SweetnightMattress, 12 inch Memory Foam Mattress with Three Firmness Levels from Soft to Firm, Gel Infused for Cool Sleep and Spinal Support, Flippable King Size Mattress in a Box, Whisper

If you are heavier or you need a really hard mattress dont get memory foam get a hybrid I have learned there is a big difference having just the foam as to having foam and coils. I bought this its medium to firm and it had two sides firm and plush style. It didnt have a super strong smell considering it made of a bunch of plastic like material and it traveled in the hot Texas weather. I like it done the job got it in king

I bought this mattress after having looked and looked and wondered for weeks if I was going to choose the wrong option and have regret.Other mattresses had polarizing reviews. This one has better ones but some people still dislike it.I will tell you all about my experience with it so far. I bought this one in twin size and it arrived fast and it was all shrink wrapped in a plastic, rolled up and in a box. The box is heavy yes. I took it out in a space with enough room to decompress it, and near where I planned to keep it.I made sure not to cut the mattress when opening. It immediately inflated nearly all the way, but it took another few hours to appear correct. It had no areas that did not get to full height after one day. There was one corner that seemed a bit crushed. I had an idea to kind of help it along by manipulating it a bit and it did get to normal height soon after. This did become its full size. Also, it has absolutely no bad scents or issues with weird materials or anything. It smelled like almost nothing right from the box. It has its own material zip on cover. This is not a bedbug protector type cover, rather just material to keep the mattress a bit cleaner. There were no insect or stain issues whatsoever on mine.this mattress has one side that is called firm, one that is called medium and soft.it has 3 different firmnesses in one mattress. You can tell the difference between them, and firm side is what I used most.It feels very firm to the touch on firm side, but there’s give. I gave it a try and slept on it firm side up. I am a woman who is 5’0 and weighs around 160 pounds. In the places I am heavier like my center and hips I sank into the firm side some, but I never sank down too far, it never hits the bottom of whatever it is laying on top of. It still has mattress under me even when seated cross legged on it.Sleeping on firm side- I have pain in bony areas when prolonged pressure is placed. I do not move much while sleeping, and wake up sore a lot. On this mattress on firm side I have not had pressure or nerve issues even once so far.Over time the side i have slept on has only softened slightly, it springs back up when I leave the mattress and has kept its shape. I have had it about 5 months or so now.Firm side- My legs and arms do not sink in when laying down but my body does a bit. It has given good back support also. Someone who needs slightly less firmness can flip it and use the other side because the other side is medium and a little softer.Softer side feels like it has more give. Not a lot more but some. There is a noticeable difference, but it isn’t completely extreme or anything. What’s different is that the softer side you sink slightly more and it’s softer on areas where your body weighs less such as legs etc.Soft side- also springs right back up when you leave the mattress. It hasn’t lost its shape over these months. I would suggest that if you are placing the soft side down, and are using a daybed or platform that has slats or bars you place a flat surface between just in case to avoid indents but the instructions say it’s ok on slats. I don’t want to risk it. I will tell you what I did even though it may sound odd to some prose. I got several free large parcel boxes from the post office that come flat and slid them flat between my mattress and slats and it has protected it free of charge.However, soft side feels nice if you want a pretty firm option but with more surface give.Neither side caused me pain. I have had less pain in fact. If at any time for some reason you have an injury or pain in places you can flip to softer side. If you like a very firm mattress but like to have something on it, such as a think blanket over it, or a mattress pad, it works that way too. I tried that.Another thing about this mattress is, it does not transfer much motion at all. In fact, I have sat on this mattress on my computer, or phone, and had a cup of beverage or can of soda just sitting there on a different part of the firm side, and it didn’t fall or spill when I stood up and forgot about it being there.The only drawback I might see with a mattress of this type, is it can’t be flipped monthly like people do, without having to use a different firmness on the other side.This mattress states that it has 3 levels of firmness not just 2.From what I can tell- The third level is either at one end of one side and is so you can have less pressure at your head, or legs. Or maybe it is softer to one side. I am not yet certain. Whatever that means it has not effected how it feels in any negative way.If you are in one area on here for a long while and you have made an indent with your body, and you want to move over, in your heaviest area it takes a few seconds to redepress for you. It is not as extreme as on memory foam though. It also has not caused me to feel overheated. It does collect a bit of body heat in the places you are laying, but in my case this is not extreme and has not bothered me.If you like a very firm feel, I think you will enjoy the firm side. Firm side is indeed firm, but not horribly so in my opinion. It’s not like you are sitting on the solid floor or anything, it’s soft but has a lot of support. You will not sink much. It doesn’t bounce around or anything either. If you sit there and move all over the place, items on the bed, like a laptop or blankets, will not be moving all over the place.When searching for a mattress, my fears were that if I chose one that calls itself firm it wouldn’t be. If I chose medium I feared it would actually feel really soft. I feared it would have a toxic odor but it does not. I also feared that I would choose one that when I sat on it my body would depress down until I could feel the floor or platform. I weigh 160 and only sink about 2 inches. If you are heavier I think you will still have mattress space beneath you.when you first lay on this, you are probably going to say to yourself Oh no! I am just laying on top and not indenting whatsoever, this is too hard! The sinking takes time on here. Also after a couple weeks it worked better.If you are a person with an issue in your ribcage area, and you are lighter than I am in weight you may want to use the softer side. I had a sore ribcage temporarily and firm side made it more noticeable but softer side didn’t.i have lung disease and sleep slightly elevated on pillows at times. When I do this is very comfortable.I feared that the mattress would lose its shape fast and keep indents. So far this has not happened. The area I sleep most on has become only ever so slightly softer, and it’s not noticed unless I actually feel around, i’d not noticeable while laying at all and I can update after more time.I am happy with my mattress and glad I got this one. I think I made a good choice for the price range. If I feel like a softer surface I can flip it around. I like having that option depending on how I feel that day or night.I am happy with it.

I hurt my shoulder and neck. Stayed at a friends house that had this bed in their guest room. I woke up for the first time with no spasms in my shoulder. I went home tossed out my $6000 mattress and got this one. Never been happier.

I've ordered 2 different memory foam mattresses in the past for other rooms and love them, however neither are available anymore. So I ordered this one and it is very comfortable, EXCEPT, after only having it 36 DAYS it is totally sinking in where I sleep, and the foam does not bounce back! I had hip surgery (which is why I wanted a new mattress), and for a few weeks when I got in bed I would sit down, pivot my legs onto the bed, and then literally lay on my side, staying that way for the night. Even so, I do not think this type of mattress should form the shape of the body and not come back. Now that I can move around more it is almost impossible to move closer to the center of the bed because it's like trying to go uphill, and when I do totally pick myself up to move that way, it is uncomfortable because of the slope.They say mattresses are returnable, but that is if they are put back in the shipping packages! These mattresses are factory flattened, folded, rolled, and have all the air sucked out of them, therefore cannot be put back the way they were shipped.

Got this mattress over 2 years already, love the options of 3 level firmness. Best mattress I’ve ever slept on & I have back problem. Had guest slept on it & they always compliment the bed.

My husband and I have been sleeping on and putting up with a ridiculously uncomfortable mattress for years. We both have constant back and pain issues, and it finally occurred to me that it was our terrible sleep support. We both work from home and probably spend more time in bed then the average person. I have personally been fighting with a pinched nerve in my neck and shoulder area for the last 3 weeks. So, I began the endless search for the perfect mattress in hopes of solving the constant pain we have had, and a better nights sleep.The mattress was due to arrive in 3 weeks of placing the order, and arrived in 7 days. The Amazon tracking system never updated until it was delivered. I was sooooo surprised & excited to see the box on our porch. The box is extremely heavy and should be carried by (2) people.We opened the mattress packaging in an empty room, and allowed the mattress so rise overnight. It took our specific mattress about 24 hours to reach the full 12". Possibly our kids using it for a trampoline encouraged the process. There were no odd smells, and the mattress was extremely clean.GUYS!!! I am telling you the 100% truth. Once we got the mattress on our bed and we were able to finally try it out. I sat on it for about 15 minutes, and when I got up. I had ZERO neck and shoulder pain. I don't know what is in this miracle mattress. But, I am absolutely convinced it realigned something just by sitting on it. We have opted to start off with the softer side. Like others have said it feels something like a very supportive marshmallow and hugs your body with support. But doesn't suck you in like quick sand! It is still quite firm, super supportive and Im sure will soften up even more with time.I was super nervous to order a mattress I had never seen or felt from a random (to me) company online. I am 110% satisfied with this purchase, and have decided to replace the kids mattresses with the same. I will definitely recommend this mattress to my friends and family, and strongly recommend it to those of you who are searching for the best in quality, solution, and investment. Sweet Dreams!!!
