Spring Dreams 9" Two-Sided Encased Coil Mattress, Short Queen RV and Camper Mattress

Update 4, six months use: Still rotating and flipping every couple of weeks. Smoothing out the top foam padding EVERY SINGLE DAY and flipping the mattress more regularly than you would think you should is a must. If you don't, I could see this being a huge problem eventually, as in, it could become so stretched that you'll never get it flat again. Springs still seem fine. Just as firm as the day I got it. No sagging. Yes, it's a lot of work, but poor folk can't be choosers. It's a good mattress if you're willing to maintain it. I got my full size mattress when it was below $200. At the price now, I might do some comparison shopping before I'd buy this one again. I'm still satisfied. I've gotten faster with stripping down the bed every morning, smoothing out the foam top of the mattress and remaking the bed. I just can't deal with a lumpy bed. It's a good morning workout routine.Update 3, three and a half months: Adding pics. The first two pics are during my daily routine of unmaking the bed to "massage" the wrinkles out of the mattress top material. I have to smooth it out with my hands and forearms from the middle to the headboard and footboard areas of the bed. The third pic shows it after it's been smoothed out. If I didn't the rest of the bedding would be ugly and lumpy.Update 2, three months use: I've flipped and then rotated the mattress once every two weeks for the first three months. Flipped one Sunday, rotated another Sunday. That's going by just one method I've found recommending flipping the mattress every two weeks for the first twelve weeks and then once a month after for even wear. The springs still seem just fine. The only problem, which is more of an annoyance than a real problem, is the top outer padding on each side. It bunches and wrinkles in the spot you lay. Flipping it exposes the relaxed, flattened side but the flatness only last a few days. You can sort of "massage" the lumpy wrinkles out but still only lasts the day until you go to bed again. The covering materials are really too soft and weak for their intended purpose. This does not mean the mattress is uncomfortable. Not at all. I cannot feel the wrinkles when laying on the bed. The materials are too soft to feel them. The mattress as a whole is still very comfortable, springs still strong and not sagging. The problem...annoyance is only visual. If I pull my bedspread tight, the wrinkles don't show as much. Still hoping this mattress lasts at least a few years. The outer covering causes my rating to lose a star.Update 1, three days of use: Best sleep I've had in a while. A small wrinkle was present immediately just to one side in the middle, about 12 inches, at the "fold". I flipped the mattress with the side that "opens up" from the compression facing down with hopes that it will allow the wrinkle to relax for a while. I can't feel the wrinkle while using the mattress, it's just visible and with a thin blanket and my mild OCD, yeah. I guess the new materials have to do with fire safety standards but I already know that this jersey knit has a tendency to stretch and bunch. I don't look forward to that. I miss the days of thick, indestructible synthetics used on mattresses, but time inevitably marches on to safety/lesser quality I guess. Still a comfortable mattress so far.Easy enough setup. Very comfortable. Nice firmness. I'm using it on maybe a 1930s-50s era steel Simmons bedframe with the three year old foundation that came with my last expensive pillowtop mattress. It filled out nicely and fits the bed with no real gaps. My standard sheets fit it with no problems. Taut, not loose, not too small for the mattress either. I like the fact that it can be flipped and hopefully without a foam pillowtop it won't be so hot. One-sided mattresses are the worst ripoff scam of a design. I wanted a two-sided mattress again. My last flippable lasted 15 years and it was more cheaply made than this one and used. My last mattress was a one-sided pillowtop. It was done in 3 years, really even before that, even with regular...spinning. What a joke. This one will be on a regular flipping schedule just like when I was a kid. Hopefully that will keep it going for a while. The company seems willing to honor their warranty for defects. We'll see how it goes. I'll be back for an update. Maybe 3 months.

box was open on delivery, but mattress intact and inflated appropriately, it is just too firm with no give.

(The three stars are an average of three different size mattresses; one was bought several years ago - same brand and everything - and two were just delivered.)We bought the queen-size version of this mattress for my daughter about 3 years ago, and it's still going strong. There is a small indent after this long from where she sleeps, but otherwise it is great - soft, comfortable, cozy. The ends cave in a bit when you sit on them but nothing to the point that makes me think it's annoying. I'd give this one 5 stars.We just bought a full-size and a king-size and unpacked them today. The full-size had a slight odor but nothing bad (I don't remember if the queen size had much of an odor either; my daughter said it had a slight one but not a terrible one), and it seems on par with the queen-size in terms of comfort. It's a bit too early to rate this one beyond initial reactions, but I'd say this has a 4 or 5 star rating.The king-size is a different story. I realize it's only been a day, and maybe it needs to be aired out a bit, but the smell is TERRIBLE. I'm a chemist and I'm used to noxious smells, but this is by far one of the worst smells I've smelled (even TEMED smells better; it's on the level of fairly concentrated ammonia) and is definitely making me sleep on the couch tonight. It smells like acetone mixed with dry erase markers, but then multiplied by about 200. It's unbearable. We have the window open and a fan going to remove the smell, but the mattress itself still has an odor that is very strong. I sleep on my stomach and there is no way I'm sleeping on this thing. Considering we waited a month for it to be manufactured and delivered, I'm very unhappy. 1 star at this point.If the smell doesn't dissipate in a day, I'm going to try to return it. It's not useable in its current state - which is too bad, as it seems like it's as comfortable as the queen size. I'll update after a few days either way. In the meantime, it's the couch for me tonight. Very disappointing.
