Perfect Medium Support

The feel of this mattress is just on the plush side of medium. It's not too firm and not too plush, with a conforming top and exceptional support from below.

Premium Mattress, Reasonable Price

You've always wanted one of those mattresses. The ones in life hack-style retail stores with NASA-created materials and an enormous price tag. Lucid® mattresses offer the same technologies at a fraction of the price, so you can jump on your mattress to try to tip a glass of wine, or you can simply sleep better than you ever have.

Breathable Comfort

In addition to the benefits of traditional memory foam, this mattress is infused with gel beads which capture and distribute heat giving you a better night's sleep.

We ventilated the gel infused memory foam layer to create a plusher, more breathable mattress. The ventilation softens the memory foam and allows it to more quickly contour to your body. The pincore holes also increase airflow for better temperature regulation and cooler sleep. A cooler body temperature makes for more peaceful and longer-lasting sleep.

This mattress came shipped in a box about 1/4 the size of a mattress and I couldn't believe the magic when I opened it up and it "grew" to the size of a twin mattress. I figured there would be no way it would be comfortable, but I was WRONG. This mattress is super comfortable and I am so happy to have it. I did receive this mattress for free in exchange for my honest review. I honestly love this mattress! A great choice for someone needing a guest bed (or maybe a college student) who doesn't have a truck to haul a mattress from a store. Convenient and super comfortable!

Best mattress I have ever had!

I received this mattress for free, and let me tell you. This is the best mattress I have ever slept on! This mattress comes in a small box and the mattress is vacuum packed. When you open the box, the mattress inflates and you would be surprised how that big of a mattress could fit into that small of a box! It is so soft but stiff enough to be super comfortable. The first time I laid on this bed, I knew I had to have it in a king size! That will be my next purchase. I finally have a bed that I want my guests to sleep on! I can't say enough good things about this mattress and would definitely recommend it!

Comfy and easy!

From the start this mattress was very easy to transport, being in a box that could fit in any car. Bringing it home was super easy but the rest was even easier. I love how we just had to take it out of the package and let it unroll on our bed frame. After we waited a while it was ready to go! The first night was an adjustment (never sleeping on a memory foam bed before) but after that, I’ve slept great because it is so firm. The one thing that I’m not used to about a memory foam bed is that when sat on, the edges naturally sink down. But overall, it’s a great bed, easy to assemble, and so comfortable to sleep on!

Quality mattress! You'll love it

First off, if you have never had a memory foam mattress, know that they are different than your typical box spring mattress. From my experience, all of the differences are improvements/benefits. When you sit down, lay down, or apply any pressure to the mattress, it will “give” or “sink in” a bit exactly where you apply the pressure. Note, this is a good thing! If you think about a box spring mattress when you lay on it, the whole mattress is likely to “sink in” a little. That means that if there are more than one of you on the mattress, you are going to know it and feel it, especially when one of you rolls over or moves around. With my Lucid memory foam mattress, I can’t even tell my wife is there when she is sleeping next to me. I don’t feel the mattress move when she rolls over. This mattress is solid in the best way possible. It’s not bouncy and offers great support, molding to your body when you’re on it. That’s what makes this bed so comfortable. For those who want your mattress to be extra-extra soft, I would definitely recommend this bed, but also getting a down mattress topper from Lucid. Then you’ll have the support you need, and on the surface it will feel like you are sleeping on a pillow. Personally, I’m more than happy with my Lucid mattress just the way it is, and I would recommend it to anyone.

Great mattress & value!

After 25 years of an old spring mattress I was so looking forward to this mattress and hoping it would help with some mid-lower back issues. 

Pros: This mattress arrived on time, easy to move up the stairs (in a box, will need two people). Very comfortable. The cover is very soft. What a great deal!

Cons: It does still sleep warm--that problem is not completely gone even with the gel foam. I think this will be nice in the fall/winter though!! It does have an odor for at least a week, but it wasn't overwhelming and is completely gone now (had it for just over 2 months). Last, I'm a relatively small person and think this mattress is just a bit firm for me and that may contribute to the fact that my back pain is not completely gone when waking up in the morning--though it is much better than the spring mattress. However I would rather have it just on the firm side as I know it will get softer!

Overall I would recommend this mattress. I was very nervous about ordering a mattress online-but it was such a great deal and turned out to be a very comfortable mattress. A 25 year warranty makes it even better. *Do note that you must get a memory foam waterproof mattress cover and not a regular waterproof mattress cover. I made that mistake and it felt like I was sleeping on a slab of stone because the foam couldn't breathe. Lesson learned!
