[This review was collected as part of a promotion.] I received this product for free from Influenster and Sealy in exchange for my honest feedback. The Sealy Dreamlife 12 Foam Mattress-in-a-Box has been my dream mattress! I was instantly impressed with how well they shipped the mattress. The box was so lightweight I was able to carry it up my stairs to the bedroom. As soon as I opened the box and cut open the plastic I just stood in amazement on how fast the mattress inflated. I left it laying flat out on my living room carpet for 24 hours so it could fully inflate. The next day I placed this on my bedrack layed down and I was in heaven. With its Advanced SealyComfort gel memory foam that adapts and responds to every part of your body to provide pressure relief and a personalized sleep experience while SealySupport transition foam enhances the overall comfort of the mattress and adds long-lasting durability. After just one night my chronic back pain has went from unbearable to mild. It has taken off so much pressure off my body and painful areas. The mattress is 12 inches height and 30 inches wide which provides plenty of space and comfort. This mattress has helped me fall asleep faster and stay asleep longer. It is firm has a high bounce and keeps me cool all night and helps me wake up refreshed and rejuvenated! Myself and my husband have had the best sleep of our lives the past week with the Sealy mattress. I can see this lasting us many years as long as we rotate it monthly. I’ve never been a nap person but this past weekend having this bed. I’ve made myself take an hour nap a day just to relief some pain and pressure off my body and back. I have no regrets. This sealy mattress is life changing and will last me and my husband years to come! We are both extremely happy with this mattress.

[This review was collected as part of a promotion.] This bed is a miracle and I have nothing bad to say about it. It's a squishy bed that is super tall and I wanna fall asleep immediately whenever I lay down on it. It's not the most supportive but that's what I like. I definitely think it is worth the purchase and will last you a lifetime.

[This review was collected as part of a promotion.] The mattress is great I replaced it with my old mattress the old mattress made my back hurt every night tired every time I woke up.. Since getting this new mattress I haven't felt my back tired at all. Again it's my savior

Matress is comfortable. My partner likes a very soft matress, I prefer a firmer matress. This is a good compromise for both of us and we are sleeping well.

[This review was collected as part of a promotion.] Inflated and took full shape quickly after being removed from the box. Extremely soft and plush. Comfortable and decent to sleep on but I wish it provided a bit more support to prevent sinkage when just trying to sit on it. Better for side and back sleepers as it's a bit too soft to comfortably sleep on your stomach.

got to help my back im a side sleeper its made it worse

Still adjusting, but seems to be softer than I thought it would be

I bought what I thought was the same mattress years ago, and it was my favorite. This one is definitely not the same. I left it to inflate for 3 days. It's seemed really nice however my boyfriend complained about it being hard. My side was soft. I thought he was crazy... until I felt his side. One side was hard. One was soft and sunken in. It didn't seem to inflate all the way on one side. We did end up returning it. I chose to buy a different brand. Maybe it was just a fluke that it didn't propely inflate. Howevere it didn't go as I had hoped. Better luck to others.

I bought a king Dreamlife Sealy mattress in April 2025. After 11 nights of sinking down so deep i could feel my platform, i gave up and called about arranging a return. Still waiting .... Sealy , Please help

It rose to full height within a few minutes. I gave it multiple days to expand before laying on it. However, I am deeply disappointed with this mattress so far. It sinks right to the transition foam. Per the listing this is a "soft mattress," but sure doesn't feel that way. For context, I am replacing an 18 year old inner spring mattress. This feels worse than the 18 year old mattress I disposed of. I reached out to Sealy and was told to "give it 30 days." Note: once you hit 30 days it's no longer eligible for a "Free Return." And I anticipate returning this brick it to be a hassle. Unbelievable. This is the most expensive brick I have ever purchased. I will never trust the Sealy name for as long as I live.
