SUPER PLUSH FEEL!
Size & Weight I purchased the 4 inch Lucid topper for my 14 inch King Size mattress. It fits well to all 4 corners. The topper is kind of heavy but not impossible to move. According to the box, it weighs 26.85lbs. It will feel heavier because the object is large and the weight is spread over several square inches. To move it, Grip the topper firmly, but with care and you shouldn't get tears or any other issues. Authenticity First, be sure you are buying an Authentic Product from LUCID. It should come in a box marked with the company's name on it, see the images. Likely, some reviews could be showing a blue topper that looks similar to the Lucid Product but it may be a knock off. I've seen some that are light blue like Lucid's, but it isn't the same. It has a knock off name. According to the box, mine was manufactured in Vietnam and came with a booklet and a free mail/envelope opener. ( Should you buy, yours may be manufactured else where ) Packaging & Expansion. The images you see were taken 1 minute after I opening the vacuum bag. I should have taken an image of it in the bag. It was vacuumed down to about 1 inch of uniform thickness. The topper expanded rapidly after opening and it took about 1 minute to fully expand. Again this is a genuine Lucid product. I see of some reporting it taking days or several hours to expand and even having to place it in a higher temp environment for this to occur. My A/C was set at 72dgs and the room temp was the same. Still, it expanded in 1 minute, which is nearly instant. Smell The topper does have a light smell similar to new carpet but it isnt over powering and honestly, after about an hour or so after opening it, I could no longer detect the smell. Feel I chose the 4 inch because I like that " sink in your bed" feel, which can be great for reducing back and neck pain. The 4 inch is super plush. Because the 4 inch is the thickest and softest, you will sink the most. Some will like this and some won't. Some will mention they don't like crawling out of a hole in the bed...honestly I wouldn't want that either so for the best results, I added a plush pillow top sheet cover to mine. This keeps the soft sink feel but allows you to have no trouble getting out of the bed and I couldnt ask for a better combo. IT MADE MY CHEAP 14inch WALMART MATTRESS FEEL LIKE THE SIMMONS BEAUTY REST HOSPITALITY BEDS IN PREMIUM HOTELS! Both of these are breathable and cool so no night sweats! ( this may vary as no two people are the same ) Also if you sleep with a partner, movement on one side of the bed with this topper won't disturb! Final Recommendations I do not recommend buying this topper for completely worn out matresses, or Stomach sleepers unless you have full size body pillows. But if you sleep on your back or sides and you don't want any back pain and you love the sink in feel, then this is your topper. Also be sure to identify your comfort needs BEFORE you buy.

Sooooooo Comfortable
Super comfortable! It is very plush and thick as I did order the 4 inch topper. It did smell a bit when I first opened the package but the smell dissipated after a few hours to a day. It is very high quality and decently durable. I saw some other reviews that said that their topper ripped but I think that was only a problem with the larger sizes such as king and queen as the twin xl one that I ordered did not rip at all and I do roll around a lot in my sleep. I didn’t buy the cover for it so it did slip around but if you but the non slip cover it should be fine.

So Comfortable!
I was hesitant at first because when I opened the box this was clearly expanded. I saw the tear in the plastic but the backside was still vacuum sealed so I kept it. This is the most comfortable topper Ive owned. My Husband and I have slept well and woke up without back pain. I highly recommend this.

Good product, good night's sleep, good value, and poodle approved!
About 14 years ago, we purchased a queen-size memory foam mattress (from Costco). It was our first time using a memory foam mattress, and we liked it a lot. Our next home came furnished with a new king bed, so we bought a 2-inch down-alternative mattress topper. It was inexpensive and adequately comfortable. Our home after that came with two new twin XL mattresses on a common frame (comprising an inexpensive equivalence to a king bed). We continued using our 2-inch down-alternative mattress topper. It finally became lumpy, so it was time to get something new. We saw the Lucid 4-inch memory foam topper and decided to give it a try. We find it to be a good product, providing comfort similar to an entire memory foam mattress (like the one we had originally). This topper even fills the small gap between the two twin mattresses, so that it feels like an actual king mattress. The topper is packaged well, and expanded to its full size in about 36 hours. At that time, the slight odor was gone too. We enclosed the mattresses and the topper in a basic mattress pad, and then put on the bed sheet. Inside a mattress pad and covered by a bed sheet, the topper is a bit less pliant than it is when uncovered, so it feels somewhat less cushy than it does on its own. You may or may not notice the difference, but that's purely subjective. We did not find the difference to be objectionable. Since this product is made in China, I was concerned about the chemical composition of the gas that the mattress gives off when it is new. The reason for my concern about this stems from contaminated Chinese drywall that was used in many homes in my area that were built between 2006 and 2008. The drywall gave off toxic gasses that caused health problems, and caused serious deterioration of copper, thus ruining wiring, air conditioning systems, and jewelry! I contacted Lucid customer support to inquire about this. They assured me that the gas given off by the mattress is harmless, but they were unable (or unwilling) to tell me the chemical composition of the gas. We paid $112.49 for the mattress, but less than a week later, Amazon was selling it for $89.99. At $112.49, this mattress topper is a good value. At $89.99, it's a steal! (By the way, if you do not like the topper and want to return it, keep in mind that after it expands to its full size, the topper will not even come close to fitting in the box in which it came.) Finally, our standard poodle agrees that this topper provides good bedtime comfort, and he approves, as shown in the photo!

I was searching for an alternative to Tempur and Visco Soft, and I finally found it. :) The 7.5 cm thickness is perfect, especially on top of a firmer mattress. Comfortable, supportive, and exactly what I needed.

quick delivery, item exactly as described. Made a huge difference to our very hard rental serviced apartment mattress.
