  • So far so good
Size: Twin Style: 10 Inch
So far, so good! After two nights of testing, this twin mattress is off to a great start. It offers a nice balance of comfort and support, and the quality feels durable. No initial sagging or discomfort—just restful sleep. I’ll update after more use, but for now, I’m impressed with the value!

  • A very comfortable mattress
Size: Queen Style: 12 Inch Firm
My waist is not good and I cannot lie on a mattress that is too soft. I just want to find a bed that is both hard and soft. This bed perfectly meets my requirements, and its price is not very expensive. In other words, this is a cheap and high-quality product that must be given a five-star rating

  • Good mattress
Size: Queen Style: 12 Inch
I recently purchased a firm queen-size mattress, and it has exceeded my expectations in every way. From the moment I laid down on it, I could feel the perfect balance of support and comfort. The firmness level is exactly what I was looking for—sturdy enough to provide excellent spinal alignment while still having a slight cushioning effect that prevents any pressure points. Whether sleeping on my back or side, I wake up feeling refreshed and without the stiffness I used to experience with my old mattress. ... 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

  • Great mattress!
Size: Queen Style: 12 Inch
Really good mattress! No smell or odor! It’s super comfy and big. I would says its a good medium between soft and hard. I got the correct size and it arrived a day early. Overall, if you are anything like me and overthink everything I would recommend getting this mattress.

  • 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.
