Great mattress so far came out of the box easy enough and decompressed faster than I thought it would. No off gassing, quiet and comfortable. Feels heavy, solid, and firm but not too firm. Great mattress for the price

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.

I tend to be very critical when reviewing a product but this 12" memory foam mattress deserved a good rating. The reasons are for 1. Packaging (definitely matters when it comes to something as big as a mattress that you have to handle on your own), 2. Level of comfort, and 3. Val0ue. I want to also include the fact that I have 4 bulging discs from a bad accident and bought this for the level of support and comfort one gets from a memory foam mattress. 1. The Packaging: I'm not the strongest or tallest person and had no one to help with getting this on my platform bedframe. Oh yes and I live on the second floor of an apartment building with no elevator and slightly uneven stairs. But I was a able to get it done without hurting or straining anything. The packaging was solid and convenient enough to allow for some sliding and scraping of the package prior to getting it into my apartment and still not damaging or dirtying the mattress. I had to pickup this approximately 5'8" package at the local UPS pickup center because my apartment building has a front gate that has to be manually opened and if they had left it in front of my door, it would block the walkway and would most likely have been taken anyways. I also had to rent a Home Depot pickup truck to pick this up, it would not have fit into my 2 door coupe. This would fit into a large SUV with the seats folded down but the box that it came in is approximately 5'8" x 18" x 18" (check the product details for exact measurements) and will definitely not fit into the trunk of your typical sedan. I was able to lift (maybe 40-50lbs?) this and get it into the pickup. Getting this up my stairway was the challenge and to do this I had to flip it from end to end on the stairs. The packaging was a hard cardboard box and withstood the tumbling. Once the box was removed, I found that the mattress was compressed, rolled-up, vacuum sealed in heavy plastic, and inserted into a solid plastic/polyester protective bag (kind of like the carrying bags of sleeping bags). This protective bag kept the mattress protected and was removed by tearing the perforation. It required a little bit of effort, but was doable without scissors. I then had to unroll it with the zipper fabric cover side down, carefully cut the plastic vacuum wrap and that was it. The mattress did have to be flipped so that the proprer side was on the bottom but it was easy enough. The mattress rose to its intended thickness within 24 hours, and most of it within 30min. All in all, the packaging was well done and I was able to set it up by myself without damaging the contents. The mattress itself had a fabric zippered cover that I kept on and I also put the entire mattress into a vinyl zippered cover. 2. The Feel of the Mattress: Comfortable due to the softness yet supportive aspect of memory foam but I could slightly feel the foundation frame underneath. I opted for the 12" mattress because obviously the thicker the mattress, the higher amount of memory foam material as well as the support foam underneath. I read a review for an 8" mattress and the writer mentioned that she would have gone for at least a 10". I put this on a metal platform foundation and I believe that if I had gone for anything less than 12", I would not be giving it a 5 star for comfort. This mattress was definitely supportive and took pressure off of my back and joints. It had enough memory foam material that I sank in some but was supported by the base layer of support foam. For a little around $270 with taxes, I doubt that I would have found a comparable mattress with this level of comfort. Yes, it memory foam is known to trap a bit of heat and I did feel more heat than a spring mattress but I do sleep with the AC on so it wasn't an issue. If you are one that is very averse to heat or sweat easily as I do, you may want to consider a gel infused top. I didn't feel like I was in the clouds but it was comfortable enough with enough actual memory foam for the feel. 3. Value: Definitely well priced. I had visited a Tempurpedic both at the OC County Fair and the price was nearly $2K. This mattress didn't feel as good as that model but for $270, I doubt that I would have found another mattress with memory foam. I had looked at a lot of options on Amazon and for a 12" thick option with Certi-Pure certification, along with infused carbon material to keep it from smelling, this mattress was the best priced out there. Plus, you technically don't need a boxspring and a platform frame could be purchased for as low as $60-$70 increasing the value. So all in all, if you are considering a memory foam option, this one is the one to go with.

This bed is comfortable but beware- its hard as a rock when on a proper boxspring. I really suffered with headache/neck issues for 2 weeks after sleeping on it due to a terrible flat pillow combined with this mattress. I then bought a specialty support pillow, mattress pads (2) and I was fine. So just please be aware, this is a VERY firm mattress. It might not work with your old pillows, so make sure you have a pillow/padding that is adequate so you do not suffer like I did. Otherwise, the mattress is very well made and a quality bed. It was much firmer than I anticipated.
