I'm not sure if it takes time to soften up, but so far, the lack of cushion has been a challenge for my husband and I. We've only had it about a month, so it may need more time, but we also may need to purchase a pillow top cover to give it some cushion. Probably not a good purchase for a side-sleeper.

VERY SATISFIED CUSTOMERS HERE!!! We recently bought an RV and the mattress that came with it was hard as a rock, and so uncomfortable. After researching mattresses we decided on this one, and we couldn't be happier. My wife used to wake me up with all the tossing and turning all night like she's in a kickboxing match, but now I don't feel a thing. If I could give it 10 stars I would.

We are 21 days into sleeping on this mattress. Our last mattress needed to be replaced. This memory foam luxury mattress allows you to get out of bed and not have a back ache. My husband feels that is is too firm but he is getting use to it. We are very satisfied with this purchase!

We went to the store to shop mattresses to find out they do not carry Queen size in the store. They advised us to go on-line and order it. The mattress that we received has about a 6"-7" spot on the mattress that appears to be a wear mark right out of the box... Will it matter when the bed is made? No, just a bit disappointed that we have to take something that isn't perfect when we buy new and had to wait to get it...

I like a firm mattress but also comfortable. This one has been good thus far. I have some issues with my shoulder and hips. My arm has a tendency to go numb during sleep. Since I have had this mattress I have noticed that I do not have to prop myself up to get my shoulder off mattress. I am not sure if it is a back related or shoulder related issue but I haven't had the problems since I have been sleeping on this mattress. I would say "thumbs up!"

I honestly was a little worried about getting this mattress. I never have gotten a mattress from a box before. But I read the reviews and decided to take the plunge. However I must say I love my new mattress. It’s firm but still gives some Cush were you need it. My hips used to ache before with my old mattress. Now I sleep like a baby. Glad I made the change.

Needed a new mattress for the guest room. I knew Serta has great products so I jumped on line to Sam's club. In minutes I found what I needed. Received the mattress in less then a week. Put it on the bed and it was just what we needed. Saved money and Time. You can't beat Serta and Sam's price and service.

I have this matress on a zinus memory foam box spring (so it is well supported), but if you put your pillow near the edge at the head of the bed your head and shoulders become lower than the rest of your body. Otherwise I would give this matress 5 stars...i no longer wake up in pain no matter what position i sleep. The matress is really comfortable.

I bought this for my spare bedroom but when I saw that it is wider and longer than the gel foam mattress I have on my own bed I swapped them. It quickly inflated to a full 12 inches and is so far very comfortable. I would say it is medium firm which I like. Will have to wait and see about it's longevity.

I purchased this mattress because a family member also purchased it and loved it. I have colorectal cancer and sleeping became difficult with the radiation and chemotherapy protocols used to treat my cancer. This mattress has been amazing in the comfort, support and coolness. I've seen more expensive mattress, but not better. This mattress has been much more than advertised. I'm very glad I purchased it.
