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.

Firm, but soft in pressure areas. Highly Recommended. Great Support.
Size: Queen
Style: 14"
Pattern Name: Medium Plush
This bed is a lot firmer than we're used to, but it only took a few nights to get used to it. We slept on one at a friend's house and had a good night's sleep, so when I got home, I put this in my Amazon Cart. Fast forward 2 or 3 years later, and when it was time for a new mattress, I made the purchase. Arrived quickly, and was easy to unpackage and place on my existing box springs. I was a little restless the first night because I was simply not used to the firmness. The second night was much better. It seems like every night after that has gotten better. I feel like it is much better for my neck and back than our old mattress (which was a high-end name brand but 12-15 years old). For a while now, I have been feeling pretty crummy every morning upon waking. I must say, I don't really have that feeling anymore, and feel much better in the morning. I feel like I'm getting much better rest at night with less tossing and turning. It's firm, but it's still comfortable and soft on the pressure areas. I would highly recommend this mattress, and I hope they continue to make it because I would like to buy another when this one gets old.

Big Man Review! (Update 1 year)
Size: King
Style: 14"
Pattern Name: Medium Plush
I’m a big man, built like a WWF wrestler. Imagine The Rock with a dad bod gut. I’m a stomach and side sleeper. I’ve been on this mattress for a month now. I got the plush 14’ king size thinking it would be on super soft cloud mode. Plush is a softer medium, softer top but rightfully firm in the middle. There is no bounce to it when you slap it or elbow drop the bed. It absorbs energy, so if your sleeping next to someone you can jump out the bed harder than a Barbarian late for a raid and will not disturb the person next to you. I had 2 different spring mattress for the last 20 years and both of them every so often had my lower back HURTING and hamstrings sore when I woke up. This eliminates that issue completely. The bed conforms to your entire body. No pressure points, keeps your back straight, side straight, and it creates a nice pot hole for your gut if your sleeping on your stomach. Pretty sweet. I used to wake up often to toss and turn and to roll over. This is the first bed for the first time in 20 years I wake up in the same position I feel asleep in for an entire 7-8 hours. No aches, no soreness, no pains and I wake up feeling “aligned”. I get out the bed do alittle basic morning stretch and feel great. I’ve beat my body up from physically working too hard and old exercising injures, this is a well worth it mattress for a big man who needs real support. Now the bed does get softer over time the more you sleep on it I guess it has a long break in period, that’s the only reason I knocked a star off. So if you have back any problems, ham string tightness, feel crooked in other mattresses , in need of a supportive bed, or a big man like me who needs to be cuddled by the mattress, get this. If this was the 3 bears this ain’t mama bears bed in terms of softness, definitely no where near papas, but certainly just right. One year update: oh yeah it’s broken in, takes 6 months before you have to rotate your bed. Now this whole bed is broken in and is more comfortable than ever. It definitely is plush but it takes time. I can see this mattress lasting 10 years easy.

A family member heartily suggested this. I wasn’t keen on buying a mattress online without testing it but I took a chance and I’m glad I did. We have this in two of our bedrooms now and I will buy another when it’s time to replace a third. I ordered the 14-inch medium plush. It’s perfect. I sleep great and feel no more neck and back pain from the previous mattress. Set up was easy. It’s heavy though.

Firm is not my style, my son doesn’t sleep well on this either
Size: Full
Style: 8"
Pattern Name: Medium Plush
4 stars because great quality, just not a good fit for us. I bought this for my sons first “big kid bed.” It was easy to unwrap. No bad odors. It says plush but is still pretty firm. My son is 3 now, we have had it from May 2021 to now Jan 2023 and I’m going to replace it. We can’t sleep in his bed with our son when he wakes in middle of night or is scared of something without three days of aches and pains (at least 3.) He flops all over bed and hates sleeping in it. If you like a firm mattress this is for you. My husband and I have a sleep # bed my and I sleep on a pretty soft setting. Husband is on a medium setting and he also says the mattress is not very comfortable at all. I hope this helps anyone who is on the fence about getting the plush versus firm! I can’t imagine how firm the firm actually is. PS… there were no bugs on ours. When I bought this I read reviews saying there were bugs.

For the money a very nice mattress. We use it in guest room, but it is as comfortable as our main king twin that we paid 5 times more for. Cannot rate longevity as it's in guestroom.

Quality Issues & install/haul away service is false advertising. “They never take old mattress” Quality Issues & install/haul away service is false advertising. “They never take old mattress”
Size: California King
Style: 14"
Pattern Name: Medium Plush
UPDATE: It is two weeks after delivery. The plush/soft assessment below was incorrect. The mattress had just expanded for about a 1/2 hr when I evaluated below. After settling for the afternoon it was harder and after a day was what I would call firm. It has remained that way for the two weeks I have had it. I would NOT call this a plush mattress. The foam does not allow my hips to sink in and straighten my spine, and my back is sore. I am not sure if this is a quality issue, a symptom of the latex like top layer, or this is how the manufacturer designed the mattress. The edges are easier to get in/out of bed than usual soft memory foam. They don't crush down when sitting on the edge. After two weeks, I do not like this mattress and do not recommend it both for lack of plushness/softness advertised as well as the quality issues mentioned below. From other reviews it appears if I return it they'll just refund money and then we're stuck with disposal. Not great considering this thing weighs 100 lbs. I bought a memory foam RV mattress a few years ago from Travel Happy via Amazon and it was soft as described and no quality issues. So...it is not an inherent problem with memory foam mattresses to be firm. This is an issue with this specific brand and mattress design. The delivery options have changed and they don't offer the same service level with haul away now. Very disappointing. I had such high hopes. I will start shopping for another mattress that is (actually) soft. ORIGINAL REVIEW: MATTRESS: See pictures. Quality issues with the cover. Left side is smaller/tighter than the right side. Foam expanded immediately to full height, but tight left side of cover is restricting foam expansion all the way. Mattress is very plush, as described. Maybe too plush. I did want a plush mattress though! [**See two-week update above - firmed up later] DELIVERY & INSTALL SERVICE: Amazon box truck arrived. Installers informed us that we need to remove and haul away our own mattress. They said they “never take away the old mattress.” The bed frame was required to be empty and ready for an install. They would not wait. Since we expected they would remove it, our old mattress was still on the bed frame. SO…they left the mattress at outside our front door. A 100lb box for my husband and I to handle! VERY DISAPPOINTING when the service I selected during order clearly said removal of old, install new, and haul away of old (with limited old haul away exclusions). Interesting when I look now they only offer delivery and unpack. They changed the service after I ordered it. Talk about bait and switch! HORRIBLE EXPERIENCE! And so I have to live with the mattress cover issue? Even if they sent a new cover this thing weighs too much to switch. Ugh!
