Soft but not too soft! Getting much better sleep after adding this. It expanded out of the package to its full size in just a couple hours. There was a faint smell but nothing noxious. It does hold heat but all memory foam does. I’m perfectly comfortable as a stomach sleeper and so is my husband as a side/back sleeper.

Seriously, my prayers have been answered. I only wish I would have thought to invest in this mattress topper while I was pregnant. It might have saved me a huge headache (literally). I've never had much luck with mattresses, but I've never really blamed the mattresses - because I suck at sleeping. Apparently, I'm a contortionist in my sleep and do things with my body that would give little Linda Blair a run for her money. I wake up a million times a night with pains in my head, my neck, my back, my hips, my legs, literally everywhere. However, I've had a friend come over to help with my new baby and I happen to have the same mattress in the guest room that I have in my main bedroom. She brought it up to me one day that her hip and lower back were killing her since sleeping on the mattress in the guest room- even though it is a pretty expensive pillow-top brand. She asked me if I could order her some kind of mattress topper from Amazon and she'd reimburse me. At this point, I had been in so much agony myself that I got two - one for the guest bed and one for mine. And if it weren't for the fact that I only have nightmares, I'd insist that I'm dreaming up this amazing experience with this mattress topper. I mean, I really don't even have words for this thing. I'm not pain free - because, well, it's gonna take a lot of time to undo that kind of damage. But I have noticed a dramatic difference. My body feels so soothingly cradled. I'm not tossing and turning constantly trying to get comfortable. It's just pure bliss. This may sound strange, but it feels like a hug. It does. It really does. Like a hug from the Pillsbury Dough Boy. Some Technical Details: 1) It was very easy to set up. 2) There was only a very faint odor that dissipated almost immediately. 3) I was so desperate to use it that I didn't even wait the full 48 hours as suggested but it seemed to be super plump straight out of the box. The density is perfect for me. 4) It fit absolutely perfectly across my king-sized bed 5) It appears to be of durable quality unlike some toppers I have seen or used in the past that easily shred or discolored. Time will be the ultimate test so I can't 100 percent guarantee this but judging from observation this would appear to be the case. I will update as necessary. 6) It does live up to the claim about not retaining heat and keeping the body a cool and comfortable temperature (which is crucial for a person like me because I practically need to live in an igloo). So yes, I'm very impressed thus far and absolutely I would recommend this to anyone and everyone. I've honestly never been this excited to go to sleep. My fiance loves it and he was a bit upset that I got it in the first place because he loved the mattress the way it was, but now he loves THIS more. And even my little doggie who has become a neurotic mess since my baby was born seems to be a tad more comforted and peaceful sleeping next to me now. Just writing about it makes me want to go upstairs and jump in bed. I'm starting to wonder if they put something inside this thing if you know what I'm talking about, because I'm addicted. Just kidding... Maybe.

Oh, the Lucid Topper, so soft and so blue, It arrived in a box, and it knew what to do! I unpacked it quick, with a zip and a glide, And in less than an hour, it puffed up with pride! My bed was too firm, a bit hard like a rock, So I got this soft topper, thought I’d give it a knock. And soft it sure was, like a marshmallow dream, You sink right in, like you're lost in a cream. But beware, dear shopper, it's squishy, you see, If your bed's plush already, it might not be key. For sinking too much, oh, you might get stuck, So firm beds only, to really press your luck! It slides just a bit, so don't toss too wild, Or you’ll wake up slanted, like a giggly child. The cover I got? It was loose at the seams, With strings hanging out, not as neat as it seems. But all in all, I’ll give it a cheer, Though not perfect, it’s cozy, and brings comfort near. A 4 out of 5, not bad, I’d say, A good choice if firmness keeps sleep at bay!

The most important gift you can give your child is a comfortable bed while they’re away at college and I’ve purchased 2 of these for my boys. Good brand, good price, super comfy.

So I've always had normal aches and pains ever since I can remember. I've had the mattress that I currently use for probably 7 or 8 years, so I'm aware its probably time for a new one. Anyways, my normal aches and pains, these last couple of months have been just awful. My hips and my neck, my back and my legs, you name it, it all has been hurting when I wake up in the morning and when I would try and fall asleep. When it first started I attributed it to bad pillows. Which could still be the case, but I purchased a Casper pillow (supposed to be the best of the best) and not only did that not help with my issues, but I felt like my aches were becoming worse. So scratch the pillow its got to be my bed right? Well yes, no question about it, I've had it for a really long time and in mattress years it's time to trade it in. Not only is it old, but it's one of those mattresses with a kind of "built in" padding on one side, and a hard, flat bottom on the other. So that recommendation on flipping your mattress something like every 6-8 months, I've never been able to do. You can see where I mostly lay down at night from the slight indent that has finally begun to show itself. So to make a long story short, I desperately need a new mattress. There are some issues with this though. Money for one, I don't have a couple grand to throw down on a beautiful TempurPedic mattress, no matter how much I wish I did. My measly Veterinary Nurse salary just allows me to pay bills and save a little which will eventually all go back to my school loans. So I was back at square one. I of course had been complaining to all of my friends and family about my aches and woes me, hoping someone would take pity on me (just kidding) but really I've just been some uncomfortable and barely able to sleep its like the first thing that's on my mind when I go to talk to anyone. In mentioning my issues with my old mattress to my friend Brooke, she asked me if i had ever tried a mattress topper. I had in college but it wasn't anything special. She said that she had recently just got one (not this exact product) and that how its changed her bed completely and that anyone who has ever sat or laid down on it has always commented on how comfortable her bed was. So I started looking, and looking and then not looking and looking again, because regardless of a mattress topper being significantly cheaper than a brand new mattress they still didn't seem cheap if you wanted one that was going to be good quality. In one of my not looking phases, I really hurt myself at work restraining a dog, and for days I was barely sleeping. Tossing and turning, miserable because not only was I in pain from my work injury but my bed was the absolute worse. Finally I was like that's it, I'm done, I'm either throwing this mattress out and becoming a person who sleeps on the floor or I'm just going to bite the bullet and buy a mattress topper. That same day I started looking and stumbled upon this guy. The reviews were all nothing but positive. The price seemed very reasonable and so I pulled the trigger and decided to purchase it. It came within only a few days, and I was so excited. I had read in reviews that some people were like me and couldn't wait the full 48hrs that the instructions tell you to wait for it to fully expand. I made it roughly 28 hrs before I decided that was enough. There was no smell to it that I or my sister could detect and it really did expand significantly from when I first opened it. My queen sheets fit snugly over it and maybe not as well as i'd like them to, but they do fit and its not anything that would be an eye sore. That first night I went to lay on my "new" mattress wasn't too bad, but to be honest it wasn't what I had hoped it to be. When you first sit on the topper it feels firm but soft and you slowly start to dip into it. When this first starts to happen its not so bad but after you've laid in one position for too long it felt as if i was laying on my old mattress again. That first couple of nights I was close to tears because I was so frustrated that this wasn't what I hoped or thought it would be. But then all of a sudden, I want to say like day 4, maybe 5, I stopped sinking in as much. I ACTUALLY slept through an entire night with minimal tossing/turning. Ever since that night, the mattress topper has been pretty much what I expected. I'm thinking that i really should have let it sit out for the full 48 hours, maybe even 72, and that when it finally started to feel comfortable was because it had maybe finally expanded to its full potential. Would I recommend this product? I would. It really isn't so bad now that I've had it for a couple of weeks. If i had to do it over I would A: probably buy a topper that said it was more firm and B: definitely let it expand the full recommended time, plus maybe a little more. This mattress is great if your dying for some relief and need something that isn't going to break the bank but is decent quality. I'm only giving it 3 stars however due to the fact that I feel like they didn't describe in enough detail how firm it really would be. Good product but flawed.

Me and my wife looked at a sleep number bed over the weekend (Memorial Day sales). After receiving a final quote on a bed we liked, over $4,500, we decided to sleep on it and reflect on the things we liked. We both realized we thought we liked firm beds for back support, but our comfort number turned out to be in the 30’s. We both appreciated the conforming feeling and how it alleviated joint paint. So rather than applying for a small loan, I thought we would try modifying our current mattress with this cooling mattress pad and applying it to our 8 y.o. Zinus Memory foam mattress I bought on Amazon when I bought my house. We flipped our mattress over to the hard, supportive side and put this on top of it. Let me be clear, we both slept like royalty that night. Woke up with no pain, no soreness, and well rested. A solid investment all around. If you’re considering a new bed because you’re sleeping hot, changing positions often, or feeling stiff in the morning; I firmly encourage you to consider this as an option.
