Review: Wake up to way less pain and stiffness! - This has been probably one of the best products I’ve purchased through desertcart! SO comfortable and tames down my aches, pains and muscle stiffness throughout the night for better sleep and way less pain the next morning. It does make it harder to turn in bed, and I do get a little warm from laying on it (not extreme warmth), but the benefits are worth it. Others foams I’ve tried aren’t even close to the comfort I get from this product.
Review: Well..., maybe there IS a God...... - Seriously, my prayers have been answered. I only wish I would have thought to invest in this mattress topper while I was pregnant. It might have saved me a huge headache (literally). I've never had much luck with mattresses, but I've never really blamed the mattresses - because I suck at sleeping. Apparently, I'm a contortionist in my sleep and do things with my body that would give little Linda Blair a run for her money. I wake up a million times a night with pains in my head, my neck, my back, my hips, my legs, literally everywhere. However, I've had a friend come over to help with my new baby and I happen to have the same mattress in the guest room that I have in my main bedroom. She brought it up to me one day that her hip and lower back were killing her since sleeping on the mattress in the guest room- even though it is a pretty expensive pillow-top brand. She asked me if I could order her some kind of mattress topper from desertcart and she'd reimburse me. At this point, I had been in so much agony myself that I got two - one for the guest bed and one for mine. And if it weren't for the fact that I only have nightmares, I'd insist that I'm dreaming up this amazing experience with this mattress topper. I mean, I really don't even have words for this thing. I'm not pain free - because, well, it's gonna take a lot of time to undo that kind of damage. But I have noticed a dramatic difference. My body feels so soothingly cradled. I'm not tossing and turning constantly trying to get comfortable. It's just pure bliss. This may sound strange, but it feels like a hug. It does. It really does. Like a hug from the Pillsbury Dough Boy. Some Technical Details: 1) It was very easy to set up. 2) There was only a very faint odor that dissipated almost immediately. 3) I was so desperate to use it that I didn't even wait the full 48 hours as suggested but it seemed to be super plump straight out of the box. The density is perfect for me. 4) It fit absolutely perfectly across my king-sized bed 5) It appears to be of durable quality unlike some toppers I have seen or used in the past that easily shred or discolored. Time will be the ultimate test so I can't 100 percent guarantee this but judging from observation this would appear to be the case. I will update as necessary. 6) It does live up to the claim about not retaining heat and keeping the body a cool and comfortable temperature (which is crucial for a person like me because I practically need to live in an igloo). So yes, I'm very impressed thus far and absolutely I would recommend this to anyone and everyone. I've honestly never been this excited to go to sleep. My fiance loves it and he was a bit upset that I got it in the first place because he loved the mattress the way it was, but now he loves THIS more. And even my little doggie who has become a neurotic mess since my baby was born seems to be a tad more comforted and peaceful sleeping next to me now. Just writing about it makes me want to go upstairs and jump in bed. I'm starting to wonder if they put something inside this thing if you know what I'm talking about, because I'm addicted. Just kidding... Maybe.

## Questions & Answers

**Q: Why should I get a topper?**
A: Whenever your mattress is ready for a refresh, but your wallet isn’t, it’s time for a topper. Or if you wish your mattress is softer, or if you are in a dorm or renting—a topper is a great solution! Upgrade your bed without the hassle.

**Q: Will my topper come in a box?**
A: Yes! We make it easy. Lucid memory foam toppers come compressed and rolled in a box, are easy to move, and set up in seconds. Just unbox it and let it decompress for 24 to 72 hours before sleeping on it.

**Q: What are the benefits of gel infusions?**
A: Gel infusions in memory foam help regulate temperature, so it sleeps cooler than traditional memory foam.

**Q: What height topper should I get?**
A: The 2-inch profile adds a soft layer of support to your mattress. The 3-inch profile is very plush and adds even more comfort. The 4-inch profile is almost like a mini mattress, with an extra deep, plush, sink-in feel.

### ⭐⭐⭐⭐ Good product, good night's sleep, good value, and poodle approved!
*by J***R on November 24, 2019*

About 14 years ago, we purchased a queen-size memory foam mattress (from Costco). It was our first time using a memory foam mattress, and we liked it a lot. Our next home came furnished with a new king bed, so we bought a 2-inch down-alternative mattress topper. It was inexpensive and adequately comfortable. Our home after that came with two new twin XL mattresses on a common frame (comprising an inexpensive equivalence to a king bed). We continued using our 2-inch down-alternative mattress topper. It finally became lumpy, so it was time to get something new. We saw the Lucid 4-inch memory foam topper and decided to give it a try. We find it to be a good product, providing comfort similar to an entire memory foam mattress (like the one we had originally). This topper even fills the small gap between the two twin mattresses, so that it feels like an actual king mattress. The topper is packaged well, and expanded to its full size in about 36 hours. At that time, the slight odor was gone too. We enclosed the mattresses and the topper in a basic mattress pad, and then put on the bed sheet. Inside a mattress pad and covered by a bed sheet, the topper is a bit less pliant than it is when uncovered, so it feels somewhat less cushy than it does on its own. You may or may not notice the difference, but that's purely subjective. We did not find the difference to be objectionable. Since this product is made in China, I was concerned about the chemical composition of the gas that the mattress gives off when it is new. The reason for my concern about this stems from contaminated Chinese drywall that was used in many homes in my area that were built between 2006 and 2008. The drywall gave off toxic gasses that caused health problems, and caused serious deterioration of copper, thus ruining wiring, air conditioning systems, and jewelry! I contacted Lucid customer support to inquire about this. They assured me that the gas given off by the mattress is harmless, but they were unable (or unwilling) to tell me the chemical composition of the gas. We paid $112.49 for the mattress, but less than a week later, Amazon was selling it for $89.99. At $112.49, this mattress topper is a good value. At $89.99, it's a steal! (By the way, if you do not like the topper and want to return it, keep in mind that after it expands to its full size, the topper will not even come close to fitting in the box in which it came.) Finally, our standard poodle agrees that this topper provides good bedtime comfort, and he approves, as shown in the photo!
