Sleep On Latex is an all-natural and eco-conscious choice if you want all of the benefits of memory foam, but don't want synthetic foams in your house. Latex is harvested from the rubber tree vs other foams that are made with petrolium or harsh chemicals. With three different firmness profiles, most customers can find what they are looking for initial feel. But, there were some that had issues with long term comfort.
Sleep Science builds a line of latex and memory foam mattresses. Their claim to fame is their 'wedge' technology that provides edge support to every piece of the mattress. Additionally, they are Certipur certified, which means they have low VOC and no formaldehyde in their mattresses. They also use bamboo material in some of their mattresses. Their mattresses are made popular through their relationship with Costco warehouse stores where they are sold at a competitive price vs many of the retail sold mattresses of similar material quality.

We had a very firm serta icomfort that hurt my hips. I'm a side sleeper. Last year we added one of the latex toppers. That helped, but not enough. We recently got a medium mattress and are using it with the topper. It has been great!View More Reviews
The firm is fit for us. I am pregnant, this one helps a lot
It’s a great mattress though mine only is about 8” since the wool and cotton has not yet full expanded. I have great sleep at night, no aches or pains.
We have ordered 3 queen size beds for our new home. Not only do we love the mattresses or guests do too! We also ordered 4 deluxe pillows, which we are not as happy with. They are too thick which make them uncomfortable.
We purchased the firm latex mattress. It is very firm, but we are comfortable on it. As has been mentioned in other reviews, there is a smell to the mattress. It is going away over time, but some people might find it objectionable. It is also a heavy mattress.

Stands up to all the claims made by it's inventor ! Better more relaxing sleep than on any other mattress, hands down. Also, the price is reasonable and the Customer Service is fantastic. !!
In an attempt to remedy chronic back discomfort & having more preference towards firmer sleeping surfaces... I initially purchased a medium 3" topper to firm up a pillow top mattress. When I received it, found that I would've preferred the firm topper as the medium didnt do much. With plans of returning the topper, I decided to go ahead and pu...Read Morerchase a latex mattress, choosing the 7" firm. Interium I slept on the topper placed on a carpeted floor. Those few nights were THE BEST sleeps I had in a long while. Firm enough for me to feel the support of the floor, yet cradled enough by the topper that it wasnt too hard. Also noticed that I didnt wake up with my normal morning stiffness from the pillow top mattress. Shipping for mattress was just as quick as the topper. Upon opening there was a farm animal smell mixed with latex, which was strong enough to be off putting to me. I also noticed sagging in the middle of the mattress once it was laid onto my platform bed. I phoned the company & the customer rep assured me that it would take a few days to a week for the mattress to full expand to its capacity; and if it didn't, they would ship a new mattress. I found the firm to be TOO firm(I'm a side sleeper) & bouncy, so I put medium topper over it. I felt like Goldilocks, it was just right!! Even masking the zoo smell from the mattress. Now having slept on the mattress & topper for nearly 2 weeks, I have to say that I am getting some of the best nights sleeps ever!! Even my housemate commented how comfortable it is to lay on. So I wont be returning the topper, happy to know that if I go thru a phase of needing more firmness, I can always remove it. Oh, I also noticed that the animal smell as calmed down a lot, needing to place my nose close to mattress to detect. I do wish the mattress had handles. I am very happy with my investment, 3 stars for now, will return after 6 months with an update; as only time will tell how well they both hold up from use. Read Less
Solid, way to firm. Will probably return.
Best mattress my wife and I slept on in years. Everyone needs one!
I recently bought a 9 inch Pure Green Natural Latex Mattress and am very happy with it. I wanted to avoid the off-gassing of memory foam so I was specifically looking for a latex mattress.

Queen medium, back and side sleeper. I have back pain after 6-7 hours every time, despite trying all sorts of positions, a soft latex topper, a soft memory foam topper, and pillows under parts of me.

Read a lot of reviews and did a lot of Reddit’ing and couldn’t be happier
This is the best mattress i have ever owned. Its supports my body well and is comfortable too! It is very heavy to move tho.
I got the firm version of this mattress, and it’s great for back sleepers (maybe a little too firm for side sleepers). I’m not giving it five stars because I don’t recall being warned anywhere that the queen size mattress weighs 150 lbs. I’ve since learned that latex is heavy, and I think it’s great for some people. If you’re not on the first floo...Read Morer, you may want to request “white glove” service. Even in the box it took two strong men and me to get it upstairs. I decided to return it, and I’d get the regular instead of the firm if I did it again. I’m opting for a lighter mattress. They offered to let me donate it, but since it’s so heavy I asked that they pick it up. They’re sending people who will carry it back downstairs for me, and they were extremely pleasant and understanding about the return. They’re definitely a quality operation, and I’m sorry it didn’t work out for me. Read Less
The Pure Green is really well constructed from materials that feel durable, especially the primary material, which is a huge slab of latex. I much prefer the feeling of the latex mattress to memory foam, and I like that it's cooler than foam mattresses. Highly recommended.
I bought the medium firmness king size mattress and it is the perfect firmness for me. I have been extremely pleased with my purchase.

I really, really loved this mattress for the first few weeks...it felt amazing compared to my old bed. Now that I've had it for about 8 months, I'm less sure. I bought the medium firm mattress, 9 inches thick. I waffled between firm and medium, and ultimately chose medium after talking to an employee, because I often sleep on my side and some...Read Moretimes sleep on my back and that was the recommendation. It seems like it has already lost a little bit of it's firmness, which I thought was not supposed to happen. After about 3-4 months I started really wishing I had chosen firm. Hopefully it doesn't soften further. Some Pros: The price! I could not have afforded most of the other brands of natural latex mattresses out there. Also, more comfortable than many other conventional matresses. Another issue is the mattress itself is a little (1-4 inches) narrower and shorter than advertised, than a typical full size bed. Maybe factor the thick wool cover into the advertised mattress dimensions, which seems misleading. I know it's just a few inches but it felt noticably narrower to me than my conventional full mattress. Overall, I'm still undecided. I'm happy to have been able to afford a more eco-friendly and healthy mattress. I wonder if I expected too much, comfort-wise. Since I did love it at first, I would kind of like to try the firmer mattress instead...but am worried I'll just be disappointed again. Read Less
Love the mattress, comfortable, safe, clean!
I bought another mattress identical to one I purchased just over a year ago with SOL, this time for my guest room.

It is nice to read reviews that actually are true. My experience has been great with this company and it's customer service. They helped me choose the correct Bed , topper and pillow. I couldn't be more pleased with the Sales Team and the product. Which by the way, is like sleeping on a cloud. The most comfortable bed I have ever had. Thank you
My wife and I loved our old tempurpedic, but started looking around when upgrading to a king size. We were initially attracted by the organic, natural nature of the mattress.

We bought a 9 in medium density mattress, and added the 3in soft topper. This was not comfy enough for my husband's aches and pains, so we are going to add a 3 in down topper in search of a cloud nine rest for him. I like the mattess with the soft topper, and I like that it's natural, had minimal odor, and that it is not friendly to dust mites.
excellent quality and comfort just as I expected
I bought a queen size, 7" firm and so far it's been great. it is a little firmer than I'd like and I'm exploring options with the company.

First impression was very good on the overall quality and comfort of my firm mattress. Very supportive and comfortable.

This mattress is great, we got a medium firmness because so many people said the medium was really firm. I disagree, I think the medium is appropriately categorized and thus we are returning for a firm. It’s super comfy but we have an infant and need a firmer sleep surface. Company is quick to respond and great to work with!
Fantastic mattress! I was very apprehensive about purchasing a mattress online but so happy now that I went with SleepOnLatex. Delivery was straight forward, the unwrapping and installation process was uneventful. The even and comfortable support from the mattress was superb. I told my wife that I felt like I was floating!
Slept on a futon for 2 decades until I got my new latex mattress. Best decision I ever made.
I love my latex bed. I purchased the 9 inch firmer and 3 inch soft topper. Everything is high quality. I mage a V birth bed in our sailboat a decade ago from a king size 6 inch mattress. A local company cut it into 5 pieces that fit like puzzle pieces into more than a king size wide V s shape that was only 18 inches at the feet. I covered it with ...Read Moresilk/cotton blend upholstery. It is a great bed so we decided to get latex for home. It's like it is alive made of a chunk of meat, it's such a natural product.

We bought twin mattresses for our girls. They are super comfy and our daughters have gotten great sleep since they started using them.
We bought the 9” medium mattress with a soft 3” topper. It’s just dreamy! What was great was that the mattress was ready to sleep on soon after unpacking with no off gassing.
I have wanted a natural latex mattress for a few years now. I love the say I feel so refreshed after sleeping on this mattress. The firm mattress is Sooooo comfortable for my wife and I. I will buy another one in the future and will recommend them to my friends.
I am enjoying the new 9” king soft-firmness mattress. However, if you enjoy memory foam, this may not be for you. In fairness to Sleep On Latex, they made that point clear to me when considering my purchase. Latex pushes back more that memory foam, but you won’t sink, either.

met my expectations completely at a reasonable price, now I wake up with no back pains. I tried another product with a sleep on for 100 days and return if not satisfied, I returned it after 11 days.
We were happy with the firm mattress, and I'm even happier with the addition of the 2" soft latex topper, which feels like the ideal combination of support and softness. Great products, excellent customer service; highly recommended!
I've only ever slept on one mattress my whole life, so I dont have much mattress wisdom to offer. The mattress was a little firmer than I thought, but I sleep like a baby on it.
We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.View More Reviews
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.
This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!
I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!
I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!
I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!
I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!
Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!
We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.
Delivery company had great personnel.
One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.
I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!
The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!
Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.
Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'
There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.
