I couldn’t be happier with this Memory Foam Mattress. The quality is excellent right out of the box—it expanded quickly, had no strong odors, and feels very well made. The comfort is outstanding for a medium firm mattress: supportive enough to keep my back aligned but soft enough to be cozy and inviting. What makes this mattress even better is the value. For the price range, it feels like I got far more than I paid for. It’s fiberglass-free, certified safe, and the convenience of having it delivered in a box was just the icing on the cake. Overall, this mattress is a fantastic deal, and I’d recommend it to anyone looking for both quality and comfort without breaking the bank.

EDIT: 3 month update.....I'm still leaving it at 5 stars. We have now had this mattress for just over 3 months and still love it. I am falling asleep faster, staying asleep and waking up feeling more rested. I have slept on both sides and even in the middle of the mattress and have equal comfort anywhere. I normally have 3 dogs hogging the bed and what's really nice is I barely notice if they get up and move to a new spot, even if it's right next to me. I no longer feel like my husband is doing backflips if he turns over in the middle of the night either. Even the one night the mattress pad didn't make it into the dryer in time for bed I did notice the difference the mattress pad makes in not making this mattress feel as firm, but it was still quite comfortable, just not as comfortable. I have no complaints. There were no smells with ours to start with so that never was a problem and it's still at a full 12" evenly across. I'm in the camp of those who were really skeptical of buying a mattress online. Especially a foam one since I've had a regular pillow top one for the past 10 years. Yes it was time for a new mattress! I had been shopping around for a new mattress for a few months trying out different ones, getting pricing and trying to make a decision which is kind of a big deal when you're more than likely looking at spending a lot of money. A friend suggested we consider the foam mattresses and that Amazon had some good prices on them. I headed to a local store to give their version of these mattresses a try and I was surprised how comfortable they were. After testing them out I decided to see what Amazon reviews had to say about the ones they offered. I read through the good and the not so good and the flat out bad reviews and decided to take a chance and see what arrived. I am super happy I did! Granted it's only been 2 weeks but so far we love this mattress! I had read the multiple reviews saying theirs didn't inflate correctly, had a foul odor, was lumpy, etc....thankfully none of that was true of what we received. To break it down..... cons... It is a firm mattress no doubt. I am someone who likes to pretty much sleep in a cloud and am a side sleeper so it's taken some getting used to. Since the cost of this mattress was so good I went ahead and ordered a high quality mattress cover/pad and for me it's really helped make adjusting going from a plush pillow top to a firm bed a lot easier. Going from a spring mattress to a foam ones takes some adjustment on the support on the sides. Obviously the spring ones tend to have more of a frame around the edges so sitting on the side of the bed is different. I wouldn't say it's bad but it's not as supportive. We will probably need to get a new bed frame here sometime soon. While the box springs we had from our old king are still in great shape the lighter weight mattress tends to slide and needs to be shoved back into place every night before going to bed. Not really any fault of the mattress it's just a con that I'll need to replace the bed itself in order to stop this from happening. Another con that's not the fault of the mattress it's just my bad luck....I missed where this was on sale just after Thanksgiving because I was still pondering what kind of mattress to get. So I paid the higher, yet still on sale, price. 4 days later it went back on sale again and has remained $40 cheaper for over a week now. Bummer for me, but still a good deal, just not as good of a deal as if I'd waited 4 more days to decide. On to the good stuff Pros..... Per my experience I say buy this mattress. Don't wait, grab it at the price it is now. I did not notice any sort of foul odor but I did open the windows and had the ceiling fan going while it inflated. It inflated to the full 12" and did so within an hour. We were sleeping on the mattress withing 4 hours of setting it up. It fit where our old king size was perfectly with no overhang or shortages size wise. It's around 2" taller than our old mattress so that took a little getting used to but it measured 12" with a regular school ruler. It was well packaged and fully deflated ready to go when it arrived. I'm a big girl and my husband is a fairly big guy and we both sleep comfortably on this mattress with our 3 large breed bed hogging dogs. When my husband moves at night he does so like a fish out of water and I have noticed he doesn't wake me up turning over because it's not bouncing me around like our old mattress did. I don't even really notice a dog moving around to a different spot. I'm a side sleeper who would love to sleep in a cloud so this did take some getting used to but it's never been uncomfortable. The first night getting to sleep and finding a comfortable position took a little bit but I could instantly feel I was better supported and my hip and shoulder didn't have the pressure it normally would. When I turned onto my back I felt almost like I was sleeping in a hammock. Not totally of course but the extra support was there where it hadn't been before. With what I saved on the mattress I went ahead and bought a nice mattress pad/cover to put on top to make it a little more soft. I had always been told you can make a firm mattress more soft but you can't make a soft mattress more firm so if it's too firm invest in a good pad and it can make a lot of difference if you prefer a softer bed. What I noticed right away is when I woke up I wasn't as sore. I feel a lot more rested in the morning and I'm not waking up to turn over or move around near as much as I was. Granted our old mattress was 10 years old and that had a lot to do with it, but still this mattress is obviously better and keeps me in a deep sleep for longer periods throughout the night. My husband also says he's sleeping better and isn't flopping around like he had been doing with the old mattress. He's the one of us always complaining about being hot while sleeping and he said he hasn't noticed this mattress makes that any worse, and if anything since he's not moving around so much it's better. We like it so much we plan to order the 8" version for our kid's bunk bed here soon. As we get more use of out this I will try to update this review for how it's holding up. I don't expect to get 10 years out of it, granted i probably shouldn't have tried to get 10 years out of the older one but it held up for at least 8-9 of those years. For this price I'd be happy if it lasts a couple of years. If it lasts longer even better. I highly suggest if this is too firm for you to buy a nice mattress pad and to buy it while it's at the price it is now.

We purchased this 8-inch foam full-size mattress for our teenage son, and it has exceeded expectations. He absolutely loves it and says he feels fully supported and comfortable all night long. It's made a noticeable difference in the quality of his sleep. There were zero issues with any chemical smell, which was a pleasant surprise. The mattress came compressed in a box and expanded to full size in under 18 hours—super easy setup with no hassle at all. We’re so happy with the quality and value that we’re already planning to buy another one for our other son. Highly recommended if you're looking for a comfortable and affordable mattress, especially for growing teens!

I ordered this item on 1-27-2018 it arrived on 1-29-2018 with my prime membership. I opened and laid it out on top of a guest room bed to inflate. In 4 hours it appeared to be fully inflated. However packing info says wait 24-48 hours before using to allow proper time to inflate. I did however break down and climb on to see how it feels. I am on a pillow top mattress currently that is roughly 6-8 years old and has been causing me a lot of pain in my shoulder and hip as I am a side sleeper. Just laying on this bed for a few minutes its much firmer than my current bed, and so very comfortable. I will leave a more through review once I have actually slept in it for a few nights. I can say I am very excited. I plan to put it on my current box springs, and we will see how it goes. I was a bit disappointed to realize you cant flip the mattress only rotate it, which is what I have currently with my terrible pillow top . and I like to flip my mattresses every month. I will also state that when I unrolled it I was really worried about it forming its natural state as it had a lot of weird lumps from packing, but it has formed to a normal mattress already on a cursory view of it on my way out the door today. I will better inspect it when moving it to my actual bed. Update!! I have been sleeping on this mattress for about a week now. I will say one night I did get very warm, however I don't think it was my mattress I tend to run hot and cold and occasionally has the same issue with my old pillow top. This mattress is shockingly firm when you first sit or lay on it you think oh Hell No! But within second the memory foam begins to contour to your body and it's very comfortable. I am a side sleeper and was having alot of hip pain with my old mattress. While my pain isn't gone it's much better, and I think it will go away given more time with this new bed. My review is definitely a positive one. For 179$ and arriving in 2 days I'm very pleased. Included are 3 photos the last photo shows me sitting on the edge of the bed showing how much it goes down with my weight, and that I don't know why people say you can't sit on the sides I can't sit on any side any corner no issues... and even with my weight it springs right back to shape once I move or get up, it also still provides comfort and support this bed is rated up to 500lbs! Which thankfully I am not! ********* Updated Review*********** I have been sleeping on this bed for over a month now, and wanted to update my thoughts. My hip and shoulder were in ALOT of pain when I bought my new mattress. I couldn't barely walk around during the day from the pain, now I am fully recovered and I credit my bed for this. If you are on a budget and cant spend 500-1000$ on a new mattress I greatly recommend this item. If you are plus sized and worried about it don't be this bed is tested for 500lbs and as a big girl myself I sleep amazing on it with my HUGE dog and cat. I feel more rested and relaxed waking than I have in at least 5 years.
