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.

You gotta help it along-then it's AMAZING!
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!

Quality and firmness
Super comfortable honestly, it’s firm but soft when you lay on it, has great support on the sides so it doesn’t just sink down. Great quality buy, no complaints.

Not bad but could be improved.
I bought this 3" topper for my king size original TempurPedic mattress (on a platform frame) which is getting up there in age, just as I am. With a bad hip it can be a challenge even on my trusty Tempur to get comfortable. Before shelling out big bucks and going shopping to find a "perfect" replacement mattress, I thought I would try a topper first. It's providing me with a nice, comfortable bed. Just the right amount of softness and support. There is no difference between my Tempur mattress with or without the topper, when it comes to heat retention. It's the perfect thickness for me. Out of the packaging, it expanded just fine. Out in the morning and slept on that night. There was some gassing but it dissipated within a day or two. My suggestions for improvement are related to the cover: 1. It comes with a zipper - but only on ONE SIDE. Try and get the cover off to launder it and then back on - on a KING SIZE topper... Not happening. So I will have to figure out how to keep it clean. Maybe steam cleaning. 2. The corner straps to keep it in place aren't set back (away from the corner) far enough to securely hug the corners of the mattress. So far it's been OK, not much movement but I think it will need adjustment from time to time. 3. The cover material is prone to get caught on jewelry or even fingernails which can create a run similar to what you get with a panty hose. I recommend taking off your jewelry and checking your nails before handling the topper. Beyond that, you really can't beat the price, especially with new & used offers typically around $100 for the King size 3".

Comfortable
Amazing! This topper is soft but firm at the same time and I don’t want to get out of bed in the morning it’s so comfortable. I previously had a foam topper and I woke up sweaty- this topper is very cooling and doesn’t make you overheat and completely conforms to your body. It’s exactly as it appears in the photo. When you first remove it from the packaging, you have to give it at least eight hours to completely fluff up. Just be patient and it’ll get there. Don’t pull it or it might rip. I tried two other mattress toppers before I got this one and had to return the other ones. 10/10

I have a problem about spring mattress because eventually it lowers and sinks in, resulting to q back paon. UNTIL I PURCHASE THIS. honestly, even this topper alone and a solid flat floor. My sleep was wonderful and less backache.
