    • Arrived early and exactly as described....well almost....
Size: Queen Style: 10''
This is my second "bed in a box". The first one lasted 14 years, so it was just a matter of choosing. After reading SO many reviews I settled on this mattress in a queen. I've kept the old mattress for the guest room. When unboxed it I didn't see HOW that pancake was ever going to reach anything approaching 10". After 36 hours we're at 9.5 inches and the corners a fully inflated. The cover is VERY nice and I expect that missing 1/2 " will show up in a day or so. Even if it doesn't, this is a great mattress for the price and very firm and comfortable, but a caution , if THIS is "medium firm" , Firm must be cement. I love firm and this fits the bill for me. High quality, NO odors and exactly as described. ... show more

    • SO WORTH IT
I just purchased the King sized version and I gotta say I love how I slowly melt in to the bed NOT sinking but melting. So basically it hugs your body so nicely. It is true to size and the bed quickly opened up to 12 inches and I LOVE it I’ve had it for a few days and I can actually sleep I wake up now no back pain. So many upsides to this mattress very affordable mattress very comfortable for me it is firm but I can also feel that plush factor when I melt in the bed. All I can say is give it a try don’t go and spend hundreds or thousands. ... show more

    • 14" King. Honest Review
Size: King Style: 14''
I never write reviews, ever, but I have to write one for this mattress. I was so skeptical at first, I'm so used to having to go lay on every mattress in every store and usually wound up paying a huge price for one. This is a firm mattress but soft, If that makes any sense. I love this mattress, this combined with a nice Amazon basic mattress pad and a heated mattress pad its like my dream mattress. If you have back issues and need a firm mattress and not something you feel like you're sinking in and curving your back they way your back dosent like. This gives great support but is so comfortable. I will admit it has only been a week or so and my old mattress is on standby in the spare bedroom. But If this has longevity I will proudly throw that Sterns and Foster to the curb. Time will tell but I hope this helps someone. Oh and, after I opened it, I let it sit for 3 days in the spare bedroom and I would peek in on it every few hours. Talk about skeptical. It is exactly 14" thick and its beautiful when fully expanded. Like I said, the only thing I worry about is 6 months from now but for what I paid, It was well worth the risk. ... show more

    • Initial Review
Size: Queen Style: 10''
Ordered this mattress along with a Secretland bed frame for a guest bedroom. At this stage I cannot make any comment on the sleep quality of this bed as no one has slept on it yet. What I can say is that the ordering and delivery process was simple and fast. The mattress came delivered vacuum packed as most memory foam mattresses do. Once it had inflated again, the mattress cover is nice material and zipped so it can easily be removed for washing. The mattress doesn't weigh a ton like some mattresses, so is relatively easy to move by one person. I have laid on the mattress and feels very comfortable as MF mattresses do feel. Compared to my own MF mattress, I would say it is more medium to firm. ... show more

    • So far so great!
Size: King Style: 14''
Was a little bummed as shipping took two weeks longer than the original estimated time. Which was partially why I bought off Amazon. Not a huge deal though. After finally receiving my mattress I love it! Was a bit worried with all the mixed reviews but I honestly love it. Being a pretty big guy (240) the support is awesome. If you’re looking to lay down into a cloud this isn’t the mattress for you, as it is definitely on the firm side. However I sleep like a baby in it. I move around a fair amount in my sleep and this mattress accommodates every position. No smell out of the packaging. And expanded to the full 14in.

i just now got my mattress, so don't have a lot to say yet (gave it 4 stars, cuz so far, so good ;) ) ... 1st, i want to acknowledge the local UPS guy - he went above & beyond! i had a path all cleared to the bedroom, expecting to be dragging the box thru, but the guy offered to bring it right in, set the box exactly so & even offered to stay & help me set it up! i said thanks but i know they're busy & was grateful he brought it all the way in for me :) ... i immediately set about to opening it so it could start expanding/airing out ... i did NOT notice any unusual odors (yet anyway) ... i did notice as i was unrolling it that it was very cool (probably a result of the vacuum packing) ... it looks almost inflated already, but i have it up on its end in the window - so the top of the mattress is getting the fresh breeze & i have 2 old fans (on their last legs, the neighbors were throwing out) blowing at what will be the bottom when i lay it down - i'm hoping all the air circulation might prevent any of the horror stories i've read about these types of mattresses :O ... it seems the bigger the mattress is, the more prone it can be to unpacking problems (mines a double/full) ... so fingers crossed that i don't experience any negative effects the way some have :/ ... the storms we were having have all blown over to Honolulu, so Hilo atm is sunny & dry & warm - optimal conditions for mattresses like this to re-inflate - + i opened it right away upon receipt, so hope that helps, too ... when i have more info, i wish to update this - until then: fingers crossed! ;) ..... ..... ..... it's only been not quite a day; mattress seems to be inflating well, tho i've noticed some lumps & bumps in the base foam only - i'm hoping that's due to the fact it hasn't yet had a chance to fully expand. i haven't sat nor laid on it yet - i want to make sure i give it at least 3 days before putting any weight on it ... ... ... ... ... today marks the 72 hrs! most of it's decompressed to about 14 1/2 ", tho some parts are still at only 13"; still some bumpiness in the base foam --- am gona give it a few more days before i sit/lay on it cuz i imagine having that much foam sucked down to a few inches & then go thru the shipping process for X amt of days is traumatic to the foam & it takes some time to recover (putting any wt on it seems like i'd just add to problems :/ but i lived w/out it this long so a few more days or so won't bother me) - still haven't noticed any unusual odors, so i think all is going as it should be, am just giving it more than the recommended 72 hrs to see if the shorter areas plump up & i think the bumpy ridges in the base are just parts that are still compressed & need to inflate - fingers crossed! lol ... UPDATE after having it out of the box a few wks now: well, i have sat on it & laid on it to check it out & it seems like it's gona be comfortable - but i still wnat to wait a while before sleeping on it every night! ... the hard lumpy bumps ARE smoothing out the more acclimated it becomes! i think it's just gona take time, after all, it was squashed/sucked flat to maybe an inch in thickness! LOL ... one end has actually expanded to a bit over 15"; the other end isn't quite 14" (so far!) but i'm _not_ complaining: it's supposed to be healthy for us to sleep w/our feet slightly elevated than the rest of our body (better heart circulation; helps dispel fluid build up in legs, feet; etc benefits you can google :) ) so i intend to make the higher end the 'foot' of the bed (tho the other end may continue decompressing & gain more height) i also am thinking: there's probably more lumpy-bumps inside the mattress that i can't see & they still need time to adjust from being a large thing, sucked into a tiny space, then needing to re-expand back to it's original size! that simply cannot happen in only a few days & i fear putting any weight on it will interfere w/this process - so i'm content to wait even a couple months before sleeping on it, & hope it doesn't ever develop problems i've read about on-line - as long as i can be patient & let it fully acclimate & decompress as much as possible after the trauma of it's compressing, i think it may be a very comfortable mattress for some years! ... the company also seems to be thoughtful & considerate. ... show more

    • Very firm not much (plush) as described
It is a good mattress, but I’m a side sleeper and this isn’t a “plush” mattress. It has very little give and is very firm. I will have to buy another topper to get comfortable. I have been waking up with numb arms. It’s quality, but should be described at FIRM
