I've been using this mattress for about a week now, and I'm really impressed. It's medium firm. The top layer material feels really cool and very comfortable as described. It can keepcoolingwhole night. It gently contours to your body while still providing the right amount of support to your body because of the great design. Overall, it's a great mattress, and I really like this one!
This mattress is super comfortable and keeps me cool all night. No more waking up sweaty!
This mattress is hands down the best I’ve ever slept on. It is truly acooling mattress. I look forward to sleep time.
This mattress is exactly what I needed. The cooling gel memory foam really helps regulate temperature so I don't wake up hot anymore. It's medium firm with great support that eases pressure on my back and hips. It's super comfy and helps me get a good night's sleep. Highly recommend!
This mattress is amazing! It's the perfect balance of soft and supportive. The cooling gel really helps – I don't wake up hot anymore. The 5-zone support makes a big difference for my back, and I sleep through the night pain-free. Setup was easy, and it feels like a high-quality mattress. Definitely worth it!
The Sweetnight CoolNest mattress is honestly one of the best purchases I've made. It's supportive without being too hard, and the cooling gel really makes a difference—I no longer wake up sweating. The motion isolation is great too. My partner and I both sleep better and feel more rested every morning.
We received pur matress, came as described, followed the instructions with the matress and had no issues, very good quality matress and stays cool with cotton sheets. Only one issue that isnt an issue, i wish the matress had handlesnto help move it once itbis raised.
I couldn't be happier. It's incredibly comfortable and provides the perfect amount of support for a good night's sleep. The quality is fantastic, and I love the way it contours to my body. Definitely worth the investment! Highly recommend!
This mattress is amazing. It's firm yet comfortable! The edges aren't very firm, but I still recommend it. It's definitely worth it. The delivery was fast, the price was fair, and the quality is just as good as I expected. I was looking for a medium-firm mattress, and this one gives just the right amount of firmness with a memory gel layer on top.
I bought this queen-size mattress for my parents and we're really happy with it. It's thick, well-made, and very breathable. The fabric feels soft and comfortable, and the color is practical since it doesn't show dirt easily. Definitely great value for the price!
I have used this cool foam mattress for a month and I love it. As shown in the pic it is very thick, about 14 inch, very soft and comfortable. The most amazing part is that it has cooling memory foam. It keep me cool at night time so I can sleep very well. The texture feels very comfortable as well and I love the touching feeling.
It came in a small box and I had thought I didn't get what I ordered. But upon opening the box, the mattress inflated as if it was a ballon!!! Super surprising!Sleeping at night has never felt better. It's cool, comfortable and I feel well rested when I get up in the morning.Pretty good quality and definitely a thumbs up👍
This mattress is perfect for us because I like firm and my husband likes medium firm. All we have to do is to flip it. If there’s a time that we want soft and medium soft, we can just flip it again. Also the look of this mattress is so sleek. We love this so much!
It hugs my body just right while keeping my spine aligned. Highly recommend!
I am obsessed with this mattress!!!! It has 4 different firmness levels just by flipping and rotating and I’m never had a mattress like this! It is so comfortable and we’re sleeping better than we have in years! Will definitely be telling our friends about it!
I received my mattress and it was honestly the easiest process!!! Unrolled it and it immediately began inflating. Waited 36 hrs and couldn’t wait anymore. I am a side sleeper and have been having hip pain that had made it difficult to sleep for 5 months before making this purchase. While I can feel the firmness below the top layer, the top layer provides a layer of cushion so as not create that pain of laying on my hips! Best mattress ever!! My first purchase buying a mattress in a box. Will absolutely do it again from Sweet Night. You will not regret buying this mattress.
Very comfortable!! I wanted something that wasn't to soft, it has the right amount of firmness. Would definitely recommend!!!
This mattress is perfect, especially for the price. I didn't want to spend a fortune on a mattress for the guest bedroom so I looked online and saw this. I tested it out for a couple of nights. It may be even more comfortable than my actual bed. Thefirmnesslevel is just perfect. Gives the support needed but yet is still soft enough for comfort. I am so glad I found this mattress!
