  • Saved me from having to replace a mattress
Size: Queen Style: 2 Inch Configuration: Topper Only
When my mom died last summer, I traveled across the country to stay at her house and start settling her affairs. The first night I slept in her bed, I was miserable. The bed was absolutely horrible--it was hard, had uneven wear, and caused me significant pressure-point pain that woke me up throughout the night. I knew I was going to be returning to the house several times to work on it, and therefore sleeping in that bed for a total of about eight weeks. There was no way I'd be able to tolerate the discomfort. I thought about buying an inexpensive mattress, but then after much research, I found this topper. A friend unpacked it and set it on top of the bed about a week before I arrived for my next stay, so I didn't experience any of the odor or "rest time" needed for it to expand up to full size--it was ready when I arrived. So...After arriving on a late flight my next trip, I put an extra-puffy cotton mattress pad over this, made up the bed, and turned in for the night. It was absolutely heavenly! I couldn't believe I was in the same bed. This topper (and to some extent the puffy mattress pad cover used with it) converted Mom's miserable bed into a thing of delightful pillowy comfort. The difference in comfort and functionality was stunning. Since then, I've slept in that bed with this topper a total of 31 nights, and I was blissfully comfortable for every one of them. I have only another 14 nights scheduled at Mom's house, so I'll never know how this topper holds up in the long-term, but so far, it has completely transformed a bed that was otherwise unusable. It was worth every cent--which was far less than I would have paid for a whole new mattress. ... show more

  • Very comfortable, no odor
Size: Queen Style: 2 Inch Configuration: Topper Only
Bought the 2 inch thick king for a mattress. I liked it so much then bought the 2 inch queen for another bed. The size fit perfectly. There was no odor and it only took several hours to get its full shape. I read all of the reviews good and bad and I think the 2 inch is probably the best option. I can see where the 4 inch would be too thick and you would sink into it too much. ... show more

  • Comfortable sleep with some caveats
Size: Queen Style: 3 Inch Configuration: Topper Only
The memory foam aspect of this topper does exactly what's intended, no argument there. My only issue with it was the cooling aspect. It certainly had the tendency to break out the night sweats .

  • flip over my old mattress and put this on top gives medium firmness
Size: Twin XL Style: 2 Inch Configuration: Topper Only
I have a foam mattress with 1 inch memory foam on the top, so it is too firm. So, I got this 2 inch mattress top. Now, after put it on top of my mattress, then it equivalent to 30 inches of memory foam, which is too plush for me... then I just flip over my old mattes and then add this mattress top, now it gives me the firmness I needed. ... show more

  • Oh! Lucid where have you been all my LIfe???
Size: California King Style: 3 Inch Configuration: Topper Only
Ok, so I purchased this Lucid 3 inch topper in Cal King! Right out of the box there is a slight smell but it's a "new foam" smell nothing out of control. The item was wrapped perfectly with a mesh fabric protector (dispossable) and a nifty letter type opener so you don't have to worry about damaging your item. It was easy peasy! Just open it up, lay on floor, unroll and almost instantly my topper got to it's 3 inches. I popped my ceiling fan on to speed process although I will odbide by the recommended 48 hrs to sleep on. I hope I can make it that long cause I did lay on it briefly on the floor and was in Heaven. I literally closed my eyes for a moment and thought I was on a puffy encompassing white cloud. I swear I could hear angelic voices and see Pegasus flying around me! l'm super hopeful this will help my lower back and hip pain. I was diagnosed with fibromyalgia and anyone who knows about that, You know about the wide spread pains we get. Those evil little fibro elves that man each joint and take turns stabbing you with little miniature knives. Ugh! I HATE them! Lol I really appreciate the construction of this topper. The fact that it's infused with charcoal is an added antimicrobial and moisture barrier benefit. It seems awesome but only time will tell. I'm in my 30s and about 118lbs but sleep heavy. My hubby is about 175 ish and tosses every 10 min. He has horrible neck pain and lower back pain. (Too many years of playing Hockey) So, we are both looking forward to some much needed sleep therapy.There is a 3 year warranty on it so that makes me happy. I will update after a full weeks sleep. Only CON I can see this far is I wish there was a bamboo zippered cover for it. May need to purchase deep pocket sheets.This is a COMPLETELY unbiased review, purchased by me. Who genuinely is super excited about using this item. Check back for update! May 24 UPDATE: Man oh man! Did this item truly exceed my expectations. This topper has been heaven sent. It has completely overhauled my joints in a way that they actually feel less tender and sore. That lower back pain has decided to pack up an move. My fibromyalgia episodes seem less due to being more well rested. With joint pain and wide spread pain lessened I have been able to slowly start doing yoga again. I just needed my body to repair a bit first and this topper definitely helped. My kids call it the marshmallow bed and fight over who gets to nap in it lol. It does help wick away moisture. Especially when paired with bamboo sheets. I will replace after warranty is up in 3 yrs to make sure I'm receiving the best from this product. I can't rave enough. I will update again in 6m. Please don't hesitate you found the one. I will say if you are over 300lb try going up to a 4-5 inch topper for added support. Blessing for better sleep to all... ... show more

  • Passed out in less then 10 min
Size: Full Style: 3 Inch Configuration: Topper Only
This mattress topper arrived and I immediately put it into a topper sleeve I order, made my bed and then laid in it. I remember sighing because of how comfortable it was compared to my mattress. And then passed out from 4pm until 8pm. I was thoroughly impressed. The following day after work I was sitting in bed and passed out from 3pm till 7pm. When I woke up I thought it was 7am and thought I was late for work, but I wasn't. Needless to say this mattress is what my adult self needed badly. I sleep well and wake up rested, but wishing I could jump back into bed :) ... show more
