Style: 14 Inch
Overall, this mattress provides a very satisfying experience and feels well worth the price after using it for some time. The 14-inch thickness offers solid support, and the zoned design provides noticeable support for the shoulders, waist, and hips, helping to prevent back pain after sleeping. The firmness is medium on the softer side, offering a comfortable contouring feel without making you sink in too much, making it suitable for both side and back sleepers. The cooling effect is also quite noticeable, keeping you from feeling too hot during summer nights, and the overall breathability is good. The mattress comes vacuum-packed; there may be some wrinkles when first opened, but it expands back to its full thickness in about 3 minutes. It is also very quiet when turning over, causing minimal disturbance to a partner. There is a slight odor upon unboxing, but it dissipates after one or two days of ventilation. Overall, this is a high-value mattress that balances comfort, support, and affordability.

The Sweetnight CoolNest 14” Queen Mattress has been a really comfortable upgrade. The cooling memory foam does a great job regulating temperature—I don’t wake up feeling overheated anymore, which was a big issue with my previous mattress. The 5-zone ergonomic support provides a nice balance of comfort and support, especially for my back and shoulders. It feels medium-firm, which works well whether I’m sleeping on my side or back. I also appreciate that it’s CertiPUR-US certified, so there’s no strong chemical smell and it feels safe to use. Setup was easy—just unbox and let it expand. Overall, it’s a comfortable, supportive, and cooling mattress at a great price point. Highly recommend for anyone looking for better sleep without breaking the bank!

In a word- Yes. It’s very comfortable- firm yet supple without being hard, while supportive in a slightly form-fitting way. The mattress was delivered within a few days. It’s easy to unbox and set up- the mattress expands very quickly. There was no odor. Be careful opening the shipping box and cutting plastic wrap of mattress. From the first night, I noticed the difference it’s very comfortable, provides great support, and doesn’t sink. The size is perfect,I’ve been sleeping much better since I got it. It doesn’t get hot and adapts very well to the body. if you’re looking for something comfortable, affordable, It also offers great value for the price compared to other mattresses on the market.I definitely recommend this mattress to anyone looking for comfort, quality, and affordability.

We’re a couple and just got this mattress, and it was ready much faster than expected—pretty much fully expanded and usable after about a day, which was a nice surprise. After the first night, we’re already really impressed. The cooling is noticeable right away—it doesn’t trap heat like our old mattress, and we both slept more comfortably without waking up sweaty. The support feels well-balanced too, not too soft or too firm. I usually have some lower back discomfort, and even after one night I could feel a difference—it felt more aligned and less pressure in the morning. It’s also very easy to set up and use. Taking it out of the box was straightforward, and we didn’t have to wait days for it to be ready, which made the whole experience much smoother. Motion isolation works well too. One of us moves a lot during the night, but the other barely notices. Even our cat jumping on and off the bed didn’t really disturb our sleep. Overall, it already feels like a big upgrade after just one night. Comfortable, supportive, cool, and super convenient—very happy with it so far.

It was easy to set up and expanded pretty quickly after opening. The queen size fits my bed frame well. The mattress feels comfortable overall, with a nice balance between softness and support. It’s soft enough to feel relaxing when lying down, but still firm enough that I don’t feel like I’m sinking in too much. I’ve been sleeping on my side and back without any discomfort. I also like the height and how it looks once the bed is made. It gives the bed a cleaner and more finished look compared to my old mattress. So far it has been a good upgrade for everyday sleep. For the price, I think it’s a solid option and feels worth it.

Bought the 14 inch mattress and still I haven’t slept on it. But when I tested it’s soft and feels supported. As a side sleeper suffers from back pain frequently, i look for comfort and support without going for a high end brand which costs me my kidneys. After a lengthy research I went for this mattress. I will update my opinion on that aspect after sleeping on it for a few weeks. I let it get decompressed expecting it to expand fully for one week. It’s rather quick process yet I wanted to go for an extended period of time expecting better results. But after a week I still feel like one side is quite short and that’s an unnoticeable difference yet visible if you look closely. And the cover is still sightly loose on the right half of the mattress. On two sides I can feel slight lumps when I run my hand on sides. But this doesn’t impact the usage. Mine is a king size 14 inch and the expansion did fit the mattress to the bed and the gaps are very small. So the fit is 97%. There is no weird smell and I didn’t notice any smell on it when tested. It’s quite cool. For a strong person the compressed mattress won’t be a big deal to move . But for me (5’3” 155lbs with weak spine) needed help of another person to move it to upstair bedroom.
