When my old non gel infused memory foam mattress topper started to crease I decided to replace it. I replaced it with this one and although this is a great mattress topper it's not as comfortable as the non gel infused one I used to have. I sometimes wake up with back pains. I'm moving this one to the guest room bed.

It was great when I first purchased it
Since the height it makes it too soft
Instead of supporting my back
My back curves and hurt
It will be perfect for someone that just want a better mattress

This is pretty comfortable,  but it is thick and squishy.  I put it on my tempurpedic bed (which is ridiculous considering how stupid expensive the bed was), because the bed was making my hips hurt so bad.  I am sleeping better though.  I wouldn't say this topper is cool though.  You really sink into it, so there isn't much room for air circulation.  You seem to get stuck in it, but I don't mind.... I am 4 months pregnant though,  so we'll see how much I like it once I'm huge.  I had problems with my sciatic nerves with my first child,  so I'm hoping this one is better and the topper helps with some of the pain

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.

I definitely think this topper has helped but I would've preferred it to be a bit firmer. I bought it to go on top of a mattress in a furnished apartment that a previous tenant had created an indentation in one side. I still find myself sinking in to that hole. All in all it's better than without it.

Mixed feelings on this topper...

Pros:
- Takes a very firm bed and makes it feel like it costs $1,000s more.
- I put this on the cheapest Sleepnumber / Sleep Number bed (C2) and it make it feel better than models costing twice as much. Adjustable air underneath is very helpful.

Cons:
- If you have a softer mattress this might make the bed feel too soft
- Better for heavier people (>200lbs) at this thickness. In the end I would have preferred a 1" or 2" as my wife is just over 100lbs and this is too thick and ends up causing back issues. (even with the sleep number bed at 100%)
- THE BIGGEST CON is the fact that I took it off the bed and folded it to try something thinner one night. The next morning the topper had torn itself into 4 pieces where it was folded just on its own weight! I can't see this thing surviving any sort of move to a new house / apartment etc.

All in all if you know you need a 3" topper and you don't plan on moving it around then you should be OK. Otherwise, roll the dice.

UPDATE:

I contacted the mfgr and they sent a n/c warranty replacement. Thanks customer service. The topper itself still seems brittle and prone to tearing but for now its whole and on my mattress.

I just replaced our 20-year old mattress and replacing an old Sleep Innovations memory foam mattress topper too.(The old Sleep Innovations brand is about 10 years old).  We also have another Sleep Innovations mattress topper on another bed now and that's about 8 years old.  It still feels great; our teenager doesn't complain and still sleeps well on it!

This is the first time I ordered a 3" thick Sleep Innovations Memory Foam Mattress Topper.  It was delivered the next day and immediately I opened it so I can unroll and let it reshape and also get some of that foam smell out.  To my surprise, the smell was very minimal compared to other brands I have bought years ago, and returned because of the "off gassing".  By about 10pm that evening, we put the foam mattress topper on top of the bed and proceeded to add the bed sheets, etc.

I actually LOVED the way the 3" felt and I slept like a baby and woke up with a 50% reduction from low my low back and hip pain.  I truly loved this. It felt so soft and yet supported and not pinching on my nerves! However, my husband's experience was completely negative.  He woke up with so much pain that he can barely walk the next day due to aches and pain in his back.  I thought maybe he didn't sleep "right" and asked him to give it another night.  My nice guy slept on it the next night but by 3am, he got out of bed and slept on the couch! He was so uncomfortable and continued to complain about the aches and pain.

In conclusion, I think this is a very good product, since we have owned the 2" version for many, many years.  Unfortunately, the 3" thickness made him miserable for two nights.  Lately, there has been so much hype about how foam mattress toppers are best at 3".  I can now disagree with that.  I think it all depends on the person.  Although I had absolutely no problems with this product, my husband did.  It would be nice if I could slice it in half so I can have my memory foam topper, but that would be silly and unfortunately, we had to return it.  For now, we are sleeping on our new mattress "naked", meaning with no foam topper.

I really liked it when I first purchased it, but after about 10 months, it doesn't seem as soft as it did before.  It doesn't comform to my pressure spots (like shoulder & hip) like it used to.  I have always had a waterproof mattress protector on it.  It's still better than my old mattress though.  I'm just worried that the softer layer on top is breaking down.

We were so excited because we had stayed at a hotel and had slept amazingly well. We learned they had something similar to this on the mattress. I ordered one to surprise my bf for xmas. We were excited to sleep on it. It wasn't as plush or even as noticeable as I thought it would be but it did make a difference. However, we learned that we actually slept worst than when we didn't have it. I suggested removing it from mattress and wow, we actually slept well without it. Sooooo it's back in its bag in the closet. I'm not saying it's a bad product, it is good quality, it just didn't work for us. We learned we like more firm mattresses I suppose lol

I bought this to make the mattress more comfortable in our travel trailer. It helped considerably. Even though it's not as comfortable as the bed at home, it's probably due more to the mattress than the mattress topper.

Like most memory foam toppers this one is losing some of its buoyancy after 3 months, but it is a lot more comfortable to have it on the old frame than not have it.  I have not yet found the perfect solution

Its comfortable but not as comfortable as I thought it would be based on the reviews. I don't not like it, I sleep through the night comfortably, it does its job, It was a great price considering the convience as well, and I don't wake up with any pain though and Im very suprised because i get back pain pretty easily. I was between 3 and 4 stars but went with 4 for those reasons. When I wake up Im not like wow that was the best sleep of my life but Im also pretty well rested. Its Definetly a firm mattress more than anything else. I would say 7/10 on the firm scale...I sink in just barely and I prefer a more medium mattress. Im honestly suprised at how good these reviews are based on the firmness...I guess the majority of people like firm mattresses? Simply put, If It wasn't impossible to put back in the box I would probably return it but I don't hate it and I opted to buy a mattress topper to make it softer instead.

I do like having this addition to our mattress, and I think it helps having the body contour rather than I firm mattress,  however isn't as great as I was hoping

I purchased this same pillow 5-6 years ago so it was time for new ones.  However, they are not quite as plump as the original pillows I purchased.  I have been sleeping on the new one about a month now and it seems to flatten out a little more than I would like but I still like the pillow and will use it.

When I first sit on my bed I love the way it feels. It quickly sinks in and is not as comfortable. I also thought it would help with covering the indents from where we sleep on our pillow top mattress but even when it is on you can see the dips.

I don't find this mattress to be the most comfortable sure mattress I've slept on.

It's expensive but not what I thought it would be. It's kind of awkward to lie on. No neck problems though. It's not as good as my last one but this one should last longer, which I'm sure that's a good thing since I'm still trying to get used to it.
