Relief for pinched nerve pain
I have very typical degenerative disc problems and often will get bulging (or worse) disc issues. For about a year it can cause a pinched nerve feeling down my right hip. For reference, I am 68 nearing 69, 5โ2โ and weight about 115. I am a side sleeper and put a special pillow between my legs.We recently bought a great adjustable bed with a local factoryโcustom made coil firm pillow top mattresses. Split king. I love the bed and mattress. I wanted more softnesses on top because of this back problem so I tried a few tops in addition which helped a bit but not as much as this one. I bought the 2โ topper. I canโt go too soft. That makes matters worse if I am having real pain. I have to say this is just perfect. It doesnโt sink to nothing when I lie down on it. It is a bit firm yet conforms to me and really helps when my back and that hip is particularly tender. Just soft enough and yet firm enough. Of course this is a completely subjective review-but I will give you a sense of it if I can.When I have ruptured discs, the pain is off the charts. I had childbirth in Army hospitals, they gave you nothing but TylenolโIโd take childbirth over this pain (at its worst) any day.I rarely get to that level thank heavens, but I can aggravate it and sometimes even touching my hip (the pain will shoot down my hip)โitโs a dull throbbingโcan make me lose sleep.I canโt take NSAIDS - the only thing I am supposed to take is Extra Strength Tylenol. I will sneak an Extra Strength Excedrin but due to stomach issues am not advised to by my doctor.Resting, lying down and keeping my spine aligned usually helps towards healing.This topper helps me get comfortable for example-when I did too much unloading our RV after a recent trip.Just a lovely almost floating feeling.The other thing isโno odor when I opened it. I have been doing memory foam since before anyone knew what it was. I donโt even mind the off-gassing. The fact is, there wasnโt any with my topper. I opened it in the spare bedroom and it went from flat as paper to itโs full two inches in a few hours and I couldnโt smell anything even though I left it in that room for over 48 hours.I am very, very happy with my purchase. Happy with the cover, density of the foam and quite surprised by no smells. Great price too!

A Comfortable Upgrade for Better Sleep
I bought this mattress topper hoping it would help with my back pain, and Iโm so glad I did. It adds just the right amount of cushioning without feeling too soft, making my bed much more comfortable. I wake up feeling more supported and rested, and it has definitely made sleeping more enjoyable. It was easy to put on, stays in place, and feels like a great value for the price.

This thing is incredible!
I am absolutely in awe of this, & I rarely leave reviews unless something is absolutely horrible and Iโm trying to warn people, or something is fantastic and I want to help people- thatโs it.The fluffiness and comfort level for this is out of this world! My 9 year old autistic son LOVES it, and heโs so picky when it comes to textures and things like that. The value for money is beyond words. The feeling of cooling is just right. Itโs so soft, and the appearance looks so aesthetically pleasing (even though it goes under a sheet). I highly recommend this thing. Weโre buying another for our queen size bed next.It seems like itโs going to be durable.If anything changes, Iโll update my review, but so far so GREAT.

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".

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 :PIt'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 ๐คฃ. 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 ๐คฃ. Jk. But I am ๐I 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!

Slides off the bed. Needs better elastic straps to hold it in place.
Very comfortable. Thick and springs back to shape quickly.The fit is good supports my back well.It slides off the edge off the edge of the bed, i fell off the bed in my sleep a few nights after i got it.The elastic straps at the 4 corners are way too short. I cannot see the straps fitting any bed

Very nice 3: mattress topper: good quality
Very nice 3" topper we put on a pull out to GREATLY add comfort. I bet most of us that have slept on a pull out sofa or bed did not think it provided the best night's sleep. I certainly have not until we learned to put a 3-4+ inch mattress topper over the typically flimsy mattress where you can feel every bar that goes across your 'bed' (if you can call it that). So good toppers turn an otherwise bad night into a good one and this is no exception. Since buying this one, we've had several different guests use our bed and they all claimed to have gotten a good night sleep and never felt anything out of sort. I also like that the cover has straps that hook around the existing mattress to hold it in place.Yes, I'd rather 4,5 or even 6 inches of a mattress topper but this does the trip and it's MUCH easier to store. I can actually squish it into an extra large plastic heavy duty trash bag to store it.

Ideal for adding plushness to existing mattress
Found the pad extremely comfortable and slept well. Recommend this mattress pad if you want to add plushness to your existing mattress.

BEST PURCHASE
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.

Good Medium Support
It puffed out to its full form same day. It has a medium support feel without being bulky and sinking too deeply into it.. No weird smells or off gassing. I would recommend!

Good for back sleeper, fixed my lower back pain
After sleeping on it for a few weeks now, I can say with confidence that it is pretty good. I had lower back pain when waking up with my mattress but after putting this mattress foam cover I no longer have back pain when waking up. I will however state that my girlfriend has said to me that sleeping on the side is less comfortable for her.
