Description

Memory foam creates a comfortable sleep surface, conforming to the curves of the body to create an individualized experience. This LUCID mattress topper features 3 inches of a specialized memory foam formula that is incredibly plush, airy and responsive. It all started when we infused plush memory foam with a gel material that regulates temperature for improved comfort. A comfortable sleep surface is not only soft, but also breathable. Hundreds of ventilation holes allow air to flow through the mattress topper for a more comfortable climate. This topper is made of high quality memory foam that meets CertiPUR-US standards. No harmful chemicals were used in the production of this LUCID topper.

  • SUPER PLUSH FEEL!
Size: King Style: 4 Inch Pattern Name: Topper Only
Size & Weight I purchased the 4 inch Lucid topper for my 14 inch King Size mattress. It fits well to all 4 corners. The topper is kind of heavy but not impossible to move. According to the box, it weighs 26.85lbs. It will feel heavier because the object is large and the weight is spread over several square inches. To move it, Grip the topper firmly, but with care and you shouldn't get tears or any other issues. Authenticity First, be sure you are buying an Authentic Product from LUCID. It should come in a box marked with the company's name on it, see the images. Likely, some reviews could be showing a blue topper that looks similar to the Lucid Product but it may be a knock off. I've seen some that are light blue like Lucid's, but it isn't the same. It has a knock off name. According to the box, mine was manufactured in Vietnam and came with a booklet and a free mail/envelope opener. ( Should you buy, yours may be manufactured else where ) Packaging & Expansion. The images you see were taken 1 minute after I opening the vacuum bag. I should have taken an image of it in the bag. It was vacuumed down to about 1 inch of uniform thickness. The topper expanded rapidly after opening and it took about 1 minute to fully expand. Again this is a genuine Lucid product. I see of some reporting it taking days or several hours to expand and even having to place it in a higher temp environment for this to occur. My A/C was set at 72dgs and the room temp was the same. Still, it expanded in 1 minute, which is nearly instant. Smell The topper does have a light smell similar to new carpet but it isnt over powering and honestly, after about an hour or so after opening it, I could no longer detect the smell. Feel I chose the 4 inch because I like that " sink in your bed" feel, which can be great for reducing back and neck pain. The 4 inch is super plush. Because the 4 inch is the thickest and softest, you will sink the most. Some will like this and some won't. Some will mention they don't like crawling out of a hole in the bed...honestly I wouldn't want that either so for the best results, I added a plush pillow top sheet cover to mine. This keeps the soft sink feel but allows you to have no trouble getting out of the bed and I couldnt ask for a better combo. IT MADE MY CHEAP 14inch WALMART MATTRESS FEEL LIKE THE SIMMONS BEAUTY REST HOSPITALITY BEDS IN PREMIUM HOTELS! Both of these are breathable and cool so no night sweats! ( this may vary as no two people are the same ) Also if you sleep with a partner, movement on one side of the bed with this topper won't disturb! Final Recommendations I do not recommend buying this topper for completely worn out matresses, or Stomach sleepers unless you have full size body pillows. But if you sleep on your back or sides and you don't want any back pain and you love the sink in feel, then this is your topper. Also be sure to identify your comfort needs BEFORE you buy. ... show more

  • The review to trust - this is the best memory foam topper on the market.
Size: Queen Style: 4 Inch Pattern Name: Topper Only
Let me start off by saying this isn't a paid review. Memory foam's quality isn't just reliant on density. The measure of density of memory foam gives it a Ultra Plush/Plush/Medium Plush/Medium/Medium Firm/Firm/Extra Firm feel. In order for memory foam to BE plush, it has to be low density. The reason Tempur-Pedic doesn't offer low density memory foam (Tempur-ES 4.1 LB Foam & Original Tempur 5.3 LB Foam) is because they distinguish themselves that way. I've used Tempur-Topper Supreme (3" Tempur Original 5.3LB Memory Foam), and it's super high quality, but that Topper is meant for people who like firm mattresses, and I can say the same thing about the 3" Tempur-ES Memory Foam. I've flipped between this memory foam topper, and a Tempur-ES topper. The Tempur-ES is nice, and you can move around easier, but I never feel like I'm being cushioned and like I'm relaxed. You sink in to the Lucid 4" topper, and my body physically relaxes, and I feel cushioned. I wouldn't even go as far to say the Lucid 4" topper is plush, but in order to be a comfortable foam, you will have to sink in quite a bit, or else you're just laying on expensive concrete. Memory Foam is meant to be inexpensive - Memory Foam is cheap to make as they're basically just made of fossil fuels. Don't judge this topper by the price. I first tried a 3" Memory Foam Topper here on Amazon, since the topper had like a 4.9/5 on 100+ reviews, but I don't think that topper was memory foam, and was just basic polyurethane foam. The memory foam had no squishy feeling, and the imprint recovery was almost instant. The Lucid 4" Topper has a fairly slow recovery from imprint time given the Lucid Memory Foam's density. My parents back pains got better when I got them the 4" Lucid Topper. If you're a normal person, and you keep an open mind, then this Lucid 4" Memory Foam Topper is the best thing to make you sleep extra deeper, and sleep longer period or times. I went back to the Tempur-ES topper for 3 months, and that was the dumbest decision I've made in the past few years. My body oozes with relaxation and comfort on the Lucid 4" Topper now, of which never has happened w/ my Tempur-ES topper. Once you get the 4" Lucid Topper, be prepared to be hard to move around if you want to flip over in the middle of the night, but I flip positions 60-70% less w/ the Lucid Topper compared to the Tempurpedic-ES memory foam topper. I use the Lucid King Pillow hybrid as a pillow, the Lucid body pillow I hold on to w/ my arms when I lay on my side, and the basic Lucid memory foam pillow for in between my legs. The side sleep system I use is the best way to sleep. I do hear the Serta Perfect Sleep Luminous Plush Pillow Top is nice, but I can't imagine anything being more comfortable than the Lucid 4" Topper. Enjoy! -Andy R. ... show more
