Zinus 12 Inch Full Cooling Essential Memory Foam Mattress [NewVersion], Fiberglass Free, Medium Feel, Breathable Cooling Layers, Certified Safe Materials

I bought the Zinus 10 Inch Twin Cooling Essential Memory Foam Mattress for my kids after they outgrew their toddler beds, and it’s been a great upgrade. They found it comfortable right away—soft but still supportive—and they’re actually excited to go to bed now. I also like that it doesn’t trap heat, so they stay comfortable through the night. Setup was quick and easy, and the mattress expanded fully within a day. For the price, it feels like really good quality. Cons: edges are a bit soft, and it may be too plush if you prefer a firmer mattress. Overall: a great, affordable option for parents transitioning kids out of toddler beds!

I bought this mattress expecting a medium feel, but it is definitely more on the firm side. Honestly that worked out perfectly for me because I was actually looking for something firmer. At first it felt a bit hard, but after a few nights I got used to it and now it feels very comfortable. I sleep well, fall asleep quickly, and wake up feeling rested. It gives me the support I was hoping for. The quality is also really good for the price, and I was happy that there was no strong smell when I opened it. I know comfort can be different for everyone, especially when it comes to back support, but for me this mattress has been a great choice. I am really happy with it. I am a 175lbs man standing on it!

This mattress is really good, very comfortable, easy to set up, great looking, it stays cool, so no night overheating,make zero noise, fits perfectly, the memory foam is just what I needed for my back pain, haven't sleep this well in quite sometime, has a very good price tag and is super high quality, recommended to anybody dealing with pain, and desperately needing a durable mattress that can help easy up any type of pain

I ordered the Zinus 12-inch King Cooling Comfort Hybrid, and the mattress itself is amazing. It feels high-quality, supportive, and perfectly balanced for anyone who doesn’t like a bed that’s too soft or too firm. It arrived quickly, expanded well, and the comfort exceeded my expectations. My only complaint—and the reason for the 4-star rating—is the delivery experience. I clearly requested that the mattress be placed at the back of my house and leaned against the wall because I’m home with a 4-month-old baby and can’t move something this heavy on my own. I also didn’t want it sitting out front where someone could take it. Despite the instructions, the drivers ignored them and left the large box by the front door on a rainy day. There were two men, and from my camera I could see they had read the instructions and still chose not to follow them. The mattress itself is fantastic, but I really wish the delivery service had been more considerate.

This is my second Zinus. And that's not saying anything bad. About 5 years ago I got the 10inch standard firm green tea queen mattress. Love it. Great support. After about 3 years it started to break down where people lay the most at finally this week it was time to replace it. I went with this 10 in cooling queen this time. So far love it as always easy to unpack and set up. Super comfortable. Seems like it will be cooler sleeping then the last one. For the price I'm sticking with Zinus! To get 5 really comfortable years out of a mattress in this price point is insane. And most will probably get more then 5 as we're hard on mattress here. All around comfortable quality products that are a fantastic value for money!

It’s a firm mattress but I knew that going into it and when paired with a memory foam topper it’s perfect for me. I’m a plus sized girlie and this brand came highly recommended. Wait the full 72 hours before you judge its feel. Was slight difficult to unpack alone. My back pain has greatly improved and it doesn’t feel “springy” or cheap

High quality So smooth Feels stiff to sleep on, super sore the next morning if you’re over 30 🤭 you’ll need to invite all your kids to jump on it to break it in. And add a foam/ puffy mattress topper Value for money

Good mattress

Lo ameee, en un principio estaba preocupada por las reseñas que decían algo como “No se infló de las esquinas” “mide menos de lo que indica” o personas que comentaban que es muuuy firme y otros que demasiado suave. En lo personal, es perfecto para mi. Es suave, pero al mismo tiempo es firme. Y por el precio, estuvo más que perfecto. No puedo creer que un colchón pueda llegar a verse muy hermoso kslslsls

Vino muy aguado es de 8 pulgadas de grosor,no me gustó,tuve uno hace tiempo de 6 pulgadas de grosor y me encantó está muy bueno el colchón pero esta vez no me agrado, gracias

Superó mis expectativas

Very nice and spongey but not soft. It feels very sturdy unlike others I’ve bought.
