amazing sleep. (update 2 years later)
352455
2-Year UPDATE (6/2017):
It's held up pretty well... It has stained from body sweat, which is a little gross, but whatever, I didn't get a protector so what do I expect? I had 2 surgeries this month, so I'm in bed A LOT now, and unfortunately this mattress topper is just not as comfortable any more. My back hurts, my hips hurt... and I'm now looking at upgrading to maybe the 3" (the 4" has questionable reviews about being too soft). I wish I could trade it in since it's within the warranty time period, but know that it likely won't qualify, which is a shame. Again, it's not a bad topper -- especially given the huge price cut it's gotten since I first bought it -- but it's just not the topper for me any more. Hopefully the 3" will be better.

ORIGINAL REVIEW:
I had the LUCID 2.5 inch gel infused memory foam topper for a twin bed, and LOVED it. Recently moved out of my studio apartment, so I was able to get my full sized bed back. While I was excited about getting my old bed back, I was sad to lose that memory foam topper. Decided this time to go with the 2 inch on from LUCID to save some money.

Only took a few hours before it was basically to full size. I had no issues with the travel bag. The smell also went away super quick, I don't even remember noticing it that first night. I do prefer the 2.5 inch w/ bamboo cover to this 2 inch, BUT that said, the 2 inch is amazing. I sleep so much better than I did without it. The 2.5 inch was a bit firmer, but you still sank into it. This one I feel more like I nestle down into it. If I'm sleeping on my stomach, I don't really even need a pillow with it. I can't imagine sleeping without one of these gel infused memory foam toppers. Highly recommend getting one.

Also, one note regarding the "cooling" affect or whatever. This mattress topper is not an ice pack. It's not going to lower the temperature of your bed. No mattress topper does that. What this does, however, is keeps your bed from increasing in heat. Memory foam toppers sometimes have an issue where they cause you to overheat in bed, these ones do not have that issue. That's what this whole cooling thing is about, keeping you from overheating.

Update. 03/17
I've owned this mattress for about 2 years now. The mattress no longer holds air. I have checked the mattress multiple times with soapy water to find any leaks. None were found. My only guess is it has to be leaking from the pump. The original advertising video shows the company deliberately stabbing the mattress with a knife, and the secondary pump being able to keep it inflated. I can't even find the leak....and it still can't keep it inflated. In a sense it was worth the money, but considering it's still in great shape and only used 10 times in last 2 years...would expect it to hold air. Still cheaper than a hotel!

Sets up in minutes.  The "secondary" pump is very quiet even though it runs constantly.  Bed is at a comfortable height level, even for my 60yr+ in-laws.

My husband and I have been sleeping on this mattress for four months now.  This is our first memory foam mattress.  I had a foam mattress (not memory foam) when I was a teenager and I remember sleeping great on it.  I have sporadic back pain in different spots in my back.  My husband snores and moves around in his sleep like he's a walrus!  He gets up for work at 3:30 am.  Needless to say, my sleep has suffered for years.

The first few nights took some getting used to.  I did feel slightly achy in the morning, but it quickly wore off.  Nothing serious.  That initial "breaking in period" barely lasted four or five days.  The best part of the mattress to me, is my husband does not disturb me at all.  Many mornings I awaken to see he left for work, and I never even was aware of him getting out of bed!  I have had more nights of solid 7 hours of sleep, without frequent awakenings on this mattress than I've had in years!  Oftentimes, when I wake up, I see that I've actually been in the same position all night.  That's great sleep (for me)!

As far as it being cool/hot--I've not noticed either.  We bought this is August, when it was 90 degrees outside, and about 78 degrees in our poorly cooled bedroom.  The mattress never felt hot.

After four months, there are no areas of indentations.  I've 5'7", 160 pounds.  My husband is 5'10", 225 pounds.

Also of note--There was no odor and it inflated immediately.  I did not wait too long and we slept on it about 7 hours after we set it up.  It arrived in a very heavy box, which took two people to bring upstairs.  We didn't even unpack it for about 3 days.  We laid it on the bed frame before unboxing.

Ok first things first, let me say that what attracted me to this mattress was the ultra plush in the title.  After sleeping on this thing for almost two weeks I have to say that if you consider ultra plush meaning that the bed is nice, fluffy, and soft then you may want to look elsewhere! That being said when it comes to a mattress we prefer a medium firm mattress since we are side sleepers.  This is  a little harder than expected but after using it I honestly would  gladly buy this again.  I am not small in the least bit I'm 5'11 300lbs and pretty muscular, when I sleep on a box spring I find myself tossing and turning through the night due to pressure points like my shoulder and hip.  With this mattress I have yet to wake up to toss and turn during the night.  I also noticed that I am also sleeping better because I am not subject to feeling my wife move during the night either, I honestly did not realize how much her movement impacted my sleep until we started sleeping on this mattress.  The first few nights it took some getting used to but I honestly do not plan on going back, this thing has worked wonders! I sleep better, and hardly move during the night due to the comfort level!
I know that it sounds crazy but my quality of life has improved a bit just because I am sleeping better and fully, I found that it was amazing waking up the next morning without getting up during the night.  I am happy with my purchase and have already recommended it to family and friends.  When it is time to purchase another mattress I would gladly purchase this one again.

UPDATE!
Just a friendly FYI I read online that in order to break your mattress in and make it a wee bit softer you could walk on it, as crazy as it may sound after a month of it being a little harder than we would have expected we let the kids jump and walk on it and that actually worked! It only took one time of that happening to make the bed noticeably softer and give us a even better nights sleep!!  So if its too hard then try walking circles around the mattress, what do you have to loose other than a little time and effort?

After sleeping on this mattress for about a month I must say I still absolutely love it! I had back surgery in May 2011 L5/S1 herniated disc with nerve damage. I was convinced I would never have another good nights sleep. Well, I figured I would give this a try since other reviewers commented on it being firm and supportive, which was what my worn out Serta mattress no longer provided.

Sadly my wife opened the mattress while I was at work so I didn't get to see it unroll..... Dangit! But, after letting it expand for one night I had to give it a shot. The first night or two will take some getting used to if (like me) you have only had spring type mattresses in the past. I wouldn't say it cured my back pain, but it certainly helped take the edge off, and that alone is worth the asking price.

Bottom line, I love it, and I'm glad I took a chance!

I read all the reviews on this before purchasing and I am not disappointed. I bought it well over a year ago, maybe even closer to 2 years ago, and I am very very pleased with the purchase. The cover that it comes with is thin and began to tear. I will need to order a replacement fitted zipper sheet for it but this will change the way you sleep and transform your mattress! Back problems disappear (reasonably) and quality of sleep is much better! 5 stars!

I ended up purchasing this mattress after reading all the reviews.  With only a few reviews being less than good I decided spending $700 was worth the risk.  I had gone to the big box stores and spent thousands after laying on mattresses after laying on them for a few minutes and ended up hating them. I was also researching Loom and Leaf and other box mattresses but I trusted Amazon reviews more and the customer service of Amazon. And the price to risk ratio made more sense.

The mattress arrived on the day it was supposed to. The box was a little beat up but it was pretty heavy so i expected that. It was wrapped in 2 layers of plastic, a heavy outer plastic sleeve and thinner inner plastic wrap.  There was no damage to the plastic.

We ordered a King and it was heavy but very manageable with two people.  The plastic was easy enough to get off and it layed out right away. I noticed a very slight smell when the plastic first came off but it literally only lasted a minute. I expected it to be worse as I am very smell sensitive.

It states you need to let it reform for 6-8 hours but we decided to give it 24.  It was fully formed in 6 but since it was delivered in Iowa in January we wanted to give it time to warm back up. It may not have mattered but since it is a considerable amount of money it seemed worth it to us to give it extra time before putting weight on it.

Last night was our first night on it and I am impressed.  I slept from 10p- 6a and I can't remember the last time that happened. I slept sound and didn't wake stiff and sore even after having a physical day of moving and stacking firewood.  The dogs didn't even get me up at the usual 4a so they must have liked it too.  Yes some of our dogs sleep in our bed, that is why we upgraded to a King.  My husband and I weigh between 140-170.

I will give it a break in period and edit my review if neccessary after 30 days.  For now I would reccommend!

**update after sleeping on for one year** February 2018

Still happy with this decision.  The mattress is still comfortable after sleeping on it for just over a year.  There is no sinking spots or issues at all.  We thought we had an issue a few months ago but it ended up that one of our supports had slipped, fixed that and it was good as new.  I may eventually want a slightly softer mattress but I anticipate having this for at least 10 years and that was worth the money compared to a $1500 - $2000 mattress.

I've bought and used many different air mattress, this is the best one among them. Way better than some that are more expensive than this. This is so quiet at night, it actually feels like a real mattress. Since I inflated it the very first night, it hasn't lost any air. It has stayed at the same firmness for over a month. I bought a second one for somebody. I highly recommend this air mattress.

Update - 12/16/2017
I've loved this airbed and slept on the same one for almost 2 years with no problem. I only topped off the air once a week. In the past couple of days, all of a sudden, I'm loosing air so fast. Pump air into the mattress every night before I sleep on it and by morning it's all soft. I don't know what happened. This air mattress I've loved so much is giving up on me!!

After two surgeries during six months I have slept. on the Insta raised twin bed to be downstairs. Superb quality, very, very comfortable in the firm mode I am using, and a breeze to inflate. Getting sheets on is a bit of a challenge, but works out OK.

Updated New Review:
We just bought a second one for our beach house, so we now sleep on this topper at home and at the beach.  It is the best thing for my back.  Before adding this to our beach house mattress, my back always ached, now I have no problems while using this new topper.  Highly recommended, we have used the other one for 5 years and it is still in great condition, plenty firm.  The topper comes compressed and rolls out easily on to the bed, only takes a few hours to get to it's full size.

2011 Review:
My wife and I have back problems so we bought a high end mattress, ove $1000.  After sleeping on other beds on trips we decided it was really too firm so we got this mattress topper. It is incredible, sleep like a baby, I notice my wife does not move around as much, or make as much noise sleeping, and sleeps soundly.  It has just the right firmness for our backs and creates no pressure points so you sleep longer in one position getting more deep sleep.  We got a King Size, rolled it out and it did not look big enough, don't worry, it takes about an hour to expand so let it sit on the bed before putting the mattress cover and sheets back on it.  I actually "Crave" sleeping in the bed more.  When I rolled it out, and let it puff up, I then took a test ride, fell asleep immediately at 3PM it was sooo comfortable.  I did not notice any smell as reported by others.  I cannot recommend this product enough, and it is a great value.

Update: 5/27/11  We bought my sister a similar topper at Kohl's and it is not the same as ours, is not as firm, we love this topper and cannot say enough about it.  When we sleep on other beds we really know the difference.  On this topper we sleep deeper and wake up refreshed!

This is the perfect answer for us. My sleep has been a much better experience. My husband has said the same thing.

I've waited three years to finally try this pillow. I did not expect it to work. It is amazing. I feel great. My neck pain is gone. Shoulder pain is getting better and I haven't gotten a migraine since I started using it. I got the second firmest one. I thought I would hate it because I am usually unable to sleep on firm or full pillows. I don't understand how it works, but it does! I am getting a set for my mother who is bed ridden. I'm so happy I have sound something that can ease her pain.

We have had this mattress for over 8 months now and it is still extremely comfortable. With one of use at 110 lbs and the other at 250 lbs, you may think it would not recover every morning. It has so far. Every night it feels the same. We did get a plush pillow top mattress cover which added 2-3 inches. We got this in case it was too firm. When it arrived we found the mattress was not too firm, but used the cover anyways. It has been the best sleep I have gotten in as long as I can remember. Price has gone up some since I bought it, but at $665 currently for a King-size, it is still worth it.

NOV 2017 UPDATE:
I have now had this mattress for 3 1/2 years, and it is holding up great. I sleep much better on this than I ever did on a coil-spring mattress, and I am still very happy with it. So far, I have had no issues with permanent depressions, or loss of firmness or shape. Still very comfortable.

ORIGINAL REVIEW:
 This was my first memory foam mattress purchase, so I went with the less expensive option, rather than drop $1000+ on something that I was pretty unfamiliar with.  Turns out, this was a great choice.  I purchased this in May of 2014, and two years later, it is still as comfortable as the first night I slept on it.  I was concerned about reviews mentioning the smell when first unpacked, and there was a slight smell, but it disappeared after a day of letting the mattress unroll and air out.  Over two years, I haven't noticed any change in the firmness or shape of this mattress at all.  I purchased the medium-firm after reading reviews suggesting the firm was too stiff, and while this is comfortable, it is a little softer than I prefer.  I prefer a more solid mattress, so when the time comes to replace it, I will probably go for the firm option.
The brand listed is DreamFoam, but mine was sold through Brooklyn Bedding, and they were great to deal with.  This has been a great mattress and, at less than half the price of the better known brand, it was a great deal.

I bought the 16" lucid with latex because it was the same price as the other lucid that was memory foam only. Its a bit softer on the "pillow top" than many of the memory foam mattresses we tried out, but It didn't take us but a few days to get used to it.
We sleep with a large dog in the bed, and I have restless wife. I sleep right through all the activity because of the reduced motion transfer.
We've been on the mattress for a month, and its been great so far.

There are a few areas I'm not sold on yet.
First, most fitted sheets don't seem to the fit the 16" thickness very well.
2nd, its only been slept on in cooler temps, so if this is a "hot sleeper", I don't know about it yet, but it hasn't been warm enough out yet.
3rd, they say the foam deforms over time. I weigh 220lbs, so not huge, but enough to deform the mattress if its going to happen.
4th. It is made in China. Initial quality is good, but I'm not sure how long lucid will be able to back up their mattress.

In closing though, I'm very happy. I've recommended people on a budget sit on ours. It really doesn't feel too far off the $3,000 tempurpedics, Right now, I would buy this again. Very happy.

Update: 1/14
I've not had this mattress for over 14 months. Its still wonderful. All concerns about build quality, temperature control, and dirt/odor resistance are gone. However, upon writing this review, it is worth noting that that price has gone up from the 700 I paid to 999. However, in my opinion, this is a an excellent mattress. Not an excellent mattress "for the price", but just an excellent mattress.
