3. Open Cell Memory Foam 2.5"

The Open-cell Gel Memory Foam is proved to sleep 25% cooler than traditional petroleum-based polyurethane.

Quality mattress at a reasonable price!

Absolutely love this bed. It’s not quite what I was expecting but I’m not disappointed in the least. In my mind, I thought it was going to be cloud feel where you just melt into it like those extra soft memory foam toppers. I’ve never been one to like firm beds. This bed is firm but it’s also soft. A nice soft layer at the top just enough to lightly hug your body without melting deep into the mattress. Then firm underneath the top foam, but not so firm that you feel like you’re laying on the ground. This bed has a perfect balance of plush and firm. Motion transfer is great. You can hardly feel any movement/ & can’t hear any sound from the other person in the bed. Not to mention it’s huge. We got the king. The mattress goes slightly over the Zinus frame we bought for it, but that doesn’t affect anything negatively.Upon receiving the mattress, packaging was horrible but it didn’t affect the bed at all. In fact, the bed itself was wrapped up so securely that it could’ve been tossed around without a box & still been In tact. It’s 180lbs too so have a strong one around to help set it up. Probably best to unwrap the mattress on the frame.It expands fast but it’s not finished. It took about 3 hours for it to expand 90% and about 3 days for it to be completed. It expanded to about 11.5 – 12 inches. We slept on it the first night. It gets firmer over the course of 3 days but like i said, it’s a good soft firm, not a concrete firmAs far as the pillows go, they are bulky & firm and a little soft.. firm in the middle. I personally like flatter (memory/ feathered) pillows but my husband loves the ones it came with.As far as chemical smell goes. I really couldn’t tell. There may have been a slight odor but not strong at all and once you put the sheets on you can’t even tell.Seriously couldn’t have gotten a better bang for our buck. I’m really picky with mattresses & have ALWAYS had a memory topper on mine.. and even tho this is firm, it’s just the right amount of plush to keep me comfortable without needing a topper.

Needs to make clear which side is up when you unpack

This mattress is 12 inches and is big. It’s all of every bit of 12 inches and started rising before I could get it all of the way out of the plastic. It was at maximum within 5 minutes. We bought an original box spring to go with it, and I have to raise my leg high and climb up in it. My dog cannot jump on it or get off by herself. I should have gotten a thin box spring, because now my mattress is way higher than the bedside tables. But I DO NOT CARE… I LOVE LOVE this mattress. The ONLY bad thing is the smell. The smell that came with mine was very strong. I have slept on this mattress for 3 nights so far. I can tell a HUGE different. I have lower back pain, and bad hip pain that will shoot down my leg while sleeping. I have also been doing manual labor… and I thank god for this mattress, as I know my back would have been worse on my other mattress. If I lay on my back, it conforms to my back and feels great. If I lay on my side, I barely get hip pain. I don’t toss and turn nearly as much in this. This is close to firm, but nothing like a firm mattress with coils would be. I have not noticed it being hot at all. And I live in Texas and it’s mid summer. I just hope the smell goes away. It seems to slowly be going away. I probably should have not covered it right away and let it air out for a few days, but I just couldn’t wait to get into it. I am so happy with this purchase. I feel like the regular price is steal, and I got it on prime day… which was even more of a steal. If I am already sleeping in this bed so well from day one…. I cannot imagine how much better it will get. I was worried being over weight (215) that it wouldn’t support me as well… IT DOES! I feel like I am sleeping on a mattress that cost 5k. I would say (being that my hips are so bad) that this does well for pressure points. Oh also…. mine is a queen… and I bought a queen box spring. The mattress is about 3-4 inches wider than the box spring is so I just centered it. I love that this mattress fills in the gaps on my bed. My pillow will no longer fall behind the mattress as I sleep.***UPDATE***The smell is still there. I had to put in a Fabrese plug in. I do not understand why this mattress still smells. It’s almost a mildew smell. I love this mattress. I’m not sure what to do with the smell. Sucks I took a star away for it. It still sleeps perfect and I enjoy getting into it. I just want the smell gone.

This is the best mattress at the best price I have ever experienced.

For years we slept on a traditional inner spring mattress with memory foam topper for comfort. I found that the memory foam traps heat. So while the topper made the mattress more comfortable, the heat was unbearable. We bought a Sealy memory foam mattress for our guest bedroom. I found it more comfortable than the old inner spring, but a bit too firm and too hot. The Acesleep Cool Gel Ultimate 12" Plush was the answer. As plush as an inner spring pillow top, but without the eventually troublesome springs that soon cause lumpy mattress syndrome. And, the cool gel works – keeping the mattress from overheating. I e-mailed Acesleep before the purchase, asking them about foam density. I had read to avoid the low density memory foams as they don’t hold up well. Acesleep responded quickly that they use 2.5" of cool gel memory foam on top on 2" of bamboo memory foam and 1.5" of gel infused memory foam above the base foam. When I saw the bag sitting on my patio where the delivery man left it, I was horrified. The bag was badly damaged and the plastic inner cover was ripped open. These things are tightly compacted and rolled for shipping and once unwrapped expand from a few inches thick to the full 12". Since the inner wrapper was torn, one end of the bed had already begun to expand. With one end still compressed, this thing looked like a giant mushroom. I contacted Acesleep and they said to inspect the cover and the foam for damage. If the foam was not damaged, we could keep the mattress and they would send a new cover if needed, or we could exchange it for a new one. The cover was smudged and the foam seemed undamaged, so we unwrapped it. Soon, the mattress had expanded to it’s full 12". We put it in the living room, under the windows for a day to expand. The chemical/foam smell was strong but dissipated after a day or so. Then we moved it to our bedroom and were able to clean the smudges from the cover. Despite the horrible package/shipping, the bed seemed in good condition. But the best part is sleeping on it. It’s the perfect combination of firm-enough support and plush, soft comfort. And the cool gel really does work.. For the first time in a long time, I didn’t wake up in the middle of the night overheated. When morning came, I got out of bed without the accustomed aches and pains. And my wife loved it as well from the first night sleeping on it. Very impressed with the responsiveness/communication from Acesleep.

My Back is Super Happy

Okay, so when I was debating on whether or not to buy this mattress, I read all these reviews and I promised myself that I would attempt to write the very best review that actually described the firm/soft situation with this mattress. It appears that there is no central reference point for firm and soft and everyone has his or her own opinion about what’s firm and what’s soft. So, in my review, I will put what I think is firm and soft before I describe the mattress. I think of FIRM as rock hard — like nearly board-like or a little softer. It gives when you sit down, but kind of snaps back. People seem to think these are good for bad backs, but I have no idea how this is true. When I sleep on a super firm bed, my back wants to die the next morning. Anyway — soft, to me, is laying down on something and it giving a lot — I recently read a review of a hotel I stayed at where I loved the mattresses, but everyone was complaining that they were too soft. I didn’t think so. So, I think I have a preference toward the soft. An in-between, I think, is one of those mattresses that you lie down on and they give at the top, but hold you kind of firm — and I am referring to innerspring mattresses — so keep that in mind.NOW — as for this mattress, which is a memory foam mattress — I absolutely love it and I think that it is a gift from the universe. It kind of circumvents the firm-soft argument, because is just different. I have slept on different types of memory foam mattresses in the past — some that were actually pretty hard, but that conformed so well to the body that they were super comfortable. This mattress feels soft when you first lie down on it. You can press in and you’re like — dang, that’s soft, wtf. And you do sink into it at the hips a few inches laying on your side. Back, too, but the beautiful thing is that the mattress conforms to your body and then holds you, suspended, in a more firm layer right below the very soft top. I was going to go with a memory foam mattress from a leading discount furniture store, but it was $1,400 — this was MUUUUUCH more inexpensive, so I decided to gamble on it — and I won. I can’t tell you if you will win, but it does feel like it’s quality, and it feels better than those other mattresses in a box that are latex and kind of too firm. This feels like a high-end memory foam mattress. It’s probably like an Aldi-type version of a Tempur-Pedic and other people have said that in the comments. I wouldn’t say its quite as nice, but it’s in that type of family.The edge is fine — I’m a big person and can sit on it and sleep right up to the edge and it’s fine. It’s not too hot — I’m a hot sleeper, and I haven’t noticed any difference — being more hot or anything. What I have noticed is that I haven’t laid in a bed more than 7 hours and woke up without my lower back muscles screaming in a decade.

  1. I have never noticed a chemical odor of any kind with this mattress.
  2. Is the side in this bed firm so you can sit on it
  3. Ours were in the plastic rolled up in the mattress
  4. I do not know. What hat I can tell you is that this is the most comfortable mattress I've ever slept on. Very reasonable price
  5. Double check on the pages. It did the same thing to both my mother and I when we were looking but not at the ordering stages. It showed her full size to be more expensive than my queen sized mattress.
  6. No, there was no give to the mattress. It was stiff as a board. I gave the mattress to my friend and he loves it. My friend loves the firmness to the mattress. I'm use to soft, cushy mattress and it was extremely painful for me to sleep on.
  7. I ordered on the 8th of the month and received on the 13th of the same month
  8. You can use what ever size sheets for what ever size mattress you get you do not need to get the sheets that say for pillow top mattress unless you want too.
  9. I sleep on my stomoch too and I like it. It is pretty firm I would say.
  10. Yes we are using king size bed sheets and they fit!!
