This is our second time getting a mattress in a box. The first was great but didnt have queen size available so we went with this brand. It was just as easy to take apart as the first mattress with no weird smell. It took a couple days to expand, which was fine and we just slept in the guest room till it was fully expanded. Its been around 2 months since we purchased and we have been rotating it like the aftercare directions said, still no complaints. Once its on the bed frame, one person can do the rotating which is great. Its on the firmer side with just enough softness. Our other mattress is still in great condition and I dont see any reason why this one wont hold up for years to come. Really satisfied with this purchase and the price is amazing compared to traditional in store mattresses.

My daughter outgrew her crib and we needed a bed big enough for her to sleep on with us since she refuses to sleep alone. We decided on a full-size bed but needed a comfortable mattress that would accommodate the adult body and toddler body. Pros: 1. Packaging. The mattress came in vacuumed packaging and seemed small at first. I will admit that for a brief second after opening the bag, I had my doubts that this would be 12 inches thick as advertised. I was wrong. This mattress is 12 inches thick and maybe even a little over. Amazingly, it was so well packaged despite its size. 2. Size. After opening the mattress, be sure to let it sit for a few hours to let it expand to its full size and potential. As you can see in the pictures, it is quite thick. 3. Comfort. My daughter is used to the hard mattress in her crib which is what was recommended for infant cribs. My old body prefers a mattress with some plush and softness. The foam allows a decent amount of firmness but remains easy on the back. The mattress underneath my body does not heat up like other foam mattresses that I have slept on. It also allows me to sneak out of bed after she falls asleep without causing too much motion or shake which would wake her up since she is a very light sleeper. 4. Cover. There is a cover on the mattress that looks like it might be possible to remove with zipper although I have not tried to remove it. The cover itself is very soft and I have slept on it without sheets. It does not appear to be waterproof, so I recommend getting a waterproof cover to protect your mattress if your toddler sleeps on it. Cons: I don’t see a con to this at all except that it’s relatively heavy but that’s probably because it is a high-quality mattress.

I bought the twin size for my 12 year old son, and he loved it. I tested it myself as well and it was really comfortable. This is what led me to buy the queen mattress when I bought a new bed for the guess bedroom. Mattress thickness was accurate, the mattress is soft and comfortable, and the entire mattress inflated completely after two days. Make sure to monitor the corners as it expands to ensure the corners can fully inflate. The mattress covering tends to hold the corners down, so adjust the corners once per day after opening to give it room to puff up as you see it expanding. This seems to fix the corner issue in some of the reviews. Hope this helps.

I’d give no stars if I could. Have had for one year and extremely uncomfortable. Don’t waste your money. It’s more of a thick mattress topper than a mattress.

The mattress is of good quality, though more on the firm side than medium. Fair warning, if you want to return said mattress within the 100 days, you will have to do so through Amazon (Sweetnight says they can't assist as the sale was through Amazon) and it is quite the run-around. Waiting to see if we even can. Your best bet for an easy return, if needed, is to return within the Amazon return window. I would rate 5 stars if the return process wasn't so difficult.

So I had an Ashley foam queen size medium “plush” mattress which I had for 5yrs. It was nothing plush about it so I had a 3in gel foam topper which definitely made a difference but as I age through the years, getting up is a chore on its own and my body aches. Finally decided to get a new mattress which was time to anyway and went for a king size since it’s myself and spouse with our two dogs. The size of a king is HUGE and I was worried it wasn’t going to be plush as described but wonderfully enough it is! We have been waking up rested and no aches whatsoever. I am still going to order a 2in gel topper anyway for an extra plush feel lol. I am absolutely satisfied of this purchase especially for the price! Was going to buy a Lucid but this one was more affordable and on sale, can’t beat it!

Great bed at a great price. Have been sleeping on this bed for one month now. In the box comes with a plastic tool to cut open the plastic wrap and as soon as you do, not even 5 minutes later it forms into shape!! The mattress is definitely a firm but with a soft top and a quick response when you push on it so you don't have that sink in feeling. The product is of high quality material and high quantity finishes. it was comfortable and relaxing. The two sides are independent, no matter how how tussle and the turn the other side can be, it would affect the other side, not like the traditional spring loaded mattress, you will tussle and turn from the other side. The mattress I bought last year was an 8"，it's not perfect for me. So I bought a 12" one at the end of the year. My profession is a truck driver.Driving for long hours every day is very tiring for me.I was having such an issue with back pain due to long driving and hurting my back so much. I think it's an occupational disease among truck drivers. now all that pains are no more and I am really sleep like a log .. this mattress the price was wonderful in comparison to other regular stores I checked out and I am quite pleased. I definitely recommend buying this mattress to make the bed EXTRA plush! One caveat, this thing is heavy. Be advised.
