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 had this sitting in my cart for months! I went back and forth and was nervous to buy a bed off Amazon for fear of it just not working. This gets a 10/10 for me! First time I woke up without back pain in months. I had the best sleep! This is very affordable and I feel like I spent thousands on the bed. I chose the 14” Firm King. I wasn’t sure how firm it would be as I saw mixed reviews. It is very firm, but exactly what I wanted. I am pleasantly surprised of the quality. It’s affordable, great back support, and I slept like a baby!

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.

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.

The most comfortable sleep I have had in years. I didn’t realize how badly I needed a new mattress until I slept on this one! It is firm enough yet soft enough for comfort. I love how the memory foam contours the body and provides the right amount of support. It eases my sciatica pain with the right amount of resistance. There are so many mattresses on the market, it is hard to select the right one. Buying this online without testing it first was daring but I made the right decision. I have gone to stores and tried mattresses and ended up with a bad one because those few test moments in the store isn’t enough to really know how the mattress will hold up. Sleeping on it is the only true test. After sleeping on this mattress, I am pleased with my purchase. The mattress appears durable and the price is amazing for the quality you get.

Super comfy, amazing value for the price. We previously had a more well-known big brand that cost twice as much, and after a week of using this have no intentions of going back. Cool to the touch, looks good, and the cover can be zipped off to either clean or get to the mattress material for whatever reason. Comes in a manageable box size and a cutting tool to release the mattress from the packaging. We got the 12 inch and it recommends letting it expand for 12-24 hours after opening. Definitely recommend!
