  • Great Support – Worth the Heavy Lifting
Size: Queen Style: 12 Inch
Picked up the 12-inch queen size at a great price, and it’s definitely worth it! Heads up, though – the box is super heavy, so you’ll need some muscle to get it in place. Once opened, I could tell the materials and build are high quality. I noticed it has denser pull points in the middle, probably for added support around the waist area, which is awesome. I marked it for myself so I know exactly where to align when I sleep.  I’m around 200 lbs and usually toss and turn a lot, but since using this mattress, that’s pretty much stopped. I sleep on my side and haven’t felt any soreness or discomfort, which is new for me! My back feels supported and aligned, and the mattress feels even all the way through. Love that it has handles on the side to help move it too – makes handling a lot easier. I came from a medium-firm plush mattress that was always too hot and lacked support. This one really does the job right. Highly recommend for the price! ... show more

  • Great finish and comfort at a bargain price
Very happy with our purchase. No odors we could detect (and we're picky about that), and even though it says to allow 72 hours to fully expand, within 15 minutes we could tell it was plenty comfortable for the occasional use we expect to use it for, but no reason it wouldn't be fine for full-time use. I don't see how the folks with the poor reviews got the same mattress, unless they had it upside down; the memory foam and padding are only on the top. Placed directly on a cheap metal frame (the kind with the wires going across), it was perfectly flat, stable, and comfortable. And as a bonus, it has handles on the sides to move it around. ... show more

  • Comfy, No Smell, Great for the $$
Size: Queen Style: 12 Inch
My husband thought there was no way an entire queen mattress was in that box. But once we unrolled it, it inflated quickly. We let it set overnight, and it is super comfy. No wierd smell. I will say I think the edges could use more reinforcement as it gives a lot of you sit on the side of the bed. But overall, great quality for the price. Very functional, clean, and comfy. Slept like a baby! ... show more

  • My back says, “thank you”
Size: King Style: 14 Inch Firm
Heavy mattress. Took 2 people to carry upstairs. When compressing the mattress they only roll it up lengthwise, no folding. So the box was 76” long. Easy to unroll the first layer of plastic. Started expanding quickly. Then cut open the inside layer of plastic with the cutting tool they gave in the ziploc bag. No smell to the mattress. Inflates quick enough to sleep on first night. Actually expanded to 14”. Soft yet firm. I was worried about buying something like this online, but the gamble payed off. Back aches are no more. This king size 14” firm mattress is pretty perfect. Don't hesitate to buy. Definitely worth the price. ... show more

  • So plush!
Size: Queen Style: 14 Inch
Wow! Just wow! So first off right out of the box and plastic wrap the bed was already at 12 inches out of 14 inches high! That’s incredible! I expected it to be at like 9 or 10 straight out of the box! It was at the full 14 about 48 hours later! So don’t sleep on it for a couple days to get the full effect! Initial impression looks expensive, has handles to lift and pick up, very plush looking! Very impressed all around. Now for the comfort! Oh my gosh! I honestly I can’t believe it for the price! Very comfortable, very well made. Not too soft, not too firm, it’s honestly a perfect mixture. Quality of this mattress did not disappoint! ... show more

  • Best Sleep Ever!
Size: King Style: 12 Inch
I love this King Size Memory Gel Foam Mattress! It’s the perfect balance of soft and firm—providing great support while keeping me cool at night. The gel foam adapts to my body, and I’ve noticed less back pain since using it. Motion isolation is excellent, too. Overall, it’s an amazing mattress for the price and has significantly improved my sleep quality. Highly recommend! ... show more

  • Comfortable but too much sinking
Size: King Style: 12 Inch
The mattress was okay overall. It inflated quickly and didn’t have any unpleasant odors, which was great. The box was heavy but manageable. Sleeping on it was comfortable at first, but the major issue is the sinking. Both my partner and I found ourselves sinking almost halfway into the mattress, which made it less supportive than we’d hoped. While the price is fair for what you get, the sinking was a dealbreaker for us. If you prefer a firmer mattress or need more support, this might not be the best option. ... show more

  • Great mattress
Size: Queen Style: 12 Inch
I was a bit sceptical about the quality of the mattress. Price was too good to be true. It got delivered and was vaccum packed. We opened it and it expended fast. Took a day to fully rises up. My son said that the mattress is very comfortable and with no issues. Glad I bought it for him.
