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.] When I say this is one of the most comfortable beds I have ever slept on. Me and my husband travel a lot so we get to experience a variety of cozy mattresses and not a cozy ones. On top of that, we have been needing a new mattress because the BR we got 2 years ago has really let us down. In this hunt for the best new mattress, my husband has been calling some of our favorite hotels to see what mattress they had, we’ve gone to several stores to test things out, etc., it’s really been a whole ordeal. Well, when I got the opportunity to test this one for our guest room, I was so excited. After sleeping on it we are OBSESSED. It is so comfy but supportive, it has cooling technology and I really didn’t notice either of us getting hot like we do on our current mattress (my husband will constantly uncover himself). With our other mattress when went through a horrible adjustment period where it seemed like we hurt head to toe. But not with this one! I felt like my back pain was better the next morning from proper support. My neck and shoulders didn’t hurt. I truly felt amazing! This mattress is worth it, trust me! We will be purchasing a king version for our master bedroom!

[This review was collected as part of a promotion.] Mattress is super comfortable. It is made of really good material. I been sleeping on it for the past few days and it has been great. No back pains. Mattress is higher too which I really like. It is definetly worth it.

[This review was collected as part of a promotion.] Sleeping like a baby should the standard of all mattresses.. One did not come with any chemical scent. My kids always like to jump off the bed. This bed has to be strong and durable. I could barely wake up this morning. The comfort and support is top tier .

[This review was collected as part of a promotion.] Love love love this mattress! It’s like sleeping on a cloud. Grear material and very breathable . Great value for the product. No back pain in the morning. Would highly recommended to anyone looking for a new mattress. Well made product and pretty to look at too!

[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.] 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.

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.
