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.

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!

My husband absolutely loves this mattress. He said it's very comfortable. I've purchased multiple. A little bit of dome damage + physical exertion = cognitively bankrupt! The seller's customer service is awesome! They were and are still so patient and kind. I'm still working with them to get some things sorted re one of the multi purchases but they have provided the best service from the very onset. I messed up and bought not only a Queen size for my King bed but also the copper infused when I have an MCAS & Autonomic Neuropathy caused metal allergy which makes copper the worst reaction because it's such a high energy conductor. It literally spikes my pulse up toward 300 bpm. Neurologist stuttering...you've got a serious problem when they caught it on monitor in hospital. Erm, ya think! Now that I'm on daily steroids it has toned down so I was able to lie on it very briefly to feel why he liked it so much. I have to admit that I did not sleep on it. I wanted to return bit it was opened. The box clearly stated 14" copper mattress. So people, read the boxes before you open!! Screw up #2 re this purchase. I was not on my game cognitively. If I were, I would have not opened it and just refused the package. This one was eager to expand. I've never had anything vacuum sealed expand so aggressively. It came wrapped in very thick plastic and had 3 strips of tape on it. I cut the tape and it immediately began expanding inside of the plastic while still rolled up. Since the return policy is that it must be boxed the seller gave me a small refund. I'd have to have paid a large freight company more than what I paid for the mattress to wrap and ship it fully expanded. That's not happening. It expanded fully within minutes. Seriously, came out like a Jack in the Box. Hubby slept on it that night. Unlike charcoal, the copper has no odor. With the hubby's utter disappointment, I gave it away.

I haven’t slept on this yet, but I’m so ready too! Super easy to unbox. Heavy (as expected), fluffed up fast once unpackaged. I laid on it to test it out and instantly loved it! Thinking about trying it out a few nights and then may replace my kids mattresses with this as well! The size matched the description and its great quality!

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’ve had this bed for a week now, figured I’d wait to review. This thing is perfect. Very firm just how my back likes it. I have zero pain, fall asleep super fast and I don’t wake up aching all over. I do not regret this purchase at all and I was very skeptical about buying a “mattress in a box” but this was worth it. Definitely give it a buy if you suffer from chronic back pain.

Good inexpensive mattress replacement. Very firm and supportive. Switching to memory foam from a pillow top was a bit of an adjustment, but I'm getting good sleep and no back issues.
