Description

A mattress upgrade shouldn't require a second job. The Lucid® 12-Inch Gel Memory Foam Mattress delivers a premium sleep experience without the premium price, available in Medium Plush or Medium Firm. The Medium Plush version features cooling gel and refreshing bamboo charcoal infused memory foam that contours closely to the hips, shoulders, and back, a medium plush mattress built to cushion pressure points and give side sleepers the sink-in comfort they want. The Medium Firm version balances that same comfort layer against a solid high-density support base—a medium firm mattress versatile enough for back sleepers who need lumbar support and side sleepers who still want pressure relief. Both include a transition layer and are compatible with adjustable bases. 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, Queen, King, and California King.

    • Great Price! Good Quality! Easy Set Up, but plush is a little too plush for me
Size: Twin XL Style: 14" Pattern Name: Medium Firm
GREAT mattress for the price! Mattresses arrived safely and vacuumed sealed. No bad off gassing smells! I've purchases three of these within the past 6 months. The first two I purchased in January of 2026. So far so good! I used each with the Tami Tami power adjustable base with no issues. Only time will tell how they hold up in 5 years. I will say that if I had to do it again I would probably opt for the firmer version as the plush sinks a little too much for my liking depending on mine and my wife's sleeping position. They are very easy to set up. For the price, I would DEFINITELY recommend them!! We're really hoping they hold up for at least 5 years... we'll see. ... 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

    • Nice bed. Sewing needle found sticking out of it
Size: Twin XL Style: 8" Pattern Name: Medium Firm
Bed is nice but I found a sewing needle left behind in the mattress when I went to lay down on it. Scratched me pretty good. So yeah. Watch out for that

Review Image by Joelle
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

    • 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

    • Firm and comfortable mattress
Size: Full Style: 8" Pattern Name: Medium Firm
It’s well-designed for those who prefer a firmer mattress but still want the benefits of memory foam’s adaptability and comfort. Firm Yet Supportive Comfort: This mattress strikes a great balance, offering a firm feel without feeling rigid. It provides enough support to relieve pressure points, especially for back and stomach sleepers. You get a good level of comfort without sinking too deeply into the mattress. Cooling Gel-Infused Memory Foam: The gel-infused layer keeps the mattress cool throughout the night, which is a real benefit if you tend to overheat. I’ve noticed a big difference in temperature regulation, and it’s much more comfortable than traditional foam mattresses in that respect. Easy Setup and Expansion: Unboxing and setting up the mattress was a breeze. It expanded to its full size within a few hours, and there was minimal odor initially, which quickly dissipated. It fits perfectly on a standard bed frame and doesn’t require a box spring if you have a solid foundation. ... show more

    • Best bed Ive ever bought
Size: King Style: 14" Pattern Name: Medium Firm
My little bundle of joy arrived at 6pm, I could not wait till it got here. The box was in great shape alot of packing tape but non the less it was in was in one piece. I mentioned this because alot of people comment on the box damage. Atlas the bed is out of plastic and on the box spring. It took no time for the bed to expand to 14 inches. I also bought the encasement that was a chore. I have to say i am so happy with our purchase and want to share this wondetful bed with the world. Its firm but soft. My back does my hurt what so ever. My husband tried 3 times to get out of bed but just wanted to stay a little longer. Ive been looking at this bed for over 1 year and im so happy I finally purchased it. You cant go wrong I promise! June 28th update: There is no way I could possibly wait a year to write another review, heck it hasn't been 30 days! I wish I had the words to explan the level of sleep my husband and I get. It's mind blowing! This bed is firm but soft and I cant say it enough one of the best beds Ive ever slept in or purchased. The quality of sleep is awesome and no pain at all. If you are looking for a great mattress look no further. ... show more

Memory Foam 14". Medium Feel. Purchased May 2024. Paid $535 Reviewed after a month. I don't believe the mattress retains heat, however, I haven't used a mattress that does (spring or memory foam) so I have nothing to compare to. There is a very hot sleeper that uses this full time. In my experience so far, retaining heat comes from what we put on top of the mattress. This mattress itself, laying on it the body does not get hot. The 14" mattress, is a little under 13". Measured when new, after a week, and after a month, it never reaches 14". The medium foam is a fair description. It is probably best for a back or stomach sleeper. A side sleeper will need to add a mattress topper or opt for the softer option. Without adding another layer, you may experience shoulder, hip, and back pain. Tested this with people 5'5" to 6'2" of healthy weights. More or less body weight will sink into the material differently. The foam is very comfortable, but after a month it is slightly uneven all around. It's not noticeable when a person lays down to sleep. A clumsy description is if a person lays on the left side, right side, head to toe, the person will sink into the bed differently on each portion. On one area the bed will feel painfully firm to them, in another area it will be very comfortable. The foam seems to be uneven, but it isn't overly noticeable and can be made more tolerable with an adequate mattress topper. With two people in bed, a person moving around wasn't felt by the other. There's a tiny bit of movement, but it was not noticeable when sleeping. After a month it seems softer. I don't know if this is just perception, but it's giving me the thought this product may not last too many years but I may be wrong. There was a bit of a "new from the manufacturer" scent when you walked into the room, but it wasn't bothersome and is now gone. I'm keeping this product. ... show more
