This mattress is wonderful for my elderly parent. We have it on an adjustable bed and it is just the right amount of firmness vs. softness. The workmanship is really nice and it is an attractive product. My parent is loving this mattress.View More Reviews
The first night on this bed was the best nights sleep I've ever had. Its like angels made my bed personally using magic. Im truly in love and completely satisfied.
Best mattress I ever slept on. Always had the expensive pillow tops but either to hot or back problems. I love this mattress.
Called manufacturer about return if necessary, and related costs. Remember, it's MUCH bigger if I have to return it. Beware: if u happen to not like it, u will pay over $100.00 shipping, plus incurred costs if u have to get someone else to take this FULL QUEEN size mattress to the shipping point because u can't lift it! Thought u might want to know.
Excellent. Did take some days for it to unwrinkle.
AAAAHHHHHHH!!! A little too soft.
Well know I am ready to review my King Memory Mattress, we have had this mattress for 18months and it has been Awesome!!! I highly recommend it.
Bed hurts back. No support
Nice looking bed, but take note that it is ULTRA FIRM - which is fine if that is what you are looking for. Took several messages to get a response from company and told that customer is responsible for return shipping. Since mattress is inflated to full size - freight shipping is several hundred dollars so we ended up keeping it for spare room.
I purchased this bed because it was listed as medium firm which is what my last dynasty mattress purchased 8 years ago was listed as. This mattress is much more firm.
Slept on it 3hrs after opening from the vac seal. My girlfriend and I Did not notice any smell and slept great same with our 70lb pit bull..Lol Shocked that it was just as comfortable as my $3000 sleep doctor bed that was less then 2years old and also that's the best bed I've ever slept on. Only reason for getting a new one was because it was a split king. I've had back problems for over 10years (2 hurniated discs, fractured vertibrea, muscle spasms and sciatica.. hinse the split king zero gravity adjustable frame. Now that my back is bettrer I can sleep flat now with this new king bed. I dont have to worry about waking up in the crack anymore!!
I had high expectations for this mattress! It is uncomfortable and leaves ridges where we sleep. Yes, I turn the mattress every couple months, and the ridges just become more ridges on top of the old (now sideways) ridges. Very disappointed and hunting for a new mattress!
Enjoy my new mattress, it is soft to the touch but firm enough for good support. My shoulders feel a lot better where they was achy. Both mattress and free pillows expanded to full size within minutes wheras it says that it made take up to 72 hours. Pleased with my purchase.
Our guests love this mattress and told us it's extremely comfortable. Laid on it ourselves when we first got it and were shocked it wasn't as firm as the other ones we had bought. It's been a month and we think the mattress has fully filled up, which it's now firmer than the 1st day we bought it. Comfortable.. we always recommend dynasty mattresses to our friends & family!
mattress is NOT PLUsH but very Firm !
Horrible mattress! Very firm! Like laying on a board. Have the worst neck and backaches! Plus there is no cooling gel. It gets very hot to sleep on. Will be sending this back. Very disappointed!
Took all my hip, back and shoulder pain away!
The Dynasty Mattress arrived in a box and handled well with a 2 wheel cart. The box it came in was marked soft and almost no odor when expanded. We listed our 5 year old 1800.00 Beauty Rest sagging Mattress for free pickup on Face book Marketplace it received 20 calls and was gone in 2 hours.I weigh 240 lbs and my wife about 170 . We have no backaches since we bought this mattress (from everyday backaches). We have had this mattress 5 months with no sag. We are in our late 60's and sleep all different ways ( side stomach back close together )The mattress feels firm but, compresses the right amount for a good nights rest. We do have a padded mattress cover. Yes we would buy this high mattress again.
First I want to say there is nothing wrong with the quality of the mattress. My issue is that this falls in the firm category and I was looking for something plush. As a side sleeper this fact has caused me excruciating back pain. If you're looking for an inexpensive, quality, firm mattress, this isn't a bad choice. If you want something to sink into after a long day, keep looking. I balanced all of my 220 lbs on the heel of one foot and sank in all of 2 3/4" I of course tried to tough it out and break it in as most mattresses need some time and only succeeded in running past the return date, not that I'm sure how that would work as it expands to about 5x it's shipping size once opened. I've purchased a better, much more expensive mattress locally and will resell this one to someone who will enjoy a firm bed. There was a slight odor as expected when I opened it, left it in the garage for two days and it aired out just fine, no complaints there. I may have gotten a defective one, but I can't even call this medium, it's very firm.
I will never buy another spring loaded mattress again. This bed is amazing! Last night was my first night sleeping in it and I slept ALL NIGHT without any issues. It's super quiet, I didn't sweat at all throughout the night also you cant feel the person next to you move which is great. My baby is 4 months old and every since I was 3 months pregnant my hips and lower back have hurt so bad from my previous mattress (BeautyRest aka Trash) , but this morning was the first time I got out of bed and wasn't sore, achy and, stiff. This mattress has brought me long overdue relief. And it just keeps growing! I love it and highly recommend it. Also I didn't notice a smell and the pillows are amazing too
I’ve had this mattress for almost a month now. I am pregnant, so sleep doesn’t come easy these days, but this mattress is awesome! I can still feel some of my boyfriends movements when he tosses and turns, but it’s a huge improvement! I’m not sure how cool it is, but this is my first experience with a memory foam mattress. Mine came with 2 pillows. Be sure and get yourself a waterproof protector to protect your investment. That is a must have!
Have tried it for a month. Not worth money. Sagging around edge and in the areas we sleep. Also back hurts worse than before. Hopefully they have a hassle free returns/refunds.
Awesome bed. We sleep so good! Great buy. It is heavy so have some help if moving it upstairs.
I can't say anything bad about this product, including the 2 free pillows! Its soft yet firm, no chemical smell, rose within 3-5mins to full size, is relieving my husband's back pain, is not hot at all. We are in love with the product.
Best Mattress ever!
No major smell as reported by others. Took shape quick. Very comfortable. Time will tell about durability.
This mattress is so comfortable u can't go wrong . We wouldn't trade it for anything super soft
Too firm. Definitely not a plush.
Amazing.. great quality sleep on firm mattress. Perfect fit. Meets all expectations, already recommended it
The Mattress was delivered Friday, and set up to expand for 72 hours, we slept on Mattress Saturday evening but it's sagging in the middle!
I was looking for a thick mattress that wouldn’t leave holes in the bed from where you lay. It springs right back up. True definition of memory foam and bonus pillows were awesome! Didn’t have chemical smell but does need some time to inflate after coming out of the box. Love how thick the mattress is!
I was aways old school coil spring mattress guy. Wow so glad I tried the new foam gel. Delivery in a box of a queen size bed to your door. Crazy! It's pretty heavy getting the box upstairs but two people can handle it. Unboxing was easy. When you cut the plastic off be careful not to damage. Then get out of the way for the expansion. The two pillows could be over looked they are flat under mattress. I had opened it about 4:00 and by 9:00 it grew to pretty much full size. It took a night or two to get use to the new support. I use to toss and turn all night with cover's all wrapped around me and sore back. Now don't remember going to sleep or that morning is here already. Very happy with it so far! My son is buying one now.
This is the most comfortable mattress I've ever slept on. It's a bit too soft bit overall it's comfy. The price is amazing and my back is no longer stiff in the mornings.
I love the mattress! It's firm but still has a nice give to the memory foam. The chemical smell took forever to go away otherwise I would give it 5 stars.
I haven't slept on it yet, but it seems that this thing keeps growing and growing. I purchased it for a Bookcase storage bed, needless to say, I will have to purchase a step stool to assist me getting on to the bed. To the touch, it feels good, but I won't know until I actually sleep on it....... as soon as it stops growing. Update: Today is day three and the mattress has grown to 14 inches and has another half inch to go. It is big and tall and very heavy. This is the third day of it being on the bed and it does have a musty chemical odor. I still haven't slept on it or climbed upon it, but I will leave it on for another two to three days to see if the odor goes away (open the windows) and to see if it will complete the growing process. I will either send it back if the odor doesn't dissipate or buy a bed step stool to climb this mountain. See the images.
I've been searching a while for a good brand mattress and im so glad I found this brand. I love this mattress, it is better than my old Zinus foam mattress. It does have slight chemical smell at first then it goes away. Came in big box, airtight. It inflated in 30 mins. Id give it a 7 on plush scale and a 7.5 on the firmness scale. Doesn't feel hot like my old mattress too. Def worth the money.
I can finally sleep directly on my side again! No more twisting my upper body opposite of my lower because my expensive pillow top spring mattress killed my shoulders and hips!
I am so happy with this purchase! The bed is amazing!
This bed is awful. We loved it for 2 nights and then it turned into a rock. If you wants a soft or even remotely plush bed this is not it. I wake up sore every morning and reverted back to my old bed while this mattress sits in my storage.. I would just sell it off but I wouldnt wish this waste of money on anyone. And when you try to reacj out to the company to try to find som kind of resolve, they compleatly ignore you. Do your self a favor if this.is your only bed option and sleep on the floor because this bed is the WORST.
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!
