  • Bubble bed
Style: 14 Inch Size: Queen
This bed is comfortable, but it feels like there’s a slight dome shape to it. Like someone really heavy needs to sleep in the middle for a week. I’m hoping as we sleep on it, that will improve. But other than that, it’s a comfy bed, fluffed out nicely in 12 hrs. Good deal for the price

  • Well done!
Style: 12 Inch Size: Queen
The media could not be loaded. Great thickness, firmness all right, I wish it was softer, fits well 100lb female and 210 lb man, sleep good, not sure about heat retention.

  • Easy to unpack and super comfortable!!
Style: 14 Inch Size: Queen
Buy a mattress online is not an easy pick but this one was absolutely perfect! Right in the middle as indicated . Not too firm not too soft . Great quality, super easy to unpack , no smell and I no need to “wait” to use. Overall, great money for value . Not sure for how long it will last but so far so good . ... show more

  • Comfy but smells horrible the first week
The mattress smelled like a tire factory out of the packaging. we had to air it in our garage for 72 hours, then bring it in put deodorizers and an air purifier in the room with it for another 72 hours before we could make the bed and have our son sleep on it. If returning it was not a huge job, we would have. But we put the work in, and the mattress is comfy to him now. *Update* - the mattress edges begin to sag after a couple weeks of use from an average size 10 year old. Also, the seller sent a message offering a refund, then retracted and offered less. Bad product, bad seller. STAY AWAY. ... show more

  • Best mattress for the price
Style: 12 Inch Size: Queen
I was a little scared to order a mattress this inexpensive, but it doesn't feel like an inexpensive mattress at all. It's really comfortable and supportive. We purchased for a vacation cabin, and I couldn't be happier with it. It is as comfortable as our expensive mattress at home. Since this won't be slept on that often, its durability won't be tested by us. Hopefully, someone else will be able to review that aspect of it. ... show more
