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

Don't get a bed, get this !!!!
Size: Twin Style: 1" Topper
Since I got this, I've gotten a great night's sleep !!! This stuff is what the big company's use to make their mattresses good, and charge thousands of dollars. Buy 3 inches and firm !!!! Put it right on the floor or any flat surface and yer good to go. I've already told a few friends about it, they got it and thanked me for recommending it to them. Some with back issues too, and some without. This company should give me commission !!! Hehehehehe Just kidding... To finish up: I have one of those 3 hundred dollar frames that go up and down like a hospital bed and it vibrates, and this mattress moves perfectly with it too...better then a thick mattress. I've had 2 back surgeries and a bunch of cortisone shots, so a good sleeping surface is what I've been looking for, and I've tried everything !!! I still have an over $2000 mattress that I'm trying to get rid of. This will last for years, decades or how every many years. This has not gone out of shape at all in the last year and a half. You definitely need to get the cover for it though, it's only a few more dollars, but trust me, you'll be happy. And if you need to go on vacation, you roll it up and take it with you. I can't tell you how much it's changed my life !!! 3 inches "firm" is perfect !!! I wouldn't recommend to anyone to sleep on their stomach or side or you'll have back problems down the road. If you don't sleep on your back then maybe get a medium firm or soft, but try and change the way you sleep. Trust me, you'll feel it in old age. See if your grandparents sleep on their sides. Nope...lol Anywho, this is your last mattress you'll be buying unless you own a wolverine. Oh.... Ps: My girlfriend, just told me after reading this, that she sleeps on it just fine on her side, when she does, so....lol...i guess it's good for any sleeper. What the h*** do I know...I only had back problems for years and saw dozens and dozens of doctors... Hahahahahahaha Anywho, buy this bed, it's not just a topper, it's a bed that needs no box spring, as long as you have a flat surface to put it on, or a flat frame thinger like we do. Your welcome ! :-) ... 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

Latex foam is worth the extra money
Size: California King Style: 1" Topper
It’s hard to explain what it is about latex foam that makes it so comfortable but I really makes a Comfortable bed! One thing I’d like to mention is I bought the extra firm and it is not firm in the way you might expect. Although it’s labeled as firm still very soft it is just a bit more supportive. The product came quickly the measurements were accurate. There is a Very slight smell to the product but not really noticeable after a few days of airing out and when under a mattress protector. I love the product! ... show more

A few small rips on original / replacement isn't even the right thickness
Size: King Style: 1" Topper
Update: Amazon ordered me a replacement because the first one had a little damage and the replacement has issues as well. It's off in dimensions all over the place and actually feels like a much rougher material that's missing a layer than the first one.. legit it's almost a quarter inch thinner than the other and is way more squishy, probably because it's missing some material. Didn't even have to take it out of the package to notice a few flaws!! A few small rips here and there but I don't know if that's typical for a latex mattress topper? Hopefully that's not a failure point once we use it on the mattress and apply pressure, causing it to tear more.. 🤷♂️ But overall decent quality, I was expecting the firm to be slightly firmer than what it is ... 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

Jesus Christ
Size: Twin Style: 1" Topper
This is only 1 inch tall. Firm but only one inch. I don't understand how it can be extremely lightweight yet dense yet spongy yet firm and completely supportive without being too hard. The bed I put this on is a school dorm bed. Just springs in a plastic cover- literally more uncomfortable than a prison mattress because at least those are basically thick gym mats. When I unwrapped this I thought maybe they'd sent the wrong thing. It was light, I was expecting something heavy since I knew it was firm and dense. It's bouncy. Do you know that feeling- you're laying on a memory foam mattress, sinking into it, eventually you start to feel like your joins have settled into these little crevices where the foam has sunken in? This doesn't do that. At all. I feel no uncomfortable pressure on any of my joints. I can lay in commonly-uncomfortable positions (I'm a heavy laptop user so I often lay on my stomach with my face jammed into a pillow thats flat because of how hard I'm jamming my face into it) I'm in that position now and none of me feels like I'm going to have to switch positions soon. In fact, when i lay on my back I don't feel like I need a pillow. There are no limits. They should make latex shoe insoles and seat cushions and pillows. In conclusion, this mattress topper and natural latex in general, may be the best stuff on the market. Better than memory foam. Better than a Purple Mattress (And I used to be obsessed with Purple brand stuff). ... show more
