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: OUTSTANDING CUSTOMER SERVICE AND PRODUCTS!!! - Absolutely totally impressed by Lucid’s customer service team!! Over the last 10 years or so, I have purchased 3, 4” toppers for my bed and 2 or 3 other mattress toppers (3” I believe)for other family members beds in my home. We have good mattresses, but the best way I have found to make them last COMFORTABLY longer is to put a memory foam mattress topper on them - As well as the fact that there is nothing better for a GREAT NIGHTS SLEEP than crawling and then up into a soft, comfy “feeling like you are sleeping on 12” of goose down comforters “ bed. Lucids’s 4” memory foam mattress does just that- makes your bed feel soft and warm and comfy a just as if you were sleeping on 12” of Goose down comforters! (Saying it’s like sleeping on a soft billowy cloud would be inaccurate- you’d fall through a soft billowy cloud & hit the ground like a brick. THAT doesn’t sound comfortable in the least!! 😂😂) So, if you like sleeping on a soft bed, the 4” is perfect!! So why is Lucid’s customer service so amazing? Well, just like every single other product in the world, occasionally one of those products will be defective or something just not right with it. It happens. No matter how great & amazing a company is, it’s pure naivety to believe that they will never ever have some sort of problem with one of the hundreds of thousands of individual products they sell. I don’t mean that every single one of a product they sell will have a problem, I am saying that 1 of the hundred thousands of one specific item will come off the factory floor as defective. In the situation I am referring to, that one item out of hundreds of thousands, happened to be the most recent of 3 of the 4” toppers I have purchased from Lucid. Building a great reputation for selling great products in various shapes and sizes is one thing. How your customer service department handles a situation when a customer contacts them saying that they are having problems with one of their products because that item is defective - THAT is how a company KEEPS their well earned great reputation. In full disclosure, I did have to contact them twice, but I honestly think that the first time I either put in the wrong reply email or the message portal on their website was not working properly- which honestly, with 99% of message portals and there being people writing about various things- compliments, curiosity and complaints as well as on occasion (yes it happens) competitors spamming message portals in an attempt to bog down customer service in order to make the department look ineffective, I personally think it’s better to just use the company’s customer service/information email, making sure that you write a brief description of your reason for contacting them IN ALL CAPS SO THAT THEY SEE IT PLAIN AS DAY! (Just a little advice from someone who has purchased far too many products online lol I am getting better at not doing that 😂😂 Anyways, customer service was amazing and went above and beyond. I emailed them explaining the problem, they wrote back requesting a couple pictures so they could see what I was explaining and to pass on those pictures to product quality control and then a reply stating that they had shipped me a replacement at zero cost to me. All within 3 days! Honestly, if I had sent pictures with my first email , it most likely would’ve been taken care of in one day, so the extra two days are on me! Thank you Lucid!! You have gained a loyal customer 😊

## 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.

### ⭐ Lacks support
*by K***R on November 28, 2022*

I’ve been using the topper for about a month now. I purchased this topper because my Euro plush pillow top mattress is nearing the end of it’s lifespan and I’d been waking up each morning with severe aches and pains. I prefer a softer, conforming mattress which is why I choose this topper. I am primarily a stomach sleeper and I occasionally sleep on my sides. Here are my observations in relation to this topper: 1. The first couple of weeks the topper was comfortable and provided a restful night’s sleep if I slept on my back. By week 3, I started noticing that the foam was not retaining it’s original shape and I was feeling even less support in my lower back and hip region, along with my neck and upper back area. 2. The foam doesn’t distribute your weight evenly, my hips sink too deeply which makes this topper unsuitable for stomach or side sleepers. I have to add in pillows to balance out my posture and take the pressure off of my lower back. 3. The topper is not super soft/plush, it’s more so in the firmer side but with the added support. All in all, I am still waking up with back and neck pain after purchasing this topper.
