Perfect for me!
I love this mattress. It is medium firm as described. It fully expanded in about 36-48 hrs with now issues. Have slept on it now for about 2 weeks.

Great Price! Good Quality! Easy Set Up, but plush is a little too plush for me
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.

Nice bed. Sewing needle found sticking out of it
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

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.

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.

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!

Not 14", Irregular, Firm, Good Quality
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.

Best purchase!
This mattress is one of the best purchases I made and if you are a heavy set individual you don’t have to worry about the mattress sagging as it comes right back up. The quality is amazing and long lasting and feels like you’re sleeping on a cloud!

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.
