    • An amazing mattress for the price!
Color: Gray+white Size: Queen Style: 12 Inch
Even though the "soft" side of this mattress is still a little firmer than I would have liked (I'm hoping it will still "give" a little more as it gets wear), I have to say that this mattress is a screaming deal, especially with a $50-off coupon I was able to snag when I ordered it. There is NO WAY I will ever go back to a brick-and-mortar "Mattress Something" store! What a rip-off! This mattress is well-made, clean, well-packaged, and expanded beautifully with no wrinkles or unexpanded corners. I was comfortable immediately, and I love that it's flippable. I don't think you can go wrong with this! ... show more

    • The Perfect Solution for Guest Rooms or Different Sleep Preferences

I was looking for a flippable mattress for my guest room, so I could easily adjust the firmness depending on my guests' preferences. I also wanted a mattress that was packaged well and wouldn't be too difficult to set up. This mattress exceeded my expectations on all counts! It is very comfortable, and both sides provide excellent support. The firm side is perfect for people who like to sleep on their backs or stomachs, while the soft side is ideal for side sleepers. My guests have all commented on how well they slept on this mattress. The packaging was also very impressive. The mattress arrived in a box that was easy to open and maneuver. The mattress was rolled up and vacuum-sealed, so it was very lightweight and easy to carry into my guest room. It expanded to its full size within a few minutes of opening the box. Overall, I am extremely happy with this flippable queen-size mattress. It is comfortable, well-made, and easy to set up. I would highly recommend it to anyone looking for a versatile mattress for their guest room or for their own personal use. ... show more

The quality of the mattress is outstanding, reflecting a clear dedication to both comfort and durability. I like the double-sided design, offering a firm side and a soft side. It's like having two different mattresses in one, allowing the user to customize their sleep experience based on their comfort preferences. We have the mattress in our guest room while one friend visits us. The experience is great! It offers good support to the body and relax during the night. She prefer a firm mattress and she likes this mattress. The packaging was also good. The mattress arrives in a box which easy to open and the mattress is easy to set up. It was rolled up and vacuum-sealed. I am happy with this purchase, the mattress meets my expectations and works great for my guest room. ... show more

    • Like a cloud!
Color: Gray+white Size: King Style: 12 Inch
***Update almost 4 months later*** Well, it’s true that, at first it felt so good but now, not so much. Thinking back, it likely felt so much better because I had my old sunken mattress as a comparator. Lesson learned. Unfortunately, I was away and hadn’t slept on it for about a month and when I came back, within two weeks of sleeping on it, I started having, trouble with pain in my hips and shoulders. I flipped the mattress to the firm side and that was much too hard. I Tried my 3 inch mattress topper and that didn’t work so I bought a 2 inch mattress topper and it was still too firm. I flipped it back to the soft side and tried the two different mattress, toppers again, to no avail. By this time, I had gone beyond the 100 day trial/warranty. But Amazon was kind enough to refund it anyway. I bought a mattress of a different brand and it arrived today so we will see how it goes. ***original post December 2023*** This mattress is like what I imagine sleeping on a cloud might feel like! It’s the perfect level of firm support to prevent awkward body positioning and to prevent pain on the pressure points (side sleeper). The top layer of softness is like a warm hug! It’s only been one night but if this is any indication, I’m going to have many years of good sleep with this mattress. The best part is it’s FLIPPABLE! Had my previous mattress been flippable, I could have gotten many more years out of it. Being able to flip this mattress should give me at least 20 years before I have to buy another! ... show more

    • Not to full shape and its been 72 hours
Color: Gray+white Size: Queen Style: 12 Inch
I was excited to get this 12 in mattress it looks really nice. I removed it from the packaging and it started to inflate but now we are at 72 hours and the corners are only at 8inches and the in the middle of the mattress is 10 inches. I am not really sure how this gets resolved, I have an email out to SweetNight but not sure anything will come of it since its already opened. I will update the product information once I hear back. Update: I have been in contact with Sweetnight and their customer service is outstanding they are still working with me on getting it resolved. The quality of the mattress is good and we are sleeping on the firm side because that filled out better. I still would recommend the mattress, the middle of the mattress expanded to 12in but our corners are still at 10in. But even though there was an issue; having a company reach out consistently is a refreshing change, thank you Sweetnight! ... show more

    • First Time Memory Foam Mattress User
Color: Gray+white Size: King Style: 12 Inch
I was in need of a new mattress, and I wanted to try out a memory foam one. I always have gone to try out mattresses in store, and have never purchased a mattress online. I was hesitant, but figured I would give it a try, given the affordable price point, and for the convenience of it being shipped to my house. The mattress came sooner than expected, and I was shocked to see a box sitting outside of my front door! I was not sure how a huge king size mattress could fit in there! However, I opened the box and followed the instructions to let the mattress fully expand on the floor. Once it was fully expanded, I moved it to my bed. It was a great height, and looked so comfortable, so I could not wait to try it out! My first night's sleep on this mattress was wonderful. It is not too soft or too hard, and I could not feel my partner's movement at all. I am definitely going to tell my family and friends to purchase this mattress the next time they are in need of a new one. ... show more
