Simply wonderful mattress, luxurious fabric and no odor. The mattress is firm and soft in the right measure. It keeps the spine aligned and does not leave the body sore. It was the first time I had a foam mattress and I was surprised because I found it better than the spring mattresses I had used before. I really recommend buying it, it is worth every penny of the investment.

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 have been suffering from some bulging disk issues, and the pain has been extreme while sleeping on my current older memory foam bed. I was looking for something not so expensive and within a price range. I relied on the reviews to make my purchase, and I am happy that I did. After waiting 12 hours for full expansion, I then went to bed with great anticipation. Once asleep, I did not experience any issues. I did not wake up in the middle of the night with pain and sleep through the entire night. Once I awoke, I was able to get out of bed easily with no pain. I have been sleeping on it for a week now and I am so satisfied with the comfort and firmness. It has just the right amount. If you are looking for an inexpensive mattress, I would encourage you to purchase one of these. I purchased 2 twins xls for a calfornia king

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.

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.

Only been opened for one hour and it’s already a night and day difference from our old pillow top mattress. So much support provided from an economically priced mattress. Sleeps great. Sleeps cool to me. Have noticed no smells. Feels and works with high quality.
