4 Inch Cooling Gel Memory Foam Mattress Topper, Ventilated, King Size

Well my mom came to me and asked one visit if I could find her a good 4 inch mattress topper for 150.00 or less and since a latex topper was out of the question due to her budget, I immediately thought of Lucid. I don’t actually have a Lucid topper, I have a different brand but when I was searching for my own topper a few years back, I almost went with Lucid because they have a metric ton of reviews and their rating is high and very few of them are negative giving how many purchases there have been. Well let me tell you, I’ve been hearing about this topper every morning for two days. My mom set it up on her bed to let it inflate and expand in the morning and she called me to tell me that half the day later it looked great. She ended up sleeping on it that night and she called raving the next morning to tell me how much she loved it and that she’s never slept better and that she should have ordered one years ago. She said she absolutely I didn’t want to get out of bed and that she couldn’t wait to go back to bed. Well she just called me again this morning, morning too, and you know what she said? “They’re right you really should wait a full 24 hours before sleeping on it. Then she began to tell me how how there is something about this mattress topper. She just can’t explain it, can’t put into words and that night two was even BETTER than night one. “Thank you thank thank you you are the best daughter EVER!!” “You knew exactly what to get me, this is perfect!!” “It”’s so soft and so supportive, it is such a dream!!” Seriously she’s been raving about this topper so much that I absolutely plan on ordering another one for myself lol. Oh let me clarify her mattress situation. She had a mattress that she had put in storage probably 10 years ago. She barely used it. Well she has been using the mattress for a few years and had gotten a topper for a different mattress maybe 5 or 6 years ago. When she moved she brought out the old barely used mattress and was using the topper she had been using but that topper finally broke down and had a dip in it. Her mattress may be fairly unused but it’s old. Kind of like buying a basic smartphone with chintzy features. Sure the device might be brand new but the tech inside is from the electronic Stone Age. That’s her mattress. In the world of mattresses, it’s old tech LOL. This topper and a mattress cover I got to go with, brought that mattress into 2022. She absolutely adores it, so much so that I will be getting one to put on top of my mattress even though I have a 3 inch latex mattress topper. I want to experience “THE DREAM” my mom has been raving about for two days. So not only do I recommend it to you, I recommend it to myself! Just be sure to lay it out and give it a full 24 hours to rise. It will look like a flat lumpy pancake when it first comes out the package, believe me, it fills out to fabulous awesomeness after 24 hours.

Perfect! This is plush and sooooooo comfortable! It cushions my body perfectly. This topper is supportive and plush allowing for a great sleep. Thank you!

Let me start off by saying this isn't a paid review. Memory foam's quality isn't just reliant on density. The measure of density of memory foam gives it a Ultra Plush/Plush/Medium Plush/Medium/Medium Firm/Firm/Extra Firm feel. In order for memory foam to BE plush, it has to be low density. The reason Tempur-Pedic doesn't offer low density memory foam (Tempur-ES 4.1 LB Foam & Original Tempur 5.3 LB Foam) is because they distinguish themselves that way. I've used Tempur-Topper Supreme (3" Tempur Original 5.3LB Memory Foam), and it's super high quality, but that Topper is meant for people who like firm mattresses, and I can say the same thing about the 3" Tempur-ES Memory Foam. I've flipped between this memory foam topper, and a Tempur-ES topper. The Tempur-ES is nice, and you can move around easier, but I never feel like I'm being cushioned and like I'm relaxed. You sink in to the Lucid 4" topper, and my body physically relaxes, and I feel cushioned. I wouldn't even go as far to say the Lucid 4" topper is plush, but in order to be a comfortable foam, you will have to sink in quite a bit, or else you're just laying on expensive concrete. Memory Foam is meant to be inexpensive - Memory Foam is cheap to make as they're basically just made of fossil fuels. Don't judge this topper by the price. I first tried a 3" Memory Foam Topper here on Amazon, since the topper had like a 4.9/5 on 100+ reviews, but I don't think that topper was memory foam, and was just basic polyurethane foam. The memory foam had no squishy feeling, and the imprint recovery was almost instant. The Lucid 4" Topper has a fairly slow recovery from imprint time given the Lucid Memory Foam's density. My parents back pains got better when I got them the 4" Lucid Topper. If you're a normal person, and you keep an open mind, then this Lucid 4" Memory Foam Topper is the best thing to make you sleep extra deeper, and sleep longer period or times. I went back to the Tempur-ES topper for 3 months, and that was the dumbest decision I've made in the past few years. My body oozes with relaxation and comfort on the Lucid 4" Topper now, of which never has happened w/ my Tempur-ES topper. Once you get the 4" Lucid Topper, be prepared to be hard to move around if you want to flip over in the middle of the night, but I flip positions 60-70% less w/ the Lucid Topper compared to the Tempurpedic-ES memory foam topper. I use the Lucid King Pillow hybrid as a pillow, the Lucid body pillow I hold on to w/ my arms when I lay on my side, and the basic Lucid memory foam pillow for in between my legs. The side sleep system I use is the best way to sleep. I do hear the Serta Perfect Sleep Luminous Plush Pillow Top is nice, but I can't imagine anything being more comfortable than the Lucid 4" Topper. Enjoy! -Andy R.

Loving the comfort sleep I get every night. Only issue is how often it moves around especially when I wake up in the morning. I frequently need to move it back into position at least once I week. I have even tried to get a grip thing for mattress toppers to put underneath but it didn’t work.

product was packaged well. Set topper out on a flat surface to let it get to proper size. I purchased the 4" topper. it got to size very quickly. seems to be of very good quality. this is exactly what I was looking for, made the bed soft and comfortable.

This is the second memory foam topper i got and I am writing a review in case it helps someone. Because buying big bulky things and returning them is a pain in the butt so maybe this can help you in your buying decision. I am hunting for a topper a very hard, awful futon mattress that was advertised as 8" but was actually 3". I should have returned it right away but didnt' want to deal with return hassle (I learned my lesson now and regret that decision so much). I plan to chuck the whole futon in a year or two so I don't want to buy a new matress and am just looking for a topper to make it comfortable. A few weeks ago I got the linenspa 2" topper, and people wrote in reviews it was like sleeping on a cloud. I got it and was like what cloud? A concrete cloud? it was hard. Old me would have just suffered in silence, worried about the return process, but new me is like stop keeping things you don't love. And sleep is important. Returned that one, got this one in 4". I am 210 pounds now and 5'8 (gained weight post-Covid), an average looking albeit slightly tall woman, a size 14 hourglass (not apple) shape. My heaviest parts, like most people I guess are my hips/waist area. I am a side sleeper who cannot sleep on her back no matter what. THis grew to 4" with an hour, but I let it air out for over a day. i had chatted with lucid and they said waiting 2 days wasn't necessary. Cool! I put it on my bed (*good tip, btw, is I only put the fitted sheet over the topper, not the topper + mattress. so easy to make the bed) and tried to sleep in that night. The following happened each and every night I tried to sleep on it (i tested it for 3 nights): Sleeping on my side, my hips sunk down dramatically. Not all the way down to the mattress below it, but down significantly (I'd guess 2"?). Your body is absolutely not evenly supported (may be different if youre a back sleeper). Imagine your body jut being misaligned all night bc only your hips are sinking into a pit, but the rest of you is not sinking in. When I turned on my back I didnt seem to sink much at all but i just cannot sleep on my back. I feel like my muscles were fighting all night to just keep my body somewhat aligned and woke up feeling mildly like my muscles had been working all night, and not in a good way. I was not rested at all. Your spine, neck etc are supposed to be aligned when you sleep. With this topper, that is absolutely impossible at least for my body (and later, my husband's too, you'll see.) this happened each night (I did give it a few nights' test to give it a chance to see if anythng would change, before I unequivocally decided I need to get this out of the house.) I also woke up each night sweating. Hot. And When I wanted to get out of the bed to go to the bathroom, I had to like catapult myself out because I had sunken in. And if i wanted to flip from my left to right side, again, had to catapult. The absolute worst part is, I have felt completely dizzy (i put dizzy and dizziness in the headline so if anyone searches those words in reviews, like i did last night, it would show up) with my head spinning and like an electric shooting sensation in my right leg (edit/update: when i wrote the reivew, i hadnt returned it yet. i returned this i think over a week ago and still am having massive problems with my right leg which only started when i used this foam. i am now convinced i have a pinched nerve from this topper and am going to see a neurologist. the diziness ended the morning after we boxed this up to return it, but my leg issue persists- it's now weak, there's an electric shooting sensation, knee slightly bucking etc. ive never had a pinched nerve before but i looked it up and the symptoms match up) i have been dizzy only since I started using this to the point where I could not fuction rightly during the day. Felt crazy lightheighted and unable to focus, to the point where I was searching like mad last night "dizziness and memory foam" - turns out other people have reported this issue with memory foam in general. Look it up. Some people may not be as sensitive. I'm not a "everything must be natural" type but maybe i'll become one after this experience. (update: we packed it up for return after 3 days of using it and feeling dizzy - the morning after boxing it up, the dizziness was gone and has not returned.) My husband crawled into bed with me for a few minutes and we weigh about the same, so when our bodies were both sunken in at the same time, it wasnt as bad as when I was alone in it, with the matress sunken in all around me like i was in a sandpit. But i often sleep alone bc I snore :-) Last night he slept it in alone to test, and he didnt sleep all night. He sunk in too much and just couldnt sleep. He is about 5'11 205 pounds. That was good to know. I was going to return it anyway, whether he liked it or not, bc apparently my body can't handle memory foam at all, I cant let my body be dizzy and have weird neurological symptoms. But he woke up this morning and said "i dont like it. I couldn't sleep all night." I said why? He said he was sinking. But he was delirious from no sleep and went into the other zinus comofrtable bed to pass out, so I didn't get more info out of him. So I am done with memory foam for life and am going to line the top of my mattress with many, many blankets, if that doesn't work, I will try latex or wool. (edit: i tried topping my crappy mattress with many blankets and that didn't work. too hard and painful. next im going to try sheepskin and if that fails, latex.) Maybe you will have a different experience, if you're a back sleeper etc. I have read this memory foam is not high density so it's not supportive. Ive read some people love that sunken in feeling but I would caution, if only certain body parts or sinking in, it is really not good to spend 1/3 of your life in a misaligned position. I watch youtube videos for side sleepers and physical therapists and docs talk about the importance aligning our neck, shoulders, hips, and knees while youre laying down, the point of strategic pillow placement to make sure everything is aligned. This memory foam is not only not conducive to that, but actively hurts my alignment. Lastly, the return issue. I havent hit the return button yet but no mater how difficult it is to return, if you dont like something, you dont need to chuck it or live with it, aslong as you are in the return window. My husband and I will smoosh i down and roll it up and if it doesnt fit, will buy a bigger box and amazon can refund us for the box, but i bet it will fit in the original box. (update, it did. return process was great!!) Sleep is way to important to just "suck it up" - and it seems as though it is common for people to hav to try a few different toppers to find the one that is right for them (do you want 2,3,or 4"? latex? memory foam? wool? featherbed? soft, medium or hard?). It would be best to get a mattress that doesnt need a topper in the first place (I still love my zinus 10" we have in the other room!) but if youre like me with a weird matress situation I understad your plight. I hope this review helps someone. i know it's a hassle for both buyer and seller to mail and return these big bulky things so im trying to help people make decisions.

I was very hesitant to order this mattress topper, because of all the horrible reviews here on Amazon of the rips and tears that were occurring. However, the Lucid Mattress Toppers had INCREDIBLE reviews elsewhere, so I gave it a shot. Like someone else in the reviews here mentioned, I was careful as all get out with the unpacking process. I got it out of the box, carefully clipped off the plastic, and then let it SIT on its own for hours. From the looks of it, it wasn't moving AT ALL, but after letting it sit for the first hour or two, I came back into the room and saw that it was in fact, slowly expanding and unrolling itself. I got the whole thing expanding with NO rips or tears. I got a Twin XL because of the fact that, my husband and I have a Sleep Number Bed (split top king), and he has NO problem with the bed (and usually sleeps hot, thus he's wary of any topper). For me, it was still just too firm, no matter what I did to my sleep number. From doing research all over the internet, I learned that some people just need that memory foam type support to feel comfortable. On the sleep number bed without the topper I would wake up with a stiff / sore back EVERY morning. Before sleep number we tried Purple, and that was even worse! My shoulder hurt every morning and occasionally my whole arm would go numb. GREAT mattress, my husband loved that one too (which, he's a hard sell, he's had back problems all his life), however I just needed that extra cushion to be comfortable. Finally I did some research, found the Lucid Toppers, went for the thickest topper, and I couldn't be happier! Last night was a DREAM. The BEST part was, even though this topper is 4 inches thick, my existing sleep number mattress protector and sheet set ACTUALLY fit PERFECTLY over the topper! No extra purchases required! Though I'm a side sleeper, when I first crawled in I felt SO comfortable on my back I thought I may not even need to sleep on my side! One other interesting thing I noticed. Because this topper cradles you SO perfectly and snuggly, if you switch positions, you feel the original "shape" that was formed around you from the previous position. I noticed it probably took about 20-30 seconds for the topper to relax those areas and reform around you in the new position. So, not a big deal at all. Honestly, I think that speaks a lot to its "firmness." Something less firm, wouldn't hold your shape as well. I was worried that that level of "firmness" would still cause me to have back pain or stiffness in the morning, but for the first time in a long time, I woke up with NO back pain. SO happy! Can't recommend this enough, just be very PATIENT and GENTLE when unpacking this mattress topper!

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!!!

super soft

Diff from others review... Ordered on thur get on Friday by amazon prime.... Find it quite comfortable.....not warm...

We logged a return on the same day we received it. It was way to soft for our bed and actually made our bed feel worse than without the topper.
