This is a very nice mattress but I am slightly disappointed because I've had it for about a year now and It's already sunken in the middle. This isn't a major problem for me, since I'm single and sleep in the middle, but when my partner spends the night, we don't get a very good nights sleep since  the mattress is no longer completely flat.

I've had this mattress for ten days now, but we just received the frame and got the mattress up off the floor; it's in a guest room and has not been used yet.  The fullest part of the mattress is less than 8 inches thick, corners are not even 6 inches.  Now that it is up on the frame I can see how bowed this mattress is because of the uneven "inflation".  Very disappointed as I only bought this mattress because my son has one and loves it, he had no problems with his "inflating".  Not sure if I want to keep this, I'll wait a few more days to see if picking it up off the floor has any effect.

Ordered this a couple months ago and have been sleeping on it for about a month now. The gel top is delicious but after just a few days of sleeping in the same spot you notice a sag. I think that is part of the memory foam aspect of it but I was a little disappointed that it stays depressed. Moving around on the bed helps, so if you sleep on the same spot all the time you may notice a dip too. Over all the mattress is supportive and comfortable though.

LUCID is good and relaxing to sleep however there are issues

1) I have been using for last 6 months now, over last 2 months or so the size of mattress seems to be shrunken both length  and width wise
2)  it is not 12 inches it is actually 11.3 inches

You can only tell after you have had it a while. Sometimes they crease on there owe when you sleep on them.  I'm waiting on my review of this form mattress

I ordered the same in 12 inches and that was fine.... But this one which I ordered after 4 months that lower part of the mattress got detached. So disappointed by the product. Not sure If there is some guarantee on these ones

I love this mattress and have been using it for over a year. I have nothing to complain about the quality, but I did get a bit upset when I saw deals of memory foam from groupon, living social and other medias that selling a bundle(mattress + pillow top) for less the amount of money I spent on this one. Don't take me wrong, this is a good mattress. But for the money you spent on it, probably not worth it.

Until now, the mattress has been awesome. I have had really good nights of sleep!

My mattress: A $150 twin mattress on clearance that I got 2+ years ago. I hated sleeping on it because I could feel the springs of the mattress and I always woke up with horrible back pain. Mind you I'm only 18 years old and back pain is not something you want at 18 (or any age really).

I currently have this on top of an egg crate mattress pad and it's wonderful. Not as cloud-like as I would have hoped but it's AMAZING. I can no longer feel the springs. I'm taking this bed to college so I needed something to remedy the spring in my back situation. I slept on a queen mattress before but I prefer the twin because it's much fluffier (is that the proper way to describe beds?). When I took it out of the packaging I thought it looked a bit weird because it looks as though some of the stitching is missing as in there are squares stitched into the pad, and then there are areas where it looks like half of the square it's missing. Like a quilt, minus a few squares. It looks like the fabric just kind of trails off and doesn't want to look like a quilt but kind of does. I was worried this would come flat and not fluffy at all but alas, it was fluffy and stuffed (I wouldn't quite call it overstuffed).

I'm happy with my purchase. Super affordable and improves my quality of sleep.

Edit: as I lay on it I realize that some parts of it are fluffier than others. Where I now lay it's flat and the sides and where my feet are, are where it's fluffiest. This may be due to the missing stitching, but I'm not sure. That may be why it's not as cloudy as people have said in their reviews. I don't want to go through the process of returning it because that's always a pain. I guess I'll have to live with it. It's not bad, it's just unfortunate. It may not be a defect and it could just be the design but it seems odd that it wouldn't retain a thoroughness of fluff.

Edit again: I figured it out. Where it's stitched, it's flat. The sides are overstuffed but the middle was not as stuffed. Weird. Is this a defect?

Edit once more: Went from 5 stars to foure stars and now three stars. Others have said their stitching/seams are fine, so the one sent to me seems to indeed be a defective one. I'm really upset about it because I was so excited about this product, only to receive one that wasn't up to par with all the others. I tried to get a replacement but that wasn't listed as an option for the product. I wouldn't mind returning it and ordering again but I'm nervous that I'll get another messed up one. I don't really know what to do. I'm quite dissappointed though. I just wanted to know what sleeping on clouds would feel like :(

The good- this mattress is SO comfortable. Im a stomach sleeper and it isn't too soft but not too firm either. It was easy to unpackaged even all by myself. The total weight was about 70 pounds. The price is unbeatable!

The bad- as seen in other reviews, the 12 inches did not fully expand. Youll get about 10 max. I don't know why, possibly because of what it is made out of but this mattress absolutely wreaks. It has sort of a toxic/chemical/burnt smell to it. Not sure how long its supposed to last.

Ill update in about a month so see how its holding up.

Bought the Ultimate Dreams Latex Mattress based on the positive reviews. Had for three years and loved it for the past 2 years. Recently it has started to bother both hips. I'm a side sleeper and back sleeper, think the foam has deteriorated a bit over the years. Overall it was a good experience and quality mattress but probably not the best choice for me. You have to be proactive with Latex foam matresses and not keep them too long. Recently bought a Lucid 10" Latex mattress, hope this lasts a bit longer. Will review in future.

Well I'm not one to make reviews but this was a little disappointing. I purchased this mattress 02/16. At first the bed was very good, a little soft for my taste but still comfortable. After about a year I started to notice the mattress sagging on one side. This is the side I usually sleep on. So I started to sleep on the other side, thinking maybe it would help distribute my weight across the mattress. In the middle of the night I still find myself sinking into the sagging portion of the mattress. I called the customer service department, and when I called the warranty department was closed. I was told they were closed before transferring (so not a huge deal) but was told to leave a message and I would receive a call back. 2 months later still haven't received a call back.... kind of disappointing. I can still sleep on the other side but at this rate ill probably end up throwing this mattress out in a year... personally I wouldn't buy again.

Very Comfortable mattress but it doesn't fold well. Slides down the frame. I've had the mattress in our guestroom/playroom for 2 months in the upright position and there has been no improvement. It is a lot more comfortable for my guests than my previous paper thin mattress but its not very appealing.

Mattress is very comfy. Seems to be a good replacement for the beaten up one we own. Reason why I gave it 3 stars and not 5 is because although the mattress took shape within an hour after opening it, the corners are slightly smaller than the rest of the mattress. There is also an indent on one of the corners, which tells me the foam is separating on the area. All of this being said, the mattress looks good and it's quite comfortable, but I'm a perfectionist and this is not perfect. So 3 stars it is.

The mattress seems to be well made. It is not one that can be flipped over to use the opposite side if you're considering rotating it in that manner. For me the mattress is extremely firm. If feels as if I am sleeping on top of it instead of being cushioned by it. I find I wake feeling sore in pressure areas. I had to add a thin memory pad to get any comfort. It did sleep cool the night I slept on it without the additional pad. I was really disappointed in the way it was shipped. According to the tracking, it's still not here. The box was open on both ends and it appeared it had been dragged to my door, and it's a wonder that it didn't slide out. If it hadn't been for all the plastic around the mattress, I would not have accepted it. It comes sealed in plastic which is rolled up, then it is rolled in plastic which takes about 10 turns to unwrap.  Once that is done you come to the sealed plastic. Once snipped, the mattress immediately starts expanding.  By the time I had the plastic entirely cut and pulled off, the mattress had fully expanded. I recommend that you do all this on the bed frame that you're going to use.  I did not notice any kind of odor. I've had the mattress for about a month now and it is still taking some getting use to. My rating is for the fact that it is not the medium firm but extremely firm (my experience) and that it can't be flipped over. If I figured in the shipping it would only get 2 stars.
