  • Don’t miss out on this awesome mattress
Size: Full(NEW) Style: 12 inch
I have spent so much money on very expensive mattresses and woke up with an aching back. This mattress is super comfortable, the price is super reasonable. If you’re looking for a wonderful, comfortable mattress, I highly recommend this. I bought two full size and two queen size and my entire family really enjoys this mattress. It’s super plush and takes a few days to fully expand. It has a beautiful design. I am very happy with this purchase and the brand. 10/10!!! ... show more

  • Quality Comfort
Size: Queen Style: 12 Inch Firm
Good sturdy, quality mattress. I let it decompress for 48 hours as instructed. It is as described. My son weighs 228 lbs and he finds it comfortable and supportive. This mattress makes him feel fully rested. Only issue I see that I don’t like is two of the four top corners bend down slightly. Otherwise, I’m pleased with the purchase. ... show more

  • Soft, not medium
Size: Full(NEW) Style: 12 inch
Given this bed of three only because it's my bed now and I have to get used to it. It was delivered as stated easy to unpack but hard to get up my stairs. This bed is very soft and if you have a bad back it's not going to do you justice.

  • Nighty Night
Size: Full(NEW) Style: 12 inch
Bought this for my granddaughter and she loves it! She says it is very comfortable and she sleeps soundly all night. It was heavy and expanded just like they said it would once I removed the plastic. Great product for the price!
