Lucid 4 Inch Memory Foam Mattress Topper, King Size – Cooling Gel Bed Topper – Preassure-Relieving Ultra Plush Feel – Ventilated Breathable Design – CertiPur Certified - Dorm Room Essentials

I’ve been really impressed with this 4-inch memory foam topper. It completely transformed my bed and made it feel so much more comfortable and supportive without having to replace my mattress. The foam is thick and has that perfect balance of softness and support. When you lie down, it slowly molds to your body and feels like you’re sinking into a cloud that gently hugs you in all the right places. It really helps relieve pressure, especially on my shoulders and hips. What I also love is that it doesn’t feel too hot or overly stiff—it stays comfortable through the night and keeps its shape well after use. Every time I get into bed, it feels like an upgrade in sleep quality. Overall, this memory foam topper makes a huge difference. It turns an average mattress into something soft, cozy, and truly relaxing to sleep on.

I purchased the queen sized lavender 3" topper for reference. I bought this item to go on top of our more firm memory foam camper mattress. It is very soft and if it is placed on a hard mattress you may be able to feel the harder mattress below over time, but this topper is still incredible. I also used this on my everyday sleeping mattress and it was a dream! So, I am going to buy another one for my room now. DO NOT force the topper open, let it expand on its own time. If you force it open before it starts to fluff up you may damage the topper, rips in the seams etc.. Mine took about 45 minutes to fluff up before I laid it flat. I put it on my bed and walked away and came back to the room about 45 minutes later and it looked fluffed up. That's when I laid it flat and I let it lay out on my bed all day, that night, and the next day before sleeping on it as well. I used it on my bed for one night before I moved it from inside my house to my camper and put it on the bed, put a mattress protector over it and then put my regular sheets on the bed. I moved it into my camper and put it on my memory foam mattress that is rather firm. This topper isn't very dense so you will pretty much feel the softness immediately when you lay down on it and your body will make an impression. I am 130#'s and my husband is 180#'s, we both slept very well on it during the month we used it out on our adventures. My husband absolutely loves this topper and wants another one for our bedroom. I had a traumatic back injury 10 years ago and I also agree to how comfortable this topper can make your bed. I did feel that after about 8 hours of laying on it during the night (I am a side sleeper) I could feel the mattress below it, but I also think this is because we have an old firm memory foam mattress in our camper. I knew when I purchased it that it wouldn't alleviate that, but I was hoping it would help make it more comfortable and I was right! When I used it in my bedroom I didn't feel the mattress below and I slept in for the first time in years! I'm so happy with my purchase that I am purchasing a second one! PROS: I really like the smell of the topper, it is pretty strong when you first open it, but it goes away within a couple of hours. Now I only smell it if my face is by the topper and it is a very pleasant smell. It helps firmer mattresses become softer and more comfortable. It is a dream on my bedroom mattress that is a hybrid (springs and memory foam on top). It is light weight and I can move it around to different beds if I want by myself. It is exactly the size of my queen mattresses, the same thickness all over, and I didn't have any issues with it moving around and I think this is because I put my mattress protector over it and then my sheets. CONS: The wait for it to be useable is hard because I am an impatient person. It did move around on the bed until I put it under my mattress protector. The smell is pretty strong when you first open the box, but it dissipates in a few hours time. Not sure if this is 100% the toppers fault, but I feel like it makes me sleep hotter during the night and I like to sleep on the cooler side. Overall, I would recommend this to anyone that is looking to add some extra comfort to their mattress whether it is new or used.

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!

The topper looks just like the picture shown. Our bed is years old. The mattress is still in decent condition. It's one the flips over and has a pillow top on both sides. We've always been good about flipping and rotating it. But, time wears on. I have neuropathy and I was noticing that my hands and arms were falling asleep or tingling every morning. I have had to wear braces. Plus my lower back would take a while of creaking to warm up and not be sore. I have one hip that had started to hurt. I'm not getting into the husband's side. We are both healthy and keep in pretty good shape so I just knew some of this was the mattress. Was I ready to spend another $1K or more on a mattress....ummmm....nope! I had slept on a friend's bed who had gotten a memory foam mattress and liked it. Then I started researching the toppers. I have been looking into a topper for months. Figured I would give it a shot. Hopefully sleep better and save a little money. Thank you Prime Day! haha After reading about everything I could and then reading reviews, comparing prices etc, I decided on this. Hallelujah!! I picked this one because it had good reviews on temperature. I run hot so I needed something that wouldn't make me sweat. I liked the bamboo and charcoal features. This came perfectly packaged. Easy to open (provided a razor tool for the plastic) and lay out. There was absolutely NO SMELL. I was worried. I put my face right into it. Nothing. I have a small house so there was no way I was able to stick a king sized topper somewhere for 48 hours, so this only sat for about 14 hours. It did start to expand immediately after being laid out. I already had a pillow mattress cover w/ deep pockets and it fits right over it. I have slept on this for 2 nights so I might be pulling the trigger early on a review, but I will definitely update this if necessary. Night one: I could definitely tell a difference. It was very comfortable. I was worried about too soft or too firm, but like goldilocks, it was just right. It is soft enough that you sink into it, but firm enough that you are not in a hole (if that makes sense). I was not hot at all. Summer is definitely a time to test that out. Night two: I think I liked it even better last night. Just a huge difference. Even lying on it to read. I was comfortable with no aches. Huge difference in the morning. I haven't worn my arm braces and my arms and hands have not had any pins and needles or numbness. My hip has not bothered me and my lower back doesn't feel like I have to oil it up before exercising or just breathing. At this point, I would definitely recommend this topper. I know there are so many out there. My suggestion is don't rush it. Read reviews on and off of Amazon. Going through though, add this one to your list of a possibility. I will add too that I was thinking I would need a 4 inch, but I did read somewhere that someone stated that it feels like you sink further down with a 4inch so I got the 3 and it's perfect for my needs. Sorry so long, but I invested a lot of time into this. haha

Seriously, my prayers have been answered. I only wish I would have thought to invest in this mattress topper while I was pregnant. It might have saved me a huge headache (literally). I've never had much luck with mattresses, but I've never really blamed the mattresses - because I suck at sleeping. Apparently, I'm a contortionist in my sleep and do things with my body that would give little Linda Blair a run for her money. I wake up a million times a night with pains in my head, my neck, my back, my hips, my legs, literally everywhere. However, I've had a friend come over to help with my new baby and I happen to have the same mattress in the guest room that I have in my main bedroom. She brought it up to me one day that her hip and lower back were killing her since sleeping on the mattress in the guest room- even though it is a pretty expensive pillow-top brand. She asked me if I could order her some kind of mattress topper from Amazon and she'd reimburse me. At this point, I had been in so much agony myself that I got two - one for the guest bed and one for mine. And if it weren't for the fact that I only have nightmares, I'd insist that I'm dreaming up this amazing experience with this mattress topper. I mean, I really don't even have words for this thing. I'm not pain free - because, well, it's gonna take a lot of time to undo that kind of damage. But I have noticed a dramatic difference. My body feels so soothingly cradled. I'm not tossing and turning constantly trying to get comfortable. It's just pure bliss. This may sound strange, but it feels like a hug. It does. It really does. Like a hug from the Pillsbury Dough Boy. Some Technical Details: 1) It was very easy to set up. 2) There was only a very faint odor that dissipated almost immediately. 3) I was so desperate to use it that I didn't even wait the full 48 hours as suggested but it seemed to be super plump straight out of the box. The density is perfect for me. 4) It fit absolutely perfectly across my king-sized bed 5) It appears to be of durable quality unlike some toppers I have seen or used in the past that easily shred or discolored. Time will be the ultimate test so I can't 100 percent guarantee this but judging from observation this would appear to be the case. I will update as necessary. 6) It does live up to the claim about not retaining heat and keeping the body a cool and comfortable temperature (which is crucial for a person like me because I practically need to live in an igloo). So yes, I'm very impressed thus far and absolutely I would recommend this to anyone and everyone. I've honestly never been this excited to go to sleep. My fiance loves it and he was a bit upset that I got it in the first place because he loved the mattress the way it was, but now he loves THIS more. And even my little doggie who has become a neurotic mess since my baby was born seems to be a tad more comforted and peaceful sleeping next to me now. Just writing about it makes me want to go upstairs and jump in bed. I'm starting to wonder if they put something inside this thing if you know what I'm talking about, because I'm addicted. Just kidding... Maybe.

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 😊

UPDATED REVIEW 6-6-22 ***************************** I'm leaving my old review below, as for the 2st 4-5 nights, this gel foam topper was the best. But, since I'd been sleeping on a hard as a rock, large yoga mat for weeks prior to receiving the topper (see review for that) & an uncomfortable air mattress for weeks before that... that's probably the reason this topper felt like sleeping on a cloud. After 2+ wks of sleeping on this, I realized it's too soft to offer any support to spine/joints for me. I know others differ, which is why I left my previous review below. I'm a small girl, so I would guess the heavier you are, the less comfortable this will be in the way of offering good sleeping support for any length of time. To be clear, I don't have a mattress. I have cobbled together roll-up yoga mats, varying pieces (as I'll be moving in 6-mos & wanted to carry them with me in my car, rather than renting a trailer to move a mattress or leave another behind), which turned out to be a pricey mistake... if I just shelled out money for the firmer pillow-top, bed-in-a-box mattress I prefer (Ashley, sold her on Amazon at the best price), I wouldn't have the problem of nightly uncomfortable sleep & in fact, it would have cost far, far less. Lesson learned. In any event, after 3-wks, I wake up sore everyday & my spine feels like how a 90-yr old lady's must feel. I'm a side sleeper, so my hip is so sore, I can barely stand up & when I do manage to shimmy all over to actually get off the too-soft topper, I have severe low back pain, sciatica & walk hunched over, which lasts for an hour & I haven't had any of those since a car accident years ago. That's what's scared me the most... I'm afraid the sciatica/hip/back will worsen (it has worsened since day 1, in fact), so since I'm still in the return window, I am returning this topper tomorrow. It's great as a temporary bed, whether alone on a floor or placed on a bed frame. It's very bulky, but you could roll it up to place in a closet, if you have adequate room, although, you do need to let it puff up for 48-hrs once you unroll it again... given that, it's probably not the best choice as a guest bed, but your guests will sleep like babies for 3-4 nights. Kids could also sleep comfortably on it, especially if they're light weight. Note: Older folks or those with injuries will have a tough time getting off of it alone, cuz you do sink into it after hours of lying or sitting on it & since it's soft, you have no traction underneath as an aide in pushing yourself up. I'm a small girl & I struggle to find my way to the edge every morning. I have to roll around like John Belushi in Animal House doing the worm dance to find the edge, then roll out of bed. I've grown to really hate it & regret buying it. I've downgraded from 5* to 3 out of 5. It is comfortable, just not for very long. It is good quality, just not what I need. PREVIOUS REVIEW, WHEN I'D JUST RECEIVED THE TOPPER ******************************************************************* Best sleep ever. I resisted buying this as I've slept on guest beds with inches of corrugated foam toppers, which were so horrible, after day 2 of one 2-wk visit, I opted to sleep on the floor, much to my host's chagrin. I sunk into it like a victim from a horror film, it was so hot I was covered in sweat & felt liked I'd slept in a sauna, I kept waking up all night long & was so sunken in, getting out of a cartoonish bed of sponge felt like I needed a crane or 2 bodybuilder to assist me... & I'm a small girl. But, if you look at other reviews of mine, I'll briefly say that I needed a makeshift nest as I'm only in this apt in the middle of America for 6-mos & don't want to buy a mattress to leave behind. I travel & move often, so I've had to discard 6 mattresses in 5-yrs & my wallet is sparking curse words at me. My current set up is a full size, 3" thick, roll up, yoga mat, very well made, contents don't shift, but it's hard as a rock & not comfortable enough for side sleepers or for longer than 1-2 nights (see my review). To be fair, it's not meant to be a bed. No worries, I thought if it didn't work for sleeping, I could use it for exercise & I will once I move again. So, after 2 nights of feeling like I was sleeping on a hardwood floor, I then bought a dizzying array of various mattress pads, all claiming to be 4" thick, soft, fluffy as sleeping on a cloud... utter lies! Had to return all of them, even the ones in the $175 range... they all flattened & offered no cushioning. I finally settled on using 2 because I realized that not one of them offers enough cushioning. (To that end, one of the best & cheapest is good ol' Amazon basics.) Still, 2 mattress pads/toppers (feathers & fiber fill) on top of a hard as a rock mat, is not quite enough. Bought this gel foam topper after searching for wks. It was the best decision. It offers great cushioning, but I don't sink down to ridiculous proportions. A tip... let it lie unused for 48-hrs as the directions suggest. I was anxious to use it more quickly, but when I would lie down on it, I'd sink right in... it needs to puff up, firm up & settle & it does. I can't rave enough about it. Since I've been sleeping on it, I don't move around as much, I fall asleep right away, sleep soundly & don't wake up with all over body pain. Haven't had that in a long time. It's a wonderful product & worth every penny of the $100 I didn't want to spend... it was well worth it. 5* out of 5. A great product!!!

This has been probably one of the best products I’ve purchased through Amazon! SO comfortable and tames down my aches, pains and muscle stiffness throughout the night for better sleep and way less pain the next morning. It does make it harder to turn in bed, and I do get a little warm from laying on it (not extreme warmth), but the benefits are worth it. Others foams I’ve tried aren’t even close to the comfort I get from this product.

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.

super soft

Its very comfortable feels like a old fashion feather bed, very soft like a feather pillow

below one star.

I love it its so comfy but, 1 foot too big worth wise but cut it down and it fits well
