I’m pretty particular about my purchases and I did my research. This by far is one of my better purchases! Easy to unpack, not too heavy, and the quality of the foam by Serta is exceptional. Love the 1” mattress cover that comes with it! Mattress foam is 3”. There was a slight chemical odor but we let it air out with windows open for 2 days. Odor dissipated and it’s good to sleep on. In my opinion, this topper was a great price point and very comfortable to sleep on. No more pressure point pain and we sleep great!

I was skeptical about this topper at first and the price deterred me from buying it but I needed a mattress topper and have tried (and returned) others and I was desperate for comfort. Very pleasantly surprised with the comfort level! Only time will tell though if it is worth the price. It certainly is an investment. At this point, I do recommend it.

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 got this mattress topper for my back as my mattress is too firm. I’ve had two spine surgeries and was really looking forward to the contour from the memory foam. It was too much!! I couldn’t sleep on my sides because my legs kept going numb, I couldn’t sleep on my stomach and when I slept on my back, I felt like I was folding into the foam. Maybe i would’ve adjusted if I was able to give it more time..... but the foam topper had the most ungodly smell and it would not dissipate for anything! I would wake up in the morning and my clothes would reek of the smell. It didn’t even smell like plastic, like I was expecting it to, it smelled like an old mildewed basement.

I bought this Sams.com and like another reviewer, the product I received is not a Serta. I have a Serta twin and the one I received in CalKing is not the same, beside the tag says something other than Serta! Unfortunately I took the wrapper off the foam part, but I don't care, it'll be a pain in the butt to return to store 40 miles away, but it will get tied down with bungee cords and back to the store it goes!

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 am VERY Happy with this mattress Topper! I already have a Pillow Top Mattress but it has not been as comfortable as it once was so I decided to buy the Serta 4" Pillow-Top and Memory Foam Mattress Topper and I LOVE IT! I have been getting a great nights sleep again!

We have had this topper for 1 week now and the smell is relentless. It has not dissipated at all, its a very strong smell, almost mildew like. The smell even transfers to anything you lay on the bed, even with a cover and sheet over the topper! Our pillows, sheets and even clothing laid upon the bed will smell like the topper. Its going back to Sams today. As far as comfort goes, I think it is satisfactory, I personally would prefer a bit firmer as its very soft. But for those that like a sink in soft topper, this would do the trick nicely if you can get past the horrible smell.

Our current mattress has a few years on it but it needed some help. Along comes this topper. It helps me sleep much more soundly and is extremely luxurious to the touch/feel. It still tends to migrate around a bit despite the non-slip backing but it’s not too hard to reposition. This just makes me wonder how long this will last so I’ll give it 4/5 stars for now.

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.
