This mattress is truly amazing! The 14-inch firmness is perfect — supportive but still super comfortable. The memory foam feels high quality, and I noticed the difference in my sleep right away. No more waking up sore or tossing around all night. It’s thick, sturdy, and gives a luxurious feel without the luxury price. If you’re looking for a firm, comfortable, and reliable king-size mattress, this one is definitely worth it. I absolutely love it!

The option I chose was queen size, 14-inch firm. Honestly, I doubted this mattress at first because it is memory foam and the price was much cheaper than well-known brands. I wasn’t sure if it would be worth it, but I wanted to try. When it arrived, it was packed in a box, and I really wondered if it could actually become a 14-inch queen mattress. I left it overnight in the living room, and it expanded into a full-size mattress just like it should. The firmness is intact even though it is memory foam. I usually have some ache in my waist and back, so firmness is important. I have been using it for four nights, and I haven’t felt any discomfort. I’ve been able to sleep through the night without interruptions, which was better than I expected. The height is also as expected, and I could make a very high bed with it. One thing I was glad about is that there was no factory smell. Many products or clothes that come tightly packed have a vinegar-like smell, but this mattress did not. Because of that, I was able to start using it right away without worrying about washing or airing out the cover. The cover itself has a nice color and design, but I don’t want to damage it, so I’m using a mattress cover and sheets on top.

This 14inch king memory foam mattress has completely transformed my sleep experience! The cooling knit fabric cover is soft and breathable, keeping me cool through out the night. The copper-infused memory foam provides excellent support while relieving pressure points. I love how firm it feels, offering the right amount of support for my back. It's also great knowing the mattress is CertiPUR-US certified and made in USA. The fiberglass-free design gives me piece of mind. It arrived in a compact box and setting it up was easy. It expanded quickly and was ready to use in few hours. I have been sleeping better and waking up more refreshed. Overall, it's an affordable, high-quality mattress!

I have a sleep tracking app. My average sleep score was in the '30s and '40s on a new med-firm hybrid. Firm beds never seemed firm enough. Since this mattress arrived, my sleep score has been in the '80s. Well made, beautiful, feels ULTRA FIRM!! NO JOKE! I'm convinced I could set a glass of wine on this mattress and go to bed and it would still be standing in the morning. I even added my old 3-in egg carton shaped foam topper and it is perfect. If you don't want ultra firm don't get this mattress! I absolutely love it.

I scouted so many mattresses before settling on this one so I hate to say I'm a bit disappointed. It's by no fault of the mattress itself but my body composition. I had reservations about this mattress being too firm for me and turns out I was right. I wanted to give it a fair shot so I waited to review but it's only gotten worse. I'm someone who works out 7 days a week so rest and recuperation is incredibly important to me. I also have a few lingering injuries and this mattress hasn't helped. As time has gone on, it's gotten a bit worse. It's strange to me because I feel the enveloping support this mattress provides. Even through it's firmness, there's a soft body wrapping quality that this mattress possess. It's comforting but I never feel rested. I didn't want to hold any of this against the mattress because I'm chalking it up to my own miscalculation. I'm going to give it more time because I have seen some reviews says the same thing. I hope it gets better because as is, I'm feeling more pain the more nights I'm on this mattress.

Pretty good mattress for price. Expanded really quickly and no "new mattress smell". Quality seems great. It is extra extra firm its a very solid mattress so i wasn't sure about it. But gave it a couple weeks and have a softer mattress cover/pad on it and i love it. Me and my husband are both 5'10 and it is holding up well. No noise or movement felt when other move. Great size and height. If your on the fence buy it. My sleep quality has improved.

I purchased the 14 inch king size mattress. It arrived intact and at only 85lbs, it was easily maneuverable on to my existing box springs. Once opened, the mattress became fully inflated within a few hours. Absolutely zero chemical smell. The mattress is sold as a firm mattress and it truly is firm. Extremely comfortable, not hot and standard king sheets fit perfectly. The side is firm enough to support my weight (225lbs) when sitting on the edge prior to rising in the morning. Extremely pleased with the mattress, great value for the quality of materials and super happy with the comfort.
