Review: I’m going to be hearing about this the rest of the year, I just know it. - Well my mom came to me and asked one visit if I could find her a good 4 inch mattress topper for 150.00 or less and since a latex topper was out of the question due to her budget, I immediately thought of Lucid. I don’t actually have a Lucid topper, I have a different brand but when I was searching for my own topper a few years back, I almost went with Lucid because they have a metric ton of reviews and their rating is high and very few of them are negative giving how many purchases there have been. Well let me tell you, I’ve been hearing about this topper every morning for two days. My mom set it up on her bed to let it inflate and expand in the morning and she called me to tell me that half the day later it looked great. She ended up sleeping on it that night and she called raving the next morning to tell me how much she loved it and that she’s never slept better and that she should have ordered one years ago. She said she absolutely I didn’t want to get out of bed and that she couldn’t wait to go back to bed. Well she just called me again this morning, morning too, and you know what she said? “They’re right you really should wait a full 24 hours before sleeping on it. Then she began to tell me how how there is something about this mattress topper. She just can’t explain it, can’t put into words and that night two was even BETTER than night one. “Thank you thank thank you you are the best daughter EVER!!” “You knew exactly what to get me, this is perfect!!” “It”’s so soft and so supportive, it is such a dream!!” Seriously she’s been raving about this topper so much that I absolutely plan on ordering another one for myself lol. Oh let me clarify her mattress situation. She had a mattress that she had put in storage probably 10 years ago. She barely used it. Well she has been using the mattress for a few years and had gotten a topper for a different mattress maybe 5 or 6 years ago. When she moved she brought out the old barely used mattress and was using the topper she had been using but that topper finally broke down and had a dip in it. Her mattress may be fairly unused but it’s old. Kind of like buying a basic smartphone with chintzy features. Sure the device might be brand new but the tech inside is from the electronic Stone Age. That’s her mattress. In the world of mattresses, it’s old tech LOL. This topper and a mattress cover I got to go with, brought that mattress into 2022. She absolutely adores it, so much so that I will be getting one to put on top of my mattress even though I have a 3 inch latex mattress topper. I want to experience “THE DREAM” my mom has been raving about for two days. So not only do I recommend it to you, I recommend it to myself! Just be sure to lay it out and give it a full 24 hours to rise. It will look like a flat lumpy pancake when it first comes out the package, believe me, it fills out to fabulous awesomeness after 24 hours. Review: Supportive and plush! A perfect topper! - Perfect!

The open-cell foam structure and ventilation channels also promote airflow for a cooler sleep experience than traditional memory foam. **Q: Is there an odor when it arrives, and how long until I can sleep on it?** A: A mild new-foam scent is normal and fades quickly. Unroll in a ventilated room for 24–48 hours. By the time it fully expands, the smell should be gone. **Q: Will my current sheets still fit?** A: Measure your mattress plus your topper height before ordering sheets to ensure a snug fit. The added height may require deep-pocket sheets (15"+ depth). **Q: Which thickness is right for me — 2", 3", or 4"?** A: The 2" adds subtle softness to a slightly firm mattress. The 3" delivers deeper pressure relief for back and side sleepers. The 4" is ultra-plush, ideal for very firm or worn mattresses. **Q: Can I wash this topper?** A: The foam can't be machine washed. Spot clean with mild detergent and a damp cloth. We recommend pairing it with a waterproof mattress protector to keep it fresh long-term. ## Customer Reviews ### ⭐⭐⭐⭐⭐ I’m going to be hearing about this the rest of the year, I just know it. *by L***E on February 26, 2022* Well my mom came to me and asked one visit if I could find her a good 4 inch mattress topper for 150.00 or less and since a latex topper was out of the question due to her budget, I immediately thought of Lucid.

A perfect topper! *by C***Y on October 1, 2026* Perfect! This is plush and sooooooo comfortable! It cushions my body perfectly. This topper is supportive and plush allowing for a great sleep. Thank you! ### ⭐⭐⭐⭐⭐ The review to trust - this is the best memory foam topper on the market. *by A***R on January 26, 2022* 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.
