We all want a mattress that will last forever, but that is sometimes easier said than done. That said, data on materials, customer reviews, and tests make things a bit easier.

Those with larger builds might find these mattresses to be somewhat less durable.
I was hesitant to purchase Lull, due to the fact of not having access to trying it before buying. However, purchasing Lull was easily the best decision. I find myself sleeping much better each night. The bed is so comfortable! It took me about a week to get used to it. I highly recommend this mattress to you!View More Reviews
We have had our mattress for 2 weeks and me and my wife LOVE IT!!!!!
My wife is sensitive to outgassing from new foam products. A $1600 Serta mattress we purchased a year ago required multiple days of airing before it was "sleepable". However, this mattress (Twin XL) was out of the plastic cover and on the bed and sleepable the same night. The only think is that for a side sleeper, I would have preferred a bit more firmness. However, the mattress is very comfortable and the value is GREAT
Comfortable, easy to assemble and great customer service!
A much better sleeping experience and much better shopping experience too. One of the things I dread about mattress shopping in stores is that the choices are overwhelming and the added high pressure doesn’t help. We love our Lull. We haven’t been able to sleep a full night in the same bed for years. Now we prefer our full versus our queen which is an old mattress. Soon to be replaced I might add. With a Lull!
I have had my bed seen November it's great so far thank you
Best sleeping experience ever.
It took several weeks to see if we would Get all the benefits of the mattress. It Lives up to the high rating for sure Very happy
We had a rather crazy experience getting our bed, due to the shipping company. Lull was on top of it, and handled the situation well. They stepped in, and it was taken care of immediately. They checked it right after ordering as well. We couldn't be more pleased with the purchase.
I can see why they stand behind this mattress is a great product very comfortable lives up to its reputation
I absolutely love my lull!
My wife and I have been sleeping on our new Lull mattress for two weeks now and just love it!! We both used to have back pains and didn't sleep well on our old spring mattress. Back pains are gone and we both sleep through the night! Thanks Lull!!
I went into this with great skepticism. I admit it. I have always slept on a very firm mattress and I couldn’t imagine a mattress that shipped in a box would be firm enough. But after reading the reviews I figured I’d give it a try (the 100 night guarantee had a lot to do with that decision). And I’m so glad I took the leap. Crazy fast shipping! I gave it one night for it to plump up all the way and blissful sleep ever since. I’m honestly sleeping better than ever. I have plenty of support but the mattress seems to conform to every area of my body. Lull lives up to every promise.
I have been sleeping on this mattress for about a month now, nothing but raves from me. I would recommend a Lull Mattress to anyone considering buying a mattress and encourage anyone who has not given a thought to buying a new mattress to change gears. As a bonus, I paid for this mattress one day and delivered the next, can't beat that for service. Let's see: didn't have to go to the store, didn't have to deal with sales people, didn't have to find a way to get it home or pay a delivery fee, the utility of this mattress is incredible, hmmm, musta made a good choice. Best.
Checking in after a couple of months and still so thankful I decided on 'My Lull'. From the first night till now, I continue to fall asleep quickly and never have an uncomfortable position . I am a very happy side sleeper. I never felt the 'adjustment period' from a spring bed to this type of product. What I felt was comfort and simple and grateful full night's sleep. As others have said, my own sciatica disappeared. Proof to me about the alignment of your body makes a huge difference. I noticed it NOT being there after about the 2nd night. That's how quickly Lull showed me how much I needed this bed. I had sciatica for a few months, no idea why or how it started, but no longer a part of me. I also never had the odor from the mattress or packaging either, that some others had and also said left after a few days. I lucked out all around! If you feel you are all wrecked and also have an old spring bed, it's so worth buying this bed. Also the financing plan to make it easier for you if needed as it was for me.
mattress is really comfortable, and have nothing negative to say right now! getting a good nights sleep virtually every single night! love it!
Life’s good wife say s back has nt hurt since we started using lull
I broke my back a month ago and am in a lot of pain. Sleep has been very difficult. Got my new Lull Mattress and was so pleased. First night of comfort and peaceful sleep. The mattress sleeps cool and is just the right degree of firm/softness. The service and delivery was so prompt. Thank you ...THANK YOU ! !
I'll be honest that it took a few weeks to get used to... it's firm... but within that time period back pain went away, sleep got better, etc. - I didn't have to "get comfortable" after using the bathroom in the middle of the night, almost any position was fine. Worth it!
Love my mattress. Best sleep I’ve had in years. Firm, but not too firm. So glad I decided to go with a Lull mattress.
Everything was excellent. It arrived a lot sooner than expected. It was easy to set-up easy and unwrap. So far I love it.
I've only slept on it a couple of times because it's at my new house right now but every time I've slept on it, it's been amazing. I don't have anymore back or neck problems. It's very comfortable, I no longer experience tossing and turning. It's great.
Great, comfortable sleep, and awesome bed.
It is heavenly.
We have had great experiences with it so far. Definitely an upgrade from our old mattress, we love it.
Very convenient, process of getting into the house and on the bed was very simple and easy. Astounded by how easy it was to finance.
Really simple, fast, and easy. And so far we love it.
Amazing mattress. I am really happy with it!
It's fantastic! I purchased it for my mom, so she loves it.
Good experience it was exactly what i expected.
I can sleep on anything, my boyfriend is picky but he absolutely he loves it. I do sleep a little hot on it but other than that it's great.
Very very comfortable. My husband has had problems with his back but now he is getting six hours of sleep at night.
I purchased this for my son, he is very happy and has not complained. The minute we opened it he's loved it. He usually has back and neck pain but he's had no pain from this mattress.
I think the bed is working for us. My wife has a few issues with her back so we are still monitoring my wife's back pain and seeing if this bed is working. I think the mattress is helping us with better sleep.
It's great! Really comfortable. I am sleeping pretty well on it.
Website was good. It's for my daughter. She likes it a lot.
I really enjoy it, it's a great mattress. It's better than anything else I've tried. I love that it's the right amount of firmness. I love that it came in a box and was easy to set up.
It's getting better. In the beginning I needed to adjust, I was having some back pain, but still working it out.
Amazing mattress and Amazing company! I am a professional athlete who competes for TeamUSA and I can't believe the difference this mattress has made in my performance and recovery! If you are looking for a new mattress I highly recommend this one!View More Reviews
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!
