Description

A mattress upgrade shouldn't require a second job. The Lucid® 6-Inch Gel Memory Foam Mattress gives you a step up in profile from the 5" while keeping the same no-nonsense medium firm feel. It's still a lean, low-profile sleep surface ideal for bunk beds, RVs, kids' rooms, and trundle frames, but with a touch more cushion. An inch of cooling gel memory foam draws heat away and softens the surface, while the high-density base keeps the medium firm mattress supportive. A strong match for stomach sleepers who need their spine aligned without sinking into the bed. This mattress is safely made in the USA with global and U.S. parts, including CertiPUR-US certified foam independently tested for content, emissions, and durability. It's designed with you and your family in mind, this mattress is fiberglass free and has safely passed all flammability testing in U.S. laboratories. This memory foam mattress is backed by a 10-year limited warranty. A convenient mattress in a box ships easily and works with any flat surface, no box spring needed. Available in Twin, Twin XL, Full, and Queen.

    • Very good for aching back and worn out knees
Size: Twin Style: 6" Pattern Name: Medium Firm
If you get back ache when you get up in the morning, it's time to change the mattress. Indeed, my old mattress had a visible depression in the middle, and was not supporting my back. In addition to this, my worn out knees felt pain, for the mattress is bowed up, when my body weight is placed on it. Since there is not much cartilage left in my knees, this bowed up situation puts undue pressure on the knee joints. Too often I wake up in pain in the middle of the night and gingerly shift the position. If this resonates with you, then you might want to consider this mattress in the 'firm' rating. It's a memory foam, and it hugs your body contour. The whole body, that is every part of the body that is in contact with the mattress, is supported. Even though it is rated "firm," it does not feel hard; it is actually soft--it will readily give to the weight of your body--but it will hold your body up, without being plush. Plush is bad for your back. Your body is not sinking into the mattress. In this sense, it is 'firm.' I slept on it the first night, and I feel already the difference: my back hurts less. I could straighten up, without the great pain I used to feel. I think it will get better and better. So worth the money I paid for it. I will give 5 stars, after I slept on it for a week. For now it is 4 stars. After One Week report: I must say, I am glad I bought this mattress. The morning after the first night of sleep on this mattress, my back hurt less--about one half? As I slept on the mattress, the back pain significantly diminished. After 7 nights of sleep, the back pain is maybe 1/5 of what it was before. I now can get up and straighten myself without difficulty. Good stuff! ... show more

    • Great mattress!!
Size: California King Style: 12" Pattern Name: Medium Firm
This mattress is wonderful. Amazing comfort and well priced. Nice and cool all the time. Was super easy to set up. Just carefully cut out of the package and let expand. I love how well a sheet fits to this bed and don’t come off like traditional beds. Material seems durable so far. Only time will tell. Unsure of the water resistance. Have not tried that. Shipping was quick. Would recommend!! ... show more

    • Good mattress and almost perfect
Size: Twin Style: 6" Pattern Name: Medium Firm
Having used spring mattresses for over 20 years, decided to finally switch to memory foam. This mattress was a good value and after about 2 weeks of use, it has converted me. There were both good and bad that I experienced within the past 2 weeks. The good: --Is firm as any spring mattress I've owned --The length and width fit a Twin size perfectly so it will existing cots, bunk beds, box spring, etc --It comes with a fitted cover and straps in the bottom, and was sealed fully in plastic out of the box --The initial chemical smell didn't last more than a couple of days, and I used a couple of fitted sheets initially and that helped in tue first couple of days --All my existing Twin sheets all fit this mattress --The firmness is perfect for anyone with back problems like me --It stays cooler than my previous mattress so it's more comfortable to sleep --Does not make any squeaking sounds like springs so don't have to disturb the other person in the room when tossing/turning at night. The bad: --It took 2 more days to inflate fully than expected --The height was listed as 6" but after fully inflating it measured around 5.6" to 5.7" --There were no instructions included about washing or removing the fitted cover it came with --Realized quickly that can't sit on the edges of the bed like a regular spring mattress - I slid off when I tried to do this on this mattress Overall a great bargain, and almost perfect in every way. Will consider replacing all my future mattresses as they expire with this brand. ... show more

    • A Surprisingly Comfortable Sleep Experience!
Size: Queen Style: 8" Pattern Name: Medium Firm
I recently purchased the Lucid 8 Inch Queen Firm Memory Foam Mattress, and I couldn't be happier with my decision. This mattress has completely transformed my sleep experience for the better. First and foremost, the firmness level is just right. It provides the perfect amount of support for my back, ensuring a comfortable and restful night's sleep. I wake up feeling refreshed and without any aches or pains. The 8-inch thickness strikes a great balance between support and plushness. It's not too thin to feel the underlying structure, yet not too thick that it compromises the supportive feel of a firm mattress. The memory foam contours to my body, offering a personalized and cozy sleeping environment. One of the standout features for me is the breathability of the mattress. The memory foam is infused with cooling gel, which helps regulate temperature throughout the night. No more waking up in a sweat – this mattress keeps me cool and comfortable all night long. Setting up the mattress was a breeze. It arrived in a compact box, and once I opened it, it expanded to its full size within a few hours. The quality of materials used is evident, and I appreciate the attention to detail in the construction. As a bonus, the Lucid mattress comes with a soft and breathable cover that is easy to remove and clean. This adds an extra layer of convenience and ensures that my mattress stays fresh over time. In conclusion, if you're in the market for a firm memory foam mattress, the Lucid 8 Inch Queen is an excellent choice. It combines the perfect level of firmness, support, and comfort for a great night's sleep. I highly recommend this mattress to anyone looking to upgrade their sleep experience. ... show more

Now let me start off by saying I have a sleep disorder and typically get about 6-6.5 hours of non consecutive sleep a night. I’ve also been in a high stress situation since Christmas of 2023 which was finally relieved when I moved into this new space. I bought the medium firm 14” mattress and started sleeping on it only a week ago. I’ll be sure to update as time goes on. I needed something more firm as I am definitely a side or stomach sleeper but I didn’t want it to be so firm that I felt like I was sleeping on concrete. I also really wanted a taller mattress since I like to sit on the edge pretty frequently, and I don’t love a low bed cause getting in and out can be difficult... This was perfect. It was super easy to unroll and set up. I left it in my new place for a week before sleeping on it, but I think it would’ve been ready the next day to sleep on. It also didn’t try to hit us in the face when we unwrapped it which was a win. It fit my bed frame perfectly which was expected. It makes no noise, but I’m also the only person sleeping on it so do with that what you will. No smell. Great price for a quality mattress from Amazon. I just need another set of sheets for the thicker mattress, but my 12” set still works for now…LOL I would definitely buy this brand again in the future. I’ll update again in a few months to a year as I typically have chronic back, neck and knee pain that I’m hopeful this will help with. I can say that after a week I’m feeling confident that it’ll only get better. ... show more

    • Well made
Size: Twin Style: 8" Pattern Name: Medium Firm
I ordered this mattress because it was firm. I cannot sleep on a soft mattress due to back problems. This mattress is Very Firm. Too firm if you have Fibromyalgia like I do. But I love it. So I ordered a mattress topper to lessen the hardness on my body. Especially my shoulders when side sleeping because I had a bad fall years ago and injured my shoulder and back. But if you are looking for Firm then this is the mattress for you. No regrets and I highly recommend. It inflated fully in less than 2 days. There was Never any Smell at all. I'm happy I went with my gut instinct to try it out. Update: I purchased the mattress topper and it definitely took the edge off of my Fibromyalgia and Back pain. ... show more
