Great topper - solved our problem
351479
This is a great topper. We needed something to add some contoured support to a nice 10 yo  latex mattress that had a thin, broken-down polyurethane foam comfort layer. The bed by itself had almost enough give, but not in the right spots. As a result, it felt too firm and we were waking up with back and hip soreness. This topper has resolved the morning discomfort and has just the right amount of softness and density to avoid the hammock effect while also relieving the pressure points. We weigh between 160 and 170 (well-distributed) each.

The first night, we tried coupling it with another very low density (2 lb) 2 inch memory foam topper we already had, and while it felt pretty cosy, having 4 inches of sinking potential caused some aches and pains the next morning. The 2 inches of high density is perfect.

This topper combined with sticking some older flattened pillows underneath the middle of the mattress to counter the sag has made it feel like a brand new bed.

This topper was PERFECT for the hospital bed we have in Dad's room. It fit as if it was made for such a bed, and the comfort is superior!! My daughter now wants this for her twin bed, so I will likely be purchasing a second one.

We needed a solution for my in-laws who had a fence that allowed our dog to sneak through to visit neighboring dogs.  This product was the perfect answer, and doesn't both the dog in the slightest.  I think it took about 2 minutes for him to get comfy with it... now I think he enjoys it as he tends to use it as a pillow!  Well made, perfect for our needs.

This has made our bed comfortable again.  We used to wake up with back and joint pain.  The first morning after sleeping on it, we woke up refreshed, and without the usual aches and pains.  I surprised my spouse with this topper after investigating many others.  We unwrapped the shrink packaging, and it unrolled to its full size. We immediately put it on the bed, it fit perfectly on our Cal-King mattress, and it literally felt like we were on a cloud.  There wasn't much chemical smell, and in a couple days we didn't notice it at all.  This has been a great investment, and prevented having to purchase an entire new mattress for thousands of dollars.  I am a hot sleeper typically, and this hasn't added any additional heat for me.  We have pets, so we protected it from pet stains with this mattress protector, which has worked wonderfully: https://www.amazon.com/gp/product/B006MV7WIO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Shipping packaging problems must have been resolved because there were no small plastic chips that flew around when package was being opened ... just wrapping paper.  No problems experienced with packaging or odor as some comments suggested. Also, did  not take days for mattress topper to lie flat on the bed.  It did this almost as soon as I placed it on top of my mattress.  I did, however, let it air out for 24 hours, just to be on safe side.  I have been sleeping longer, uninterrupted hours since using this mattress topper.  Am very satisfied with it.  2" seems to be just enough.  Previously, I was  having leg and knee cramps and waking up with a stiff neck.  With this mattress topper, that experience is  now minimal, which is a blessing.

Love our new Lucid 3-inch Gel Memory Foam Mattress Topper! I have numerous back problems getting a full nights sleep. This memory foam topper fills the bill for a comfortable and restful sleep. We found that it did not have any odor when we unpacked it and couldn't wait for the 48 hours to end so we could make up the bed. Great Buy!

When covered by a quilted mattress pad, this topper made the bed much more comfortable. It is sized perfectly and does not shift position. I am very satisfied with it.

Love It. We spent a lot of money for a new mattress. Wish instead we had just bought this topper. Our mattress purchased was too soft and hurt our backs  so we bought this to get a more firm top. It did the job.

I BOUGHT THIS TOPPER 1 1/2 YEARS AGO AND IT IS JUST LIKE IT WAS THE DAY I BOUGHT IT.  I LOVE THIS TOPPER AND I WOULD BUY IT AGAIN!!  MY HUSBAND IS NOT A SMALL MAN AND HE CAN RUIN A TOPPER FAST. THIS ONE HAS LASTED WELL!  AS FAR AS COOLING I DONT REALLY SEE ANY DIFFERENCE.  I DONT MIND BECAUSE I SLEEP SO WELL.  THIS IS ALSO GREAT FOR SIDE SLEEPERS.  I WOULD HIGHLY RECOMMEND IT.

This mattress pad did the trick.  We had a cheap king size mattress, and had a 4 inch topper that really helped but seemed too soft.  I thought before i decided to purchase a new mattress (since we only stay during winter months) I would just give this mattress pad a try.  it worked just fine.  It fit right over the existing mattress and also the topper.  Works great...and solved my problem.  very happy :)

I purchased this topper for a queen size medium grade mattress set. This works perfectly to give the bed the extra softness to make it more comfortable for all sleeping positions. It did have a slight odor but I just let it lay open and air out for a day. I'd recommend a fitted sheet made for thicker mattresses to accommodate the additional thickness. I'd definitely purchase this topper again.

I love this mattress topper. I basically like to pretend I sleep on clouds (we have a pillow top mattress plus this 4 inch topper). It's very comfortable, and you can sleep for what feels like days on it. My only issue is that if you (or two people) sleep in the middle of the bed, it bows up on the sides so you feel stuck in the middle of the bed and have to wiggle your way to the side of the bed at times. I had to get a deep mattress pad in order to try to combat this, and it's helped but still seems to be a bit of a problem. That's the only reason I took off a star... Ultimately, I love this topper.

Hubby and I bought a used Sleep Number Bed on Craigslist 2 months ago.  We gave up our wonderful waterbed, because it was too much maintenance.  We had it for 9 yrs. We tried to find our sweet number on our sleep number bed, but just couldn't find it.  The bed is comfortable, but just not what we thought it would be like.  We bought the Lucid Gel Topper 2.5 in. and we found our sweet number.  We love our mattress topper and our sleep number bed!  The topper was completely expanded in 5-6 hrs.  We placed the topper on the mattress, covered the mattress and topper with a mattress cover and the fitted sheet.  We never had any problems with any odors.  We got the gel topper to help with heat issues, but last night it 34 degrees at our house.  So, I can't make any statements concerning the coolness of the gel.  FYI, my number is 40.

LOOOVE THIS MATTRESS TOPPER. My fiance and I noticed that we were both tossing and turning, finding it hard to get comfortable, and waking up with aches and pains lately. So rather than buying a new mattress (which we've only had for under a year) I thought it woukd be a good idea to buy a memory foam mattress topper. However this one caught my eye and the reviews were good so we chose this one. Ive only had it for a week and we're sleeping better than ever. This is a great product

I'm very pleased with this topper. I purchased it for the bed in my spare bedroom, which has a fairly thin mattress. Reading the reviews, I was worried this wouldn't be quite up to the task, but it feels wonderful. I even slept on it a couple of nights just to enjoy it. I'm not giving it 5 stars because it wasn't 4 inches; it's more like 3.6". But it still does the job, and I won't have to be embarrassed to have company sleep on that bed anymore.

This topper fixed my back! After months of sleeping on a very firm queen mattress my wife got, we decided to try a topper to help with the back issues I was having.

After using this topper, I can officially say the mornings of waking up with a tight/stiff back are long gone. I wake up feeling more rested even if I don't get as many hours of sleep too!

Overall a great product!
