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.

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 ... show more

    • Saved me from having to replace a mattress--twice
Size: Queen Style: 2 Inch Pattern Name: Topper Only
When my mom died in the summer of 2022, 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. Ultimately, I slept in that bed with this topper a total of 92 nights, and I was blissfully comfortable for every one of them. This topper 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. Flash forward 18 months: My own bed is causing my arthritis some trouble, but I can't afford to replace it as it's only six years old and was quite expensive. I decided to go for what I know and do what worked last year. I still love this topper. It's deliciously comfortable, not hot, and well worth the money. It only needs to last four years, and it's so substantial, I have no worries about it making that long. ... show more

    • It's Soft
Size: Full Style: 3 Inch Pattern Name: Topper Only
Aug 27th 2024>> Update on foam topper: I've slept on it for a week & its definitely too soft. Im now in search for a topper that's firm. The search continues! ORIGINAL REVIEW>>>I have not slept on my new 3 inch foam topper. I laid it out overnight and it fluffed up real nice. I'm laying on it now and it's definitely comfortable, but I wish it was a bit more firm. I'm kinda surprised as to how soft it it. I may have to see about getting a topper that is firm and place it on top of this new topper. It did have a smell that was bothersome but it didn't last long. ... show more
