Description

Experience The Comfort of Pure Green Natural Latex Foam! The Firm Topper is extremely strong and supportive without being rigid or stiff and is best for those who prefer to sleep on a firm mattress. While it is always tricky to add firmness to a mattress that is too soft, we do have customers who do this successfully using at least a 2” or, preferably, 3” firm topper. It can also work great as a bottom layer in a DIY mattress. We also offer Soft and Medium 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 (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 one of the most durable bedding materials on the planet. It is far 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 using 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.

  • Bounces Back but Relieves Pressure Points!
Size: King Style: 1" Topper
This review is based off of our first night. May update review after time. But wow! Oh wow! We have used high density Viscose memory foam toppers for years. Always found relief from pain. But after a couple years, even with a 4" name brand topper, we would sink. My elderly grandparents slept in our bed for an overnight visit and called our bed quick sand. We knew we needed a new topper. Our matters is still in great shape with little to no 'dents'. But $200+ for ANOTHER memory foam topper? Not ideal. So latex was the choice this time. I did tons of research. Even considered buying a 10" mattress out of the box that is a blend of latex, Energex and memory foam. But decided to try this topper before sinking a grand. Glad we did! Immediately we are impressed. The 1" topper in firm does wonders on a firm bed. It relives pressure but bounces back. You don't sink. We have a 2" memory foam topper on top of the firm latex topper and it is like sleeping bliss. Better than I'd imagine clouds would feel. I think my aching joints will thank me after a week of sleeping on this new set up. I highly recommend this topper! Bottom line: If you want support that relieves pressure, try natural latex. It is cooler than memory foam but also seems to support under a thin memory foam topper. Depends on your needs really. It would suffice alone if a person preferred a firmer surface. But my body needs a little softer. So we added a thin high density memory foam topper. Awesome combo! Much better than memory foam alone! And the initial odor is weird, but it isn't overwhelming and after putting a mattress pad and sheets over it, we don't notice it at all. This is straight out of the box too. Give it a try! Update Almost 1 year later... Our previous mattress completely failed after our most recent move. We suspect some individual coils had seen enough movement (coil mattresses really don't like being moved) and simply collapsed when being transported in the moving truck. We ended up buying an extra firm, maximum coil, double sided mattress with a 20 year warranty. Crazy right? Well, we added the same toppers to our new mattress to hopefully prolong the life of the set and bring some relief to aching joints. While we don't need this topper to enhance the firmness of our new bed, we are using it to help extend the mattress life. We still have the 2" memory foam topper on top of the latex topper for extra softness and pressure relief. As far as this topper goes, it still looks and feels brand new. If we ever decided to stop using it on our king bed, we would cut it in half to use on our kids twin beds. It really does seem it will hold up for years to come. Thanks for making a great natural, quality bedding product! ... show more

  • Comfy and caused me no lower back pain
Size: Twin XL Style: 1" Topper
I had previously bought a 2" medium firmness mattress topper. It was a quality mattress topper; it was dense, soft, and unbelievably comfortable. Unfortunately, it was way too soft and caused me lower back pain from the first night. Although it was extremely comfortable and I slept soundly, I woke up with a not insubstantial pain. I know they say sometimes your body has to get used to it, but after enduring it for 3 days I decided it wasn't worth it and returned it. The return process was easy and I got my refund promptly. Because of how comfortable it was, I decided to give them another shot and bought the 1" firm mattress topper. This was just as comfortable but it was firm enough that it has caused my lower back absolutely no pain. It also smells less than the 2" medium mattress topper. Not that it smelled bad, but it had a pretty strong green tea-like aroma, which I happened to enjoy. The 1" one smells vaguely the same at first but the smell has since dissipated completely and I smell nothing. For reference, I sleep on a mattress that most would probably rate a 9/10 in firmness; I wanted to get a topper to soften my mattress up a tiny bit. ... show more

  • Is quslity firm topper.
Size: Queen Style: 1" Topper
I bought a new firm matress. I like it for my back. But...it was a little to ungiving. I didn't want a thick topper where I would sink in. I tried this thinner one though pricy. I'm happy with it over all. It is a firm topper. I just wanted a little give when laying on it. If your looking for a soft sink in topper this wouldn't be the one. If you want to maintain the firmness of your matress with a little give for your bones, this may work. It rolled out on the bed nicely. It is thin, yet dense and a little firm. I did not notice a smell but was advertised as good quality. Basically, happy with my purchase. ... show more

  • Perfect for Stomach/side sleepers. Perfect firmness. Don’t shy away because of the smell comments.
Size: King Style: 1" Topper
We bought a new Dreamcloud hybrid mattress for $1000+. It was too soft for me. My girl loves it as-is. She’s a side/back sleeper. So, I needed some sort of compromise. I believe the mattress firmness is a 7. I tried a new bed frame for firmness but that didn’t help. If I slept on my side it was fine but I tend to roll onto my stomach A LOT and that would cause me to wake up with a sore back either in the middle of the night or in the morning. Lots of tossing and turning and mornings feeling like I barely slept. The 1” pad firmed-up the mattress perfectly for me. It’s still soft enough when I lay on my side (or my back to watch tv) but it’s got that extra firmness I need when I roll onto my stomach. It’s only been about 1 week but the difference is already very noticeable to me. I’m sleeping through the night and waking up in the morning feeling much more well-rested+energetic. I felt my back pain easing up after the very first night and I knew this pad was exactly what I needed. After a few days, my back and hips felt better than they have in a long time. I can breathe better because my back muscles aren’t so tense. Before, I was stretching my back almost every morning to get rid of stiffness. It’s improved my sleep pattern, energy levels, breathing, back&hip pain. 5 stars ... show more

  • Amazing bed topper!
Size: King Style: 1" Topper
After reading reviews I purchased the 1 inch topper to correct a new mattress I purchased that is too soft. This topper has solved the problem! I had always heard that latex is a harder surface, but this is actually moldable and soft while still being very supportive. I put a padded mattress protector on top of it and it’s perfect. Supportive and soft at the same time. Love it! ... show more

  • Extremely uncomfortable and strong smell
Size: King Style: 1" Topper
The topper has such a strong latex smell that even after letting it air out before use, my body smells like latex when I wake up. We wanted a firm topper because we like a firm mattress but I guess it’s too firm because I’ve never had worse back pain throughout the night. I wake up in tears and thought it was kidney stones the first few nights but now I realize it’s just an extremely uncomfortable mattress topper. I’d return it if I could but my husband threw away the box. ... show more

  • comfort
Size: Queen Style: 1" Topper
I bought a firm foam mattress, but it still made me feel like I was sinking into it. It just wasn't the right support for my back. Adding this latex mattress topper completely changed the feel of my bed. Instead of sinking, I feel like I'm floating on top of the mattress while still getting great support. It has made a huge difference for my back, and for me it was the perfect solution. I'm very happy with this purchase. ... show more

  • 1-inch firm did great for us !
Size: King Style: 1" Topper
Truly excellent product. At first I hated the 1-inch topper in firm because it was TOO firm. But within days it was epic. Restored a two-year old Casper mattress to comfortable and pain free sleep. Zero off gassing. Organic, good for planet. And our bed was transformed with just the 1-inch firm!
