- Comfort Foam For A Clean Sleep EnvironmentWith its CertiPUR-US certified comfort foam, this hybrid mattress effectively eliminates unwanted odors, regulating temperature, and ensuring a dry and clean sleeping environment. Furthermore, the hybrid design allows for edge support on both sides of the mattress to prevent any potential slipping when sitting on the edge of the bed.

When I opened the box, it gave me a pleasant surprise. The packaging was very good. The thickness of this mattress is just right. It looks very good on my pink bed frame. When I come home from get off work and lie on it, I feel very comfortable. The tiredness of the day disappears. It is not a very soft mattress. It is very supportive and the price is very affordable. My children also like to lie on it and play. It is worth buying.

I’m really happy with this mattress. It arrived fast and was easy to set up. After opening the box, it puffed up fully within a few seconds and didn’t have a strong smell. The mattress feels not too soft, not too hard. I sleep on both my back and side, and it’s been very comfortable. I also like that I don’t feel much movement when my partner turns over at night. It looks nice, feels supportive, and I’ve been sleeping really well since I got it. For the price, this is a great deal. I’d definitely recommend it to anyone looking for a good, affordable mattress.

Our daughter moved back in with us after a divorce and brought a bed with her. She used it for about a year before stating that it was hurting her back. One look and we were stunned she used it at all. The mattress was beyond its days. I went looking for one that was affordable for her, since her income is limited and found this one. Based on the reviews, we decided to go for it. It arrived fairly quickly and although heavy, it was not so heavy that I couldn't carry the package myself (I'm a female, 54 years old, 5'2", 110lbs...just for reference). She was working a night shift and my husband works swing. I admit to being an "I'll do it" kind of person and since this needed time to sit, I did just that. I packed it downstairs myself after I got home from work and set it up for her so it would be ready when she got off work. Now, be aware, this is vacuum sealed, so when opening you want to be very cautious. I took my time removing the plastic and tape so that it would unfold slowly rather than bust open and cause damage or injury to anything and anyone around it. Success! I was able to slowly unravel it and place it on top of her box spring without anything or anyone getting broken. After she got home, she made her bed and when she woke up the next morning, she marveled at how comfortable it was. Granted, she could feel the springs in her last mattress so almost anything would be better, but she was really impressed with the quality given the low price. It's firm yet not so firm that it feels like she is sleeping on boards. She says she doesn't toss and turn as much and she doesn't feel the mattress move when she does. She's had it for close to a month now and she is sleeping well and feeling rested. She's very happy with it. We'd both recommend.

Great for the price! I got it for my daughter who just moved out from school dorms. It was super easy to unwrap, and the mattress expanded right away. It probably took around 3-4 hours to fully expand and is super comfortable. It is on the softer side but offers great support and is of great quality, especially considering it’s a box mattress. It came sealed in a small box, super easy to move into a new house.

Why did you pick this product vs others?: great value! I was a bit unsure at first, but this spring mattress turned out to be much better than I expected. It provides great support — firm but not too hard — and I’ve been sleeping really well on it. The materials feel solid, and it holds its shape nicely. No weird smells, and it didn’t take long to fully expand. For the price, I think it’s an excellent deal. Highly recommended if you’re looking for something simple but reliable.

I’ve been using this mattress for some time now and I have to say it’s been a great experience. It gives just the right mix of comfort and support. I feel my back is well supported, but at the same time it’s soft and cozy to sleep on. One thing I really noticed is how comfortable it stays through the night. It never feels too hot and always feels relaxing when I lie down. I also like that I don’t get disturbed when moving around in my sleep. Overall, it feels strong, comfortable, and very restful. I wake up without stiffness and feel fresh in the morning. I’d definitely recommend it to anyone looking for a good, reliable mattress that makes sleep much better.

I bought the 8 inch mattress for my almost 4 year old and it’s super comfortable and perfect for her size. I have an all foam mattress that I’ve had for about 4 years and I wish I would have bought a hybrid spring mattress like this. It’s the perfect height for her bed frame. It expanded quickly and had no odor at all. We ripped open the plastic together and my daughter was excited to watch it expand. The corners do sink in and make it difficult to sit on the edge, 2/4 corners are visibly sunk in. Overall though, this is is a great bed for a toddler/ growing child and I’ve slept in it and can attest that it is very supportive and comfortable. I was waiting to get her a new bed until I could find something affordable and comfortable. This bed would be something I would pick out in store but I’m grateful that I was able to just buy it online and have it shipped to me. Definitely would recommend this for all ages. It’s not too firm or too soft, it’s not bouncy but supportive. I may order a queen size to replace my current mattress bc the price is reasonable.
