  • Nice mattress. Be sure to air it out before using.
Style: 12" Size: Twin
We've only used it a few nights, but it seems comfy. Before putting bedding on the mattress, I'd recommend letting it air out for the maximum 72 hours after taking it out of the box. It takes that long to get rid of that "new mattress smell." If you have a covered porch, I'd let it air out there and put the plastic wrapping on the bottom so it doesn't lay directly on the floor. ... show more

  • Soft but supportive - PERFECT!
Style: 14" Size: Queen
I bought the 14" plush and have been sleeping on it for a few weeks now. I like a soft but supportive mattress and this one is SO perfect. It was not hard for two 75-year-olds to unroll and put on the bed despite not having handles (bummer). I highly recommend this one if you don't want a "firm" mattress. ... show more

  • Comfy
Style: 14" Size: Queen
It's very comfy. A bit on the soft side. Not as comfy as the name brand original memory foam mattress we replaced but great for the price and convenience of having it "in a box". No noticable smell.

  • very comfortable.
Style: 12" Size: Twin XL
I can't tell you how much better I sleep because of this mattress. No more aching shoulders causing me to toss and turn. I sleep like a baby. It is slightly shorter than the 80" a twin XL is supposed to be. More like 76".

  • Great plush mattress!
Style: 14" Size: King
Finally a mattress that is super comfortable! Not too firm. It is more on the plush side. You sink into it! We have had it for a few weeks now and it is a keeper!

  • Too soft
Style: 12" Size: King
Mattress was way too soft and uncomfortable. Luckily it has a 100 day return policy so I was able to return it.

  • Happy for cost
Style: 14" Size: King
Perfect mix of comfort and price. Easy to unwrap with 2 people. Then cut open the packaging an it self inflates. The King is really a king. But simple to set up. Quality is spot on and love it in a king size. Second night on this mattress and holy mother of heat! I wake up every hour covered in sweat. Wouldn't recommend for people who sleep hot. ... show more
