Most customers feel great in their mattresses and rated them well. However, some folks didn't have the same feeling. If you are thinking about purchasing one of these, make sure to read more about these mattresses below to make sure it will work for you.
Overall, support is important for spine alignment and overall comfort of a mattress over the long term. Most customers describe these mattresses as having good support, but some may have complaints if they are heavy or have wide shoulders or hips.
Edge support is an absolutel must for folks looking for the best mattresses and for those with mobility issues. These mattresses are competitive when it comes to edge support, but some heavier folks may experience more contouring along the sides.
Bowling Ball & Density Tests
Using a bowling ball to measure the firmness and support of a mattress is a common practice. These mattresses offer solid support for most customers, but some customers may have issues with even support long term.
Having a mattress that is durable is very important to shoppers, but some companies don't put the same attention on durability. The good thing is that these mattreses are above average when it comes to longevity. Most customers will continue being happy about their mattress after 5 to 7 years, but some heavier folks may see their mattress degrade faster.
Looking for a new mattress isn't easy, but finding one that has a good reception from customers is a good starting point in finding out if it is right for you. Sleepers rate these mattresses highly versus others. Read on below for the customer reviews and mattress specifics.
Having a supportive mattress is the key to a healthy night's sleep. You want something that will align your spine rather than causing you nightly pain. These mattresses are well supportive.
Edge support is one of the most important things to folks with mobility issues or enjoy sitting on the side of the mattress. These mattresses are supportive along the edges and don't suffer from too much contouring versus the center.
Bowling Ball & Density Tests
A popular test for reviewers, the bowling ball test provides a good indication of firmness while also showing evenness of support across the mattress. If a mattress isn't even in its support, some may find the mattress uncomfortable. Luckily, these mattresses offer good support across the mattress surface.
Having a mattress that lasts a long time can means thousands of dollars in your pocket. And that totally aligns with why durability is so important to mattress buyers. That said, lots of brands are more concerned with profit. Even still, there are some brands that do a good job making durable products. These mattresses are experienced by customers as being highly durable. These mattresses should do well for you unless you have a bigger build or use the mattress more than average.

All I can say is: get it and try it. You will love it.
I got the mattress and immediately fell in love with how well it treats my back. I can sleep most of the night on my back, with little to no need to toss and turn. My sleep on this mattress definitely feels more restful, and I don't wake up with as many aches and pains. I had a concern with a seam on the mattress, and the customer service was superb. All my questions and concerns were treated patiently and professionally, and met with outstanding resolutions.
I would not hesitate to recommend this mattress to friends and family. I am happy that they offer such a great return policy, because even though I didn't end up needing to use it, it made getting the mattress feel like a safe decision.
I have had the OSO queen size mattress for about 3 months now, and I wanted to wait for a few months before rating it. My wife has had back issues for about 15 years and it seems like we have spent thousands of dollars trying to find the right mattress. We have tried every kind of spring mattress and even tried other memory foam mattresses. My wife has not been able to have a decent sleep in a long time often waking achy and tired. When we received the OSO mattress in a box, very neat by the way, I opened it up and let it puff up for a few hours before bedtime. We tried the firm end the first night and found it was a little too firm for my wife, so we rotated the mattress to the soft end. After three weeks of sleeping on the soft end my wife was still waking up with a sore back, which worried us. But, after the three weeks, she started sleeping longer than her usual 5 hours a night. It was gradual, but now she is up to a 8 or 9 hours of sleep a night and she is loving the mattress. I guess she needed to work out the kinks from the previous bad springy mattresses. Based on how my wife is feeling these days, I would highly recommend this mattress.
Thank you OSO for your amazing design!
I'll admit it, I was a bit worried about buying my mattress online. I mean, who wouldn't be?? That said, I could not be more pleased. I have had the best three nights of sleep I have had in years, and it's legitimately due to my new mattress. I love the plush/soft side, and my Boston Terrier loves the firm side!
Seriously - thank you for providing an affordable, well-built, non-toxic, comfortable bed.
I have had major numbing in both of my arms while I sleep since 11 years ago. I awaken numerous times a night and have to reposition my arms so they will wake up. My husband and I received our OSO mattress a few months ago. The first morning after sleeping on this mattress, I woke up and realized my arms were not numb. Every night since then has given me the same results. I am so happy to finally sleep and not have the numbing issues I was having. I just can’t believe how much of a difference a mattress would make. Thank you!!!
My husband and I have been sleeping on our new OSO for a couple months now. The setup was super simple. The mattress is supportive yet soft. Our favorite part is that we don't disturb the other person when moving/shifting! So glad we invested in quality sleep.
I really appreciate the option of using the soft or firm side of this mattress. I prefer the soft, and find it very comfortable to sleep on. My wife and I are able to move on our side of the bed without causing much noticeable disruption to each other. We are very impressed with our new OSO mattress, and are very glad we made the purchase..
We love our OSO Mattress. We bought it after reading a friends review and thought we would take a chance. We are so happy we purchased it. No other mattress has been this great, it offers support while still being soft and comfortable. Thanks OSO!
This is the first mattress that I've ordered that was delivered in a box and I'm never going back. It was quick, free shipping, and I was able to open it and lay it out easily. I love how soft it is and how well I sleep every night! I will never go to another mattress.
I'd forgotten the experience of a true, undisturbed 7-8 hours of sleep! But I have it most nights on our new OSO mattress. My shoulders sink right in given being a side sleeper and I'm totally acclimated to the soft side. Very happy with the experience!
We purchased this bed for our toddler daughter as her "big girl bed", and not going to lie, we are all a bit jealous of her at this point! It is so soft, but just firm enough for a toddler! It is actually also perfect for cosleeping, not to firm or too soft. We have another bed made by a similar company and this one wins by a mile. Recently my mom came over and layed in the bed saying her back hurt. After getting up she felt so much better she literally ordered the bed the next day! Big fans over here...clearly ;)
I've had probabaly 7 different mattresses in my life and this has been the greatest! I wake up feeling refreshed and not sore like I'm used to. It's quite an upgrade! Thanks Oso!
The OSO mattress is extremely comfortable - it is nice and soft yet still supportive. I like the removable/washable cover, which will make it much easier to clean when needed. I would highly recommend trying one and would not hesitate to buy another the next time I need to replace or upgrade a mattress!
This is a great mattress. This is my second foam concept mattress. I will never go back to the traditional box-spring style. It really provides support where it is needed most. I would highly recommend.
This bed is amazing. You will not find a more comfortable or versatile bed at this price!! 10/10 would recommend.
The mattress arrived ahead of schedule in a box that was smaller than I expected. The sales person I spoke to when buying the mattress told me that we should move the box into the room before opening it. We put the mattress in our frame on top of the box spring and as soon as we cut into the plastic the mattress started expanding. The vacuum seal is unreal on these things! Within two minutes we had a regular size mattress. This mattress is absolutely perfect for our guest room! When I called my mom to ask if she preferred a hard or soft mattress for her visit she was grateful to have a choice (she picked soft!). Thanks OSO!
My OSO mattress is seriously amazing! I love the option between firm and soft and honestly, they both feel great!
Whenever I have friends stay over, my favorite thing is that I can't feel them move at all! I would definitely recommend this mattress to everyone, especially to anyone sharing a bed!
Worth every penny!!
I had terrible back pain and then started taking tylenol before bed. That helped some, but I would still get up with back pain. We got this new mattress and I haven't had to take Tylenol for my back and I now wake up without pain and can finally enjoy my day!
I got my new OSO mattress two weeks ago, and have loved every night of sleeping on it. I've woken up without ANY back pain, unlike the tightness I had every morning on my old mattress.
I also love the versatility of being able to choose soft or firm! I had no idea what my preference was, and the OSO made it easy to take the leap because I wasn't forced to choose. (I've been sleeping on the soft side.) And with their return policy, I had even more peace of mind.
This bed is amazing!!! When it first arrived I unpacked it and laid down a few hours later (after passing out immediately on it) I moved it to my bedroom. I would and have highly recommend it to anyone!
My husband and I purchased our king sized OSO mattress about 2 months ago. We have been thrilled. The set up was simple and getting it into our condo (up stairs and around corners) was no big deal with the creative packaging concept. It also had no chemical odor when we unpackaged (which I was concerned/skeptical about).
We sleep on the firm side and both love it. It is as cool as it claims (no waking up with a sweaty neck and back). I also struggle with poor circulation and arthritis and used to wake up every night with limbs that had fallen asleep/very achy from the bends and pressure points of our traditional mattress.
I have had significantly less issues with the OS0 and feel comfortable highly recommending it for arthritis/back pain. When it's time to purchase again, we will stick with OSO and never go back to a traditional box spring.
We are happy to finally have a mattress that is quiet, and comfy to sleep on. For years our classic mattress would bounce and make noise with every turn.
The OSO is like lying on a soft raft, supporting the parts that need it most. We like the "firmer' end now but anticipate switching to the soft end as we want- I enjoy options.
If you buy an OSO, buy sheets with regular pockets (not deep) for a smoother, unwrinkled look.
Love the versatility of soft and firm. Moving it in was so great compared to moving out our old king (traditional mattress).
Overall we like the mattress a lot.
Ive had a Sleep Number for years me and my wife like it. But... even with 20 levels you still particular for no reason feel like you are sleeping on an air bed at your moms house lol. We got a California King OSO, to replace the Sleep Number California King. This was a great decision, my wife was so in love she sleep through her work alarms. Its a great bed, id recommend it to anyone.
I've had my OSO now for over 7 months and couldn't be happier!
At first I was a little nervous purchasing a bed online. However, the 101 Night Promise helped me make the plunge! I loved being able to try out the bed in my own home to make sure it was right for me. I currently use the soft side, but knowing I can change over to the firm side if my preference ever changes is very comforting.
In addition, as a (somewhat) recent college graduate who is prone to moving every few years, the flexibility of the foam mattress and portability (being able to fold it and transport in my compact car) is also a huge plus.
I usually wake up 1-2 times during the night. With this mattress, slept completely through the night. Materials look super high quality, love that I could fold it up to get it through doorways.
I love the Oso mattress. There are some nights when I need to lay on the soft side and other nights when I need more support. I don't have to worry about needing a new mattress for different needs. The Oso mattress has also been very kind to my back after major surgery. I love it!
I've had a king size mattress for a few weeks now and this thing is amazing. I have never owned a foam mattress before and this is a great introduction. I love that you can choose what side to sleep on depending on how your body is feeling that day. Top notch!
I’ve never really had a comfortable mattress before so this has been one of the best decisions we've ever made! I’ve struggled with back pain for a few years and my pain has significantly been improved and I feel a million and one times better during the day!
The first night we tried the mattress we slept on the firm end and had a great sleep. The next night we slept on the soft end. We slept ok but it just seemed too soft. Even sitting on the bed putting socks on, it was just too soft. We would love a mattress that was completely firm.
Very luxurious feeling mattress, yet with a sleek and modern design. I really liked the handles, made it easy to move into my apartment and it's lighter weight. I started with the firm side them switched to soft. Love my OSO mattress! Would highly recommend!
The most comfortable mattress I have ever owned. I also recommend getting a latex pillow.View More Reviews
My wife and I are very happy with our new Spindle Natural Latex Mattress. We have been sleeping on it for over two months and it has lived up to its promises. Set up of the mattress was quite easy once all the layers were unwrapped and the cover was laid out on the foundation. I assembled our King size bed by myself in less than 30 minutes - and I am not a big guy. The mattress is stable and very supportive. There is very little motion transfer when one of us gets in or out of the bed. The edges of the mattress are firm enough and we don’t seem to leave any imprint after a full night’s sleep. And as advertised, the bed does not get overly warm during the night. Overall, we are very satisfied!
We bought this bed for my 4 year old and everynight I lie in bed with him and want to stay all night!! He loves it too ;)
I am so happy with my purchase of the Spindle mattress. I searched and searched and having a more natural, nontoxic mattress was important. I tried 2 other brand mattreses, one hybrid spring/latex mattress that was just tol hard and felt it pushed upqard and one all latex organic mattress that was clmfterble but the stitching were horrible and had the worst smell. Then I read about Spindle and just lived the idea of having a zipper and then having tje option of adjusting the comfort layer. I interacted with Neal both via phone and e-mail and he was always super nice and answered my queatione (that were many) and gave me lots of information. I was a bit cincerned about the smell of latex since I had a bad experience with one company but felt it was worth the risk. Having a latex foam that is poured in USA also appealed to me rather than having a latex foam that is poured in Sri Lanka for example and then shipped to the USA. Receiving the covers and the latex layers, I found it easy to put together the mattresses we got one XL twin in firm and one XL twin in medium (to put together as one king) My husband and I both liked the firm and I ended up ordering one extra layer firm. I think my husband will qant to have the extra firm but we are holding of for now. I love the mattresses. The smell is actually nice, like a sweet smell. The feel is great. The cover is also so soft and zipper is of good quality. I could not be happier with Soindle. I highly recomend their mattresses. I also want to mention that the mattresses fits perfect nezt to each other where there is almost unnoticible that it is 2 twin XL and not a king. I thought to put a 1” topper on it but we might not. However we do have a waterproof cover from naturepedic over it, it is not thick but maybe helps a little bit. Thank you to Spindle, I sleep so good, a very supportive mattress for my back. I am 5’4”, weigh 120lbs.
Excellent Mattress. First time that we have ever slept on a Natural Latex Mattress. Great Company. The main reason I purchased from Spindle Mattress is the fact the when you call them you actually are connected to a Live Person not a voicemail system. Also the fact they are 4th generation Mattress Company. Again let me emphasis the importance of answering a call. Something that has been forgotten in Business. We were so impressed we purchased another mattress within 3 weeks.
We are very satisfied with the mattress. We are sleeping very well, on the mattress and not in the mattress. We received it promptly and it was fun putting it together. We added a monster frame to raise it off the floor a little more. My wife was interested in a Temperpedic mattress and I was able to convince her to get one made of natural rubber. We are both happy we bought the Spindle.
No lie, I actually look forward to going to bed. Best purchase ever!!!
Love my spindle mattress. It's incredibly comfortable and very cool. Perfect mattress. Best one I've ever owned. I also own a Casper and I used to recommend casper to friends, but now that I've tried Spindle's mattress, it's all I can recommend. Much more comfortable, the Spindle provides support in all the right areas and like I said before, does not get hot! Absolutely love it.
I don't "feel" the mattress under me, when I sleep.
best mattress I have had so far.
Great mattress giving great nights sleep. Much better feel compared to memory foam. No 'wrap around' feel which makes it harder to roll over.
We are super happy with our Spindle mattress. We are now lifelong customers!!!! Thank you for a superior product and service.
Highest quality mattress you will find. A bargain at twice the price.
We purchased two mattresses, one for our son and one for ourselves, and we all really like them. The customer service is excellent --- we needed help determining whether a mattress would fit in a bedframe and had some questions after we received the mattress, and Kim and others at Spindle took care of everything with patience and good humor.
It was easy to put together and was comfortable from day one. Natural latex is the best option for me and anyone who wants a good night sleep. Glad I made the decision to give it a try.
I spent 17 years on a box spring bed and 10 years on a water bed followed by 2-3 years on a futon then 20 years on a Select Comfort air bed. NOW, about 1 month on a natural latex bed which I have found to be close to a perfect sleeping experience from day one. AS in the story "GOLDILOCKS AND THE THREE BEARS" this bed is: 1. Not to soft; 2.not to hard; 3.ZZZZZZZZ.
Absolutely love the new mattresses! I was a little hesitant ordering 2 without having any experience sleeping on a latex mattress before, but I sure am glad that I trusted other reviewers and went with my spindle purchase! It is the best feeling knowing that my family is sleeping on a truly non-toxic mattress that is also super comfortable!
Fantastic customer service and product. All questions were answered in detail. Very informative and a great company to work with!
I've had a Tempur-pedic brand memory foam mattress, and a store-bought latex foam mattress, but this Spindle mattress is the best mattress I've ever had. Highly recommended.
Love this mattress, and we are picky! Quick delivery. Easier to put together than we thought. We are sleeping very well. Would absolutely get it again.
Amazing. I’d never tried latex before so was a bit worried but all the research I did suggested it was a good option. It’s easily the best mattress I’ve ever slept on. Will never go back to a regular mattress. Also I’m 6’1”, 195 lbs and I typically like a firmer mattress but found the medium spindle to be perfect. Much firmer I think would be too firm.
I decided the firm mattress was what was most similar to our other latex mattress. After two weeks of use it turned out to be a bit to firm so I ordered the topper with cover in a medium firmness. The comfort adjustment was perfect. Now resting comfortably. The topper came in the cover, was easy to get out of box, lift onto existing mattress and provided a little extra height which was nice additive. Love the Spindle product and highly recommend it for quality sleep at a very reasonable price.
I did a lot of research and ultimately chose Spindle. I liked the idea of adjustability and their use of clean and natural ingredients. I purchased the base, too, and was quite pleased at how simply and solidly it went together. I was able to set-up the mattress sections by myself, too, with the aid of the video. The comfort and support of the mattress has been everything I could have hoped for. I wish I had made this purchase years earlier! Thank you, Spindle! Great product!
I like the Latex mattress very much. It distrubutes the weight of my body very evenly. I am comfortable enough but still I feel I want a softer, more plush feeling. I plan on buying two (2) more from Spindle but I want to buy the right comfort level. I will not know unless I try the softer level. I plan on sleeping on this mattress for awhile longer to adjust to it for a longer time to be sure on this end before I make a final decision. I heghly recommend your Latex mattress and your service. Kim counciled me and was very knowledgable of the produc, informative to met and has very good people skills.
It’s very comfortable we are very pleased thank you
perfect choice for us - medium firm
She said, "I never imagined a mattress could be so comfortable". I said, "When I get up, I'll take the cartons to the junk room. We're not sending this thing back".
We LOVE our new mattress!
I LOVE MY NEW SPINDLE MATTRESS! I did extensive research but it was a bit scary purchasing without trying it first. Kim, at Spindle, was so helpful - he answered all of my questions and educated me on various aspects of latex mattresses. I highly recommend this company for the quality of their product and for the care they give their customers.
This mattress is wonderful. I have not felt this good in years. The service was perfect received it very quickly. I am very happy to be able to afford a latex mattress thanks to Spindle. Bought Spindle base with mattress and my daughter and I put the bed together in a snap. I very big Thank You to Spindle.
no breaking in period just a great sleep
I needed a new mattress, and after much online research, purchased a mattress and foundation from Spindle. The foundation was difficult to assemble as the alignment of some of the holes and pegs was slightly off. I managed to get it securely put together, but it wasn’t easy. (If you buy a foundation, be aware that the slats have a white strip connecting them down the center—don’t cut that when unpacking!) The mattress assembly was much easier than I expected, and didn’t take me long at all. I watched the assembly video on Spindle’s website, but I also found it helpful to fold the sides of the mattress cover down over the foundation so I could better align the layers. When I felt the latex in the cover, I was a little concerned the (medium) mattress might be too soft, but once it was zipped up it was fine. I appreciate that I can rearrange the layers if I ever want to firm up. As for smell, the latex had a very mild, pleasant scent which is unnoticeable once zipped in the cover. The foundation and mattress covers both had a relatively strong (clean!) sheep smell from the wool. I shook both of these outside and laid them out in a spare room to air out overnight. I only noticed the scent once or twice afterwards. It was very much a natural smell—there were absolutely no chemical odors. The mattress was comfortable from the first, but it still took about a week to really adjust to it. Since then it’s been great. Overall I’m very pleased with the mattress and foundation. I would buy from Spindle again, and I would recommend them to others looking for a natural latex mattress.
I bought and put together the box spring, but I think it needs to be put on a frame. It is low to the floor and doesn't have back board or front board, if you know what I am talking about. It has taken me a while to get use to it because it doesn't have the spring that I'm use to when I sit down on it. It is definitely different than a bed.
Awesome natural mattress, no VOC smell. Supportive in Medium Firmness, could have even been a bit softer for my tastes. Sleeps cool. With 2 people, assembly not difficult.
A bit harder than I'd hoped for. Seems like good quality. Have had it for about 2 months.
Natural Latex Medium Spindler Mattress; not as great as I hoped for, and not as bad as I feared...Best part, not sleeping on a Chinese toxic chemical waste dump....
I have had this mattress for nearly two months now, and am still not sleeping well on it. I bought it based on previous experience with a latex mattress topper - my bed has a regular old firm mattress and a 2" medium/firm latest mattress topper. I thought that going all the way - plus the natural cover - would be even better. I used the firmness selection tool on the website to select my firmness, and ended up with Medium. It came very quickly, and with three people it was easier to put together than I thought. However, it is far far stiffer / firmer than expected. I sleep on a mix of my side and stomach and it makes my arms fall asleep sometimes. I wrote an email to Spindle about the firmness, and the owner replied with a "stock" email about how it takes time tibfet used to, etc. This email was not helpful. I have now slept on it for nearly two months, and went back to sleeping on my old mattress configuration and slept MUCH better - solidb uninterrupted nights of sleep. So, I am still dissatisfied with the mattress. I am most dissatisfied with the web sector tool, which does not seem well-calibrated -- for example, it asks for BMI in fairly wide ranges, and I think these should be narrowed to make sure lighter people get the right thing. Also I think the tool should come with more caveats or descriptions of the mattress for people who sleep different ways. In my case, an even mix of side- and stomach-sleepin weighing less than 130 lbs, the Soft would undoubtedly be the way to go. I was also frustrated with Spindle's
