I got 8 hours and 25 mins the first night I used this.
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.

Very good for aching back and worn out knees
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!

Good mattress and almost perfect
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.

Well made
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.

A Surprisingly Comfortable Sleep Experience!
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.

Great mattress!!
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!!

Better than expected
Mattresses are so subjective, so reviews are a bit pointless when it comes to comfort. But I'll just document my experience going from an old ikea coil spring mattress to one of these modern ones. It came rolled up and folded in half in a cardboard box which kind of concerned me as being folded in half seemed like it could affect optimal inflation due to the stark bend down the middle. This turned out to not be an issue at all and it fully inflated with no issues. I let it inflate for about fourteen hours and it seemed ready to sleep on by then. The first night was a bit odd as I'm used to a more bouncy kind of mattress which changes the feel when you walk on it on your knees, roll and reposition, sit on the edge with your feet on the floor, etc. It felt like I was laying on a bed of playdough. It just felt odd at first. I woke up well rested but didn't really feel like it was that comfortable, but I realized after a few nights that I just wasn't used to it. The benefit of this kind of bed is the memory foam gives your body support everywhere so you're not using muscles to stay in any position as the mattress fills in all the space around you and holds you in place. It's subtle though so you don't realize it at first. This helps you sleep better because your body will be totally relaxed when you lay on it. After about four nights I really started to notice less stiffness and soreness in my back and hips that I would have for the first hour or so after waking up from my old mattress. Also, unlike my old mattress, there's no "sweet spot" on the bed that I need to be in. Anywhere I lay on this mattress is supported and comfortable. Overall I am very impressed by this mattress and I look forward to getting nice comfortable sleep for the next several years. Highly recommended.

Perfect firmness!
I LOVE LOVE LOVE this mattress!!! It is so perfectly firm! I don't sink in at all, and its as firm as the floor while also being comfortable and supportive of my spine! I have had the best sleep, each day that I've had this bed, that I have had in months! I gave it 4 days to fill out and the cover seems to be off centre a bit. The first day it looked a little wonky, and by the third day it was clear the cover was not going to adjust properly. This does not, however, affect the supportiveness of this mattress! It looked weird until I put the sheets on it, and now no one would ever know had I not mentioned it here. For the price, this is far beyond worth it.

Cómodo y a buen precio.
La verdad este colchón ha mejorado mi sueño, tengo problemas de espalda y muchos colchones me incomodan, pero en este he podido estar acostada, sentada o de cabeza 🤣 sin problema. Recomiendo dejarlo inflarse las horas que se sugieren y procurar ponerlo en una base de cama totalmente plana (como un box), esto para permitir que todo el colchón permanezca al mismo nivel (recordemos que su función es comprimirse donde mayor peso existe, así que es una buena idea que la presión sea adecuada en toda la superficie). Me gustó y el cubre colchón le da un plus.
