Signature Sleep Contour 8" Reversible Mattress, Independently Encased Coils, Bed-in-a-Box, Queen, White

It's been about three months now, and I can safely say this mattress is definitely worth the money. This is a very firm mattress, and contrary to what you may have read, it is ready to sleep on the very night you get it. Mine expanded to full height almost instantly.Yes, there is a light "odor", but it is clean and pleasant. The smell lasted a couple of weeks in my case, but nothing offensive. I actually thought the aroma was a nice plus.Some reported that the queen size mattress was a few inches shorter in length. Mine was not. If anything, it has a slight overhang, so perhaps the manufacturer saw the complaints and rectified this already. My fitted sheets fit perfectly with a nice smooth finish.I'm actually a pretty heavy (>270lbs) guy, so sagging was a concern of mine. So far, there doesn't seem to be any. I have been flipping and turning it a little more often than recommended just as a precaution, but after three months, the mattress remains flat and lump-less.Opening the mattress is really exciting and fun. Yes, you have to use scissors to cut off the duffle bag. Don't bother trying to save it. Once you get the duffel off, you have to cut the tape to unroll it. Then you have to cut that inner bag and watch as it practically pops up like an exploding can of muffins!So is this as nice as those thousand dollar pillow top luxury mattresses? Of course not! But does it afford me a good night's sleep for a fifth of the cost? You betcha! Great mattress, great price, and fun to open. What more could you ask for?*UPDATE: I ordered this mattress on November 24, 2014, and today it is April 17, 2016. Guess what? My queen size mattress is still holding up! Keep in mind I'm a pretty big guy that weighs over 270 lbs. I continue to flip the mattress quite regularly, and while there is a small hint of wear in the spots where I lay, the mattress is still supporting my avoirdupois with a firm but comfortable repose. There are still no lumps and still no regrets!*YET ANOTHER UPDATE: So now it's June 22, 2017. I just thought I'd stop back in and let all of you know how the mattress is doing. Still no change to the number of stars. This mattress has been holding up very well for over 2½ years, and it looks great! While there are still no slumps or lumps, I have to admit that it's starting to feel a little less firm than it used to. I still flip and rotate it regularly, and I sleep on it every night. It's very comfortable. If you are on any kind of a budget and need a decent mattress, this is the one to get! I just hope they are still making them whenever mine finally wears out!*JUNE 23, 2020 UPDATE It has been over five and a half years now, and I still stand by my review. The mattress I bought from here has stood the test of time. I'm laying on the mattress as I type this. It might be a little softer than the day I installed it, but it is still comfortable. One thing I thought I'd mention: Early on, I bought a couple of waterproof "bamboo" mattress pads to protect it and wouldn't you know it, the mattress itself still looks like new. It has been over five years though, and the price has gone up. If they are still making them like the one I bought, you are still getting a bargain. Flip it regularly. If you keep it clean, dry, and on a firm support base, this mattress should serve you well for many years.

This mattress is one of the most dangerous items I have ever purchased from Amazon. The comfort provided by this mattress is not unlike chloroform in it's ability to induce sleep. There are some warning labels that need to be affixed to this mattress as to properly warn unsuspecting customers. For starters, a warning that any and all plans for the rest of your day may come to an abrupt conclusion, as you wake up hours later after coming into contact with the mattress. Getting out of bed in the morning may become increasingly difficult and there is a high risk of dependency on the comforting effects this mattress provides. Side effects from use of this mattress include sleepiness, comfort, lack of motivation to start and or/conclude your day, short term comatose lasting up to 8 hours, and episodes of missing time. Should you find yourself unable to part from your bed, find solace in knowing that aren't the only one and that you have been warned.Update 4 months later: Help! This mattress has taken over my life. I rotate this mattress monthly. 4 months later and I can say this comfort has never diminished. I struggle daily to crawl from its clutches. I avoid my bedroom because its siren call is too much for me. This is my favorite piece of furniture in this house.

Ok. so I read TONS of the reviews and was left more confused than when I started. Everything from 'too soft' to 'really firm'. So here is a review that I hope helps someone else. We had a tempurpedic which we hated...felt like sleeping in a lump of clay. Then we got a sleep number which we are pretty happy with. My sleep number is between 50-60, but usually 55. We bought this mattress for a full bed in our guest room. You need to put it on a box spring, IMO. The sides are fine...no problem 'slipping off the edge' as others have mentioned. If it is shorter than a 'normal' mattress, I couldn't tell...fit on top of our box spring from a regular mattress set just fine. I do not find it too soft or really firm. It is firm yet 'cushy' with a nice feel to it. Is it the greatest mattress ever? No, but I don't know how anyone could expect any more from a mattress for this price!! I love that it was shipped to my door in a box that we were able to manage up the stairs and it was cool how well it 'puffed up' and how quickly it did so. One word of caution...It is rolled and wrapped in plastic and then put in the cardboard box for shipping. Be REALLY careful when opening the end or you will accidentally cut the mattress. We used a box cutter and cut open a tiny corner, then pulled and tore the cardboard till we could see inside enough to avoid cutting the mattress.

Not sure why others are saying this is a soft mattress. I woke up in agony after using it. I have had to purchase a separate mattress topper to make this usable. I wish I could return it but too much trouble.
