SweetnightKing Size Mattress, 14 Inch King Memory Foam Mattress in a Box, Double Sides Flippable King Bed Mattress, Gel Infused and Perforated Foam for Cool Sleep and Pressure Relief

This is the 2nd mattress for another room. I set it up myself and I am a small senior woman. It took me awhile but I got it done. I set it up and no smell at all. I couldn't resist sleeping on it the 4th night and just couldn't wait to sleep in it. It's soft but you don't sink. No fiberglass in this. My other one is a couple years old and still sleeping well for someone else in the house. It is the same thing. It got to 13 inches that first day and by the 3rd day it reached the 14 inches. I was happy with the other one and I am positive that I will be happy with this one too. If it gets too soft then I can flip it. I learned with the first that it might start to sag in the first 6 months. I turned it. By the time I hit the 2nd 6 months the first side had expanded back again. So don't worry if it sags and you need to turn it because by the time you need to do it again it will have expanded back up again. It is slightly softer than the first but I started sleeping in it the 4th night and didn't wait for the 5th night. Probably best to wait, but it feels good. I have sciatica, herniated and bulging disc with spinal stenosis in the lumbar spine and it is soft but still supportive enough. It is what I would call medium soft. Not firm and not too soft but just right for me. I weigh about 140 lbs but it feels perfect so far. I would recommend waiting the full 5 days if you need it a tiny bit firmer. But so far for 3 nights I have slept well. The only problem is that you will not want to get up out of such comfort and want to stay there longer. Lol. I would recommend this mattress. I may get a twin for the spare room later on. I will be choosing this one to buy when I replace the one in the spare room. It is not hot sleeping at all. But you stay cool in it. I give it r stars and if it changes it will probably be 5 stars since this is the 2nd. Just because I don't want to get up out of such comfort and I sleep later cause I love sleeping with this mattress. It is worth the money. It is the exact same as secret land but they no longer carry the 14 inch but it is the exact same thing as sweet night. Both are sheer heaven to sleep on. I don't know if it is as durable as the first but I think that it should be. I gave my mattress to someone handicapped that could not wait until it expanded. So I gave him mine and he loves it as much as I do. I am sure that this is the exact same thing. The longer you let it expand it firms up more. But it's great for my back pain. My back has to be surgical fixed but I know when I get out of the hospital that sheer heaven on earth to sleep will be here. Maybe it will finish expanding while I am in the hospital. No worries cause either way it feels good. It's what I would call just right. Not too firm but has support. Not too soft to sag in. But just right. Hopefully when the time comes to turn it, that side will expand back like the first one did. After all this is memory foam and it will usually expand back again. So don't worry if you need to turn it cause my first one had expanded back again. So when I had to turn it again it was back up again. Zero smell to this. Didn't have with the first one either. One thing for certain is that I will never buy a regular mattress ever again. I love the memory foam that sleeps cool. This or secret land is the one to buy without hesitation.I decided to give it the extra star because each night I t still feels perfect. Even though I used it a night too early but I already had one for a couple years and I still loved it. I don't see falling out of love with this mattress anytime soon. In fact I talked a nurse in the hospital into buying one. She clicked on it and read all about it and she liked the fact that everyone said that the company was very good with customer service. I know that I won't ever buy anything but memory foam again. It still feels perfect after a couple weeks. I couldn't wait to get out of the hospital just to sleep on my mattress. So that nurse starts asking me about it. She had a very expensive mattress that was about shot. She had purchased it right then. Lol. It's still just perfect for me. But I had another which was given to a stroke victim paralyzed on one side and after he tried it he said he wouldn't ever give it up. So I know that after a couple years I will still be happy with the new one. The first slept so well I never will get a regular mattress again. It doesn't sleep hot. It's just perfect. So I decided to give it the extra star. Even if it goes down after months and you turn it it's going to go back up again. So when it's time to turn it again it's just back up again. So don't worry about it sinking after time. It might, but just turn it and by the time you need to turn it again it's back up again. So it always feels perfect. But I am definitely sold on memory foam mattress. I won't sleep on anything else again.Just buy this mattress. I sleep better than ever before. I have been sleeping on it and it didn't sink in at all. I had spine surgery and it sleeps perfectly. It's not too hard and not too soft and the sides don't bend down. It is an amazing product. No use looking at another. No fiberglass. No smell to it at all. I couldn't wait to sleep on this one. I am an older woman and I did it by myself. It expanded to the full 14 inches. It is just the perfect thing for people who have back problems. It is not hot sleeping with this. I usually get hot sleeping on memory foam but it sleeps cool. It is the perfect mattress. I recommended it to a nurse who bought it due to the recommendation and she loves hers too.Look no further. This is the perfect mattress. Buy it.

Ok editing to say that it's definitely soft and comfortable and I'm sleeping good on this mattress. I've been sleeping on it for almost a month now and I'm really happy with it. I have it on my adjustable bed frame and it is awesome. I and loving it. Haven't tried the other side but this soft side is amazing. Ok so I just got it today and it's been up for a little over 6 hrs. It's already come up to 9 inches and I ordered the 10 inch. So that's a good sign. Let me start my saying this is my second mattress from Amazon. The first one I got was the a Zinus 12 inch memory foam mattress medium firm. Well I used it for 6 months and it's a great mattress made super great and fluffed up within 24 hrs and I've been sleeping on it for 6 months now but it was a little firm for my liking. So I looked and looked for a medium plush mattress and I picked this 10 inch memory foam by sweet night because it's flippable and you can use the soft side or More firm side which I really love. I'll start by saying it's definitely most definitely much much softer than the Zinus 12 inch memory foam mattress and it's at 9 inches and still has quite a few hrs to go before it's at its full 10 inches but it went quickly to get to the 9 inches but since I already put it on my adjustable bed frame I'm going to sleep on it tonight even though it recommends to wait because I don't have anywhere else to sleep comfortably tonight. I'll update my review on this mattress but I just wanted to let those who prefer a softer sleeping mattress that this one definitely is super super soft compared to the first one I got on here. I didn't sleep horrible on my Zinus 12 inch memory foam mattress but like I said I just want something softer because of my back issues. So I will definitely update this review and let you know if I'm keeping this one in my room or if I'll be going back to my Zinus 12 inch memory foam mattress. Like I said I didn't sleep horrible on it just wanted something softer. Ok bye for now

Great quality mattress. Perfect combo of firmness and comfort!

Very comfortable and great value!! Definitely would buy again expansion happened over a few days and if you rotate it like it says it will full open just fine

It's great but I would keep it on the floorFor better support. Otherwise, you might have problems with just plank supports?The bed keeps it's shape and very well made. Also keep a decent cover to protect fabric.

Unboxed and let it sit for 48 hours. Put it on our bed and we are loving it! I’m a side sleeper and I have no hip pain. My husband said his back feels better. I’ve never been a stay in bed person but this mattress makes me want to stay in bed! Great for the price.

After reading hours and hours of reviews, I decided to go with this mattress. I went with the 12in queen. We got the mattress and followed the directions. Easy to take out of the box. And we almost didn't need 2 people. One string person could have set it up. He didn't sleep on it for 48 hours. We didn't even sit on it at all during that time. He slept on it the 3 night. It finished fully "inflating" by the 4th or 5th day. He said it was so comfortable. He weighs about 140lbs and is 6ft 2in. if that makes a difference. I think it might because of the memory foam. We used the box spring that came with bed frame to begin with. We just added a matterass box spring in hopes to extend the life of the mattress. My son slept on it with the Box Spring for the first time last night and he said it is even more comfortable than before. So, after 2.5 months we are still happy with this purchase. My son likes his mattress a little more firm, and he says this is nice and firm while using the less firm side. He never even flipped it to the more firm side yet. BUT again, he is 140 lbs. I would for sure by another one. I am not sure I would buy a king, only because the weight of the foam has me wondering if it will sag quicker. Just a guess, no experience with that happening. So happy we bought this! I think we paid $330 dollars, so if it lasts 2+ years that is more than a great deal in our eyes.
