Review: Very comfy!! - I purchased the 3” mattress topper and I was pleasantly surprised after one night. I am caregiving for my father and found the bed I sleep in very uncomfortable and would toss and turn all night due to my hips aching. The first night with this mattress topper made a huge difference! I slept all through the night and didn’t wake up with sore hips. The mattress topper seems to be made of high quality material and the firmness and thickness of it is perfect (I am used to sleeping on a tempurpedic). I am a warm sleeper and did not get hot. But it is still winter. I did not notice any bad odors when unpacking it or sleeping on it. I would definitely recommend this topper if you are not looking for a soft squishy bed.
Review: Conforming, cool topper - Took a chance on a cheaper off market topper, and it paid off. I have a very bad back, and this topper has been amazing, it seems very stiff when you first lay on it, then you slowly melt into it and it conforms spectacularly to you. Also I am a furnace when I sleep and it stays cool enough that I don't wake up in a pool if sweat. Not sure if it works for a side sleepers but if you have spine issues it definately does the job and at a very reasonable price point. Pros: Conforms amazing for back sleepers Very cool temperature wise to sleep on

### ⭐⭐⭐⭐⭐ You gotta help it along-then it's AMAZING!
*by A***2 on February 28, 2024*

I've seen reviews that this thing won't expand to it's intended 2 inches, or at all for that matter. I witnessed that as well. But I really didn't want to return this item. So I dinked with it. You gotta stretch it a bit- GENTLY- bc it will rip between the holes on the surface. Not it's fault, I was over zealous :P It's really separating itself from itsself so it can let in the air. It's a bit like moon sand when it's that compressed. After it takes it's air, it doesn't stick to itself anymore. I had mine in sleeping order within an hour and it. is. so. COMFY! I don't even like memory foam because when it first came out years ago, it would hold the shape of my body indent. This does NOT do that! I have a bad back and huge bo@bs, so I can't sleep on my back, or my tummy, but when I laid down on my bed with this topper before bedtime, to check how it felt, just on my back... I was so comfortable I feel asleep right away! The lights were still on and everything 🤣. I only woke up because my daughter was like, "mom, what are you doing?!" I didn't put her to bed yet lol. I just wanted to try the topper after I made the bed. And I don't like the idea of a 'cooling' topper, but it's not what I thought..... I always wake up sweaty, always. And today, I didn't!!!! My bed was warm and snuggly comfy right when I got in and throughout the night but I didn't sweat like I usually do!!! AMAZING!!! And I usually wake up several times through the night, but I don't remember waking up once!!! I just realized that!! I am excited to go to the bed now... How awesome. Don't give up on it right away. This'd is an excellent deal! No weird smells either! Usually there's some kind of chemical smell with these kind of things, not this one. I didn't smell anything at all. You can stretch it but standing on one end and pulling gently on the other end. Just enough to separate itself from itself inside (I took the cover off). The corners need you to use your fingertips and pull the back away from the front, kinda thing. Gently and slowly. You can even hear it letting go of itself, then watch as it does that moonsand thing... You can see it expand right then. Looks cool. I didn't measure mine, just let it litter there a few minutes after releasing all the wrinkles and creases. Comfy!!! My daughter wanted me to order another one just for her to play on in the living room :p I actually rolled across it to avoid crawling when I was putting the cover back on (the zipper is missing the dangly part on all of them I think, on purpose. Just grab it with two fingers on front and back to zip/unzip) and also to make my daughter laugh) My big body did not hurt a bit doing those rolls. I anticipated my spine grinding on the floor underneath the topper since I'd just finished releasing the wrinkles, and I'd only had the thing in possession for an hour (I opened it immediately to give it the anticipated time of 48 hours to expand). After a half hour I checked on it, and it hadn't changed a bit. That's when I decided to dink with it. I recorded some video but don't know if I'll use it since I was huffing and puffing because I'm a fat 🤣. Jk. But I am 😁 I just realized!!! I didn't struggle to get out of bed either!!! I usually wake up wracked with pain!! (Bad back/prev surgeries and procedures). I'll have to pay attention better tomorrow, because that's A HUGE deal!! I'll update if I remember... Wow. So cool!
