I did not read the reviews on the Sams site, but just looked at the sheer number of reviews, and the outstanding rating of 4.7 out of 5 stars, and thought we would give it a try, plus, it was on sale for $30 less! We bought this for my boyfriends Motor home that has a fold down Murphy queen size bed, that was like sleeping on a box spring, that made my back pain (and his) even more excruciating than our home bed did. I slept on it for the first night last night with the Serta mattress topper he put on a few days ago, and it was a solid sleep, and not waking up several times throughout the night. I did not want to get up out of bed! Second of all, just very very slight, extremely mild, back pain, and not the "feel like the wind got knocked out of me when getting out of bed and trying to walk" back pain, and moaning and groaning kind of back pain trying to take baby steps down the hall. Just the slightest level of discomfort that was practically imperceptible and unnoticeable, and it was such a vast improvement, that me, like other people want to get it for our home bed that I get intense back pain on, and my boyfriend wants to buy one for his adult son that is a painter with back issues for Christmas that really was impressed with it too! I did not even know that other mattress toppers can have a funny smell, and this one DEFINITELY DID NOT have one. I am extremely sensitive to odors and scents and there is absolutely no noticeable odor at all. My doctor would look at my MRI and say that I have mild to moderate back issues, but I would tell him, it sure does not feel like "mild to moderate", but I had no idea what an extreme difference what you sleep on can make with your back issues. I'm sold on this product - it is totally OUTSTANDING! I'm going to recommend it to my older father that travels and lives on his boat and just had outpatient non-invasive back surgery to PLEASE consider purchasing this product as he has a SAMS membership too!

I bought this as my mattress had sunken and begun to hurt my back. It perfectly provides support, but if you run hot when you sleep, you may consider a different material -- the memory foam (even with the fabric topper) traps body heat. This is especially apparent when sharing the bed with another person.

A couple years ago I ordered a mattress set from Sam's Club. I didn't go with a pillowtop (which I've always had) and I just hate it....too hard. Fine for hubby but my hips just didn't seem to like it at all. Had a hard time sleeping and always woke up with aches....anyhow, decided to get this and see if it helped. (tried a 2" foam topper previously which did nothing to help).... but this, THIS is amazing.....I am so happy that I got it! Hubby doesn't seem to mind it at all and I'm finally getting a good nights sleep. I wake up with no hip pain. It does what it claims and I would recommend this topper to anyone who thinks their bed is too firm and wants a comfy night of sleep. Good job Serta! "zzzzzzzzzzzzzzzzzzzzzz"

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

I bought this in November and I hate it. My back is aching, my hips hurt and I do not look forward to sleeping any more. I am in pain. I wish I had kept my old cheaper memory foam topper but it was starting to shred. More expensive is not always better.

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.

Mattress topper was soft but unfortunately too warm. Both my wife and I found we were sweating from this after adding it and slept better after removing it from my bed. The topper was also about 2 inches smaller for both length and width that our mattress

I bought a king size about a month again and it is so soft I hate it, I sink way down and it is very uncomfortable. If you need a soft topper it’s great but I need something firmer. I have purchased toppers before from Sams club that were former but this one is too soft, I will be returning to Sams clib

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 had bought a firm mattress for my new house and they were way too hard. I bought one of these and it became those most comfortable bed I have ever slept in. I then bought another for the guest room, and I have had positive feedback from company as well.
