S SECRETLAND King Mattress, 14 inch Gel Memory Foam Mattress,Medium Feels-Bed Mattress in a Box,King Size Mattress

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.

I bought another mattress-in-a-box from Amazon a few years back. It began to get depressions in it and you could feel the inner-springs sticking into your back. Not a good feeling. I will be adding a review for that one, as it is utter trash and the company is too. I emailed them several times and they never responded.This mattress is great so far. It is rather firm, which I like, and I never get up with a backache. It feels more like a good conventional mattress than a bed-in-a-box. I can sit on the edge and it doesn't sink down like the old one. I am 6'6" and about 220, in case anyone is interested.The mattress did not not have any unusual smell at all when opening, which is a typical complaint with many foam mattresses. It expanded well and was usable the same night.My only gripe is that it didn't come with the woman in the ad. False advertising!Pros -- Not too expensive Firm (if you like that) No bad smellCons -- You will never get it back into the box if you wanted to return. This is pretty much true for any of these mattresses, which is why they have a "good" warranty. They know nobody will ever pay to return them.Verdict -- Good mattress for under $300.

I liked that it's comfortable and forms to my body. It took 72 hrs to get to 12". I dislike the fact that I ordered a 14" but it only rose to 12". I felt cheated cause I paid for one thing and didn't get it. I think I eould but it out the store next time and not online

It took a bit to inflate itself, probably about 30 hours it took its fullest shape. The mattress is really soft, you won’t feel any type of support like a hybrid mattress will have where you feel a floor, but that is my preference exactly. It feels like sleeping on a big cloud (I got the king size) and your body sinks in. For the price I feel like I’ve scored a big win.

I have plenty of aches and pains so if I can wake without having any I'm declaring the mattress comfortable and it obviously supports my curves in all the right places. I fell asleep quickly and stayed asleep except for nature calls.You won't get any spring action with this bed since their aren't any springs. The mattress came to life fairly quickly and was ready to sleep on in 24 hours. After a month I don't see anything concaved or wrong with the mattress. Didn't have a strong smell and was packaged well.

Would buy this again. My friend sent a TON on a brand new mattress and says she wishes she's have gotten the one I did because it's so comfortable.

This bed is going to inflate an inch smaller than expected but it is a great mattress. Very soft. I bought it for my three year old and I’ve been in it more than he!

Very comfortable but be aware that it sinks when you lay on it.
