Description
Ready for a better night’s sleep? Sometimes all it takes is the right mattress topper. The Lucid® Bamboo Charcoal Memory Foam Mattress Topper infuses bamboo charcoal directly into the foam, where it actively absorbs moisture and neutralizes odors rather than masking them. The result is a cooling bamboo mattress topper that sleeps fresher and cleaner than standard foam toppers over time. Choose the profile that fits your bed. Two inches gently cushions pressure points at the hips and shoulders—a mattress topper ideal for slightly firm mattresses without deep sink-in. Three inches delivers plush, close contouring across the hips, shoulders, and lower back for side and back sleepers who want a noticeably more restful night. Four inches is the extra thick mattress topper option, built for firm beds, worn-out mattresses, or anyone who wants to completely transform their sleep surface. Precision-cut ventilation channels make this a ventilated memory foam mattress topper that promotes airflow all night long. Ships compressed and rolled in a box — unbox, unroll, and allow 24–48 hours to fully expand. Works on any flat surface. CertiPUR-US® foam is independently tested for content, emissions, and durability, and the entire topper is backed by a three-year limited warranty. Pair with a Lucid® waterproof mattress protector for best results. Available in Twin, Twin XL, Full, Full XL, Queen, King, and Cal King.

Feel like a brand new person!
Size: King
Style: 3 Inch
Pattern Name: Topper Only
The topper looks just like the picture shown. Our bed is years old. The mattress is still in decent condition. It's one the flips over and has a pillow top on both sides. We've always been good about flipping and rotating it. But, time wears on. I have neuropathy and I was noticing that my hands and arms were falling asleep or tingling every morning. I have had to wear braces. Plus my lower back would take a while of creaking to warm up and not be sore. I have one hip that had started to hurt. I'm not getting into the husband's side. We are both healthy and keep in pretty good shape so I just knew some of this was the mattress. Was I ready to spend another $1K or more on a mattress....ummmm....nope! I had slept on a friend's bed who had gotten a memory foam mattress and liked it. Then I started researching the toppers. I have been looking into a topper for months. Figured I would give it a shot. Hopefully sleep better and save a little money. Thank you Prime Day! haha After reading about everything I could and then reading reviews, comparing prices etc, I decided on this. Hallelujah!! I picked this one because it had good reviews on temperature. I run hot so I needed something that wouldn't make me sweat. I liked the bamboo and charcoal features. This came perfectly packaged. Easy to open (provided a razor tool for the plastic) and lay out. There was absolutely NO SMELL. I was worried. I put my face right into it. Nothing. I have a small house so there was no way I was able to stick a king sized topper somewhere for 48 hours, so this only sat for about 14 hours. It did start to expand immediately after being laid out. I already had a pillow mattress cover w/ deep pockets and it fits right over it. I have slept on this for 2 nights so I might be pulling the trigger early on a review, but I will definitely update this if necessary. Night one: I could definitely tell a difference. It was very comfortable. I was worried about too soft or too firm, but like goldilocks, it was just right. It is soft enough that you sink into it, but firm enough that you are not in a hole (if that makes sense). I was not hot at all. Summer is definitely a time to test that out. Night two: I think I liked it even better last night. Just a huge difference. Even lying on it to read. I was comfortable with no aches. Huge difference in the morning. I haven't worn my arm braces and my arms and hands have not had any pins and needles or numbness. My hip has not bothered me and my lower back doesn't feel like I have to oil it up before exercising or just breathing. At this point, I would definitely recommend this topper. I know there are so many out there. My suggestion is don't rush it. Read reviews on and off of Amazon. Going through though, add this one to your list of a possibility. I will add too that I was thinking I would need a 4 inch, but I did read somewhere that someone stated that it feels like you sink further down with a 4inch so I got the 3 and it's perfect for my needs. Sorry so long, but I invested a lot of time into this. haha

Oh! Lucid where have you been all my LIfe???
Size: California King
Style: 3 Inch
Pattern Name: 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...

The Best!!
Size: Queen
Style: 4 Inch
Pattern Name: Topper Only
I cannot say enough good about this topper. Slept on one at my son’s home one night. Got up and ordered mine the next morning. Friends always compliment me on the comfort. And one of the best parts I can move and never disturb the person next to you. Thickness is great! Love the firm yet softness it delivers

Support & comfort are ok but this topper is not cooling at all. If your body temperature runs warm while you sleep do not get this topper.
