    Loved it so much, bought a second one

    We struggled to find a bed we liked and tried some online beds, most costing more. We sent one back because it caused hip pain and had to wait because of production delays. We went to get a temporary mattress that would eventual go in the guest room to use until then. We settled on the Harmony Lux Carbon Plush. We slept on it and immediately noticed more comfort and better sleep than we have had in years. The online mattress came, we moved this to the guest room and slept on the high end mattress. Two days later we moved the Beautyrest back in our room, sent the online one back, and purchased an identical second Beautyrest for the guest room. Couldn’t be more pleased with the purchase. We did get an adjustable bed frame that works great on this mattress. I was concerned because of the thickness, but the massage feature, etc all work great in conjunction with this mattress


    Harmony Lux Carbon Classic Top PLUSH - Initial Rev

    I received my Harmony Lux Carbon PLUSH Classic Top mattress two days ago. Very comfortable on my back and so far so good. Unable to comment about long term wear at this time. I purchased this to replace a previous Harmony Lux Carbon Medium Firm mattress purchased at another retailer as the medium firmness was too extremely firm for me. I'm hoping that the initial comfort of this mattress will remain the same for years to come without any sagging or indentation issues.


    best sleep

    I am very glad I purchased this for my daughter. She is 16 and loves it. She says she sleeps so cool also that the mattress is comfortable. It really is holding up . She has had it for 6 months now


    Good Mattress for adjustable bedframe

    I was excited to replace my current pillow top style mattress with this Harmony Lux Carbon Plush model. It came from online, so I was not able to lay on it prior to getting it. This mattress is not quite as soft as I thought it would be considering the word plush is in the name. On a scale of 1-10 for softness I give it a solid 6. When you lay down you don’t sink in very much, which is how I can tell if a mattress is soft or not. This is definitely not as soft as a pillow top style mattress, so if you are looking for something more soft this may not be the right fit for you. At first look you can just tell this is a high-quality mattress. The material used to construct it is some of the nicest material I have ever seen on a mattress. The material has a great thickness to it. The top part is a cushioned white material. The sides are a darker blackish color. This is a pocket coil style that has pressure relieving foam in it. I decided to not put any fitted sheet on it so I could lay right on the material and see if I noticed any difference at night. I am a larger body type who sleeps on my back. I also have an adjustable bed frame and this mattress bends nicely when I raise the head and feet just a bit. If you are wondering how this mattress will work if you have an adjustable base, I can tell you it will work wonderfully! This was one reason I chose a plush model is so I knew it would bend easier. Another feature this mattress has is a cooling technology. Being a hot sleeper, I was excited about this feature. The delivery person explained to me that the blue lines in the mattress are the cooling technology that ripples through the mattress. (See photo) I will say that when you put your hand on the mattress you can sort of feel the cooling layer. This was another reason I kept the fitted sheet off as I wanted to know how it would work. I can honestly say I did notice a little bit of difference on it feeling cooler in the night. The sides of this mattress hold up very well if you are sitting on the edge to put clothes or shoes on. The stitching at the sides is very well made. There are also very thick straps on the sides for when you need to turn the mattress or carry it. I would not be afraid that they will rip off as they are very sturdy. After about almost 2 months of using this mattress I will say it is working as I expected it to. I expect it will be a mattress I have for a long time coming. The only reason for the 4 star rating is I wish it were a little softer.


    Super soft

    After sleeping on it for sometime, I can say that it is really soft. It's almost like a pillowtop, that's what my previous mattress was. When it first came, there was no smell to it, some mattresses have a strong odor at first. The matress does not make me sweat at night, which is nice. I use plain cotton sheets on it. When I was choosing a mattress i didnt want to get a firm one, instead I went with a medium one. It is really soft though, which I like, but overall I think it's probably on a softer side rather then a medium. There is really nothing negative to say about it. I love my new mattress and it serves its purpose well.
