Comfy

Very comfortable. I’m a mix of side and face up sleeper and I have good support and comfort. The soft pillow top feels great. I feel rested in the morning.

Really Disappointed - inaccurate height

This will be my first time giving reviews, and I am really disappointed with the service. It said 12", but it’s only going up to 10.5”. Contact customer service since March 5 and verify the issue by sending the picture. The customer service said, “UPS will come pick up in 3-5 days." I found out they dropped the label on the front porch. And nothing happened after 5 days. I called again, and the customer service said, "You need to wait 3 days.” I waited again. I called it in after 3 days, and “the customer service said the label has been canceled. And create another one today again. I am really disappointed with the service. It’s really wasting my time.

Comfy but…

The mattress was easy to unfold and expand except for the corners. It’s been over two months and still not completely expanded. It is comfortable but is lower at head and foot sides. Wrote to Sealy customer service but no response.

Amazing mattress

I am SO happy a friend told me about her mattress and convinced me to get the same one!! I can’t leave my bed (in a good way). It’s super soft and the foam molds to my body which I personally love. The best mattress I’ve owned to date yet.

Incentivized review

One of my favorite so far!

Firstly I was very sceptical about trying a mattress from a box. How would that even work?? Let's talk about a package. It's pretty heavy. I don't usually have a problem lifting but I struggled a little with this one since I had to take it on the second floor. I unwrapped it and let it expand. It took several hours but let it go to the full 48h before using it. And i will say this mattress is like sleeping on a cloud. I have a really serious back problem but I wake up every morning with no pain! A little minus was a smell which eventually went away..
