I've had this mattress for a year, and it's still very comfortable. I sleep well on it. I prefer a slightly firm bed, and this one is perfectly firm for me. I enjoy it, and as someone who is 5'7", I can sleep on it comfortably. There is no smell at all. The size is good for a twin mattress, just as expected. It was also very easy to set up. As for heat, it doesn't make you hot; that depends on your blankets. It's been a great purchase, and I am very satisfied. Read more

I’ve gone through many so-called “firm” mattresses that ended up being soft and saggy. This one delivers—no sinking, no hammock-like sag. Just strong, even support from edge to edge. Within a few days, I could feel my midsection properly supported, and my back pain noticeably improved and I feel energized in the morning. Pros: * It’s exactly what a firm mattress should be—flat, stable, and supportive. * Top-notch quality: Made in the USA, and it shows. The materials feel solid and built to last. * Hybrid coils (a rare find): They add durability and support. * No sag in the center: My spine stays aligned all night. I’m definitely getting more for the rest of the house. I’d give it ten stars if I could. Awesome brand, fantastic product. Highly recommend if you’re after a truly FIRM mattress. Read more

This bed is excellent. Bought the TWIN 9”. No surprises and exactly what you would want if purchasing a mattress for the first time on Amazon-without being able to feel it for yourself before buying. This is just the firm you would want-if you don’t want a soft mushy mattress. I stay very cool lying on this mattress(using only cotton for mattress cover and sheets). Just the right height. I had a great sleep the first night-and continue to still. This is a mattress you will look forward to sleeping and chilling on every night. After I recieved it vacuum packaged and rolled up in box left by UPS, I let it unravel on top of my boxspring and settle for almost 24 hours before I laid on it, just to follow the instructions properly. Smells brand new, but no offensive odors or anything. I was excited to sleep on it. Beautiful mattress, and you can turn it clockwise or counterclockwise monthly to break in the foot & head end evenly if you want. Worth it, would buy again-and would direct anyone else I know to buy this one. Superior value for a really great price!!! Read more

I've had this bed for a little more than a year, and honestly I like it, but it's firm. I weigh about 160 and after a year, it's still firm. There is no indentation nor does it sag anywhere. There might have been a smell in the beginning, I don't remember. What I do remember is that if there was a smell it was not strong at all. Overall, it's a good quality inexpensive mattress, but it's firm. Read more
