Review: 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.
Review: 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.

## Questions & Answers

**Q: Why should I get a topper?**
A: Whenever your mattress is ready for a refresh, but your wallet isn’t, it’s time for a topper. Or if you wish your mattress is softer, or if you are in a dorm or renting—a topper is a great solution! Upgrade your bed without the hassle.

**Q: Will my topper come in a box?**
A: Yes! We make it easy. Lucid memory foam toppers come compressed and rolled in a box, are easy to move, and set up in seconds. Just unbox it and let it decompress for 24 to 72 hours before sleeping on it.

**Q: What are the benefits of gel infusions?**
A: Gel infusions in memory foam help regulate temperature, so it sleeps cooler than traditional memory foam.

**Q: What height topper should I get?**
A: The 2-inch profile adds a soft layer of support to your mattress. The 3-inch profile is very plush and adds even more comfort. The 4-inch profile is almost like a mini mattress, with an extra deep, plush, sink-in feel.

### ⭐⭐⭐⭐⭐ So Comfortable!
*by A***Y on January 15, 2026*

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.
