THE WORST CHEMICAL SMELL IN MY HOUSE FROM THIS MATRESS. OPENED ALL MY WINDOWS AND THE SMELL STILL LINGERS. AIRED IT ALL DAY IN THE YARD IN THE OPEN AIR, STILL STINKS. GAVE US A BAD HEADACE. BUYERS BEWARE!!!! NOT EASY TO RETURN. HOW DO YOU PACKAGE UP A CUMBERSOME MATRESS AT HOME FOR RETURN, NOT COMING BACK IN MY HOUSE. I RATHER SLEEP ON THE GROUND THAN INHALE THAT HIGH CHEMICAL SMELL ALL NIGHT. ITS SHOULD BE CONSIDERED DAMAGED GOODS.

I LOVE this mattress pad. It is so comfortable and I sleep so well and don't wake up sore every morning. I have it on the least expensive sleep number bed and the combo of the two is wonderful. I bought another for our guest bedroom because I like it so much. However the first mattress had a terrible odor that still hasn't completely gone away more than a month later. The 2nd mattress I ordered had no odor at all. I actually ordered a replacement for the first one because it smelled so bad and just received it yesterday. It has very little odor and I'm sure will dissipate quickly. My advice is to buy this pad! But, if you get one with an odor, order another.

I recently bought a new mattress and wanted a nice topper to go with it. I bought a cheap one on AMZ that was ok. Then a friend recommended I get this one. It was a Serta and had mostly good reviews, so I bought it. Initially, I loved it, but no more. The topper constantly has to be readjusted because it won’t stay in place. It’s such a horrible design flaw that I don’t see myself ever buying another Serta product.

I have been using the Serta 4 inch memory foam mattress topper for many years. I bought them for my sons dorm bed too. I am currently moving and will be leaving my king size bed with topper to my son and daughter in law (they are super happy) I’m downsizing to a queen sized mattress. The best thing about it is I know I don’t have to go spend a ton on a mattress because I have seen this Serta mattress topper turn the oldest, hardest mattress into a sleeping heaven!! They have saved me thousands of dollars on new mattresses, just by adding the Serta topper to the old mattress. I will never own a bed without this topper. Looking for a nice gift to give someone?? This mattress topper will last them for many years AND upgrade their old mattress tremendously!

We bought this over a month ago. After just a few days of use, my husband and I both experienced greatly increased back pain. It is way too soft. No support at all. In addition, it slides all over the bed. I have to remove the bottom sheet and adjust it each time I make the bed. It's super heavy, so that is a very difficult task.

Bought for a very firm memory foam bed that we have on our RV. Unwrapped and placed on the bed, put the cover on and tested it out. I fell asleep right away and did not want to get up. Love the zip cover. Serta 4 inch with pillow top. Really want one for the bed at home now.

I had purchased a 3" memory foam topper from Sams Club several years aago. It was time to replace it. After reading many online reviews, I purchased this Serta 4" topper from Sams Club. It comes with 3" of memory foam and a 1" fiber filled cover for it. The foam in this topper is different than my old topper. It is not as heavy, firm and dense as my old one was. At first I was leery because it seemed different. This new Serta one has a softer breatheable foam and it is easy to turn over and is very comfortable. Our mattress is extremely hard and you must use a topper in order to be comfortable. It comes in a box and the topper is vaccuum packaged into a solid square that feels like concrete!! However, once you remove the outer packaging the foam begins to breathe and expand. BE SURE to read the directions first about unpackaging the product. Mine only took a few hours to totally expand however, I left is lay on the bed for the rest of the day before I put sheets on it and I slept on it that night. I have slept on it only a few nights but I am very happy with this purchase. It is much more comfortable than my old one was. I am so happy I purchased it.

I just moved into a dorm room I was doing a lot of research looking for a good quality and reasonably priced mattress topper. I love this one! only downside is it doesnt have a cooling effect, it gets kind of hot which is why I knocked off one star,. other than that its really comfortable,high quality, and it actually expanded to 4 inches

Bought mine 2 days ago, fully expanded within minutes of taking out of the box, and was ready to be used as soon as we put the cover on it. My wife is a restless sleeper, first time in 22 years I watched her sleep in one position almost through the whole night (got caught up binge-watching the Mentalist :-). If course, she had to ruin it by putting an extra sheet on the cover, which made it counterproductive, but even with it she woke up actually relaxed. The best thing is - after the initial "You spend money on things that don't work as advertised" speech, she hasn't said it again yet, which is impressive with our household standards, haha. Money well spent!

I bought this because I bought a mattress in a box & it felt okay but I wanted to feel like i’m almost sinking in my bed, bought a featherbed before this and it went flat! So I decided to try this mattress pad read all the reviews and debated, finally bought it, I couldn’t love it more, my boyfriend came straight home and fell asleep within 5 mins! DEF BUY IF YOU WANT SOMETHING SOFT!!!
