We decided on the spur of the moment to finally upgrade our mattress during this past prime day sale and ended up getting a great deal on the King sized Nectar Mattress. It was half off, I’ve heard great things about these beds in the past and after carefully doing some research just to make sure it would fit our needs, decided why the heck not and purchased the bed. It came within three days and after setting up a new bed frame for it we unboxed it-which I would do with help as the box is heavy and the sealed plastic covering the bed is a little harder to get off alone, although I’m sure someone could do it by themselves but would be much easier with help. Some reviews said the bed takes days to fully inflate but ours inflated fully within moments, almost instantly. The picture attached to my review is taken not even twenty minutes after we unboxed the bed. It is firm but also has the memory foam feel that has your body sinking in slightly and conforming to your body as you lay down. I’m a shorter, bigger woman about 260 lbs and it’s just the right amount of soft and firm for me. I add that because some people have suggested that the hybrid model mattress is a better fit for larger people as the medium firm model may be too firm and uncomfortable for larger bodies. I’m so ridiculously comfortable and relaxed in this bed and have slept better than I have in quite a while so that’s not the case for me at least. My fiancé is about 190 and taller and he’s equally comfortable and satisfied with the bed. This is simply the best mattress we’ve had in ages, only to be rivaled with our old Tempur-Pedic we had years ago which was the best sleep I ever got on any mattress in my twenty some years of life. This bed is up there on that level though and more affordable so I’m extremely satisfied with this purchase. If your debating whether to buy this bed or not I wouldn’t wait, amazing sleep and comfort are just an order away!

Incredibly comfortable. I do find it relatively softer than the medium firm mattress from other brands but it's just about right for me!

This is such a nice mattress. I can’t believe I only paid $600 for it. It feels like a premium mattress. It’s not too hard or too soft, it’s just right. It was something I was worried about when I purchased this. I really hate most memory foam mattresses in the market, because over time, they tend to sag. I waited for a while before I decided to write my review, because I wanted to see if it would sag. But it’s delightfully comfortable and still as great as when I first tried it. I’m very impressed by it. I used to sleep on a beautyrest BLCK before this, and that’s a great mattress, but it’s really expensive. When I moved, I needed something good, but within my budget. This bed in a box delivered! I’m so glad, I feel like I have definitely gotten a good return on my investment with this mattress. It was very easy to set up. All you have to do is open the box, roll it out into an open space, and tear the plastic wrapping off. The mattress starts inflating as soon as you do. I put it on the floor so it would inflate at a completely level surface. I went on a business trip, and I came back, it was ready to use. I mounted it on my bed. It looks great. I’m fairly average in weight and height. I sleep on this alone, and it’s really great. I think another average sized person would sleep well on here with me. I don’t feel hot, but then again, I bought this mattress at the start of a very cold, bitter winter. I did put a mattress protector on it, which could also be why I don’t feel hot. The warranty was why I bought this mattress and not any other bed in a box. I felt at ease spending the money. I read other reviews of people remarking about how expensive this mattress is. I don’t get it. It’s a great value. You sleep most of your life, it’s the place you spend the most time in, get something good.

Firm, much firmer than expected. My wife and I both weigh under 200 lb and find it comfortable. We had an old serta memory foam mattress which was about twice as soft as this. We wanted something a little firmer but it turned out twice as firm after sleeping on it for a couple weeks now but its comfortable! Soft, imprints to your body just enough to not be completely stiff. I highly recommend this to anyone who is heavier (225 plus) and likes a more firm mattress.

Should have ordered this sooner. Is a little on the firm side but once you break it in, if you know what I mean, then it is perfect. Great quality, great price and definitely keeps me cooler at night living in those Florida summers.

The Nectar mattress is seriously a dream. It’s the perfect mix of soft and supportive, I wake up without any back pain and actually feel rested. It arrived quickly, was easy to unbox, and expanded right away. I didn’t realize how much a good mattress could change my sleep until this one. Definitely worth every penny and a must-have for better nights

I had a $2,000 Beautyrest mattress that started to sag after just one month, and they wouldn’t honor the warranty. I was stuck with it, and after two years it got so bad I couldn’t take it anymore. I decided to buy this one instead it cost way less and is a million times better and more comfortable. Even when the Beautyrest was brand new, it wasn’t as comfortable as this. I got the 12-inch Classic, and it’s been amazing!
