  • Support is soft, so might be okay for some, not me...
Size: Full Style: Topper Only
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!!! ... show more

  • My bed has been transformed
Size: Queen Style: Topper Only
I was having insomnia due to a new medication. It was so awful! Then I house sat and the bed was so comfortable I fell right asleep 😴- they had the topper and it was so soft and comfortable, you melt into the bed. So I had to get one and since I did I haven’t had a sleepless night! Once it was unwrapped and coming to its form on the bed you could clearly see it was true the the description of 4inches. It actually covered up the creaking my bed use to make, it’s now silent. It’s hard to move once it’s in place so it’s very stable and you can tell when you lay on it and sink down it had a lot of breathability. I recommend this to anyone who is having sleep issues, it delivers the best performance when it comes to falling asleep. It also states it’s water resistant but I have yet to spill anything or even sweat so I can’t write to that but I can say I am a very satisfied customer!! ... show more

  • SO SO SO SOFT
Size: Queen Style: Topper Only
My mom got this 4 inch mattress topper a few months ago and i was so jealous. i could go to her house wide awake from an espresso and almost immediately fall asleep on her bed. i used to keep a couple thinner mattress toppers on my bed, but alas i have cats and they eventually tore them up. i decided to get this one since i already know how it feels. Sleeping on it last night after months on a hard springy mattress, H E A V E N !!!!! BUY THIS TOPPER. It’s like sleeping on a cloud ... show more

Size: Queen Style: Topper Only
I absolutely love this topper. My husband and I are older and find that we need something a little softer to sleep on. Our daughter bought a vacation home and provided us a mattress, but it was just too hard to sleep on. So after looking at so many online we decided to purchase the lucid 3 inch topper. I cannot tell you the difference it made. It is soft, yet molds to your body giving support where needed. It is not too heavy that you cannot handle it. We woke up without body stiffness. The reviews are correct when they say no odor. We loved it so much that upon returning home, we purchased another for our bed at home! What else can I say but “Sweet Dreams” ... show more

  • Comfort at an excellent price!
Size: Twin XL Style: Topper Only
I purchased this pillow topper for my son’s college bed. Unlike other reviews, it had no smell and the quality was top-tier. We placed a mattress protector on top of it, so it would be no need to get the topper dirty and it was protected. My son runs track and says after a hard day laying on his bed is like laying on clouds. This was the best investment for your child who is in college to feel comfort at all levels. ... show more
