  • The bed to rule them all! 👑🌌
Color: Grey Size: King Style: 12 Inch Foam Mattress
If you're researching memory foam mattresses and happen to land on this one, let me tell you, you've found a very wonderful option! I am IN LOVE WITH THIS MATTRESS! 💖Took me some time getting used to, coming from a cheap Sealy Posturepedic Spring Mattress from Big Lots. It was breaking down and my boyfriend was lying in a pot hole and a good night's rest was very difficult for him. So I had to splurge on this one and was very nervous. My 1st "bed in a box," so to speak. I chose this because it seemed more reasonably priced than anything else I could find. He wanted to upgrade to a King from our Queen. So I had to buy a new frame as well. Overall, didn't want to spend a ridiculous amount of money for just a mattress alone. Of all the stores we went in to, all the research online, lead me to this one. Good price and had great reviews. Crossed my fingers. It arrived at the doorstep; a big heavy box. It didn't have any indication of the correct size other than the fact it had a big "K" on it. We hoisted up on to my newly put together frame and immediately after cutting all the plastic off, it began to inflate. It was pretty cool to see; took all of 5 minutes to reach full potential. It was a freaking BEHEMOTH! I was so nervous to have something so big, but excited after what we've been sleeping on previously. Such a drastic change! I was worried a "12 inch wouldn't be tall enough, because these things can go up to "14, but it is definitely enough. It's so tall! Goodness. I have to hoist myself up onto the bed. Nonetheless, I plopped on it right away. The thing that I love the most, is the way it inflated beautifully. The corners and edges are very cut and prominent. I like that. No sagging or dead spots. No lumps, no unevenness, just perfectly level all across the board. 2 months in, and it still holds up beautifully. No smell, no allergies, etc. Just totally clean and spotless. It's absolutely perfect. The feel, I expected it to be more plush, which is not at all bad. It's still very soft and comfortable. It's very different from a spring mattress that's for sure. It seems true medium-firm. No sinking, however, it cradles your body ever so slightly; contouring your curves and really feel you're getting a good balanced alignment within your body. I thought I would rather have a more "sinking" feeling within the mattress, but my body sits just ontop. Very dense and sturdy. I've managed to get used to it and feel like it's perfect now. I am currently using a brand new waterproof mattress protector, so that may have some added firmability. It's motion-isolating and quiet. Very roomy. And visibly appealing! Such an incredibly GORGEOUS pattern! 😍 It almost sucks to have to put sheets on it. I feel like I wanna show it off somehow! I've bought satin sheets to lay on, for an even more cooling effect than it already has. Such breathability! I sleep so very good and wake up refreshed. I don't experience back pain like I used to when getting out of bed now. And my boyfriend sleeps like a baby. We don't wake eachother up by our movements anymore either. I actually look forward to going to bed now, even if to just to "hang out" in it. 😊 LOVE, LOVE LOVE! I think anyone who buys this, will be 100% pleased. I swear by it. I've paired this with a Zinus "Justina" frame, where it's practically a box frame and frame in itself. Also wonderfully priced, about $165 for a King. The mattress itself hangs off by an inch of the frame, but it's still amazing. I've left a review for that as well. I'm not 100% certain it will work with an adjustable frame, seeing as it's really dense. There is a hybrid version of this mattress, in blue, if you'd like one with springs. Be sure to check that one out. But this grey/black one, is all memory foam. All in all, if you wanna compare this mattress to something to help you decide, go to Mattress Firm, where they have Nectar mattresses on display. The best one, the Premium Copper, I laid on it and it was heaven. But didn't like the price! It was $1,499.00 for a King! Mattress only. You can't return it, only exchange. And the adjustable frame is non returnable. This bed is the exact same quality and a lot less money than you'd pay for a popular big brand. More bang for your buck. According to Sweetnight's brochure that comes with the mattress, it comes with a 10-year-limited warranty and 100-day-trial. It's a nice to know that it's covered, but I'm happy to say, I'm definitely keeping it with no complaints. Should I need to buy another, this is the brand I will buy from. It's worth checking out. I did and I couldn't be happier. If you like the Nectar bed in the store, you'll love this mattress from Sweetnight.🖤 ... show more

  • Perfect Firmness For Me
Color: Grey Size: Full Style: 12 Inch Foam Mattress
Just making a quick review. I took a gamble on this mattress since it had only 50 reviews at a 5 star rating when I bought it; I thought maybe it could be bots or spam, but alas this mattress truly is everything I wanted it to be. The mattress/mattress cover looks great, it's firm but not like sleeping on pavement, and it expanded to its intended size in about two hours or so for me. I gave it about 12 hours before sleeping on it, ignoring the 24 hour rule, and it was definitely enough time for it to expand. The corners aren't sharp and pointy; they're just roundish. The bottom of the mattress cover has rubber grips, which helps a lot on a platform bed frame. In conclusion, if you're looking to save money without losing quality and you want a firm mattress, this is the one to buy. Stop hesitating and just do it. Keep in mind, it's memory foam and can get warm when sleeping! ... show more

  • Sleep tight! Starry, supportive, and pleasantly scented.
Color: Grey Size: King Style: 12 Inch Foam Mattress
I love the design of this mattress. It's the perfect balance of support and comfort. The difference in my most recent mattress and the one before that is night and day. This is the perfect amount of thickness and shape. Having a small box and then the amount of time it took to expand was awesome! I don't have the sinking feeling when I lay on this mattress and move around. I will have to update as time passes, I am confident though that this was a worthy purchase and having the proper frame will increase it's longevity. There is NO adverse or pungent scent from this mattress. Every other mattress of different brands I have purchased has always had some bizarre and off-putting odor to it. Not this one! It smelled like "New mattress" like the ones you find in the furniture stores on display. Setup was simple! Open the packaging, lay it out, let it rise like a bread loaf for 48-72 hours and relocate to desired placement. This is HEAVY, so it will take multiple people to move. No other mattress has met efficient functionality. ... show more

  • Second time buy.
Color: Grey Size: Full Style: 12 Inch Foam Mattress
Second time buying this product. Got the full this time,(first time a queen). Absolutely love this mattress that I needed to buy another. Soft but firm. Mattress is the perfect thickness fits the bed frame beautifully. No box spring needed depending on the frame you have. Box is heavy so definitely need two people to carry it and get it out of the box. Make sure you have room when you open it. Material is amazing. Very easy to set up, comes with the tools you need to open it the mattress itself out of the plastic. Comes with a manual and everything. ... show more

  • Medium firm comfort with snazzy dark cover
Color: Grey Size: King Style: 12 Inch Foam Mattress
This is my second buy from this brand. I was hoping this would be a little more plush like the other version I bought in a smaller size. I like the convenience, price, and weight of this bed in a box especially in comparison to the ridiculously heavy hybrids that are popular. We move a lot for work and this will be more versatile. I especially like the appearance of the dark cover. I use a mattress cover anyway but when you take the sheets off to wash (or move), this is prettier to look at and shouldn’t have to worry about discoloration or dirt stains like can happen to the typical white mattress. I was concerned the dark would be a problem for lighter sheets that it might show through but I haven’t noticed it so far. Even though I wish the top layer was a little more plush than squishy, I am happy with this mattress. It is comfortable and I’ve had no shoulder, back, or hip pain when sleeping on it. I fall asleep on my side but I sometimes wake up in the morning on my back, so apparently both positions are quite comfy on this mattress. Also, I’ve had no issues with overheating on this mattress as I’ve experienced with other brands. ... show more
