  • Used this for FIVE YEARS
Size: Full Style: 4 Inch Pattern Name: Topper Only
I got this mattress topper back in June 2019 and I just ordered a replacement today in march of 2024. It held up very well and made every bed I sleep on feel premium and comfortable. I would 100% recommend for anyone looking to add some comfort to an old mattress. It is very soft though so for anyone with back problems I would recommend something thinner. ... show more

  • Best sleep! A true cloud!
Size: King Style: 3 Inch Pattern Name: Topper Only
The media could not be loaded. Sleeping good for about 4 months now. Bought this after a friend ordered and recommended. Saved in cart until prime days and got a great deal- but I would have paid full price after sleeping like a baby now. It’s worth it!! Sitting on top of my Vibe memory foam mattress (also from Amazon). We sleep like angles floating on clouds. If you like firmness this isn’t for you. If you like to sink in and be whole body snuggled- buy this! Everyone likes a different level of firmness- know what you are looking for. For reference id compare this to a cross between a thick memory foam and those squishmello toys kids are crazy about. Soft but also memory foam- see my video. One additional thought- I used to be a stomach sleeper, I know it’s bad and I’ve been told to quit for my backs sake. But since buying this- I never stomach sleep, it’s not comfortable to. I sleep on my side or back. Specs- instructions said to let it “fluff” for 24 hrs. Well I didn’t have that option so I left it fluff for 12 hrs. No problems. Came clean, no bad smell- smelled mildly like new plastic. Foam quality was good day one and still good now. Some reviews had said some things about the foam falling apart- I’d assume that’s from a dog digging in or something wild. There’s no way this would just fall apart. Spills? This would be no fault of the product. Duh it will stain if you don’t clean it. My boyfriend spilt a small bottle of Gatorade on the bed when the dog jumped up. We just used a towel and some spray to help clean this. After it dried, some discoloration but nothing crazy. Size? This IS AN ACCURATE SIZE. True king. I posted pics of what we have happen… because our mattress is in a fabric protector sometimes (not always) it slides by about an inch. Easy fix. When I wash sheets I just readjust and line it up back centered. Doesn’t affect us at all but wanted to share because there were reviewers saying it wasn’t an accurate size for their bed- I’m willing to bet they just don’t have it centered. 10/10 recommend. Have sent this link to many people. ... show more

  • Fantastic
Size: Full Style: 4 Inch Pattern Name: Topper Only
Well I have spent the last week sleeping on this, I do feel that I am sleeping a lot better! My back feel better. So, my personal opinion worth the money! Although at first it did feel a bit firm for how I like my memory foam, but it’s quite comfortable after sleeping. Ordered this because I had surgery and knew I was going to be in bed a lot due to recovery. My memory foam mattress is kinda hard. ... show more

  • 1000000/10
Size: Queen Style: 3 Inch Pattern Name: Topper Only
This is my second Lucid memory foam topper. I moved to a different country so had to get another one. Both times I’ve got the 3”. It’s honestly 100000/10 this makes my back rest really nice. Material feels breathable.It’s firm but it adjusts to your body in the best waaaay. My family loves hanging out in my room because they say my bed is so comfy 😅. Honestly I ALWAYS RECOMMEND this product. ... show more

  • Well..., maybe there IS a God......
Size: King Style: 3 Inch Pattern Name: Topper Only
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. ... show more
