Like sleeping on a cloud – a perfect refresh for my mattress! ⭐⭐⭐⭐⭐
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.

Great value Great topper!!
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!

Mattress topper for value and comfort
I have been absolutely amazed at the quality of of this topper. I have for >that 30 year owned another much more expensive brand and loved it. This one is a very close second to it at a fraction of the cost. I would highly recommend it for the value, comfort, cost, and flexibility. There was absolutely no smell upon arrival of the product.

Super comfy, not much memory
This mattress pad covers our King size Seally mattress very well. I let it air out for one day, and I didn’t notice any weird smell at all. Our mattress is firm, so this pad adds a wonderful cushion. The pad is NOT hot at all, it’s the perfect temperature. People who are saying it’s hot might need to check their sheet material (microfiber is just a fancy word for plastic). Two things: if your mattress is old and crappy, this will not fix it. It provides no support, just softness. The other thing: it’s not really memory foam (hence only 4 stars). It is not very dense, but very soft. Again, works well for me and my firm mattress, but the description is not really accurate!

Comfort and Value!
The mattress pad arrived compressed in a specially-made storage duffle. We spread it out on our guest bed, being sure to flip it over after 24 hours, and it rebounded to its expected dimensions. Our guest reported that it was very comfortable to sleep on. In fact, they decided to get one for their bed at home, they liked it so much!

Hoping this actually cools
I wake up sweating every night. I spent a lot of time going through reviews on these toppers that are suppose to cool. Every topper had mixed reviews so I went with this Serta 3” because it seemed to have more people saying it kept their temp regulated. It has sat for 24 hours . It is a full 3” and seems cool to the touch. Tonight will be the first night I sleep on it so I only gave 4 stars as I’m not sure if it will actually keep me cool or not. Hoping it does all it promises to do.Update: first night sleeping on the Serta topper. I found even though the topper was cool to the touch it did not keep me cool during the night. Still woke up sweating. Also it was advertised as medium firmness. This is not a medium firmness to me. Was way too soft. Not so soft that you get buried in it like some memory foam but definitely too soft for me. I still found myself tossing and turning because my back was aching due to the softness. I will give it one more night but I believe I will be returning this. I am changing my score to a 3 star as I do not believe it delivered what it advertised.Again comfort of a topper is a personal choice. If you like soft cushion and not worried about the cooling aspect this would be great for you.

Ordered a mattress in a box and found it had good support, but FAR too firm so we ordered this topper. In so glad we did! It’s like sleeping on a cloud! The best sleep I’ve had in a close to a decade!

I bought it a month ago and after making an extended research on all of the mattresses that Amazon sell in the budget side, I found this one really comfortable for me, It’s really soft and it feels like a cloud so if you don’t like to sleep on soft mattress this is not meant for you. I don’t really care if it’s cold or hot because I love in a cold place so it’s perfect for me.
