  • Love it so much I’m buying a second
Size: Full
We have a Serta purchased in 2007 that is our ultimate dream mattress. So we turned to Serta to replace a different mattress causing a lot of pain. Anyhow, bought this about 6 months ago and LOVE it! Very soft and also supportive. Back/body pain resolved. Everyone in the family approves. I’m actually here to buy another! ... show more

  • Super comfortable!
Size: Full
Was a great choice for daughter’s new apartment! Came packaged and delivered to front door and unenrolled and ready to sleep on the same day

  • Overrated
Size: Twin XL
It seemed to be made decently. However, when it was delivered the box seemed and was like it ran the marathon. On top of that and most importantly it stated plush top. My wife felt it was quite hard and uncomfortable. Nevertheless we returned it.

  • I recommend
Size: Twin XL
I bought this mattress in hopes of it helping my back. It did.

  • Soft but supportive
Size: California King
I was very hesitant about getting a new mattress. I have never had luck in buying pillows or mattresses. I like my bed with support but also soft. This was the one. I'm glad I did go for the 12". I think the 10" would not have been soft enough. I didn't have any problem unpacking. I could have slept on it that night but I waited one more night. ... show more

  • Comfortable Mattress Bought
Size: Queen
It's as comfortable as advertised and good for the price. It was a bit heavy to get up the stairs but that's normal for a mattress, once it was up there it was easy to set up. Just make sure you let it rise for the recommended time before using it.

  • Ordered a queen received a full
Size: Queen
The size you choose is not the size you get, ordered a queen the box even says queen but we received a full, we measured it and it is a true full not a queen, the bed is comfortable and feels great but size up if you’re going to order!
