Extra Plush, but quite nice
VERY soft. I'm a plush mattress fan, and this is that for sure. Recommend a thin mattress support on top of frame with all beds, especially this one due to softness. Nicely packaged and very easy to unbox. Minimal smell after opening that wouldn't deter immediate use. Happy with the purchase.

Very nice. Plush is better than medium.
I was having restless sleep and suspected my mattress was at fault, I tried out a family member's mattress and felt completely comfortable on it, so that was the proof. That mattress (purchased in 2020) was identical to this one except for being categorized as medium instead of plush. Same 12" height, same Sealy brand, same bed-in-a-box foam construction. What I didn't like about the medium mattress was my calves felt like they were "riding on top" of the mattress, which caused my feet to turn out uncomfortably. I thought if I had to sleep on that, I'd need to put a folded blanket under my lower legs to get the right feel. I just unpacked this new plush mattress today, and in the first moments of laying on it I can feel the difference under my calves, it's just right. The difference between medium and plush is not dramatic, but it is noticeable. Don't be afraid that a plush will feel like a hammock; this has ideal support. It's been my experience that all-foam bed-in-a-box mattresses tend to feel firmer than advertised, keep that in mind when shopping. I was thrilled to find this "plush" one at such an affordable price.

Great ultra plush bed!
I was extremely nervous to buy a mattress online without testing it out in person. I got the ultra plush bed. As soon as I opened it up, I laid down on it, and I know that you need to wait about 48 hours for it to fully inflate, but let me tell you I immediately took a nap on that bed. I have never been more comfortable. It's crazy because while laying in bed I can feel my spine being straight. Even though I'm lying on my side, I've never slept in a bed like that. It is very plush but not to the point where as soon as you sit down you sink and you can't get back up. You do sink a little bit, but it complements your body curves. It's been a really long time since I've been able to sleep this well. Update: I loved this mattress at first but the spring and summer time have been terrible. I literally wake up in a pool of my sweat everyday. I am never hot , and this bed makes sleeping terrible if it's warm out. I even bought multiple mattresses toppers that are cooling and they don't even do anything to help.

Forget Nectar Bed! Get this!!
Hands down THE BEST BED! Guys, I bought a Nectar mattress for my new adjustable base and it literally felt like I was lying on the ground on how hard it was. My sister a few years ago bought an Eco Sealy bed and uses it in her guest room. It felt perfect for me but they don’t sell it anymore. Anyways came across this Sealy bed in a box and I am so so happy with it! My back feels better, my neck feels good, great support. If you’re on the fence, buy it! Oh and the materiel is cooling and great! I sent that Nectar bed back so fast lol definitely happy with my Sealy. 10/10 reccommend!!!

Just right
Goldilocks here, wanting to share that this bed is finally “just right”. It’s soft and squishy and contours all those pressure points just perfectly. I’m happy- finally, after purchasing and getting rid of at least 3 beds in search of this. Price is a steal for how great I have been sleeping. Easy breezy to set up. No weird smells. I got the 12” plush queen.

Best purchase I've made this year
I was skeptical, not going to lie. I was even more skeptical after taking it out of the box. I unboxed it, left for work, and came back 13 hours later to see a huge mattress. Wow, Impressive! I waited another night to actually sleep on it and I LOVED it! I slept so sound and felt rested when I woke up. No smell, it kept me cool, and it's the perfect height. I've been deployed since that next day and literally cant wait to sleep in this again. Definitely worth the money! Highly recommended
