  • The bed so far seems to be functioning properly.
Style: 14" Size: Queen
I am pleased wit the bed. Pay for the delivery to be brought into the house. I didn’t and it rained the day of delivery so I had to drag the box into my house myself as my son was at work. It is heave, I used my rolling pins. See picture. It is amazing they could squeeze it that small, I innately thought I had the wrong size and I knew I couldn’t get it back in the box after I opened it. It was/is a true size queen. My daughter and son in law slept on it over the holidays and they liked it. My cats love the bed and I napped comfortably. 6 cats fit with room to spare. My two boys will not sleep near each other. ... show more

  • The Right Mattress Makes a Difference
Style: 14" Size: Queen
I used AI to help pick a mattress that might help hip pain. I assumed the pain was from too much walking, 6 to 10 miles per day. Nope, it was apparently linking to hip alignment on my prior firm mattress that was due for replacement years ago. I did not like the Sealy at first, but hip pain is gone and after a few weeks I find the mattress comfortable. ... show more

  • It's a good mattress
Style: 14" Size: Queen
Overall I like this new mattress. We purchased it because it is certified to contain safe materials and it's soft top (foam) mattresses are good for side and back sleepers and the lower coils provide structure to prevent the mattress from sinking. Our mattress sits on a boxspring mattress which sits on a bed frame so the mattress top is almost 3 ft above the ground and the edges roll / sink downward when I first get on the bed and in a sitting position with my legs hanging off. Otherwise, I like this mattress a lot. ... show more

  • PERFECT!
Style: 12" Size: King
This mattress is awesome. After trying one out in the mattress store and not wanting to pay 1300.00, I found it here. Husband and I are very very picky and was skeptical about a hybrid after having a pillow top for 20 plus years. But we do not regret buying this at all. It’s not super soft, but not too hard. We wake up with NO back or leg pain anymore. I would give 10 stars if I could. ... show more

  • Great mattress.
Style: 14" Size: King
This is a really comfortable bed at a very attractive price point. It has good support. I get a great night’s sleep on it. Not hot like my old tempurpedic mattress Pay for the in the room delivery as they take away the old mattress and it was effortless. This is comparable to $1400 mattresses at your local store. ... show more

Mattress was way too soft and uncomfortable. Luckily it has a 100 day return policy so I was able to return it.

Comfortable for the first 6 months. After that, I’ve never slept in a bed where you wake up insanely uncomfortable.
