***Edit 05/09*** I realized after rolling and stuffing the topper back into its original box that the topper I received was for a California King. Make sure before you open this thing the sticker reads the size you purchased. Now I will say I received a replacement the very next day and I was able to sleep on it last night. I am changing my 2 🌟 review to a 5 🌟 because of how quickly they replaced it and being able to sleep on it, it was really comfy and I slept so well. My bed is 9 years old but there isn't anything wrong with it, it's just not as comfortable anymore. My boyfriend always complained My bed was too hard and made his back hurt and he said he slept so much better on this 3" mattress topper. This mattress topper is humongous. I ordered a Queen and once it fluffed out it measured way larger than the Queen measurements listed. It's like 85×75. It measures larger than the King sized measurements. It looks ridiculous on my bed and I would have to fold it over the edges or cut the foam for it to fit properly. I'm going to attempt to fold and roll this thing back up to send it off for a smaller size. I will say when I laid on it with the sheets it did feel soft and cool. Fingers crossed the full sized bed isn't too small.

Package arrived on time and was well packed. We removed it from paking and removed shipping plastic, then allowed it expand per the instructions. It had no offensive odor at all; in fact it was a pleasant smell if anything. The next day we placed it onto our mattress (it was easy to placeand it stays in place well), put the sheets on, and at bedtime we climbed in. The topper provided an excellent mixture of softness and support. It has not run hot at night and is very pleasant to sleep upon. It appears to be a very durable topper.

I have tried several cushions for my well used recliner. The SertaThermaGel Cooling -Memory foam oneI just bought is the most comfortable one yet. It is not even two inches thick,,but does the job wonderfully without sinking in too much like old car seats. I do put a pillowcase over it for sleeping. It needs a cloth cover. It has a plastic feeling one.It does not slip and I don't always cover it.I would call this one supportive and somewhat cooling

I bought this Serta ThermaGel topper (3-inch, Full size) to add some life to an older mattress that was starting to feel a bit too firm and lumpy. I wanted something that would offer pressure relief without making me overheat, and this has been a fantastic upgrade. Pros: Instant Comfort Upgrade: The 3-inch thickness is substantial. You definitely sink into it, but it feels supportive rather than just squishy. It significantly reduced the pressure points on my hips and shoulders. Cooling Effect: I tend to sleep hot, so I was hesitant about memory foam. However, the "ThermaGel" technology actually seems to work. It feels breathable and stays cooler than standard yellow foam toppers I've used in the past. Brand Quality: It’s nice to see it’s "Made in the USA." The foam feels dense and durable, not cheap or flaky. It expanded to its full shape pretty quickly after unboxing. No Slip: The texture of the foam seems to grip the mattress well enough that it doesn't slide around too much under the fitted sheet. Cons/Things to Note: Initial Smell: Like almost all memory foam products, it had a slight "new foam" smell right out of the box. I let it air out for about 24 hours before putting sheets on it, and the smell went away completely. Care: The instructions say "Spot Clean Only," so I highly recommend using a waterproof or thick mattress protector over it just to keep it clean, as you can't throw this in the washing machine. Verdict: If you aren't ready to buy a brand-new mattress but need better sleep quality, this is a very cost-effective solution. It turned a mediocre bed into a luxury feel.

EXACTLY what i wanted. My family bought me a similar Serta topper 5 yrs ago after a major surgery. My matress has seen better days. The first one was very comfortable and I was still using it but my large dog digs at the bed before laying down and did rip it. Honestly, the first one was a little too soft. I had a full open abdominal so those muscles were cut and I have bad joints , so sitting up can be tricky. I found you sink in and had to actually roll to get up. This Serta topper is much more comfortable & much easier to get up from because all though soft, it is firmer. It bounces right back after you get up. . It gives but doesn't make you sink. This helps sleeping when you have joint pain. I didnt feel as hot with it as much as the first either but could just be me. It came in a solid box ,( grandkids LOVE the box with the sheep and large flaps lol) compressed, well wrapped and in a duffle bag. It was fully expanded as soon as I opened it. I didnt notice any smells. This was the best sleep I've had in a long time and at this price I've considered buying an extra when it inevitably rips and wears down but I've read some reviews online that toppers didn't fully expanded after stored a long time. Ill just enjoy this till it dies and replace it then. It was very fast shipping also. I HIGHLY RECOMMEND THIS & WILL buy again!

I like it. I’ve slept way more comfortably since I put it on my bed. Looks nice. I let it air out and sit for a day before putting it on my bed and it doesn’t smell bad at all. Not hot. Seems durable. I rotate my mattress every two weeks and it stays nice.

Purchased for my 5th wheel RV mattress(king), which wasn't very comfortable. After opening it up and spreading it out my first thought was, this isn't going to spread out enough to cover the mattress. There was no odor what so ever. I did what the directions explained, which was wait. I think I went out there after 3 to 4 days and it looked great(A little surprised). I waited a couple more days, trimmed off the two bottom corners and put on the sheets. Camped several weeks and it was very comfortable. Make sure and wait, don't rush to sleep on it. A couple days ago I decided to order one for my Cal King mattress in the house. For this size there's about a $106.00 delivery charge so, went with another brand. Wish I could have went with another one of these but not gonna pay that for delivery. I have no idea why I didn't take a picture after it was aired out and completed but believe me, it was perfect.

My decades old Posturepedic mattress was taking a toll on my back. It is just too firm for me to sleep comfortably so I needed help. This 3-inch mattress topper helps. It relieves the stress on my spine caused by my rock-hard mattress and provides some pain relief when I am on my side. Its durability is yet to be determined. The topper feels cool to the touch but after lying on it for a while there is a warmth that seeps through. This might be a function of the topper cover that I bought separately, or it could be a function of the memory foam itself. This is not a deal breaker although I live in the tropics. I think it is value for the money spent. So far, so good. It came nicely packaged in its own bag, a pleasant surprise. It is a tad too soft but has enhanced by sleep quality. Probably a 4-inch topper would have been just perfect, but this works okay. There was a faint "new" smell when the memory foam was laid out to air but that has gradually faded. It seems to bounce back to its original thickness after sleeping on it. Overall, it has provided some softness to a too-firm mattress, which was the purpose of getting it. Durability is yet to be determined.
