I didn’t need a break-in period with this mattress. It was perfect from the first night. I have now had it sbout a week and I haven’t had any pain or stiffness. Its the perfect firmess (medium). It feels like you’re sinking into it when you lie on it. You don’t roll off the edges. It requires deep-pocketed sheets/mattress protector.

I have only slept on it 2 nights so far but I slept really well. I am looking forward to perfecting my night time rest on this mattress.

[This review was collected as part of a promotion.] This is honestly the best sleep I've had in years, I could almost cry! This mattress provides a wonderful amount of support. It's really firm, but not stiff. The quality is unmatched and is so durable! The fabric on the mattress is really soft and silky feeling. I have no aches in the morning when I wake up, and notice I don't sleep as hot.

[This review was collected as part of a promotion.] I am so satisfied with this mattress from Sealy. I think this is the best mattress until now in my life. The quality is super and it supports my back very well. It is heavy so need 2 people to set up in the room. This is the best mattress .

[This review was collected as part of a promotion.] Got to try for free in exchange for a review. We’ve had it about a month and it is so comfortable. While it’s labeled medium firmness, I would say it’s on the softer side but we love soft so it’s great for us. It’s a thick mattress about 16 inches, so we had to get a shorter box spring to bring down the height. We also had to get new sheets for it. It provides a cozy, supportive, cool, comfortable sleep, can’t speak for the longevity because we’ve only had it for a month, but I would buy this again. It doesn’t squeak or make any noise.

[This review was collected as part of a promotion.] When i tell you i never expected to receive a Sealy mattress to review , but i did. And omg I’ve had the best sleep, it’s firm yet not too firm, it’s the perfect comfort level, durable, breathable and it’s really makes your night sleep 100% better, I’ve purchased Sealy before and this mattress really impressed me

[This review was collected as part of a promotion.] I have terrible posture and have always wondered about a more supportive mattress. I haven’t slept on it long enough to notice any postural results, but already I’m able to sleep and lay on my stomach again without any lower back discomfort, and my back pain and shoulder/neck tension has decreased which is great. Overall I definitely notice a supportive difference with how my body just stays a lot more straight and aligned. I will say, this mattress is huge. Even though I have a queen size I had to use king size sheets so they would be deep enough to actually cover it and stay on. With it being so large and heavy though they did add handles to all 4 sides to help with moving it, so that’s nice. I only gave 4 stars because I generally prefer a softer mattress and I got the medium firmness, which is still comfortable but I think the soft would’ve been like sleeping on a supportive cloud. And also because it was annoying having to buy all new bedding.

Put the mattress cover on ,it don't fix at all, actually it sucks, on top of that my sheets won't fix .the bed is ok.

I feel like the side wants to sink down and you feel unlevel and like you're going to fall out of the bed. We are still trying to get used to it.

Do not order a mattress from Sam’s Club. I ordered this mattress on December 19. It is now January 27. The mattress has not been delivered. Nobody can tell me where our mattress is. Sam’s has taken the money for the mattress but hasn’t delivered it to me. They can’t even track the package to tell me where it is. There is absolutely no extra value in ordering through Sam’s Club. Go to your local mattress store and get it.
