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.

The mattress is firmer than I thought it would be but my hips, lower back and neck love it. My old mattress was really soft and squishy but I also woke up barely able to move in the mornings. I'm 63 and my body is cranky but I no longer wake up with numb arms, screaming hips or a sore neck. I'm sleeping soundly again. I guess I needed MORE support. This mattress was affordable and is comfortable and I'm very happy I bought it.

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.

Nectar mattresses are literally the only mattresses that I sleep good on. I have EDS (all of my joints are loosey goosey) and nectar seems to be the only brand my body tolerates and even loves. This is our second mattress from nectar, and I don’t see us buying any other brand ever. The price is so worth the good nights sleep and my joints not dislocated and aching in the morning. I also love that I don’t feel my partner getting up or laying back down at all.

We’ve had this mattress out for almost 72 hours with 2 nights of sleep. Was not impressed. #1 our mattress never went to its full size. Each corner was dented in and it caused the middle to be much higher than the rest of the bed. 2. It advertised this mattress as a 6.5 between firmness and softness. We needed some sort of firmness so that I could breastfeed, yet be soft enough to be comfortable. I haven’t found firmness. After sitting (or applying too much pressure at pressure points of the body) I sink so far in that my MIDDLE BACK feels the mattress. This also makes it extremely hard to breastfeed. When trying to adjust, the baby sinks into the pressure spots (as I apply more pressure than she does due to adult vs child). Even after NUMEROUS pillows, there is just no support, especially since the mattress never evened out. 3. The last 2 nights of sleeping on this mattress, I’ve awaken with pain in one of my legs. (I have to sleep on my side to breastfeed and I alternate throughout the night). And the pain hasn’t died down. This mattress was advertised to ease pain, not cause it- but I’m having the opposite effect. Ultimately, we will be trying to return this ASAP. Update!: we decided to keep it a little longer and allow it to shape/form correctly. We placed it on an actual bed support and it was immediately a change for the better. I’m not sure if all the cushion on carpeted floor was the reason, but it was night & day after putting it on a platform bed. Super comfortable, and the movement doesn’t effect everyone sleeping in the bed. Reminds me of that wine commercial mattress. I haven’t done wine, but I’ve done a glass of water and it held place while I got off the bed. It hugs your body without making you feel like you’re sinking into the mattress. Super comfortable & the mattress shaped itself out in a few days after my initial review. No body pains, better sleep, and even my husband doesn’t snore as much or as loud when he does snore. Definitely such a difference from when he falls asleep on the couch watching tv. SO grateful we gave it time & kept it! Definitely a gem for a fraction of the cost of other mattresses. 💯

I'll be honest the price was a little more than I wanted to spend but the reviews we're spot on! For a Twin mattress it feels incredibly big. Its super comfortable and as everyone who's stayed at my house the past month can contest, you sleep like a baby!!
