex smell the first month, but it was not overpowering and I don't smell it anymore. Together these two toppers cost more than the bed, but they are well worth the money for a good nights sleep. I am a small person, but I think these would work well for anyone. They are very well made and true to size. ... show more

  • Terrific
Size: Twin XL Style: 1" Topper
I'm very well read on mattresses and understand how challenging it can be for people to find a good mattress. I have had standard innersprings, high end pocket coils, memory foam and more. Many may want to consider a modular approach. I have a 7" thick throwback mattress with standard innersprings, horsehair, and cotton - no polyester to deform. Had it for >15y - nothing affects it's shape, and it is flippable (highly recommended). That allows me to trade out and experiment with what sits on top of the mattress. That said, I have no need to experiment - latex toppers are much cooler than memory foam, they instantly spring back so there's never a hole you're in, and best of all, they conform to your body better than memory foam by far, and no worse than the best pocket coil system. And they allow customization, I have this 1" on top of a denser weight 2" latex topper. ... show more

  • Initial review and secondary review
Size: Twin Style: 1" Topper
This is my initial review. I bought the 2" medium king size, the initial quality appears to be good, there were some slight imperfections but nothing significant. Unpacking was a breeze, there is a definite odor. The density feels more like soft than medium and the topper seems delicate when removing plastic cover. This topper is heavy and doesn't have a cheap, flimsy feeling. The fitment is slightly large and has some over hang (all four sides) on our brand new firm mattress. I will review in the future to give more detail about comfort and my overall experience with this topper. I will add the delivery was very fast and without any damage. ** 8/10/16 SECONDARY REVIEW**- User's weight 130 lbs. and 150 lbs. I will preface this portion of my review with the fact that I have T and L spine problems. It only took me one night to determine this topper was not for me. This topper is supposed to be a medium firm but it really is more like a soft density. It did not provide adequate support for me or my partner, we both could not sleep through the night due to pain. These densities are really basic descriptions and each person's interpretations and opinions are different. This topper is soft and best suited for people who want a soft, non supportive topper. I do not recommend this topper to individuals who either want or need good support while sleeping. I started the process for a return. In fairness, this company "Sleep on Latex" has excellent customer service and the two people I spoke with about my issues were very helpful and professional. ... show more

  • I recommend it.
Size: Queen Style: 1" Topper
I bought it in 2018 and am currently using it until 2026, but I'm thinking of just changing the cover. Although the price has increased quite a bit, I think it was a valuable choice.

  • Not good for hot sleepers
Size: Queen Style: 1" Topper
The medium firm is more medium soft. Since it is soft, it encompasses the body and causes heat. I would not recommend this for back sleepers who sleep hot.

  • Great relief for a small 1 inch topper
Size: Queen Style: 1" Topper
This is the second topper that I bought within a very short period of time. I only have the ability to work with a 1 inch topper due to the limits of our fitted sheets. The first was a memory foam - and although it was incredibly comfortable, it was also incredibly hot. I tend to sleep cold, so for me to be hot says it all. The memory foam topper is sitting up in the attic and we don't know what to do with it. It'll be too hot to even make a dog bed out of it. So I purchased this latex topper with holes in it and it's terrific. It is soft and comfortable without being too cushy. It helps with my sore hip and shoulder. It breathes so there is no overheating. It has a cover you can purchase with it although in hindsight I don't know if it was necessary if you already have a good bed pad that you use under your sheets. Overall I'd endorse this latex mattress topper. ... show more

  • Expensive & doesn't last
Size: Twin Style: 1" Topper
I purchased this topper 11/2023; after 1 year, I've replaced it with a 2"gel-foam topper. The Pure-Green Natural latex was "OK" for about 8mo's, then it began to sag forming a low depression in the area of my lower back, leaving me with lower back issues, as soon as I awoke. At the time I thought buying a more expensive topper, equaled longer lasting value; my back discomfort says I was WRONG making this assumption. ... show more
