  • Great for people with chronic back pain
Size: Twin Style: 3 Inch Pattern Name: Topper Only
For the cheap price I wasn't expecting it to be good, but turns out it is SO comfortable! I have scoliosis and rods in my spine so I was worried it wouldn't be soft enough, but it's amazing. It's so soft you sink into it. Don't be discouraged that it is bumpy when you unroll it. You have to press on it and lay on it a few nights for it to become less bumpy and more smooth. I've never tried memory foam before so it took getting used to, but I love it! ... show more

  • Absolutely love!
Size: Twin Style: 4 Inch Pattern Name: Topper Only
I absolutely love it! I saw a few reviews saying it was "too soft" and that you had to literally lift your body up to get off of it. Wrong! For me, it's the perfect balance of soft yet sturdy. It's cushy and wonderful! (If I wanted a firm top, I would have kept my mattress as is!) No issues with it moving around (requiring readjustment with the mattress) like the last one I owned. I'm very happy! ... show more

  • 2-inch works great
Size: King Style: 2 Inch Pattern Name: Topper Only
I wasn't sure about the 2-inch foam but it does the job quite well preventing sore hips when sleeping on my side. I had a 3-inch before and even though it was very comfortable I felt like I sank down into the bed a little too much for my liking. I am not disappointed with the 2-inch at all!

  • Durable, supportive, and comfy.
Size: Queen Style: 4 Inch Pattern Name: Topper Only
This mattress topper has been great, I originally purchased it to help with comfort during pregnancy and have continued to enjoy it. It provides a significant level of support while still being soft. The biggest issue that we have noticed is that it causes us to sleep very hot. I wish that it had more cooling qualities (or less heat retention). Overall the comfort level has outweighed the heat issue for now. Make sure that you are prepared to buy "deep pocketed" sheets when using thus topper as it does add significant height to your mattress. I would also recommend a waterproof cover if you have children/pets as it is not waterproof itself. ... show more

  • So soft and comfy!
Size: Queen Style: 4 Inch Pattern Name: Topper Only
This topper gave off no smell. It expanded quickly. It's very soft but not too soft- just right! The only thing I would say negative about it is because there is no edge support, you do feel like you're going to roll off if you get very close to the edge.

  • Very comfortable. Holds up!
Size: Twin Style: 3 Inch Pattern Name: Topper Only
I have slept with this topper for three years now, and I still love it. So comfortable! Not hot. Has held up perfectly. I bought the twin 3" topper. I use this on my half of our king size bed. (My husband didn't want one. )

  • sunk, no sleep, dizzy/lightheaded/dizziness, minor muscle aches, wake up sweating
Size: Queen Style: 4 Inch Pattern Name: Topper Only
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. ... show more
