  • Replaced a $6,000 mattress
Style: 12 Inch Size: King
So, about 3 years ago my wife and I were suckered into buying a $6,000 mattress at a retail mattress store. "We are going to spend a 3rd of our life on this thing - so it needs to be a really good one" was our thinking. Well, it *was* a really good mattress - it was just too soft. And after 3 years of use, it was even softer.... starting about 6 months ago, both of us were waking up with significant back pain every day. Then we went on vacation for a couple weeks and I noticed that both of our back pain went away. "It's our mattress!" I thought. I turned to Amazon and found this thing... and at this price - I thought, "I'm gonna try it! - what do I have to lose?" Well, that was about 3 weeks ago.... and I am here to tell you, that this is NOT as nice as the $6,000 mattress - BUT IT IS PRETTY DANG NICE. And, most importantly, our back pain is gone. My wife says "there is no way this thing will last at that price" - and I say "WHO CARES!" if I have to buy a new one every year, it's still way cheaper than most mattresses! And I am pretty sure this will last longer than a year. It *is* well made and very comfortable. We did not wait the recommended 24 hours or 36 hours or whatever, we opened it and waited about an hour. Put the bedding on.... and hit the sack! We've been sleeping great ever since. Really. It's a great mattress, don't let the low cost fool you. IMPORTANT NOTE: MY WIFE AND I ARE BOTH 165 LBS OR LESS. So... if you are "big" - your mileage may vary. ... show more

  • Didn't expand the whole way. Lacks foam.
Style: 12 Inch Size: Full
Update: The seller was quick to respond to me. They told me to measure the height from the middle of the bed rather than the edges. I haven't been able to do that because my bed been set up and covered with a padded mattress protector since I got it. They offered to send me a foam topper if I still had an issue. I bought this mattress because I had a memory foam mattress previously that was just too hot and firm for me. This mattress sleeps much cooler! I don't wake up in a sweat. The springs are good and provide nice support. I used to wake up with stiff or painful hips/lower back. That is significantly better too. I didn't think I would recommend this bed at all. But it's actually quite nice. Especially for the price. Previous review: I got this product 3.5 days ago. I opened the package within 2 hrs of its delivery. I allowed 72 hrs for it to expand. I ordered the 12in mattress so it would have more cushion and be less firm than the 10 in. It expanded to 11 inches at most. The information included in the package says the product may very up to 1.5inches, which seems like alot. The springs go all the way to the top. The picture led me to believe that the springs would stop at the first seam and would have a good layer foam on top of that. The foam is very thin. This is essentially a spring mattress. Not a hybrid mattress. I have yet to sleep on it, since I was letting it expand, but it feels very firm and lacks padding to soften the spring pressure. I will be contacting the seller as soon as I figure out how. I will update after I sleep on it and get more information from the seller. ... show more

  • I LOVE IT
Style: 12 Inch Size: King
I let it expand fully for 2-3 days, it went to the full 12 inches. Careful not to poke a hole when opening the packaging. It’s super soft and firm at the same time. No back problems or anything other than a great nights sleep and beautiful aesthetic for my room! No complaints AT ALL. A must buy. Would purchase again. ... show more

  • Great mattress for the price
Style: 10 Inch Size: King
The mattress is great quality. It’s a firmer mattress that’s still soft. It took a couple days for it to fully plump up out of the box but it’s a wonderful mattress for the price

  • It is VERY HEAVY! But VERY WORTH IT
Style: 12 Inch Size: King
I set up the new mattress today and yes it was super heavy for me (70lbs) but I followed all directions and it rises as soon as it is out of the wrapper! I do not think I’m getting out of bed again! It’s like butter! Soft and so easy! I’m so comfortable on this mattress I almost cried! Sleeping has never been this cozy! ... show more

  • Not bad so far
Style: 12 Inch Size: California King
I was very hesitant due to reviews. However, none of the reviews match this mattress. I have had this mattress now for 6 months. No sagging, no discomfort, no fowl smells, nothing dangerous that i can see, feel, or smell. I do have a very thick mattress cover over. I do this for all my beds. I did let it air out and rise for 4 days to make sure i gave enough time. I was in no rush as i was waiting for my box springs. ... show more

  • Comfortable and Affordable
Style: 12 Inch Size: Queen
Have been using this mattress for a month now and I love it! It was a great price point for a hybrid mattress. Super comfortable and my lower back pain has been gone. No sagging so far which I was worried about since I am a larger body person. Definitely recommend!

  • Tested for a month
Style: 12 Inch Size: California King
This mattress is fantastic. We didn’t enjoy the set up of leaving it open and not used for 48 hours, this was not ideal…but completely worth the wait! No pain or discomfort when using this mattress even after a month. Also with 2 grown adults and 2 80+ lb dogs sleeping nightly, there are no dips or craters that we sleep in. Definitely worth the money! ... show more
