  • Comfy & firm
Color: White Size: King (U.S. Standard) Style: 12 INCH
I bought a queen & now I'm buying the king size. It speaks for itself how much I love this brand! It's comfortable and I love the memory foam and how firm it is. I have back issues and just love the support. I had bought the queen mattress awhile ago and once I moved I knew I wanted the king size one . The package is tightly wrapped & no cuts/tears or weird smell. It took about a whole day to inflate and become its shape and firmness. It is heavy to bring in thank god the Amazon driver helped bring it upstairs . I also wanted to wait to give review because I wanted to fully experience a few sleep nights to make sure I wasn't wrong! good price & good quality item! I'm planning to get more from this company! ... show more

  • Comfy
Color: White Size: King (U.S. Standard) Style: 12 INCH
My experience with the Sweetnight King Size Mattress has been exceptional. The 12-inch Gel Memory Foam provides a perfect balance of comfort and support. What sets it apart is its flippable design, offering two firmness options. I initially favored the plush side for its cloud-like feel, but after a while, I flipped it to the firmer side, which surprisingly offered robust support without compromising on coziness. Unboxing was a breeze, and the mattress expanded to its full size within hours. The cooling gel-infused memory foam works wonders, ensuring a restful sleep without overheating. The durability and quality are evident, making it a wise investment. Overall, the Sweetnight mattress has transformed my sleep, delivering a customizable and rejuvenating experience. ... show more

  • Comfortable but imperfections
Color: White Size: Queen (U.S. Standard) Style: 12 INCH
Some of the corners of the mattress did not rise up, we allowed an entire week for it to fully shape yet some areas just didn’t rise up.

  • Comfortable
Color: White Size: Queen (U.S. Standard) Style: 10 INCH
It was a rainy day when I received the mattress,so the outer box was a little wet, but there was a layer of sealed tape inside the mattress and it was well packaged independently. This kind of compressed packaging is also easy for me to carry up to the second floor, and it expands in a day after laying out the mattress . What I like most is that the mattress can be used on two sides, one is harder and the other is softer. There is also a cover covering the mattress.I feel very relaxed when sleeping, and the soft and hard mattress is suitable for me. And my kids find it very comfortable too. In addition, the price is cheaper than other products of the same brand. So I chose this nice mattress. ... show more

  • It is very good
Color: White Size: King (U.S. Standard) Style: 12 INCH
It feels softer on the pressure points, but is still plenty firm enough to keep my back straight. The surface design isn't felt through the fitted sheet, unlike my old one. When I wiggle my way off in the morning, it doesn't rock my spouse awake. It remains just as firm overnight and hasn't shown any sagging over the entire time we've been sleeping on it. It's the perfect balance of support & comfort, for us. ... show more

  • A very comfortable bed, firm feeling but soft enough to be comfortable
Color: White Size: Queen (U.S. Standard) Style: 12 INCH
Such a great mattress and at such an amazing price. I am a side sleeper I have slept on it a total of one week and I wake up with no body pains. It’s the best mattress I have ever owned! Well worth the money!
